What are AVIF and BMP files?
AVIF (.avif)
AVIF is a next-generation image format based on the AV1 video codec. It can be up to 50% smaller than JPG at the same quality, but many apps and upload forms still cannot open it.
BMP (.bmp)
BMP is an old uncompressed bitmap format from Microsoft Windows. It stores raw pixel data, so quality is perfect but files are very large.
Tips for the best BMP results
- BMP has no transparency, so transparent areas are filled with a background colour (white by default — you can change it).
- Bookmark this page or install the app to convert AVIF files offline next time.

Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
