How it works
Upload your JPG files
Drop in one JPEG or a whole batch — dimensions and file size show up instantly.
Set quality & size
Pick the WebP quality level and optionally resize — the default 85% is a great starting point.
Download
Grab a single WebP directly, or select multiple and download them together as a ZIP.
Same look, smaller file
Batch conversion
Add any number of .jpg or .jpeg files and convert them all in one pass.
25–35% smaller on average
WebP consistently beats JPEG on file size at equivalent visual quality.
Adjustable quality
Balance file size and image quality with a simple slider, applied to every file.
Universal browser support
JPG is decoded by every browser, so you never hit a "can't read this file" problem on the input side.
Optional resizing
Keep the original resolution, scale down by a percentage, or cap output to a maximum width.
Runs entirely on-device
Every file is read and converted locally in your browser. Nothing is ever uploaded or stored anywhere.
Frequently asked questions
Why convert JPG to WebP?
WebP typically produces a 25–35% smaller file than JPEG at the same visual quality, which means faster page loads and less bandwidth — with no change to the image's appearance.
Will converting JPG to WebP reduce quality?
Both formats use lossy compression, so there is a re-encode step, but at quality settings of 80% and above the visual difference is negligible. You can preview each result before downloading.
Can I convert multiple JPG files at once?
Yes. Add as many .jpg or .jpeg files as you like, convert them together, and download each WebP individually or grab them all at once as a ZIP.
Does WebP support transparency like PNG?
WebP does support transparency, but a JPG source image has no alpha channel to carry over, so the output WebP will also be opaque — just like the original JPG.
Will this work in any browser?
Most current browsers can encode WebP, but a few older or less common ones can't. If a file can't be converted, it will be flagged so you know to try a different browser.
Is my file uploaded to a server?
No. Every JPG file is read and converted locally in your browser. Nothing is ever uploaded, transmitted, or stored anywhere.
