Why you ended up with a WebP
WebP is the image format many websites now serve, so a picture you saved from a page, a chat or a social post often arrives as .webp. It is efficient, typically 25–35% smaller than JPG at a similar look, and every modern browser can show it. The trouble starts when you try to use the file elsewhere: older versions of editing software, some print services, certain upload forms and plenty of email and document tools do not recognise it. JPG is the format everything accepts.
Converting in your browser
- Drop the WebP file on this page. Nothing is uploaded.
- It is converted to a JPG you can open anywhere.
- If the next place you will use it has a size limit, switch on the size requirement and convert and compress in one step.
What to expect
- The JPG will usually be larger. WebP packs the same picture into fewer bytes, so the JPG version takes more. That is expected, not a sign that something went wrong.
- Transparent areas become white. WebP supports transparency and JPG does not. If a logo or cut-out has a transparent background, it will be filled with white. Keep the WebP or use PNG if you need to preserve it.
- Animated WebP becomes a still image. JPG cannot move, so only a single frame is kept.
- Quality is kept high. The conversion is a single, careful save at high quality. Do not convert back and forth: each lossy save loses a little more.
Keeping an original
If the picture is yours, keep the original WebP as well as the JPG. It is smaller, and you can always make a JPG from it again; going the other way never recovers what a JPG has discarded. If it is a website image you are saving for your own use, remember that images belong to their owners: use them in line with the site’s terms.
To shrink the result for an upload, see compress to 200 KB or 100 KB. For a full comparison of the three formats, read JPG vs PNG vs WebP.
