10 Best Software for PDF Translation in 2026
A basic translator may extract the words but leave you with a poorly formatted document. Scanned PDFs create another problem because the translator must use optical character recognition, or OCR, before it can read the text.
The best software for PDF translation in 2026 can translate complete documents, preserve most of the original formatting, and handle scanned pages. Some tools are completely browser-based, while others include PDF editing, team collaboration, and professional localization features.

1. DeepL
Best for: Accurate translations and professional documents
DeepL is my first recommendation for most people who care about translation quality. Instead of forcing you to copy text from a PDF, it can translate the complete file and recreate it in the selected language.
The software is particularly useful for reports, business documents, research material, and text-heavy PDFs. It tries to retain the document’s headings, fonts, images, and general page structure.
DeepL also allows paid users to apply glossaries. This is helpful when a company name, technical term, or product phrase must be translated consistently throughout a long document.
According to DeepL’s official document limits, its API Free plan accepts PDF files up to 10 MB and 500,000 characters, while the API Pro limit can reach 100 MB and one million characters.
What I like
- Strong translation quality
- Full-document translation
- Good handling of formal and natural language
- Glossaries for consistent terminology
- Support for PDF, Word, PowerPoint, and other formats
What could be better
- Free document translation is restricted
- Some complex tables and unusual fonts may move
- Language coverage is smaller than that of Google Translate
Verdict: DeepL is the best PDF translation software for most text-heavy business, educational, and professional documents.
2. Adobe Acrobat and Adobe Express
Best for: Polished PDFs that need translation and editing
Adobe is a practical choice if you already use Acrobat to manage your PDFs. You can open a document in Acrobat and use Adobe Express to translate the entire file or selected pages.
The biggest advantage is the editing workflow. After the PDF is translated, you can adjust fonts, resize text boxes, replace images, and fix sections that no longer fit the original design.
Adobe says its Translate feature is available in 59 languages and regional variants, including Hindi, Bengali, Gujarati, Punjabi, Tamil, Telugu, French, Spanish, German, Japanese, and Arabic.
What I like
- Translation and PDF editing in one workflow
- Useful for brochures, guides, presentations, and reports
- Can translate selected pages instead of the full document
- Good control over the final appearance
- Convenient for existing Adobe users
What could be better
- Some PDF elements may not translate
- Complex or scanned files can require extra preparation
- Regular use may require a paid Adobe plan
Verdict: Adobe Acrobat is best for professional PDFs that must look polished after translation.
3. Google Translate
Best for: Free translation of simple PDFs
Google Translate remains one of the easiest free options. Open Google Translate on a computer, select the Documents tab, upload your PDF, and choose the target language.
It supports PDF, DOCX, PPTX, and XLSX files. Google’s consumer document translator accepts files up to 10 MB, while PDFs must be no more than 300 pages, according to Google Translate’s official help page.
Google Translate works best with PDFs containing selectable digital text. It is less suitable for scanned documents, image-heavy pages, and complicated layouts.
What I like
- Completely free for normal use
- Very easy to access
- Wide language coverage
- No software installation required
- Good for understanding the main meaning of a document
What could be better
- Does not directly handle scanned PDFs well
- Formatting preservation can be inconsistent
- Limited editing and terminology controls
- Not ideal for confidential or legally important files
Verdict: Google Translate is the best free PDF translator for simple, text-based documents when perfect formatting is not essential.
4. Smallpdf
Best for: Translating scanned PDFs online
Smallpdf combines PDF translation with OCR, making it more useful than a basic translator when your file contains scanned pages.
You can upload a PDF, choose a target language, and request either a full translation or a summary. The tool runs in a browser, so you do not need to install desktop software.
Smallpdf currently advertises full translations and summaries in more than 20 languages. It also supports common formats such as PDF, DOCX, TXT, JPG, and PNG.
What I like
- Built-in OCR for scanned documents
- Clean and beginner-friendly interface
- Full translation and summary options
- Works on Windows, Mac, and mobile browsers
- Other PDF tools are available on the same platform
What could be better
- Free usage is limited
- Supports fewer languages than Canva or Google Translate
- Complex formatting may still need adjustment
Verdict: Smallpdf is a convenient choice for students and casual users who need to translate a scanned PDF without installing software.
