How do I convert an image to WebP?

Drop one or more images, pick a quality (or toggle Lossless), and click Convert. The WebP files are ready to download in seconds.

WebP files are smaller than JPG or PNG at the same visual quality, which means faster page loads and lower bandwidth costs. They also support transparency, like PNG.

Is WebP supported on all browsers?

Yes — every modern browser supports WebP (Chrome, Firefox, Safari, Edge). Only browsers older than ~2020 lack support.

How much smaller will WebP be?

Typically 25–35% smaller at quality 80 versus an equivalent JPG, and around 50% smaller than a PNG. Photos see the biggest savings.

Will transparency be preserved?

Yes. WebP supports an alpha channel, so transparent PNGs become transparent WebPs.

Lossless or lossy — which is better?

Lossy at quality 80 is best for photos and screenshots. Lossless mode (where the browser supports it) is best for app assets, icons, or anything where you can't afford visible compression.

Can I batch-convert images to WebP?

Yes. Drop a folder and we convert them all with the same settings, downloadable individually or as a ZIP.

Are my files uploaded?

No. Conversion runs in your browser, so your images stay on your device.

Is the WebP converter free?

Yes — no signup, no watermark, no quality cap.

Does it work on mobile?

Yes. The tool runs in mobile Safari and Chrome on phones and tablets.

Good to know

WebP exists to make web images smaller without a visible drop in quality — typically 25–35% lighter than the same photo as a JPG. Across an image-heavy page that adds up to faster loads and less mobile data, which is why every modern browser now supports it. If you're deciding whether to switch your photos over, our JPG vs WebP comparison lays out when it's worth it and when plain JPG is still the safer bet.

WebP isn't the only modern format worth knowing about; AVIF squeezes files even smaller at the cost of slower encoding, as our WebP vs AVIF comparison explains. Whichever you choose, conversion here happens entirely in your browser — and if you only need to shrink an image without changing its format, try Compress Image instead.
