Convert WebP to JPG
You saved a picture from a website and got a file half your programs refuse to open. Drop it here and take back an ordinary JPG. The conversion happens on your own device — the image is never sent anywhere.
Files never leave your browser
Why the web handed you a file you cannot use
WebP is Google's image format. It was built to make web pages load faster, and at that job it is genuinely good — the same photograph usually lands 25–35% smaller than the equivalent JPG.
The catch is that it was designed to be displayed by browsers, not to be handed to people. When you right-click a picture in Chrome or Edge and choose Save image as…, you get whatever the website served — and a great many sites now serve WebP to everybody. So the file on your desktop is in a format you never chose and possibly cannot open.
Nothing is broken. The picture is intact. It is simply wearing a coat that your older software does not recognise.
What actually changes when you convert
Worth knowing before you press the button, because most converters do not say it.
WebP files are usually lossy — detail was already discarded when the website made them. JPG is also lossy. Converting one to the other means encoding a second time, and a second encoding can never put back what the first one removed.
In practice, at the quality this page uses, you will not see the difference on a photograph. Where you might see it is on sharp edges and flat colour — screenshots, diagrams, logos, text on a plain background. If your file is one of those, convert to PNG instead: it is bigger, but it is lossless, and the edges stay crisp.
The transparency trap almost nobody mentions
WebP can store transparency. JPG cannot — it has no concept of a see-through pixel.
So if your WebP has a transparent background — a logo, a sticker, a cut-out product photo — converting it to JPG will fill that transparency with solid colour. Most tools do this silently and hand you a logo sitting on a white box, which is exactly what you did not want.
If your image has transparency and you need to keep it, pick PNG in the box above. It is the only common format that keeps both the picture and the see-through parts. Choose JPG only when you know the background is solid anyway.
No upload, no limit, and you can check it yourself
Your file is read from your disk, decoded in your device's memory, and handed straight back as a download. It is not uploaded, not stored, and not seen by anyone — there is no server here doing the work, which is also why there is no daily cap, no sign-up and no watermark.
That is not just a claim. This page is served with a Content Security Policy containing connect-src 'self', which instructs your browser to refuse any connection to another address. Open your browser's network tab, convert a file, and watch that nothing leaves. Or load the page once, disconnect from the internet, and convert anyway — it still works.
You can drop a whole folder's worth at once. The limit is your device's memory, not a number we invented to sell you an upgrade.
