Questions about AVIF to WEBP
- Does converting AVIF to WEBP improve the image quality?
- No. Both formats are lossy, so every re-save shaves off a little more detail. Convert once from the original wherever you can.
- What happens to transparency?
- It survives. Both AVIF and WEBP carry an alpha channel, so transparent areas stay transparent.
- 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.
