Convert AVIF to BMP Online
Encoding is extremely slow (up to 10x slower than WebP) and browser support, while growing, is still not 100%. Converting to BMP gives you a key advantage: zero processing overhead — raw pixel data can be read directly into memory without a decompression step. BMP is best for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access.
Why Convert AVIF to BMP?
Encoding is extremely slow (up to 10x slower than WebP) and browser support, while growing, is still not 100% — converting to BMP overcomes this by providing zero processing overhead — raw pixel data can be read directly into memory without a decompression step
BMP is the right choice when you need to: intermediate format for image processing pipelines that need raw pixel access
Gain broader compatibility — BMP works with Windows (native), macOS, Linux, all image editors; rarely used on the web
Your AVIF files were created for storing hdr photography with wide color gamut for professional workflows, but now you need a format suited to different workflows
AVIF vs BMP — Format Comparison
AV1 Image File Format (.avif)
Windows Bitmap (.bmp)
How to Convert AVIF to BMP
Upload your AVIF file
Drag your .avif file onto the upload area or click to browse. We accept AVIF files up to 50 MB.
Choose BMP as output format
Select .bmp (Windows Bitmap) from the format list. BMP uses lossless encoding, so your output quality matches the source.
Convert and download
Click Convert and wait for processing. Your BMP file will be ready to download in seconds. The result is optimized for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access.
Frequently Asked Questions
Is the AVIF to BMP conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. Uncompressed pixel-perfect quality; supports 1-bit through 32-bit color depth.
How large will my BMP file be compared to the original AVIF?
expand_more
AVIF files are typically 5 KB – 8 MB, while BMP files are typically 1 MB – 100 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted BMP file?
expand_more
BMP is compatible with: Windows (native), macOS, Linux, all image editors; rarely used on the web.
What is the maximum file size I can convert?
expand_more
PureConverter accepts AVIF files up to 50 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between AVIF and BMP?
expand_more
AVIF (AV1 Image File Format) is best for next-generation web images with the highest compression efficiency available today. BMP (Windows Bitmap) is best for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access. Key tradeoff: AVIF's advantage is achieves 50% smaller files than jpeg and 20% smaller than webp at equivalent quality, with hdr and wide color gamut support, while BMP's advantage is zero processing overhead — raw pixel data can be read directly into memory without a decompression step.
Pro Tips for AVIF to BMP Conversion
BMP preserves full quality, so your output file will be as good as the AVIF source — no need to worry about compression artifacts
If your AVIF file has transparency, make sure BMP supports it — BMP supports transparency
BMP works especially well for: screen capture output from older windows tools and apis
Did you know? BMP files store pixel rows bottom-to-top by default (origin at bottom-left), a convention inherited from OS/2 that confused generations of graphics programmers.
