BMP is the uncompressed Windows bitmap format: simple and readable everywhere, but files are very large. AVIF gives the smallest files of any widely supported format at the same visual quality, which makes it great for fast websites.
AVIF encoding is slower than other formats, so large images take a few extra seconds. The AVIF is saved at quality 85, which keeps detail while cutting file size.
You can drop several BMP files at once and get a ZIP of AVIF files. Each file can be up to 20 MB; there's no daily limit and no signup, and uploads are deleted from our servers within 1 hour.
Drag BMP files onto the page or click to choose them. You can add several at once.
Conversion starts on its own — there are no settings to pick. Most files are ready in a few seconds.
A single file downloads as AVIF; several files come as one ZIP archive.
Use the AVIF right away: open it, share it or upload it wherever you need it.
Your uploads and results are deleted from our servers within 1 hour.
