Questions about BMP to WEBP
- Does converting BMP to WEBP improve the image quality?
- No, and it can get slightly worse. BMP keeps every pixel; WEBP is a lossy format that discards some detail to make the file smaller.
- What happens to transparency?
- There is nothing to preserve: BMP has no transparency, so this does not come up.
- 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.
