What is in-browser PDF translation?
Convertilo translates PDF documents with a neural model. You upload a PDF, we extract the text, translate it, and show it side-by-side with the original page by page. The source layout stays in view — useful for contracts, medical records and legal documents.
About PDF translation
PDF translation in Convertilo runs in three stages: text extraction via PDF.js, neural translation, side-by-side rendering. Supports 16 languages. Files up to 30 MB.
How translation works
- Text extraction from PDF via PDF.js — page by page, preserving structure
- Neural translation that takes sentence context into account
- Side-by-side view: PDF page thumbnail next to the translation
- Download translation as TXT with page-level markup
- The uploaded file is needed only to extract its text and is not kept

PDF Translation FAQ
Where does my PDF go during translation?
We ask for no registration and keep no uploaded documents. The file is needed only to extract its text and show the translation — nothing remains once you close the tab.
Is PDF layout preserved after translation?
No, the translation is text-only. We show the translation next to the original page in side-by-side view. Producing a translated PDF with preserved layout is a high-complexity task; commercial engines handle that.
Which languages are supported?
English, Russian, Ukrainian, German, French, Spanish, Italian, Polish, Czech, Portuguese, plus 6 more. Direct pairs: en↔ru, en↔uk. Others pivot through English.
What is the maximum PDF size?
30 MB. Large documents (200+ pages) take longer — translation runs page by page and progress is visible as it goes.
Can I download the translation?
Yes, as TXT with page-level markup. DOCX export is on the roadmap.
