Questions about AVIF to BMP
- Does converting AVIF to BMP improve the image quality?
- No. AVIF already threw detail away when it was saved, and that detail does not come back. Writing the lossless BMP preserves the picture you have now, but the file is usually several times larger.
- What happens to transparency?
- It is lost. AVIF supports transparency and BMP does not, so transparent areas are filled with white. If the background colour matters, flatten the image onto a solid background before converting.
- Is there a file size limit?
- No limit that we impose. The only ceiling is your device's memory, so a very large photo or a long recording may take a few seconds.
- Are my files uploaded anywhere?
- No. The conversion runs inside this browser tab, so the file never leaves your device — go offline once the page has loaded and keep converting.
