AVIF vs BMP: Format Comparison
Key differences between the two formats
| Feature | AVIF | BMP |
|---|---|---|
| Compression | AV1-based lossy/lossless | Uncompressed (raw pixels) |
| File size | Very small (state-of-the-art) | Very large (raw data) |
| Color depth | Up to 12-bit, HDR | Up to 32-bit |
| Transparency | Full alpha channel | Limited (32-bit only) |
| Browser support | Chrome 85+, Firefox 93+, Safari 16.4+ | Universal |
| Best for | Modern web, bandwidth savings | Raw editing, Windows apps, printing |
| Platform | Cross-platform (modern) | Native to Windows |
When to Convert
Common scenarios where this conversion is useful
Image analysis and processing
Scientific tools and image processing software often require uncompressed BMP input for pixel-perfect analysis. Convert AVIF images to BMP for these workflows.
Windows application compatibility
Legacy Windows applications that don't recognize AVIF can open BMP files natively. Convert for compatibility with older software.
Print and engraving workflows
Professional printers and engraving machines sometimes require uncompressed input. BMP ensures no compression artifacts affect the printed output.
Extracting raw pixel data
When you need direct access to pixel values for programming or data analysis, BMP's uncompressed format provides the simplest raw pixel data structure.
How to Convert AVIF to BMP
-
1
Drop your AVIF file
Drag and drop your AVIF image into the converter area, or click browse to select it from your device.
-
2
Instant conversion
Your browser decodes the AVIF image and exports the raw pixel data as an uncompressed BMP bitmap. All decoded colors are preserved.
-
3
Download your BMP
Save the converted BMP file. The output contains uncompressed pixel data at the same dimensions as the original AVIF.
Frequently Asked Questions
BMP stores raw uncompressed pixel data, while AVIF uses state-of-the-art AV1 compression. A 100KB AVIF might become 5-10MB as BMP. This is expected — BMP trades file size for simplicity.
No. BMP is uncompressed, but it can only contain the pixel data that was decoded from the AVIF. Quality lost during AVIF compression cannot be recovered. The BMP preserves the decoded quality without adding new artifacts.
Standard 24-bit BMP does not support transparency. Transparent areas in your AVIF will be rendered with a white background. 32-bit BMP can store alpha, but compatibility varies.
You need Chrome 85+, Firefox 93+, Edge 121+, or Safari 16.4+. If your browser doesn't support AVIF, the conversion won't work. Try updating to the latest browser version.
BMP is needed for legacy Windows software, scientific image analysis, industrial printing, embedded systems, and any workflow that requires direct access to raw pixel values.
Yes. All decoding and conversion happens in your browser. Your AVIF files are never uploaded to any server, making this safe for confidential and sensitive images.
Yes. The converter runs in any modern browser that supports AVIF. The output BMP file can be opened on Windows, Mac, and Linux.
Yes, ChangeThisFile offers BMP to AVIF conversion. Re-encoding to AVIF will compress the data again, potentially at a different quality setting.
