File format conversion
Convert between the document formats people actually exchange — PDF, Word, DOCX, EPUB and more — without installing anything.
Several files can be submitted together and downloaded as one archive. How many run at once depends on your plan.
When to use format conversion
When the original is already a clean digital document whose text can be selected and only the extension is wrong. Converting here is faster and costs fewer credits than going through extraction.
When the text is still part of an image — scans, photos, old vertically-set books — run document extraction first so the characters are recognised.
Batches
Several files can be submitted together and downloaded as one archive; how many run at once depends on your plan. The source format is detected on upload and only the targets that file can actually become are offered, so nothing is rejected after the fact.

Frequently asked questions
Why is the target format I want greyed out?
Targets are narrowed by the source format, and only the pairings in the table above are available. The point is that whatever you can pick is something the file can actually become — nothing is rejected after upload.
Does conversion translate the document too?
No — conversion changes the container, not the language. Use file translation for a translation, and document extraction to recognise text inside scans.
Do I need to install anything?
No. It runs in the browser and the converted file downloads directly.
