Overview
What this tool does
Convert JPG, PNG, GIF, and BMP images to WebP, a modern format that's typically 25-35% smaller at the same visual quality. Batch convert several images at once, adjust the quality, and see exactly how much space you save. Everything runs in your browser, so images are never uploaded.
Smaller, faster
Why WebP?
WebP was created by Google specifically to make web images smaller. It compresses more efficiently than the older formats:
| Compared to | Typical savings | |
|---|---|---|
| WebP (lossy) vs JPG | photos | 25-35% smaller |
| WebP (lossless) vs PNG | graphics, logos | 20-30% smaller |
| Transparency support | like PNG | yes, with alpha |
Smaller images mean faster page loads, less bandwidth, and better Core Web Vitals — all of which help user experience and SEO.
Size vs clarity
Choosing a quality level
- 90-100%: near-lossless, best for hero images and detailed graphics
- 80-90%: the sweet spot — visually indistinguishable from the original for most photos, with big savings
- 60-80%: noticeably smaller, fine for thumbnails and less critical images
- Below 60%: visible artifacts; use only when size matters more than quality
Start at 85%
Is it safe to use?
Browser support
As of 2026, WebP is supported by every major browser — Chrome, Firefox, Safari, and Edge — and most apps and CMS platforms. It's safe to use across the modern web. For the rare case of very old software, you can serve a JPG or PNG fallback using the HTML picture element.

Common questions
How do I convert PNG to WebP?
Drag your PNG into the tool, pick a quality, and download the WebP. PNGs with transparency keep their transparency in WebP.
Does WebP support transparency?
Yes. WebP has an alpha channel like PNG, so logos and icons with transparent backgrounds convert correctly and stay transparent.
Is WebP better than JPG?
For the web, generally yes — WebP produces smaller files at the same quality and also supports transparency and animation. JPG is still useful for maximum compatibility with old software and some print workflows.
Can I convert animated GIFs to WebP?
This tool converts the first frame of a GIF to a still WebP. Animated WebP (which can replace GIF at a fraction of the size) needs a specialized animated encoder.
Will converting reduce quality?
At high quality settings (85%+), the difference is usually invisible while the file is much smaller. Lower settings trade quality for size. You control the balance with the slider.
