Free Online File Converter
Convert any file format in seconds, for work, school, or personal projects.
Everything you do with files, in one browser tab.
ChangeMyFile started as a free online file converter and grew into a full toolkit. Convert, edit, compress, record, transcribe, sign, and protect — across audio, video, images, and PDFs. No installs, no accounts, no watermarks. Most tools run in your browser, so your files never leave your device.
Browser-first
Most tools — image edits, audio cutting, PDF merge, voice recording — run entirely on your device. Nothing uploads. For conversions that need a server, links expire in 1 hour and files are permanently deleted within 24.
Free, ad-supported
No accounts. No upsells. No watermarks. Ads pay the bills — your files and your data are not the product. We have no record of who you are or what you converted.
Built on FFmpeg
Server conversions are powered by FFmpeg, the same open-source engine inside YouTube, VLC, and most professional video apps. Each job runs in a sandboxed container, isolated from every other user.
