Why Use Google Translate Offline on Android
There are plenty of moments when you need a translation and there is no internet connection to help you. You might be on a plane, in a metro tunnel, in a rural area with weak signal, or abroad with mobile data turned off to avoid roaming charges. A street sign, a menu, a medicine label, or a question from a stranger does not wait until you find Wi-Fi.
Using Google Translate offline on Android solves that problem. The Google Translate app lets you download languages onto your phone before you travel, so the translations happen on the device itself instead of on Google’s servers. Once a language is downloaded, you can translate typed text in that language with no Wi-Fi and no mobile data at all. For supported languages, you can also point your camera at printed text and get a translation without a connection.
Offline translation is not quite the same as online translation. The downloaded language packs are smaller than the full online service, so translations can be a little less accurate, especially for long or complicated sentences. Some features need an internet connection no matter what you download, and not every language can be downloaded at all. It helps to know these limits before you travel.
This guide shows you how to use Google Translate offline on Android: how to download a language, translate typed text, camera text, and conversations without a connection, manage downloaded languages, and use offline translation in Gboard and Chrome. It also covers the most common problems. Menu names vary slightly by app version and phone brand.
Before You Start
Offline translation only works if you prepare it while you still have an internet connection. You cannot download a language pack after you have already lost your signal, so do this at home on Wi-Fi before a trip, not at the airport or on the plane.
Step 1: Install or update the Google Translate app. Open the Play Store, search for Google Translate, and make sure it is installed and up to date. An old version may look different from the steps in this guide.
Step 2: Decide which languages you need. You need the language you will be reading or hearing, and the language you want the translation in. If you are travelling to Japan and you speak English, download Japanese and make sure English is downloaded too.
Step 3: Connect to Wi-Fi. Language packs are small, usually around 35 to 50 MB each, but downloading several of them on mobile data can still add up. Connect to Wi-Fi before you start, and check that your phone has enough free storage.
Step 4: Test it before you travel. After downloading your languages, turn on aeroplane mode, making sure Wi-Fi is switched off too, and try translating a few sentences. If the translation works in aeroplane mode, it will work when you are genuinely offline.
One more thing to remember is that downloaded languages are stored on the device, not in your account. If you switch phones, you will need to download the languages again on the new phone.
How to Download a Language in the Google Translate App
Downloading a language is the one step everything else depends on. Without a downloaded language pack, the Translate app has to reach Google’s servers for every translation, which means no connection means no translation. Once the pack is on your phone, the app can translate that language entirely on the device.
Step 1: Open the Google Translate app. Find the Translate app on your phone and tap to open it. If you do not have it, install it free from the Play Store first.
Step 2: Tap the language at the bottom of the screen. At the bottom of the app you will see the two languages you are translating between. Tap the language you want to download to open the full language list.
Step 3: Find the language you need. Scroll through the list or use the search box at the top to find the language.
Step 4: Tap the Download icon next to the language. If the language can be used offline, you will see a Download icon next to its name. Tap it and the download will start. If there is no Download icon, that language cannot be downloaded.
Step 5: Confirm the download if the app asks. The app may ask you to confirm the download. Tap Download to continue.
Step 6: Repeat for your other language. Go back to the main screen, tap the other language at the bottom, and download that one too. Offline translation between two languages needs both language packs on the phone, not just one.
Step 7: Check that the language shows as Downloaded. Open the language list again. A language that is ready for offline use shows as Downloaded next to its name. If it still shows a Download icon, tap it again while you are still on Wi-Fi.
Step 8: Test the download in aeroplane mode. Turn on aeroplane mode and switch Wi-Fi off, then type a sentence in one of your downloaded languages and translate it. If you get a translation, the offline pack is working.
How to download a language without Wi-Fi
By default, the Translate app only downloads languages over Wi-Fi. If you need to download a language using mobile data, open the Translate app, tap the menu, then Settings, then Data usage, then Downloaded languages. There you can choose Ask before downloading, which makes the app ask each time, or Use Wi-Fi or mobile network, which lets it download on mobile data without asking.