5. Wondershare PDFelement
Best for: Translating, correcting, and editing in one program
PDFelement is a complete PDF editor with AI translation features. It can translate an entire document, selected pages, or a particular section of text.
Its built-in OCR can recognize text in image-based PDFs before translation. After the process is complete, you can edit the translated text, change the page layout, add annotations, convert the PDF, or export it in another format.
The online translator supports more than 35 languages, while the desktop application provides additional editing and document-processing features.
What I like
- OCR support for scanned PDFs
- Translate selected pages or complete files
- Side-by-side viewing
- Post-translation PDF editing
- Batch translation for multiple files
What could be better
- The large number of tools may feel overwhelming at first
- Many useful features require the paid desktop version
- AI usage may be controlled through credits
Verdict: PDFelement is one of the best choices when you need to translate a PDF and then make detailed corrections to the finished file.
6. Foxit PDF Editor
Best for: Business users who regularly work with PDFs
Foxit combines document translation with a powerful PDF editor. Its AI translator can display the original and translated versions side by side, helping you compare important sections before downloading the result.
The software is particularly useful for business reports, technical manuals, contracts, and internal documents that may require editing, commenting, conversion, or redaction after translation.
Foxit says its PDF translation tool supports more than 25 languages while preserving the document’s layout and formatting. It also supports right-to-left formatting when translating documents into Arabic.
What I like
- Side-by-side translation review
- PDF editing and collaboration tools
- OCR for scanned documents
- Formatting and layout preservation
- Useful security and redaction features
What could be better
- More expensive than basic online translators
- Excessive for someone translating only one small PDF
- Language support is more limited than some competitors
Verdict: Foxit is best for companies and professionals who want translation inside a complete PDF management platform.
7. Canva
Best for: Brochures, posters, menus, and visually designed PDFs
Canva is not a traditional document translator, but it works well for PDFs where visual appearance matters as much as the text.
After uploading a PDF, Canva converts it into an editable design. You can use Translate to replace the existing text or place the translated version on duplicate pages for comparison. You can then adjust fonts, images, colors, and spacing before downloading the new PDF.
Canva’s translation feature supports more than 100 languages. The feature is included with Canva Pro, although Canva provides one free translation use.
What I like
- Excellent for visually rich documents
- Easy drag-and-drop editing
- More than 100 translation languages
- Duplicate-page comparison option
- Simple PDF export
What could be better
- Not designed for long academic or technical PDFs
- Imported layouts can sometimes shift
- Translation beyond the free use requires Canva Pro
Verdict: Canva is the best PDF translator for brochures, menus, posters, workbooks, and other design-heavy files.
8. Online Doc Translator
Best for: Free PDF translation without registration
Online Doc Translator is useful when you want a quick result without buying software or creating an account. The website supports PDF, Word, Excel, PowerPoint, OpenOffice, and text documents.
It currently advertises support for 109 languages and attempts to preserve the original document layout. It also supports right-to-left languages such as Arabic, Hebrew, Persian, Pashto, and Urdu.
What I like
- Free to use
- No installation required
- No registration required
- Supports numerous document formats
- Broad language selection
What could be better

Verdict: Online Doc Translator is a good free option for everyday PDFs that do not contain sensitive information.
9. Smartcat
Best for: Translation teams and large multilingual projects
Smartcat is designed for organizations that translate documents regularly. It goes beyond basic machine translation by including glossaries, translation memory, team review, and human editing.
The platform supports PDFs, images, Word documents, spreadsheets, presentations, subtitles, and many other formats. Its built-in OCR can also extract text from scanned PDF pages.
Smartcat says its Document Translation Agent supports more than 80 file formats and over 280 languages. Translations can be reviewed by a team member or professional translator before export.
What I like
- Translation memory and custom glossaries
- Team review and editing
- Built-in OCR
- Strong format and layout preservation

Verdict: Smartcat is the best choice for companies translating product manuals, training material, marketing content, and other documents at scale.
10. SYSTRAN Translate Pro
Best for: Technical and industry-specific translation
SYSTRAN has a long history in machine translation and focuses heavily on professional and enterprise use. Its document translation service accepts editable PDFs, scanned PDFs, images, Word files, PowerPoint presentations, and spreadsheets.
