Why every saved image is suddenly .webp
Sites serve WebP because it's ~30% smaller than JPG, which makes pages faster. Your browser displays it fine — but the moment you save one and try to use it in an older app, a Word doc, a print shop, or an upload form, it gets rejected. Converting locally takes milliseconds because your browser already knows how to decode WebP natively — no server needed, which is why the sites that make you upload for this are wasting your time.
JPG or PNG?
JPG for photos — smaller files. PNG if the image has transparency (logos, stickers, screenshots of UI) — JPG would flatten transparent areas to white.
FAQ
Is there a file limit?
No. Drop a folder's worth. Auto-download zips a batch into one save.
What about animated WebP?
You'll get the first frame as an image. A proper WebP→GIF/MP4 tool is coming.
Quality loss?
One decode → one encode at high quality. For photos the difference is invisible; choose PNG for pixel-exact graphics.
