WEBP to JPG

Almost everyone arriving here has hit a wall rather than made a choice. You right-clicked an image, saved it, and the thing you need to put it into will not accept a .webp. That list is long and stubborn: plenty of print services, older versions of Office, e-commerce product uploaders, digital photo frames, and a great deal of embedded and industrial software. JPG is the lowest common denominator of digital imaging and has been for three decades, so converting is usually faster than fighting whatever is rejecting the file. The second reason is size. If your WebP happens to be lossless — screenshots often are — it can actually be larger than a JPG of the same picture, and converting shrinks it substantially.

JPG has no alpha channel at all, so a transparent background cannot simply carry over. Something has to be painted underneath, and the default everywhere is white. That is fine on a white page and obvious on a dark one, which is why this tool lets you pick the fill colour instead of assuming. If the transparency actually matters to you, JPG is the wrong target — convert to PNG instead and keep it.

A lossy WebP has already discarded detail, and encoding to JPG discards a little more. In practice this is rarely visible at sensible quality settings, but it is a real effect and it compounds if you keep converting back and forth. Convert once, from the best source you have, and keep that result. If the image is going to be edited further, a lossless PNG makes a better intermediate.

JPG is a single-image format, so an animated WebP converts to its first frame. There is no way around that within JPG itself. If the animation is the point, convert to GIF instead.

WebP is Google's 2010 image format, and it is unusual in offering both lossy and lossless modes plus transparency in a single container. In practice it lands roughly 25–35% smaller than an equivalent-quality JPG, which is why it spread quickly across the web once Safari added support in 2020. Its weakness is outside the browser: plenty of desktop software, older phones and printing workflows still will not open a .webp file.

JPG (also written JPEG) has been the default photograph format since 1992. It uses lossy compression tuned for the way human vision works — discarding fine colour detail the eye barely registers — which is why a photo saved as JPG can be a tenth the size of the same image as PNG. The trade-off is that it has no transparency channel and that every re-save degrades the image slightly, so it suits finished photographs rather than working files.
