Your files stay private.
Always.
Trusted by users since 2021. We built ChangeMyFile around one principle: your files are yours, and nobody else's business.
No one except you accesses your files
Every conversion runs in an isolated Docker container. Your download link expires after 1 hour. After that the file is inaccessible to everyone, including us. Files are permanently deleted from our servers within 24 hours. No human ever sees your files.
Zero registration. Zero tracking.
We do not require an account because we do not need to track you. No email address, no login, no cookies beyond what the site needs to function. Convert a file and leave. We have no record you were here.
Free because of ads, not your data
ChangeMyFile is free because we run advertising, not because we monetise your uploads. We have no interest in your files, your metadata, or your conversion history. Your data has no value to our business model.
Built on the same technology as YouTube
Conversions are powered by FFmpeg, the open-source engine trusted by YouTube, VLC, and thousands of professional applications. Your file is processed in a sandboxed container and permanently deleted from our servers once your download is ready.

Yes. All uploads happen over HTTPS with SSL encryption, so your data is protected during transfer. We automatically delete all files from our servers within 24 hours. We don't read, share, or store your files longer than needed.

Each file can be up to 20MB, and you can convert up to 5 files at once (100MB total per batch). Need to convert more? Just run another batch — there's no daily limit on how many conversions you can do.
Most conversions finish in just a few seconds. Larger files or complex formats like video may take a bit longer, but our cloud-based processing keeps things fast. You'll see real-time progress so you know exactly when your file is ready.
It depends on the formats involved. Converting between lossless formats (like PNG to BMP) preserves full quality. When converting to compressed formats (like JPEG or MP3), some quality reduction is normal but usually unnoticeable. For best results, we recommend keeping your original files and using the highest quality settings available.
