Questions about PNG to WEBP
- Does converting PNG to WEBP improve the image quality?
- No, and it can get slightly worse. PNG keeps every pixel; WEBP is a lossy format that discards some detail to make the file smaller.
- What happens to transparency?
- It survives. Both PNG 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.
