Translate PDF OnlineFree AI-powered PDF translation online
Translate PDF online and keep the original layout — columns, tables, figures and fonts stay faithful. Translate PDFs online into English, Chinese, Spanish, French, Italian, German, Greek, Japanese, Korean and Russian. It runs in your browser, so you can translate a PDF online with no install and no setup.
Text-based PDF translation works best when you can select text in the PDF. The OCR Translator recognizes text in scans and images first, then translates—complementing the main pipeline when layout extraction alone is not enough.
What is Translate PDF Online
Translate PDF Online is a web service that translates PDF documents online while keeping the original design. It is built for papers, manuals, reports and books — not plain text dumps — so when you translate a PDF online, you get a faithful, readable result that mirrors the source.
Layout-preserving output
When you translate PDF online, the translated PDF mirrors the original structure: multi-column text, tables, images and headings stay aligned with the source page.
Many language pairs
Choose source and target from a growing set of languages to translate PDF online — fine for academic, legal and professional documents across regions.
Secure, ephemeral storage
When you translate PDF online, files move over HTTPS and are removed on a fixed retention schedule after processing, so your documents do not linger.
History & task recovery
The History panel lists every PDF you translate online, so you can reopen a task without re-uploading the same file while it is still retained.
Why teams translate PDFs online with us
