Which languages does EasyPDF support?

100+ languages, including all major European, Asian, and Middle Eastern languages: English, French, Spanish, German, Italian, Portuguese, Mandarin, Japanese, Korean, Arabic, Hebrew, Russian, Polish, Turkish, Vietnamese, Indonesian, and many more. Source language is auto-detected, and you pick the target.

How accurate is the AI translation?

Quality is on par with premium services like DeepL Pro on common language pairs (English, French, Spanish, German, Italian, Portuguese), and notably better than baseline Google Translate on technical and legal terminology. For mission-critical content (contracts, medical records), we still recommend a human translator review.

Will the original layout and formatting be preserved?

Yes. Tables, columns, headers, footers, captions, and inline image positions are preserved. Where the target-language text is longer than the source (German typically runs 30% longer than English), our engine adjusts font size and line wrapping to keep the layout intact.

Can I translate scanned PDFs?

Yes. EasyPDF detects scanned content automatically and runs OCR before translation. Works for typed scans in any supported language. Handwritten content has lower accuracy but is often readable.

Is my document confidential?

Yes. Translation runs in our secure infrastructure, files are encrypted in transit and at rest, and we never use your content for AI training. Source and translated copies are automatically purged within minutes of you downloading the result.

What's the maximum file size or page count?

You can upload PDFs up to 200 MB. There's no page limit: documents with hundreds of pages translate fine, though longer documents take more processing time. For very large translations, consider splitting the file into chapters first.

Can I translate password-protected PDFs?

You'll need to remove the password first using our /tools/unlock tool, then translate the unlocked version. We can't translate encrypted content directly because we never store your password.

Does translation preserve form fields and signatures?

Form-field labels are translated, but the field values you've entered remain in the source language (you'd want to refill the form after translation). Digital signatures are preserved structurally but may show as 'invalid' after translation since the signature was tied to the original content.

Can I translate the same PDF into multiple target languages?

Yes. Run the translation tool multiple times, picking a different target each time. Each run is independent and free. Useful for building multi-language documentation from a single source.

How does this compare to DeepL or Google Translate?

DeepL Pro and Google Translate API offer plain-text translation; you'd need separate tools to extract text from your PDF, translate it, then rebuild the document. EasyPDF does the entire pipeline in one click, with layout preservation that those tools don't offer. Quality is comparable to DeepL Pro on common pairs.

AI-Powered PDF Translation That Preserves Layout

Need to translate a contract from German to English? A medical report from Spanish to French? A scanned manual from Japanese to English?

EasyPDF's AI translation engine processes entire PDF documents in seconds, supporting 100+ languages with industry-leading accuracy. Unlike basic translators that strip your formatting and dump text into a wall of plain paragraphs, EasyPDF preserves the original layout: page structure, columns, tables, headers, footers, footnotes, and even the position of inline images. Choose between automatic detection of the source language or specify it manually for higher accuracy on technical or low-resource languages.

The output is a fully readable PDF that looks like the original, but in your target language. Whether you're a freelancer working with international clients, a procurement manager reviewing supplier contracts in foreign languages, a legal team translating evidence for cross-border cases, or a researcher analyzing foreign-language scientific papers, EasyPDF delivers translation quality on par with paid services like DeepL Pro and Google Translate API, but with full PDF formatting preserved and no per-document fees. Translation runs entirely in our secure infrastructure, your file is never used for AI training, and the output is purged automatically after delivery.

100+ Languages, From Major Pairs to Low-Resource Combinations

When You Need to Translate a PDF

Translate Foreign Contracts Before Signing

Receive a 30-page distribution agreement in Mandarin, Korean, or German? Translate the full document in seconds to understand every clause before your legal team reviews it. Faster than waiting on a paid translator and free for the first read.

Localize Technical Manuals and Specs

Engineers working with international suppliers often receive datasheets, BOMs, or installation guides in non-English languages. Translate them into your team's working language with technical terminology preserved.

Read Scientific Papers in Any Language

Researchers and students often hit a wall when relevant papers are published in Japanese, Russian, or Chinese only. Translate the full PDF (abstract, methods, figure captions and all) into your native language to extend your literature review.

Translate Foreign Invoices and Statements

Accounting teams processing international invoices, bank statements, or customs documents save hours per week with automatic translation that preserves table structure and numerical formatting.

Why EasyPDF Translates Better

Most online PDF translators dump your document into Google Translate and return a plain-text mess that looks nothing like the original. EasyPDF takes a smarter, layout-aware approach that delivers professional-looking translated PDFs ready to share. Here's what makes the difference.

Layout-Preserving Translation Engine

Our engine reconstructs the original page layout (columns, tables, headers, captions, even footnotes) around the translated text. Where typical translators flatten everything into one column of paragraphs, EasyPDF recreates a translated PDF that visually matches the source. No reformatting needed before sharing the result with clients or colleagues.

100+ Languages, Including Low-Resource Pairs

Beyond the obvious English/French/Spanish/German pairs, EasyPDF handles less-common combinations like Vietnamese to Polish, Korean to Italian, or Hebrew to Portuguese with quality that matches premium paid services. Auto-detection of the source language saves you a click on multilingual documents.

Built-in OCR for Scanned PDFs

Got a scanned PDF in a foreign language? Most translators choke on image-based documents. EasyPDF detects scanned content automatically, runs OCR to extract the text, and translates it: all in a single pass. Works for handwritten forms (within reason), receipts, ID documents, and old archival material.

No Per-Document Fees, No Page Caps

DeepL Pro charges per million characters. Google Translate API has volume pricing. Most online tools cap free use at 5 pages or 10 MB. EasyPDF lets you translate 200 MB documents as many times as you want, free, with no daily quota or paywall. Perfect for occasional users and high-volume teams alike.

Under the hood

What Happens When You Click 'Translate'

When your PDF enters our translation pipeline, we first extract the text content layer by layer: each page's content stream is parsed into discrete text runs, with their position, font, and styling metadata captured. We then segment the text into translation units (sentences for fluent prose, individual cells for tables, single labels for form fields) so each unit reaches the translation model with appropriate context. Source language detection runs in parallel, comparing character n-gram distributions against 100+ language profiles, with fallback to the user-specified language for ambiguous cases.

The translation itself uses a transformer-based neural model fine-tuned on PDF-specific corpora (legal, technical, scientific, financial), with quality consistent with premium services like DeepL Pro on common pairs and significantly better than baseline Google Translate on technical terminology. Once translation completes, we re-flow the translated text into the original page geometry: adjusting font sizes when target-language text is longer (German tends to expand 30% beyond English), wrapping long paragraphs across new line breaks, and re-rendering the page with the same image positions and table structure. The final PDF is identical in layout to the source, just in your target language.

All processing happens in our secure infrastructure, your file is encrypted in transit and at rest, and we delete both source and translated copies within minutes of you downloading the result.
