Free, no sign-up. Your files never leave your device.
How to convert

When to use it
Read foreign-language contracts, catalogs, manuals and technical documents, or prepare a reference translation for partners.
Tips
Numbers, units and currencies are kept as written; the translation keeps the original page breaks for easy comparison. Chinese, Japanese, Korean and Thai translations download as TXT.
Good to know
Machine translation is best for reference; legal documents should be checked by a professional translator. Only the text is sent to the AI service, after you agree.
FAQ
Is my file uploaded to a server?
The PDF itself is not uploaded. Once you agree, only the text extracted from it is sent to an AI service (Cloudflare Workers AI) for processing; FileCustom doesn't keep the content. Don't use it for confidential documents.
Is the AI always right?
Not always — double-check anything important. Scanned files need OCR PDF first so the AI has text to read.
