About us
ChangeMyFile is a free toolkit for PDF, image, audio, and video.
We started in 2021 as a simple online file converter. Today ChangeMyFile handles PDF, image, audio, and video work in one place. You can convert between more than 700 format pairs, compress and edit files, record and transcribe audio, and sign or password-protect a PDF, all without installing software or creating an account.
Most of these tools run inside your browser, so your files stay on your device and never reach our servers. When a conversion does need a server, it runs on FFmpeg, the open-source engine behind YouTube and VLC, in a container kept separate from other users. Download links stop working after an hour, and any uploaded file is deleted within a day.
Browser-first
Image editing, audio trimming, PDF merging, and voice recording run entirely on your device. The files never leave your computer, so they stay private and the tools stay fast.
Free, ad-supported
Every tool is free, with no watermarks and nothing to upgrade. Ads cover the running costs, which means your files and your data are never the product. We keep no record of who you are or what you converted.
Built on FFmpeg
When a job is too heavy for the browser, like video conversion, it runs on a server using FFmpeg, the same open-source engine behind YouTube and VLC, inside a sandboxed container isolated from other users.
