About FormatVolt

Last updated: November 6, 2026

FormatVolt (formatvolt.com) is operated by D-Publishing Services Ltd (“we”, “us”, “our”).

Our mission

FormatVolt provides fast, free tools for everyday file tasks such as converting images, compressing photos and working with PDFs. We believe simple tools should be easy to use and respect your privacy.

Privacy first

Our tools run inside your web browser. Your files are not uploaded to our servers, so your documents and photos stay on your device.

Open-source software

Our audio tools use FFmpeg (including the LAME MP3 encoder) compiled to WebAssembly by the ffmpeg.wasm project, and our PDF tools use pdf-lib (MIT). The unmodified source code of these projects is available at the links above. Licence notices are included with the files we serve.
