    Questions

    Why convert PNG to WebP?

    WebP files are much smaller than PNG for photos and detailed images, which makes websites load faster. Unlike JPG, WebP keeps transparency. Every current browser displays WebP.

    Is the WebP lossless?

    No. This tool makes lossy WebP, compressed at the quality you choose (90 by default). At high settings the difference is hard to see. Sharp text and pixel art can show slight softening; keep those as PNG.

    Does it work on iPhone and in Safari?

    Yes. Chrome, Edge and Firefox write WebP themselves. Safari, and every browser on iPhone and iPad, can’t, so a WebP encoder (libwebp, about 110 KB) downloads once and does it on your device.

    The WebP came out bigger than the PNG. Why?

    That can happen with simple graphics that PNG already compresses very well, like flat logos or screenshots with few colors. For those, the PNG is the better file.

    How many images can I do at once?

    Up to 20 files per batch, up to 50 MB each and 200 MB in total. Files are processed one after another; download each one as soon as it is ready, or all of them as a ZIP.

    Very large images are refused to keep your browser from running out of memory: above 100 megapixels on computers and 50 megapixels on phones and tablets. On iPhone and iPad, formats other than HEIC are limited to about 16 megapixels by Safari.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
