ConvertWhat happens when you convert AVIF to BMP
- BMP is lossless, so nothing more is lost in the conversion. Detail already removed by AVIF compression doesn't come back, and the file is usually larger.
- BMP has no transparency, so transparent areas are filled with a background color you choose (white by default).

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many AVIF files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting AVIF to BMP reduce quality?
No. BMP is lossless, so the image is saved exactly as it is. Detail already lost in AVIF can't be restored.
Does BMP keep transparency?
BMP doesn't support transparency, so transparent areas are filled with a background color you can choose.
Why is my BMP file bigger than the AVIF?
AVIF uses stronger compression than BMP. The picture stays the same, but BMP needs more bytes to store it.
