Best AI for translating documents (and keeping the layout)

Side by side

Checked October 15, 2026 on each maker’s own page. DeepL showed us euro prices; its price depends on your country.

Google Translate’s Documents tab is the free answer

There’s no need to paste text into Google Translate a paragraph at a time. Open it in a browser, click Documents, and upload the file. Google’s help page lists the limits: Word, PDF, PowerPoint and Excel files up to 10 MB, and PDFs of 300 pages or fewer. You download a translated copy in the same format, so a Word file comes back as a Word file.

Two catches from the same page. It doesn’t work on phones or small screens. And text inside pictures or scanned PDF pages appears in the result but isn’t translated. That matters for an old letter or a certificate, which are often scans.

DeepL when the wording has to sound right

DeepL is a translator built by a German company, and its wording usually reads less stiff than Google’s. A user on r/TranslationStudies who had to translate nearly 60 articles found even the free version needed “minimal edits.” Not everyone agrees: an August thread there is titled “From one of the best translators I’ve used to absolute rubbish.”

The catch is files. DeepL is stingy with them. Its plans page gives the free version 1 file a month (up to 5 MB) and the paid Individual plan, €7.49 a month on a yearly bill where we checked, just 3. Typed text is roomier: 50,000 characters a month free, about 8,000 words. So for a long document, copy it in section by section, or save your one file for the version that matters. DeepL also lists “no data training” as a paid-plan feature, so keep private papers off the free plan.

Already pay for Microsoft 365? Use Word

Word can translate a whole document itself. Microsoft’s support page says Word for Microsoft 365 offers to translate a document written in another language and opens the result as a new copy, so your original stays untouched. It comes with Microsoft 365 Personal at $9.99 a month, which isn’t worth buying for this alone.

Chatbots: good for checking, bad at whole files

ChatGPT and Claude are excellent at the question a translator app can’t answer: does this sentence sound rude, and what does this idiom really mean? Paste a paragraph and ask. They’re clumsy with whole files, though. One user on X asked ChatGPT to translate a 100-page Word file, and it “first said it needed to use a third-party service—Google Translate.” Even the chatbot reached for the specialist.

Scans and comics need a different tool

Because Google skips text in scans, a photographed letter or an old PDF needs text recognition first. Professional translators in an r/TranslationStudies thread on scanned PDFs use paid software called ABBYY for that, and say complicated layouts still need fixing by hand. A small tool recommended in the same thread got an “I agree” reply calling it the best, from another account six months later. That looks like a plug, so we’re not naming it.

For comics, picture books and flyers, PixLate puts the translated words back inside the speech bubbles and labels instead of handing you plain text. New accounts get 5 free pages; after that you pay per page.

Official papers need a person

No AI translation will do for immigration papers. US immigration rules (8 CFR 103.2) say any foreign-language document sent to USCIS needs a full English translation that the translator certifies as complete and accurate, plus a statement that they’re competent to translate. Use the free tools to understand the document, then pay a certified translator for the copy you hand in.
