Turn BMP images into AVIF files right in your browser. AVIF usually makes the smallest files and keeps transparency. It takes longer to create.

Converting starts the moment you drop. Nothing is uploaded.
How it worksConversion re-encodes pixels: EXIF metadata and color profiles are not carried over, EXIF rotation is applied, and animated GIF, WebP, and AVIF inputs keep only their first frame (flagged on the result). Inputs are validated by their actual bytes, and every output is signature-checked before it counts as done.
