When to use this tool

WebP is the recommended format for the modern web. It supports transparency, animation, and produces smaller files than PNG and JPG at equivalent quality. All major browsers support it; older systems sometimes need a fallback.

Step by step

Drop PNG (or JPG) files.
Pick a WebP quality. 0.85 is a sensible default.
Click Convert. Output preserves alpha if the source had it.

Use cases

Website asset pipeline. Replace PNG / JPG with WebP for faster page loads.
Mobile app assets. Smaller bundles.
Open-graph / social. Some platforms now accept WebP.
Archival re-encoding. Smaller storage footprint for image libraries.

FAQ

Will it preserve transparency?

Yes — WebP supports an alpha channel. Drop a PNG with transparent regions and the WebP will keep them.

Lossy vs. lossless?

Quality < 1 produces lossy WebP (smaller). Quality 1 produces near-lossless. The browser's built-in encoder doesn't expose a "true lossless" mode — for that use a desktop tool.

Does every browser open WebP?

All major modern browsers do (Chrome, Firefox, Safari 14+, Edge). Older Safari (< 14) does not. Test your audience.
