Convert JPG to WebP
Convert JPEG images to WebP format for 25-35% smaller files. Free, private, no upload.
Why Convert JPG to WebP?
WebP produces files 25-35% smaller than JPEG at the same visual quality. Switching your website images from JPEG to WebP can significantly improve page load speed and Core Web Vitals. All conversion happens in your browser — your files never leave your device.
How It Works
img.awajis decodes your JPEG using a WASM-compiled decoder, then re-encodes the raw pixels using Google's libwebp encoder — all running locally in your browser via WebAssembly.

Frequently asked questions
How much smaller is WebP than JPG?
Typically 25–35% smaller at the same visual quality, which speeds up page loads and saves bandwidth.
Does WebP reduce quality?
WebP’s lossy mode is very efficient — at a high quality setting the result is visually indistinguishable from the JPEG.
Is WebP widely supported?
Yes, all current browsers support it. For legacy compatibility, keep a JPG fallback.
Are images uploaded?
No — the conversion is done locally in your browser.
Will converting to WebP break older browsers?
Every browser released in the last several years reads WebP. For very old software, keep the original JPG as a fallback.
Is WebP good for page speed and SEO?
Yes — smaller images load faster, which improves Core Web Vitals and can help search rankings.
Does converting JPG to WebP improve quality?
It can’t restore detail the JPEG already lost, but at a high setting WebP preserves the existing quality while making the file smaller.
Can I convert many JPGs to WebP at once?
Yes — drop several images and download them together; each one is converted in your browser.
