How WebP Converter works
How does the WebP conversion work?
It's the same canvas round-trip as the other converters: draw the source image onto a canvas, then call canvas.toBlob() with image/webp as the target MIME type and your quality value as the compression level. The tool defaults to converting into WebP unless the file you uploaded is already WebP, in which case it flips the default target to PNG.
What's the practical reason to convert to or from WebP?
WebP files are usually meaningfully smaller than an equivalent-quality JPG or PNG, which makes this a quick way to shrink images for a website; going the other direction is for when you've downloaded a WebP image but need a PNG or JPG for a tool or platform that doesn't accept WebP.
What if my browser can't actually produce WebP?
A handful of older browsers can decode WebP but can't encode it — when that happens, canvas.toBlob() silently returns a PNG blob instead of the WebP you asked for. The tool checks the returned blob's actual MIME type against what you requested and shows a warning banner so you know your download fell back to PNG rather than failing silently.