How to Translate Offline with Camera and Conversation
Typed text is the most reliable thing to translate offline, but it is not the only thing. The camera can translate printed text such as menus, signs, and labels without a connection, as long as the languages involved are downloaded and the camera feature supports them. Spoken conversation is the trickiest feature offline, and it is the one most likely to disappoint if you have not tested it first.
Step 1: Make sure both languages are downloaded. Open the Translate app and check that both the language you are translating from and the language you are translating to show as Downloaded.
Step 2: Type your text as normal. With no internet connection, type or paste the text you want to translate into the box at the top of the app. The app will translate it automatically using the downloaded language pack.
Step 3: Tap Camera to translate printed text. At the bottom of the app, tap Camera, then point your phone at the sign, menu, or label. For supported languages, the translation appears overlaid on the screen, even with no connection. Hold the phone steady and make sure the text is well lit.
Step 4: Use Scan mode for longer or smaller text. If the instant camera view is hard to read, tap the shutter button to take a photo of the text, or choose Scan mode if your app shows it. You can then highlight the exact words you want translated.
Step 5: Import a photo from your gallery. You can also translate text in a photo you have already taken. In the camera view, tap the gallery or Import option, choose the photo, and highlight the text. This works offline for downloaded languages.
Step 6: Try Conversation mode before you need it. Tap Conversation at the bottom of the app, choose your two languages, and speak. The app listens, translates what you say, and speaks the translation aloud. Offline conversation needs both languages downloaded, and it may vary by version and phone, so test it in aeroplane mode at home.
Step 7: Fall back to typing if conversation mode fails. If the conversation feature needs a connection on your phone, you can still hold a simple back-and-forth by typing. Type what you want to say, show the translation to the other person, and ask them to type their reply.
What offline translation cannot do
Some features always need an internet connection, no matter which languages you have downloaded. Translating a whole document, translating a website, and the newest live translation features are online-only on most phones. Voice input can also be limited offline, depending on your phone and language. Google has also said that offline live translation is only available for selected language pairs on some newer Pixel phones, so most Android phones should not count on it.
How to Manage and Remove Downloaded Languages
Downloaded languages take up storage on your phone, and they can go out of date. Google improves its translation models over time, so an old language pack may be less accurate than a newer one. Checking your downloaded languages every few months keeps them up to date and frees space for the languages you actually need.
Step 1: Open the Google Translate app. Make sure you are connected to Wi-Fi before you start, because updating a language pack needs an internet connection.
Step 2: Tap the menu. Tap the menu icon or your profile picture in the app, depending on your version. Menu names may vary by version, so look for Downloaded languages in the menu or under Settings.
Step 3: Tap Downloaded languages. This opens the list of languages stored on your phone, along with the full list of languages that can be downloaded.
Step 4: Update a language if an update is offered. Next to a language, you may see Update if a newer version of the language pack is available. Tap Update to replace the old pack with the improved one.
Step 5: Upgrade a language if Upgrade is shown. Some languages offer a higher-quality language pack. If you see Upgrade next to a language, tap it to download the better version.
Step 6: Remove a language you no longer need. Tap Remove next to the language you want to delete, then tap Remove again when the app asks you to confirm. You can download it again later whenever you have Wi-Fi.
Step 7: Check your storage after removing languages. Each language pack is usually around 35 to 50 MB, so removing three or four languages you no longer need can free up well over 100 MB.
If you are about to travel, do this tidy-up before you leave, not during the trip. Remove the languages you will not need and update the ones you will.
How to Translate Offline in Gboard and Chrome
The Translate app is not the only place offline translation can help you. Gboard, the keyboard that comes with most Android phones, has its own built-in translation feature, so you can translate as you type in any messaging or email app without switching to the Translate app. Chrome can translate whole web pages, but that feature works differently, and it is important to know its limits before you depend on it offline.
Step 1: Open Gboard in any app. Open a messaging, email, or notes app and tap a text field so the Gboard keyboard appears.
Step 2: Tap the Translate icon on the keyboard. Tap the four-squares menu icon on the keyboard toolbar, then tap Translate. If you do not see Translate in the list, check Gboard settings to make sure the feature is turned on.
