Best PDF Translators in 2026, Compared

Doclingo translates PDF, Word, Excel, PowerPoint, EPUB, subtitle and image files, and can give you the translation alone or a bilingual version with both languages. It says it restores the original layout after translating.

Visitors get 2 free translations a day and registered users 3, with files up to 50 MB. Premium costs $7.76 a month or $52.20 a year and raises the file size to 500 MB. Scanned PDFs work, but the free version only shows a partial OCR preview. Free files are deleted within 7 days and member files are kept for 3 months. It covers 90+ languages.

DeepL translates PDF, Word and PowerPoint files on a free account, and adds Excel, HTML, IDML and more on paid plans. It says the translated file keeps the original formatting, images and fonts. Its limits are per file and counted in characters rather than pages: 5 MB and 100,000 characters on the free account, 30 MB on Individual and Team, and 100 MB on Business.

The free account allows one file translation a month, and those files are not editable. Individual costs €7.49 a month billed yearly and includes 3 file translations a month. For scans, the help centre says PDF conversion uses OCR and suggests 300 DPI, while the PDF feature page recommends the desktop and mobile apps for scanned documents. Pro files are deleted after translation. DeepL lists 114 languages.

Microsoft's PDF translation lives in Azure Translator, a service for developers. Its Document translation feature reads scanned PDFs with OCR and keeps the original formatting, with a warning that longer translated text can reflow the layout. It lists 135 languages for document translation, and 87 of them as targets for scanned PDFs and images.

Files can be up to 40 MB each in batch mode and 10 MB for a single file. Pricing is pay as you go at $15 per million characters, and there is no free tier for documents. Microsoft says it keeps customer data only while processing and then hard-deletes it. Separately, Microsoft 365 subscribers can translate Word files with Translate Document in Word, which opens a translated copy.

Smartcat is a translation platform for companies. AI translation, an editor, translation memory and human linguists sit in one workspace. Its PDF help article accepts files up to 100 MB (its product page says up to 4 GB per upload) and says the translated document keeps the original layout. The same article lists limitations for complex tables, substituted fonts, form fields and right-to-left layouts.

Smartcat advertises 280+ languages. There is no permanent free tier: a 15-day trial gives you 15,000 Smartwords. Paid plans start with Adapt at $1,200 a year, which includes 100,000 Smartwords.

Files can be up to 15 MB on the free Basic plan and 200 MB on Premium. Premium costs €5 a month billed yearly, or €9 monthly, and includes 2,000 AI credits a month. Advanced AI translation uses 30 credits a page, so the monthly budget covers about 67 pages. Files are permanently deleted within two hours of processing.

Smallpdf's Translate PDF works without an account, reads scanned PDFs with OCR, and can translate the whole document or produce a summary instead. Its tool page lists 20+ languages. Its tool page also says images and special layouts do not carry over into the translation, so treat the result as a way to read the content rather than a finished copy.

The pricing page sets a 50 MB file limit for AI tools and a word limit of 25,000 to 35,000 words on free and 100,000 on paid plans, and allows up to 4 free documents a day. Pro costs $9 a month billed yearly, or $12 monthly. The tool page says files are deleted after one hour, while the privacy notice gives that one-hour rule for account users. Smallpdf says it does not use files from its AI tools to train models.

Canva translates a PDF by importing it as a Canva design and running its Translate app, which puts the translation on a duplicate page or replaces the page. PDF imports can be up to 300 MB and 500 pages, and Canva says the import keeps the layout as closely as possible, with fonts sometimes replaced.

Translate gives you one free use, then needs Canva Pro at US$144 a year. Canva imports a scanned PDF as a single flattened image and does not document translating scans. Its pages give both 134 and "over 100" languages, and we found no deletion rule specific to translation.

The Documents tab on translate.google.com is free, and Google's help lists no sign-in step. It takes DOCX, PDF, PPTX and XLSX files up to 10 MB, and PDFs up to 300 pages. Text in images and scanned PDF pages shows up in the output but is not translated. It works on a computer only, not on phones or small screens.

Google does not say whether the layout is kept or how long uploaded documents are stored. For larger volumes it points to the Cloud Translation API, a developer service that charges $0.08 a page for document translation.

Acrobat hands translation to Adobe Express: you choose Convert, then Translate this PDF, and the document opens in Express, which can translate it into up to 20 languages at a time. Express keeps the original fonts where possible and shrinks text by about 25% when a translation does not fit.

Adobe's help warns that translation may be skipped for scanned, secured, large or complex PDFs. Express accepts PDFs under 99 MB and 99 pages. Two of Adobe's help pages give 46 and 59 languages. Adobe does not document the price of this feature or how long translated files are kept, beyond saving them in your Express account.
