WebP is excellent on the web and a nuisance everywhere else. You save an image, try to attach it to something, upload it to a form or open it in older software, and get told the file type is not supported. Converting to JPG is how you make it universally accepted again.
This tool re-encodes your WebP as a JPG inside your browser. The image is never uploaded.
How to convert WEBP to JPEG
- Add your WebP. Drag it onto the box above or click to browse.
- Set the quality. 82 is the default. Raise it if the image has text or sharp edges you need to keep clean.
- Download. The JPG downloads immediately and will open in essentially anything.
Why you ended up with a WebP at all
Almost nobody creates a WebP deliberately. You right-clicked an image on a website and saved it, and the site was serving WebP because it is smaller and faster, which is exactly what it is for. The format is doing its job; it just was not designed with your downstream software in mind.
That also explains why the file often refuses to attach or upload elsewhere: the systems rejecting it are frequently older than WebP's widespread adoption. Converting to JPG sidesteps the argument, at the cost of a somewhat larger file and any transparency the original had.
WebP or PNG as the destination
Choose JPG when the image is a photograph and you need it accepted everywhere. Choose PNG when the image has transparency you cannot lose, or when it is a screenshot, logo or diagram where JPG would smear the edges.
If you are only converting because one specific piece of software rejected the file, JPG is almost always the right answer: it is the format with the fewest arguments.
Frequently asked questions
- What happens to transparency?
- It is lost, and this is the one thing to watch. WebP supports an alpha channel and JPG does not, so every transparent pixel is composited onto white before encoding. A logo with a transparent background will come out sitting on a white rectangle. If you need the transparency, convert to PNG instead.
- Will the JPG be bigger than the WebP?
- Usually, yes, and often by 25 percent or more, because WebP simply compresses better. You are trading file size for compatibility, which is a fair trade when the alternative is a file the destination refuses to accept.
- Does converting lose quality?
- Some. The WebP was already lossy and JPG re-compresses it, so this is a second destructive pass. At quality 82 it is not something you will notice on a photograph.
- Is my image uploaded?
- No. Your browser decodes the WebP and encodes the JPG locally. Nothing goes to a server.
