About FieldConvert

Free file conversion that never uploads your files.

FieldConvert converts images, video, audio, documents, spreadsheets, archives and fonts, and offers tools such as Merge PDF, Compress Image and image-to-text (OCR). It is free, needs no sign-up and has no daily limit.

Why it is different

Most online converters upload your files to their servers. FieldConvert does the work inside your browser instead, using WebAssembly versions of trusted open-source engines. Your files never leave your device, there is no upload wait, and because conversions cost us nothing to run, we do not need to limit how many you make.
