Convert AVIF to BMP
Updated Jul 2026
AVIF is a compressed format made for fast-loading web images, and BMP is an old, uncompressed Windows format that some legacy software still expects. To convert AVIF to BMP, open the file in a converter and export it as BMP. Doing this on your own computer means the image never has to be uploaded anywhere first.

Convert AVIF to BMP on your own computer. Nothing uploads.
How to convert AVIF to BMP
- Open Morphjet and drag in the AVIF file or a whole folder of them.
- Choose BMP as the output format.
- Convert. The BMP files are written next to your originals, and nothing leaves your machine.
AVIF vs BMP: what actually changes
| AVIF | BMP | |
|---|---|---|
| File size | Small, heavily compressed | Large, stored uncompressed |
| Quality | Very good, with some compression applied | Lossless once converted, pixels are stored exactly as decoded |
| Opens everywhere | No, needs a fairly recent browser or app | Yes, readable by nearly any program on Windows, even very old ones |
| Transparency | Yes | Not in practice, most software ignores it |
| Editing support | Limited in older image editors | Universal, the simplest format for editors to read and write |
When to convert, and when not to
Convert AVIF to BMP when you need the image for older Windows software, a legacy workflow, or a tool that specifically requires an uncompressed bitmap and won't open AVIF at all.
Keep the AVIF if the image is headed back to the web or staying on a modern device, since BMP files are many times larger with no real benefit for online use.
Why not just use an online converter?
AVIF files often start as screenshots, photos, or graphics you'd rather not hand to a stranger's server just to change the format. An online converter uploads the file, converts it somewhere else, and sends it back. Converting on your own computer means the image stays on your machine the whole time, even with the wifi off.
Questions
Does converting AVIF to BMP lose quality?
No further quality is lost in the conversion itself. BMP stores pixels exactly as they're decoded, so whatever quality the AVIF already had is preserved. Any compression artifacts came from the original AVIF encoding, not from converting to BMP.
Why is the BMP so much bigger than the AVIF?
AVIF is built to compress images tightly for the web, while BMP typically stores every pixel with no compression at all. It's common for a BMP to be ten times larger or more than the AVIF it came from.
Will the BMP keep transparency from the AVIF?
Usually not in any way that other software will honor. BMP has a technical option for an alpha channel, but most programs treat BMP as fully opaque, so transparent areas typically end up as a solid background color.
Can I convert AVIF to BMP without an internet connection?
Yes. A desktop app like Morphjet reads the AVIF and writes the BMP locally, so there's nothing to upload and no connection required.
Morphjet converts AVIF, BMP, and 1,800+ other formats, all on your machine. Launching this July.
