Convert AVIF to BMP — For Specific Requirements

AVIF is a cutting-edge format with the best compression available, while BMP is one of the oldest and simplest formats with no compression at all. Converting between them is an unusual requirement, but it’s needed when legacy systems or embedded devices require uncompressed bitmap data from modern image sources.

Modern format with excellent compression. Limited browser support.

Apple's format. Excellent quality at small sizes.

Lossless format. Large files, ideal for print/archival.

256 colors max. Best for simple graphics.

Uncompressed bitmap. Very large files.

Vector trace. Best for logos and simple graphics. Not a pixel-perfect conversion.

Lossless format — files can be large

GIF is limited to 256 colors

Best for logos, icons, and line art. Photos produce stylized results.

BMP files are uncompressed and can be very large. Consider TIFF (LZW) or PNG for lossless with smaller file sizes.

Leave empty for all pages. Multi-page PDFs produce a ZIP.

Why Convert AVIF to BMP?

Very few use cases need BMP from AVIF. This conversion is for legacy embedded systems, industrial equipment, or specialized software that requires raw uncompressed bitmap data. For any other legacy format need, PNG or TIFF are better lossless options. JPG is better for size-constrained uses.

How to Convert AVIF to BMP

1

Upload your AVIF file by dragging it into the converter or clicking to browse. Files up to 50 MB are supported.

2

KoalaPic decodes the AVIF and saves the pixel data as an uncompressed 24-bit BMP file.

3

Download the BMP file. Both files are deleted after 1 hour.

Quality Note

No additional quality loss beyond what AVIF compression already applied. The BMP will be dramatically larger — 50 to 200 times larger than the AVIF source. Consider PNG or TIFF as better lossless alternatives unless BMP is specifically required.

Frequently Asked Questions

Only if a specific program demands BMP. It is close to the least efficient conversion available — from one of the most compact formats to the least — and PNG offers the same lossless result at a fraction of the size.

Typically 30 to 100 times. A 200 KB Full HD AVIF becomes a 6.2 MB BMP, because BMP stores every pixel uncompressed at width × height × 3 bytes regardless of content.

Usually not. Most BMP output is 24-bit with no alpha channel, so transparency is flattened. The rarer 32-bit BMP can hold alpha, but support for it across software is inconsistent — use PNG if transparency matters.

The BMP itself is lossless, so nothing is lost beyond what the AVIF already discarded during its own lossy encode. The BMP is a faithful, very large copy of the decoded AVIF.
