About Bilingual PDF Translator

A bilingual PDF translator is the better choice when you need to check the translation against the source, not just read it. Researchers reading a paper in another language, lawyers comparing contract clauses and language learners all want the original in view. Upload a PDF and you get both languages together, which also makes it quick to catch a mistranslated line before you rely on it. If you only need to read the translation, Translate PDF gives a single-language copy with the layout kept.

Side by side puts the original and the translation next to each other; Paragraph by paragraph places each translated paragraph right under its source. Under More options, set the source language yourself and add a glossary, one term per line, such as Licensee = Lizenznehmer, so names and technical terms come out the same every time. Use Pages to translate only the chapter you need.

FAQ

Bilingual PDF Translator: questions and answers

What's the difference between the two layouts in the bilingual PDF translator?
Side by side shows the original and the translation next to each other, which is handy for scanning. Paragraph by paragraph puts each translation directly under its source paragraph, which suits careful reading and checking.
How do I use the glossary?
Open More options and write one term per line as source = translation, for example Licensee = Lizenznehmer. The translation then uses your wording for those terms.
Can the bilingual PDF translator handle scanned papers?
It needs a PDF with selectable text. Make a scan searchable with OCR PDF first, then translate it.
Can I use it for free?
Yes. Free accounts get 1 AI task a day for PDFs up to 50 MB; VIP plans come with a monthly allowance of AI credits and a 1 GB file limit.
Are my papers and contracts safe?
Yes. Uploads are encrypted, each job runs in an isolated process and files are deleted automatically after one hour. Nothing you upload is shared, sold or used to train AI.
