Translate a large PDF without splitting the file
Most free PDF translators cap uploads near 10 MB or a handful of pages. Upload a long scanned report, manual, or book (up to 150 MB). OCR runs page by page. Free preview, no account. Files over 20 pages continue in the queue.
Upload a long PDF — preview first, then continue page by page
Google Translate and most free tools reject files around 10 MB. Upload a scanned report, manual, or book (up to 150 MB). Free OCR preview, no signup. Documents over 20 pages continue in the processing queue.
Large-file reality check
SERP competitors advertise 1 GB and 5,000 pages. What actually blocks people is Google’s ~10 MB document upload and free tools that stop after a few pages.

Why Large PDFs Need a Different Approach
Generic translators fail on long documents because they process the whole file at once. Page-by-page OCR keeps large scanned files manageable.
Page-by-Page OCR
Each page is extracted and reviewed independently, so a bad scan on page 47 doesn't break the rest of the document.
No Arbitrary Page Cap
Translate 50-page contracts, 200-page manuals, or entire scanned books without hitting an upload limit mid-file.
Bilingual Side-by-Side Output
See the original OCR text next to the translation on every page — so you can spot OCR errors before they become translation mistakes.
Preserve Reading Structure
Paragraphs, section headers, and page flow are kept intact so the translated document reads like the original.
How to Translate a Large PDF in Three Steps
No special setup required. The same workflow that handles a 5-page letter handles a 500-page archive.
Upload Your File
Drag and drop your large PDF — scanned or digital. No need to split the file first.
OCR Runs Page by Page
Text is extracted from each page individually. Preview the first pages for free before committing to the full document.
Review and Export
Check the bilingual output, confirm quality, and download the translated document.
What People Translate with This Tool
Large PDFs come in many shapes. OCR-based translation handles them all.
Technical Manuals
Translate 300-page product manuals from Japanese, German, or Chinese — with tables and numbered sections intact.
Legal Documents
Long contracts, court filings, and regulatory documents often run 50–200 pages. Page-by-page OCR keeps each section reviewable.
Academic Archives
Scanned journal articles, thesis archives, and conference proceedings. Translate without losing footnote numbering or citation structure.
Financial Reports
Annual reports and audit filings are dense and long. Preserve table alignment and paragraph flow across every page.
