WebP Converter
Convert JPG or PNG images to modern WebP with adjustable quality, in your browser.
Convert images to WebP in your browser
This WebP converter re-encodes JPG and PNG images as WebP, a modern format that typically produces noticeably smaller files at the same visual quality — ideal for fast websites. The conversion is done on a canvas right on your device, so your file is never uploaded to a server.
Tune the quality, watch the saving
Drag the quality slider from 0.1 (smallest) to 1.0 (sharpest) to balance
size against detail; 0.8 is a sensible default. The tool shows the original and WebP sizes
so you can pick the sweet spot. Most current browsers can create WebP; if yours cannot, the tool tells
you and falls back to your original format.
How to use the WebP Converter
- Choose an image. Pick a JPG, PNG or other image from your device.
- Set the quality. Drag the slider between 0.1 and 1.0 to trade size against detail.
- Check the saving. Compare the original size with the new WebP size.
- Download. Save the .webp file — it is created instantly in your browser.
Frequently asked questions
Is my image uploaded to convert it?
No. The conversion runs entirely in your browser with the Canvas API; the file is never uploaded, stored or seen by any server.
Why convert to WebP?
WebP usually gives smaller files than JPG or PNG at similar quality, which makes web pages load faster and saves storage and bandwidth.
What if my browser cannot make WebP?
A few older browsers cannot encode WebP. The tool detects this, shows a note, and saves the image in its original format instead so you still get a file.
Does WebP support transparency?
Yes. Unlike JPEG, WebP keeps transparency from a PNG source, so logos and cut-outs stay clean.
