About AVIF To BMP Converter Online
AVIF (AV1 Image File Format) is a next-generation format based on the AV1 video codec. It delivers exceptional compression — often 50% smaller than JPEG — while supporting transparency, HDR, and wide color gamut.
Converting to BMP produces an uncompressed image file with no quality loss, ideal for use in Windows applications, older design software, or any pipeline that requires uncompressed pixel data.
This tool converts your AVIF images to BMP directly in the browser. Upload your file, choose a quality preset if available, and download the converted result instantly.

How to convert AVIF to BMP
Upload your AVIF file
Click the upload area or drag an AVIF image onto it. The file is read locally — nothing is sent to a server before conversion begins.
Convert
Press the Convert button. Sharp decodes the AVIF and re-encodes it as a 24-bit BMP. No quality setting is needed; BMP is lossless and uncompressed.
Download the BMP
When the output appears, click Download to save the .bmp file. BMP files are large because they store raw pixel data — expect the output to be much bigger than the source AVIF.
When to use BMP output
BMP is best for legacy Windows workflows, old image-processing pipelines, or anywhere that requires an uncompressed raster with no metadata overhead. For general use, PNG gives the same lossless quality at a fraction of the size.
