Is WEBP supported by all browsers?

Yes for any modern browser. Chrome has supported WEBP since 2010, Firefox since 2019, Safari since 2020 (macOS Big Sur and iOS 14), and Edge since 2018. Unless you need to support Internet Explorer 11 or very old Android versions, WEBP works everywhere your audience actually uses.

Will the quality drop?

At the default quality of 85, the perceptual difference between a JPG and its WEBP counterpart on photographs is imperceptible. WEBP compression is tuned to preserve details slightly better than JPG at equivalent file sizes, so you may even see sharper results at the same quality setting.

How much smaller will the WEBP be?

Typically 25 to 35 percent smaller than the source JPG. On very compressible content like portraits or gradients, reductions of 40 to 50 percent are common. On already-optimized JPGs near quality 60, the gap narrows.

Does WEBP support transparency?

Yes. WEBP carries a full alpha channel just like PNG. Since the source JPG has no transparency, the output WEBP will be fully opaque, but the format itself can carry transparency when the input provides it.

Is my file uploaded anywhere?

No. The conversion runs 100 percent client-side. Your JPG is read by your browser, processed via the Canvas API, and the WEBP is generated locally. No file is ever sent, stored, or logged.

Convert JPG to WEBP — smaller photos, same quality

Drop a JPG below and get a WEBP typically 25 to 35 percent smaller, with no visible quality loss. Everything runs in your browser.

WEBP is Google’s modern image format, designed to replace JPG on the web. At equivalent visual quality, a WEBP photo is typically 25 to 35 percent smaller than the same image saved as JPG. On a page loading a dozen photos above the fold, that difference translates directly into faster Largest Contentful Paint, better Core Web Vitals, and better Google rankings. WEBP has been supported in every major browser since 2020 — Chrome, Firefox, Safari, Edge, Opera — so you can ship WEBP images confidently for any modern audience.

This converter runs fully client-side using the HTML5 Canvas API, which encodes WEBP natively in all supporting browsers. Your image never leaves your device. Drop a JPG, pick a quality level (the default of 85 is already a good balance), and download the WEBP. No subscription, no account, no watermark, no server ever involved in the transformation.

How to convert JPG to WEBP in 4 steps

1

Select your JPG

Drag it onto the dropzone or click to browse. Any file your device can open is accepted.
2

Choose a quality level

85 is a solid default. Raise it for higher fidelity, lower it for a smaller file. WEBP tends to preserve detail slightly better than JPG at the same setting.
3

Let your browser re-encode

The Canvas API reads the JPG and produces a WEBP locally. Most photos finish in well under a second.
4

Download the result

Compare original and converted sizes in the result panel, then click download to save your WEBP.

JPG vs WEBP: why WEBP wins on the web

JPG was designed in 1992 and relies on a discrete cosine transform compression scheme that was cutting edge at the time. WEBP, released by Google in 2010 and steadily improved since, uses a more modern scheme derived from VP8 video intra-frame coding. In practice this means WEBP achieves the same perceived quality with 25 to 35 percent fewer bytes on photographs, and even larger gains on graphics with flat color regions. WEBP also supports both lossy and lossless modes, plus transparency through an alpha channel — things JPG cannot do. The only downside: a handful of legacy image viewers and very old CMS platforms still do not recognize WEBP. For the modern web, though, WEBP is strictly better.

When should you convert JPG to WEBP?

Optimizing hero images for Core Web Vitals

Replacing the JPG hero of a landing page with WEBP can shave a full second off LCP on a 3G connection. It is one of the easiest wins in web performance.

Shrinking a photo gallery before uploading

A 30 percent reduction in total gallery weight means 30 percent less CDN bandwidth billed and noticeably faster scrolling through images.

Cutting email newsletter weight

WEBP is supported by most modern email clients and helps newsletters load faster on mobile inboxes.

Preparing assets for a Progressive Web App

WEBP combines smaller size with alpha support, perfect for app icons, UI assets, and image-heavy PWA screens.
