Everything happens in this browser, so your images never leave your computer. PNGs are compressed with libimagequant and OxiPNG, JPGs with Google's JPEGli, and every result is scored with SSIMULACRA 2, the quality metric from Cloudinary and JPEG XL.
This free WebP to JPG converter turns WebP images into JPGs that open in any app, email or upload form.
It scores each result and uploads nothing.
Here's what a WebP to JPG converter does, when to use one, and how this one did against CloudConvert.
What is a WebP to JPG converter?
A WebP to JPG converter turns a WebP image into a JPG file: the same picture, in a format that opens somewhere else.
This one works in your browser, and gives every file a score that shows how close it looks to the original.
What is a WebP file?
WebP is Google's image format for websites. Browsers show it, but many apps, printers and upload forms only take JPG or PNG.
JPG is the format everything opens. It has no transparency, so see-through parts get a background color you pick.
Compared with CloudConvert
I converted the same WebP files here and with CloudConvert, at each one's default settings. Then I scored every result against its original:
- Original
- 37 KB
- CloudConvert
- 91 KB, score 88.8
- This converter
- 44 KB, score 83.8
- Original
- 44 KB
- CloudConvert
- 112 KB, score 88.8
- This converter
- 68 KB, score 84.7
- Original
- 72 KB
- CloudConvert
- 51 KB, score 90.4
- This converter
- 25 KB, score 87.8
This converter's JPGs were 40% to 52% smaller than CloudConvert's, and scored 2.6 to 5.0 points lower. Every one scored over 80, the same side by side at 100%.
How I tested
I tested on September 29, 2026. I saved 3 pictures as WebP at quality 85, a common setting: Kodak test photo 23, a Mac screenshot and the PNG transparency demonstration from Wikimedia Commons.
The score is SSIMULACRA 2, a metric from Cloudinary that compares two pictures the way your eye does:
| Score | What it means |
|---|---|
| 90 and up | Looks identical: no difference even flicking between them at 100% |
| 80 to 90 | Same side by side at 100% |
| 70 to 80 | High quality: hard to notice without comparing |
| 50 to 70 | Medium quality: you can see it up close |
| Under 50 | Visible loss |
Who is the WebP to JPG converter for?
It's for anyone whose app or upload form won't take WebP:
- Pinterest image downloader – people saving images to use as references
- Twitter photo downloader – people saving images from X
- Image resizer – anyone fitting the JPG to a size
- Compress image to 100 KB – anyone fitting an upload form's limit
It works in your browser, and the new file leaves out hidden details like the camera and where a photo was taken.
