Youdao offline translation packs are useful when you can prepare ahead: looking up short phrases during a flight, reading a menu with weak mobile data, or checking vocabulary in class. They are not a full replacement for online translation, especially for long passages, technical terms, photo translation, or voice workflows.
This page does not promise that a specific pack, region, or version will always be available. Pack size, language coverage, pricing, and update status can change, so check the current offline-pack screen inside the app before relying on it.
How to Download Offline Packs
Menu names can vary by app version. Use this as a practical path rather than a fixed screenshot:
Open Youdao Translate
Open the mobile or desktop app and make sure the connection is stable. Offline packs usually need to be downloaded before you go offline. If the app is not installed, choose your platform from the download page.
Open Offline Pack Manager
Look around Profile, Settings, Offline Translation Packs, or Offline Language Packs. If the entry is missing, check whether the app is outdated or whether the feature is shown on that platform.
Select and Download
Download only the packs you expect to use soon. Keep the connection stable, then switch to airplane mode and test a short sentence after the download finishes.
Start Using Offline
After going offline, test text input and dictionary lookup first. If results are blank, return to the pack screen and check whether the pack finished downloading, expired, or needs an update.
How to Check Supported Languages and Pack Size
Offline languages and file sizes can change by version. Do not rely on old screenshots or fixed numbers from third-party articles. Open the in-app offline-pack list and check the current size, update date, and availability.
| Language | Size / Status | Includes | Translation Direction |
|---|---|---|---|
| English | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ English |
| Japanese | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ Japanese |
| Korean | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ Korean |
| French | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ French |
| German | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ German |
| Spanish | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ Spanish |
| Russian | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ Russian |
| Portuguese | check in the app | Dictionary + Phrases + Translation Model | Chinese ↔ Portuguese |
Storage Space Requirements
Offline packs use local storage. Instead of memorizing fixed MB numbers, check each pack size before downloading and keep room for cache and updates.
Storage Management Tips
- Download offline packs over Wi-Fi to avoid consuming large amounts of mobile data.
- If your device has limited storage, download only the 1-2 language packs you need most.
- Language packs you no longer need can be deleted anytime from the offline pack manager to free up space.
- If a pack shows an update prompt, read the note first; before traveling, update over Wi-Fi and test offline once.
Best Use Cases
Offline translation is particularly valuable in these scenarios:
Airplane Mode
Continue using translation and dictionary features during flights with airplane mode enabled
International Travel
Translate without Wi-Fi access or a local SIM card while exploring foreign countries
Remote Areas
Keep translating in mountains, countryside, or anywhere with poor mobile signal coverage
Quick Lookups
Instant word lookups in subways, libraries, or anywhere with unreliable internet
Offline translation works best for prepared situations: downloading a destination language before a trip, or keeping a Chinese-English lookup pack for class. For contracts, medical notes, visa paperwork, or quoted academic text, review again online or manually before using the result.
