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. Changing a file type here means a real conversion, not renaming the extension and hoping it opens. If you're not sure which one you need, our guide to changing a file extension, type, or format covers both on Windows and Mac.
Some of these tools run entirely inside your browser, so those files stay on your device and never reach our servers. When a job does need a server, like video conversion, 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. Every tool is free and adds no watermark. Ads cover the running costs, and we keep no record of who you are or what you converted.