One useful feature is domain-specific translation. This can improve terminology handling in fields such as legal services, information technology, finance, and business.
SYSTRAN Translate Pro offers document translation in more than 55 languages and provides a 14-day free trial.
What I like
- Supports scanned and editable PDFs
- Domain-specific translation options
- Preserves the original formatting
- Suitable for technical documents
- Business and enterprise solutions available
What could be better
- Not the simplest choice for casual users
- Fewer supported languages than some general translators

Verdict: SYSTRAN is worth considering when correct industry terminology matters more than having the widest possible language selection.
How to Choose the Right PDF Translator
The best tool depends on the type of PDF you have.
Check whether the PDF is scanned
Try selecting a sentence with your mouse. If you cannot select the text, the page is probably an image. You will need a translator with OCR, such as Smallpdf, PDFelement, Smartcat, Foxit, or SYSTRAN.
Consider the layout
A simple report is much easier to translate than a magazine, menu, or brochure. Choose Adobe Acrobat or Canva when the visual design must remain editable.
Look at language support
Do not assume every translator supports your language pair. This is especially important for regional languages and right-to-left scripts such as Arabic and Urdu.
Check file and page limits
Free translators may restrict the file size, number of pages, monthly document translations, or available AI credits. Compressing the PDF or splitting it into smaller files may help.
Think about privacy
Avoid uploading contracts, medical records, identity documents, financial reports, or confidential company files without reading the provider’s privacy and file-retention policies.
Plan for human review
AI translation can misunderstand names, numbers, technical terms, and sentences that depend heavily on context. Always review the final document, especially when it will be published or used for an important decision.
How to Translate a PDF Without Losing Formatting
- Check whether the PDF contains selectable text.
- If it is scanned, choose a tool with built-in OCR.
- Upload the original file directly instead of copying and pasting its text.
- Select the correct source and target languages.
- Use a glossary if the tool provides one.
- Download the translated PDF.
- Compare it with the original page by page.
- Check tables, dates, prices, names, headings, and page breaks.
- Correct any translation or formatting errors before sharing it.
Even the best PDF translation software may struggle when translated sentences are much longer than the original text. German, French, Spanish, Hindi, and other languages can require different amounts of space, so minor layout adjustments are normal.
Which PDF Translator Is Best in 2026?
DeepL is the best overall choice for accurate translation of normal text-based PDFs. Adobe Acrobat is better when you need to edit and polish the translated document, while Smallpdf is easier for scanned files.
Google Translate is still the most accessible free choice for a simple PDF. Canva works particularly well for brochures and designed documents. Businesses handling large multilingual projects should consider Smartcat, Foxit, or SYSTRAN.
There is no single tool that is perfect for every file. Choose one based on your document type, language pair, privacy requirements, and how closely the translated PDF must match the original.
Frequently Asked Questions
What is the best free software for PDF translation?
Google Translate is a good free option for PDFs containing selectable text. Online Doc Translator is useful when you want to preserve the layout without registration. For scanned files, try the limited free versions of Smallpdf or PDFelement.
Which PDF translator keeps the original formatting?
DeepL, Adobe Acrobat, Foxit, Canva, Smartcat, and PDFelement are all designed to preserve formatting. However, results depend on the document’s fonts, tables, columns, images, and overall complexity.
Can Google Translate translate a complete PDF?
Yes. Google Translate can process PDF files of up to 10 MB and 300 pages through its Documents feature. The document should contain readable digital text rather than scanned page images.
Can AI translate a scanned PDF?
Yes, but the translator must include OCR. OCR identifies the text inside a scanned image before sending it through the translation system. Smallpdf, PDFelement, Foxit, Smartcat, and SYSTRAN provide options for scanned PDFs.
Is it safe to translate confidential PDFs online?
It depends on the service and its privacy policy. Check how the company stores, processes, and deletes uploaded documents. For confidential business, medical, financial, or legal files, use an approved enterprise service rather than an unknown free website.
Can I use an AI-translated PDF as an official translation?
Usually not. Immigration offices, courts, universities, and government departments may require a certified translation completed or verified by an authorized human translator. AI can create a useful first draft, but it may not meet official requirements.
