Why convert BMP to AVIF?
Both are modern web formats, so this is usually about making a page load faster.
AVIF files are usually a good deal smaller than BMP, so this is a common way to save space.
BMP keeps every pixel exactly, while AVIF throws some detail away to save space. Use the quality slider to decide how much.
About the two formats
BMP: A plain Windows format with no compression. Files are big, but even very old programs can open them.
AVIF: The newest web format. It makes the smallest files of all, and every modern browser can show it.
The whole conversion happens in your browser. Your file is unpacked into raw pixels and saved again as AVIF. Nothing is sent to any server.
Common questions
Is the BMP to AVIF converter free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The BMP to AVIF converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Does converting BMP to AVIF lose quality?
A little, because AVIF saves space by throwing away detail the eye is least likely to miss, while BMP keeps every pixel exactly. At the default quality of 90 most people can't tell the two apart on a photo. Flat colour, sharp edges and text suffer the most, so lower the quality slider only while you're watching the preview.
Will the AVIF file be smaller than the BMP?
Usually much smaller. AVIF compresses far harder than BMP, and it's common to see a file drop to a fraction of what it was with no visible difference. How much you save depends on the picture, since photographs compress better than screenshots and line art.
Does converting BMP to AVIF keep the date and location from the original?
No. The image is rebuilt pixel by pixel, so the camera model, the date and any GPS location in the original aren't carried into the AVIF file. That cuts both ways: it strips information you may not want to share, and it loses information you may have wanted to keep. Check the original with the metadata viewer first if it matters.
