Convert JPG to WebP
Convert a JPG to WebP in your browser. WebP typically delivers files 25-40% smaller than JPG at the same visual quality — a noticeable win for websites, uploads, and storage. Every modern browser supports it.
-
Stays on your device
Your image is read into your browser tab, converted with canvas, and handed to your downloads folder. No upload, no server, no log. The file never touches our infrastructure.
-
Phone photos work correctly
iPhone and Android JPGs encode rotation in EXIF metadata; we read it and bake the rotation into the converted file so the output looks the right way up. No more sideways photos.
-
JPG → WebP specifics
WebP uses newer compression that's better than JPG at preserving quality per byte. On photos, expect significant size savings with no perceptible quality difference.
How it works
- 1
Drop your JPG
Drag the file onto the box above, or click to browse. We read it locally — no upload.
- 2
Pick a quality (or stick with 90%)
WebP is a lossy format with a quality knob. 90% looks indistinguishable from the original on screen and is a great default; drop lower for smaller files if you need to.
- 3
Click and save
The converted file lands in your downloads folder with the right extension and a clean, sanitized filename.
Frequently asked questions
Does my image ever leave my device?
No. The conversion runs entirely in your browser using HTML canvas. There's no upload, no server, no log. Open DevTools while it runs and watch the Network tab — you'll see zero traffic carrying your image.
Is there a file size limit?
No limit set by us. The real ceiling is your device's memory and the browser's canvas size limits. Phones can typically handle photos up to about 50 megapixels; desktops can go bigger. Very large images may take a few seconds to encode.
Will the file be smaller after conversion?
It depends on the source and target. Generally: PNG → JPG and PNG → WebP produce much smaller files. JPG → WebP is also smaller. JPG → PNG and WebP → PNG produce larger files (PNG is lossless and tends to be bigger). The result panel shows you the exact before/after sizes.
Does this work on mobile?
Yes. Tap the drop zone to open the photo picker; tap save when done. On phones, the result lands in your Photos or Files app depending on your OS.
What about my original file?
Untouched. The converted file is a separate copy delivered as a download. Your original on disk stays exactly as it was.
How much smaller will the WebP be?
Photos typically end up 25-40% smaller than the source JPG at the same visual quality. The exact savings depend on the photo's content — busy detail-rich images compress less than smooth gradients or large flat areas.
Will the quality look the same?
At our default 90% quality setting, the visual difference is invisible to the naked eye on most photos. WebP and JPG are both lossy formats with different compression strategies — WebP's strategy is just newer and more efficient.
Should I always convert JPG to WebP?
If the WebP is for web display, yes — faster page loads, less bandwidth, same look. If you're sending the file to someone who'll edit it in legacy software, JPG remains the safer choice. For sharing on platforms that haven't adopted WebP yet (some social networks, older email clients), stick with JPG.
