JPG to WebP Converter

Re-encode JPG photos as WebP to shave 25-35% off their size at the same visual quality, smaller uploads, faster pages, happier visitors.

Private by design: This tool runs entirely in your browser using its built-in image engine. Your files are not uploaded to a server, and nothing you convert is stored or logged. See how in-browser processing works.

How to convert JPG to WEBP

Drop your JPG files onto the upload area, or click it to browse.
Pick a quality level, 85-90% usually matches the original JPG visually while still saving real space.
Click Convert, then download each WebP or everything as a ZIP.

How much smaller, really?

For typical photos, WebP at the same visual quality comes out 25-35% smaller than JPG. On a single photo that's nice; across a product gallery or image-heavy page it compounds into meaningfully faster loads and better Core Web Vitals scores.

Picking a quality level

The default 87% matches the original JPG visually for almost all photos. Going above ~92% grows the file quickly for imperceptible gains; going below ~75% starts to soften fine detail. If you're optimizing a whole site, pick one setting, spot-check a few images, and batch the rest.

When JPG still wins

Print services, older software, and maximum-compatibility situations (email attachments, embedded documents) still favor JPG. Since both formats are lossy, keep your originals: converting back and forth loses a little each time. The full comparison is in our JPG vs WebP guide.

Good to know

WebP's encoder is simply more efficient than JPG's, same perceived quality, fewer bytes.
Converting between two lossy formats re-encodes the image; keep your original JPGs if you might need them again.
Every modern browser displays WebP, and this tool uses your browser's own encoder to create it.

Frequently asked questions

How much smaller is WebP than JPG?

For typical photos, expect files around 25-35% smaller at equivalent visual quality. Savings vary with the image content and the quality setting you choose.

Does converting JPG to WebP lose quality?

Both formats are lossy, so re-encoding discards a little more information. At 85-90% quality the change is generally invisible, but keep your originals for archival editing.

Where is WebP a good choice?

Websites, web apps, and anywhere download size matters. If you're sending photos to print services or older software, JPG remains the safer bet.

Are my photos uploaded to a server?

No. Everything happens in your browser: your photos never leave your device.

Should I keep my original JPGs?

Yes. JPG-to-WebP is a lossy-to-lossy conversion, each re-encode discards a little information. Treat WebP as the delivery format and your JPGs as the source.

Can WebP have a transparent background?

WebP supports transparency, but your source JPG doesn't have any, so the output won't either. Transparency workflows start from PNG.

Will the WebP work everywhere my JPG did?

In browsers, yes. In email clients, older office software, and print services, not always: check the destination before switching wholesale.
