Why images from the web won't open in your apps
Websites increasingly serve images as WebP or AVIF because they are 30–50% smaller than JPG at the same quality — pages load faster and bandwidth bills drop. Browsers handle them fine. The rest of the world often doesn't: older versions of Photoshop won't open WebP without plugins, many photo viewers and office apps reject AVIF outright, and plenty of upload forms only whitelist JPG and PNG.
So the moment you save a picture from a website and try to actually use it, you hit a wall. This converter fixes that in seconds: your browser already knows how to decode WebP and AVIF, and this tool uses that built-in decoder to re-encode the image as a standard JPG or PNG. Because the decoding happens in the same browser you saved the file with, compatibility is guaranteed — if you can see the image, you can convert it.
Choose PNG when the image has transparency (logos, stickers, cut-outs) — JPG doesn't support it, and transparent areas would otherwise be flattened onto white. For photos, JPG at 90% quality is visually identical to the source and much smaller than PNG.
