Why convert AVIF to BMP?
AVIF (Alliance for Open Media, 2019) is best for the smallest possible web files, and BMP is lossless, so every pixel is preserved exactly. Converting AVIF to BMP makes sense when you need raw uncompressed bitmaps, legacy software — universal support, very large files. Transparency is preserved.
AVIF export works in every browser — where the browser can't encode it, Under1MB uses its own encoder, which takes a few seconds longer.
Questions
Is BMP smaller than AVIF?+
BMP files are typically very large where AVIF files are smallest, so in most cases yes. The result depends on the image.
Do my files get uploaded during the conversion?+
No. The AVIF is decoded and re-encoded by your own browser. Open your Network tab and watch it stay empty.
Can I convert several AVIF files at once?+
Yes. Drop a whole batch, convert them together and download the results as a single ZIP.
Is there a file size or daily limit?+
No limits and no account. The only real ceiling is your device's memory, since everything runs locally.
What happens to EXIF and GPS data?+
It's removed. Writing a fresh BMP drops camera, date and location metadata, which is usually what you want before sharing.
Does this cost anything?+
No. There is no server bill to pass on, so converting AVIF to BMP is free and always will be.