Step 3: Choose your two languages. In the translate bar, set the language you are typing in and the language you want to translate into. Gboard will translate what you type as you go.
Step 4: Download offline packs in Gboard for travel. In Gboard’s translate settings, you can download offline language packs for the languages you use most. This lets Gboard translate without a data connection, in the same way the Translate app does. Download the packs on Wi-Fi before your trip and test them in aeroplane mode.
Step 5: Do not rely on Chrome for offline translation. Chrome on Android can translate a web page into your language when it offers to do so, but that translation is done online, using Google’s servers. If you have no connection, Chrome cannot translate the page. Chrome has no offline language pack like the Translate app does.
Step 6: Use the Translate app for web pages when you are offline. If you need a web page translated without a connection, copy the text from the page and paste it into the Translate app, where your downloaded languages can handle it.
Step 7: Use Tap to Translate for text in other apps. In the Translate app, turn on Tap to Translate in Settings if your version offers it. Then, when you copy text in any app, a small Translate icon appears, and tapping it shows the translation without leaving the app you are in.
The key point is that offline translation lives in the Translate app and in Gboard, not in the browser. Chrome is convenient when you are online, but it cannot help you when you are not.
Common Problems and How to Fix Them
The language will not download. Check that you are connected to Wi-Fi and that the language can actually be downloaded. If there is no Download icon next to the language, it is not available offline. If the download never finishes, check your free storage and try again on a stable Wi-Fi connection.
Translation works online but not offline. This usually means one of the two languages is not downloaded. Open the language list and check that both languages show as Downloaded, not just one.
The camera shows no translation offline. First, check that both languages are downloaded and that the language supports instant camera translation. Not every language supports the camera feature, and some only support it online. Make sure the text is clear, well lit, and in focus.
Conversation mode does not work without internet. Spoken conversation is the least reliable offline feature, and on many phones it needs a connection even when both languages are downloaded. Test it in aeroplane mode before your trip so you know what to expect.
Offline translations look wrong or too simple. Offline packs are smaller and less accurate than the online service, so long or complicated sentences may come out awkwardly. Try shorter, simpler sentences, one idea at a time. Avoid slang, jokes, and idioms, which machine translation handles badly even online, and much worse offline.
Downloaded languages take up too much space. Each pack is usually around 35 to 50 MB, which is small on its own but adds up if you have downloaded many languages. Open Downloaded languages, remove the ones you do not need for your trip, and keep only the languages you will actually use.
Gboard translation does not work offline. Check that you have downloaded the offline packs inside Gboard’s own translate settings, not just in the Translate app. The two apps keep separate downloads in some versions, so a language downloaded in the Translate app may not be available in Gboard until you download it there too.
Frequently Asked Questions
Can I use Google Translate completely offline? Yes, for typed text in downloaded languages, and for camera text in supported downloaded languages. You need to download each language first, while you still have an internet connection. Features such as document translation, website translation, and some voice features still need to be online.
How many languages can I download? You can download as many as your phone has storage for. Most people only need two or three: their own language and the language of the place they are visiting.
Do offline translations use mobile data? No. Once a language is downloaded, translating with it uses no data at all, because the translation happens on your phone. The only time data is used is when you download, update, or upgrade a language pack.
Does offline translation work in aeroplane mode? Yes. Aeroplane mode turns off Wi-Fi and mobile data, but the Translate app can still use the language packs already stored on your phone. Just make sure Wi-Fi is actually off too.
Is offline translation as accurate as online translation? Not quite. Offline packs are smaller than the full online service, so they can be less accurate, especially for long sentences, rare words, and idioms.
Final Thoughts
Using Google Translate offline on Android comes down to one habit: download your languages before you need them. Get the Translate app up to date, download the language of the place you are visiting and your own language, and test them in aeroplane mode while you are still at home.
Remember the limits too. Typed text is the most reliable offline feature, camera translation works for supported downloaded languages, and conversation mode may need a connection on your phone, so test it first and keep typing as your backup. Keep your language packs updated, remove the ones you no longer need, and use Gboard when you want to translate as you type.
