Do you have a WEBP picture that a form, a printer or an app refuses, and it keeps asking for a JPG instead?
Don’t worry, you are not alone, and it is a thirty second fix. Add your WEBP files below, keep JPG selected, and press Convert. This WEBP to JPG converter runs in your browser, so nothing is uploaded.
Your pictures never leave this computer. They are converted in your browser. Nothing is uploaded.
Pictures are converted at their own size. Nothing is resized or cropped unless it is an SVG, which you can draw at any width.
The black background trap
This is the one thing worth knowing before you convert anything to JPG.
A WEBP can have see-through parts, like a logo with no background. A JPG cannot. So something has to fill those parts, and the obvious way of saving a JPG in a browser fills them with black. I tested this in Chrome before building the page: the see-through half of a test picture came back pure black.
That is how a transparent logo turns into a logo on a black box, and why a dark logo can disappear completely.
Here every picture is laid on white before it is saved, and you can pick any other colour in the Background box, for example to match the page the picture is going on. The result tells you which files had see-through parts, so nothing changes without you knowing.
What the quality slider does
JPG keeps a picture small by throwing away detail your eye is unlikely to notice. The slider decides how much. Think of it like folding a letter to fit an envelope: a couple of folds and nobody can tell, too many and the creases start to show.
It starts at 90, which is a good balance for photos. In my own test, a 66 KB WEBP photograph became a 70 KB JPG at 90, so you pay almost nothing in size for a file everything can open. Drop to 75 or 80 if you need it smaller. Go below 60 only if size matters more than looks.
Keep in mind that a JPG cannot be better than the WEBP it came from. Setting 100 makes a bigger file, not a sharper one.
When JPG is the wrong choice
JPG is built for photographs. On screenshots, text, logos and line drawings it leaves faint smudges around sharp edges, which you can see if you zoom in. For pictures like those, choose PNG in the Convert to box, or use the WEBP to PNG page, and the edges stay crisp.
Your photo’s hidden details are left behind
The JPG is drawn fresh from the picture’s pixels, so hidden details such as a camera model or GPS position are not copied into it. For a picture you are about to send to a stranger or post publicly, that is usually a good thing. If you need those details kept, this tool will not do it.
Where this stops, honestly
- Animated WEBP files become one still JPG of the first frame. A JPG cannot move.
- Quality cannot go up. Detail the WEBP threw away is gone for good.
- Very vivid photos from some newer phones are brought into ordinary screen colours.
- Dozens of huge photos at once can make an old phone slow, because everything happens on your own device.
Frequently asked questions
Is it free, and is there a limit?
It is free, with no sign up and no watermark. There is no file limit apart from what your device’s memory can hold.
Can I download everything at once?
Yes. When you convert more than one picture, a ZIP with all of them is offered under the list.
Why is my JPG bigger than the WEBP?
WEBP usually makes smaller files than JPG does, so a slightly bigger JPG is normal. In my own test it was 70 KB against 66 KB. If yours is much bigger, lower the quality slider a few steps.
