Why convert AVIF to BMP?
AVIF is lossy (cutting-edge web images when browser support is acceptable). BMP is lossless (Windows-centric legacy interchange). Converting AVIF to BMP remaps pixels into the target container in your browser. Transparency from AVIF will be flattened because BMP has no alpha channel.
What changes in the file
- Output is lossless BMP; existing AVIF artifacts are preserved, not repaired
- Alpha from AVIF is flattened onto an opaque background
- You can resize, adjust quality where relevant, and strip EXIF on export
- Conversion runs on this device — the file is not uploaded
How to convert AVIF to BMP
- Drop one or more AVIF files onto the converter (or pick them from disk).
- Confirm the output is set to BMP, then adjust quality, size, or metadata if needed.
- Download the converted BMP file — processing never left your browser.
About AVIF
AVIF is a next-generation image format based on the AV1 video codec. It typically yields smaller files than WebP or JPG at similar quality and supports transparency and high bit depth.
About BMP
BMP is an uncompressed Windows bitmap format. It is simple and widely readable on Windows, but files are large compared with modern compressed formats.
Common questions
Is this AVIF to BMP converter free?
Yes. Formatly converts AVIF to BMP in the browser at no charge and without an account.
Do you upload my AVIF files?
No. Decoding and encoding run locally with browser APIs and WebAssembly codecs when needed. Files stay on this device.
Will converting AVIF to BMP reduce quality?
BMP is lossless, so the export keeps the decoded pixels. If the source was already lossy (AVIF), prior compression artifacts remain.
