Why Convert AVIF to BMP?
Converting AVIF to BMP produces an uncompressed version for legacy systems or applications that require the BMP format.
Common Use Cases
- Legacy system compatibility
- Embedded systems requiring BMP
- Raw pixel data extraction from AVIF
Source Format
AVIF
AV1 Image File Format
AVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining high visual quality, transparency, and animation support.
+ 50% smaller than JPEG at equivalent quality
+ Better compression than WebP
+ Supports transparency, animation, and HDR
- Slower encoding and decoding than JPEG or WebP
- Limited support in older browsers and software
Target Format
BMP
Bitmap Image File
BMP is an uncompressed raster image format native to Windows. It stores pixel data directly without compression, resulting in large file sizes but perfect quality.
+ No compression means zero quality loss
+ Simple format, easy to read and write programmatically
+ Native Windows support
- Extremely large file sizes
- No transparency support
Quality & Size Notes
BMP stores decoded pixels without compression. No further quality loss beyond original AVIF compression. Files will be extremely large compared to AVIF.
Frequently Asked Questions
How much larger will the BMP be?
Dramatically larger — often 50-100x the AVIF file size, since BMP stores raw pixel data without any compression.
Why would I need BMP from AVIF?
Only for legacy systems or embedded devices that specifically require BMP format.
Is transparency preserved?
No. BMP doesn't support transparency. Transparent areas will be filled with a white background.
