Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many BMP files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting BMP to AVIF reduce quality?
AVIF is lossy, so some fine detail is removed to make the file smaller. At the default quality it's hard to see; raise the Quality slider to keep more.
Which browsers does the BMP to AVIF converter work in?
It works in the latest Safari, Chrome and Edge, on computers and phones.
