Quick Answer: How to Convert AVIF to BMP
AVIF is AV1-based image format — the newest mainstream compression champion. BMP is Windows Bitmap — the raw, uncomplicated pixel grid. Converting between them re-encodes the media with BMP's compression model, so output quality depends on the settings you pick in the converter. Run it free at practicalwebtools.com/convert/image/avif-to-bmp: drop in your AVIF, adjust settings if you like, and download the BMP — no signup, no upload, everything stays on your device.
How to Convert AVIF to BMP Online
- 1
Add your AVIF file
Drag and drop it into the converter, or click to browse. AVIF files up to the size limit are accepted, and nothing is uploaded — processing runs locally in your browser.
- 2
Set BMP options
Pick your quality: the converter exposes the settings that matter for BMP. Higher bitrates preserve more of the AVIF's detail at larger file sizes.
- 3
Download the BMP
Conversion runs on your device. When it completes, download the BMP file — repeat for as many files as you need, free and unlimited.
Key Facts About AVIF to BMP Conversion
- AVIF: AOMedia (Google, Netflix, Apple, etc.), 2019, lossy and lossless — roughly 50% smaller than JPEG at equal quality.
- BMP: Microsoft/IBM, Windows 1.0 era (1985), usually none — 24-bit BMP is width×height×3 bytes.
- AVIF strength: dramatically smaller than JPEG/WebP.
- BMP strength: trivial to read and write — no decoder needed.
- AVIF limitation to know: encoding is slow (AV1 complexity).
- BMP limitation to know: huge files.
AVIF vs BMP: Format Comparison
What is AVIF?
AVIF is a modern image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining high quality.
- File extension: .avif
- Developed by: Alliance for Open Media
- Best for: Next-generation web images, small file sizes
What is BMP?
BMP is an uncompressed raster image format. It produces large file sizes but maintains exact pixel data without any compression artifacts.
- File extension: .bmp, .dib
- Developed by: Microsoft
- Best for: Windows icons, exact pixel data preservation
Why Convert AVIF to BMP?
- BMP is perfect for windows icons, exact pixel data preservation
- Web browsers load BMP images faster
- BMP supports features AVIF doesn't (transparency, animation)
- Converting to BMP reduces file size for web use
- BMP is required by specific applications or platforms
Frequently Asked Questions
Will converting AVIF to BMP lose quality?
It depends on the formats: AVIF is lossy and lossless — roughly 50% smaller than JPEG at equal quality and BMP is usually none — 24-bit BMP is width×height×3 bytes. Any step from a lossless source into BMP keeps everything; any lossy step re-encodes and discards some data.
Are my files uploaded anywhere during AVIF → BMP conversion?
No. This converter runs on WebAssembly inside your browser — your AVIF file is read from disk, processed by your device's CPU, and the BMP is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
What BMP settings should I choose?
For legacy Windows assets, start with the converter's default preset — it's tuned for the common case. If you need smaller files, step quality down gradually and listen or look at the result before batch-converting everything.
Why is my BMP file larger/smaller than the AVIF original?
BMP is usually none — 24-bit BMP is width×height×3 bytes, while AVIF is lossy and lossless — roughly 50% smaller than JPEG at equal quality. File size follows from that: moving to a less aggressive or lossless target grows the file; moving to efficient lossy compression shrinks it. a 1920×1080 24-bit BMP is exactly 6,220,800 bytes of pixel data — you can compute a BMP's size on paper, which is why it's still used in teaching and embedded systems
