JPG to WebP Converter

Three steps:

1. Drop your JPG files onto the area above, or click to select
2. Each file is decoded in your browser and re-encoded as WebP at the quality you pick — 92% by default
3. Click Save next to each result to download your WebP files

WebP produces files 25–35% smaller than JPG at the same perceived quality. For a website serving thousands of photos, that means substantial bandwidth savings and faster page loads.

WebP also supports transparency, which JPG cannot. If you ever need alpha (for overlays, cut-outs, etc.), WebP is a more flexible container than JPG.

WebP is supported by:

• Chrome and Edge — full support since 2014
• Firefox — full support since 2019
• Safari — full support since Safari 14 (September 2020)

That covers 96%+ of web users today. For the small remaining segment, serve JPG as a fallback using the <picture> element so older browsers get the JPG while modern browsers get the smaller WebP.

Like JPG, WebP is lossy by default. At 92% quality the visual difference is usually imperceptible, but some pixel data is removed. WebP also supports a lossless mode, but it produces files larger than JPG for photographs — use lossy WebP with high quality for photos, and lossless WebP only for screenshots and graphics.

Want to see the difference for yourself? Compare the original and the WebP in our image compare tool — pixel diff and perceptual score included.

For fine control over compression, try our image compressor.

JPG itself does not support animation — only the first frame would be converted. WebP can be animated but needs an animated source (GIF or animated WebP). For animated images, use our WebP to GIF tool or convert via gif.js.optimized.

Up to 50 JPG files in a single batch — converting in bulk is fine. Files are processed one by one inside your browser, and Save ZIP downloads every result as one archive.

No upload, so connection speed does not matter.

WebP is an image format Google introduced in 2010. It compresses photos 25–35% smaller than JPG at the same perceived quality, supports transparency and animation, and is supported by Chrome, Edge, Firefox, and Safari 14+ (September 2020).

Three honest ones: older browsers (Safari before 14, Internet Explorer) cannot display it, so keep a JPG fallback if you need to support them; it is lossy by default, like JPG; and animated WebP needs a dedicated tool to create.

Also note that “smaller” is typical, not guaranteed — re-encoding an already-compressed, low-quality JPG can produce a slightly larger file.

Yes. All conversion runs in your browser via the Canvas API. Your JPGs never leave your device and are not stored, logged, or transmitted anywhere. No account, no signup, no ads — and because the image is re-encoded from pixels, EXIF metadata such as GPS location is not carried into the output.
