Shrink PNG graphics into modern WEBP files without losing transparency — ideal for logos, icons, and UI assets on the web.
PNG is a solid choice for graphics and transparency, but it's a lossless format, meaning its files stay comparatively large even after compression. WEBP was designed to solve exactly this: it keeps full alpha-channel transparency support like PNG, but with meaningfully smaller file sizes thanks to more efficient compression. For website assets like logos, icons, and UI graphics — anywhere transparency matters but page speed also matters — converting to WEBP is usually a clear win with no visible downside.
Yes, this conversion preserves the alpha channel — transparent areas in your PNG stay transparent in the resulting WEBP file.
For graphics with flat colors and sharp edges (like logos or icons), the visual difference is typically unnoticeable. Very fine gradients may show minor differences depending on the compression level.
In most cases, yes, often noticeably so — but the exact savings depend on the image content. Photos and complex graphics tend to shrink the most; very simple graphics with few colors sometimes compress similarly in both formats.
Yes, most modern image editors (recent versions of Photoshop, GIMP, Affinity Photo) can open and edit WEBP files directly.
Yes, this tool is completely free with no registration, no watermark, and no conversion limit.
No, the conversion happens locally in your browser using JavaScript. Your files are never uploaded to any external server.
There's no fixed limit enforced by the tool since everything runs in your browser rather than on a server. Very large files may simply take a little longer to process depending on your device.
For most everyday uses, the visual difference is negligible. If you need maximum fidelity, keep the quality setting high during export.
