WebP offers both lossless and lossy modes, making it a direct improvement over PNG for many use cases. This tool converts PNG to WebP using the browser's native WebP encoder, which provides high-quality output with significantly smaller file sizes than PNG. WebP lossless images are typically 26% smaller than PNG, and WebP lossy images at comparable quality are 25–34% smaller than JPEG. Dockitt performs the conversion entirely in your browser.

How to use

  1. Click 'Choose PNG' and select the PNG image you want to convert.
  2. Click 'Convert to WebP' and wait while the image is processed.
  3. Download the WebP file.

FAQ

Does WebP support transparency like PNG?

Yes. WebP supports full alpha channel transparency, the same as PNG. Unlike JPEG, WebP can represent transparent areas correctly. If your source PNG has transparency, the converted WebP file will also have transparency in the same places.

Is WebP smaller than PNG?

Yes, in most cases. WebP lossless mode (used when converting from PNG) typically produces files around 26% smaller than equivalent PNG files. If the tool uses lossy WebP, the savings can be 50–70% compared to PNG for photographic content.

Will converting PNG to WebP reduce image quality?

The browser's native WebP encoder used by this tool applies a high-quality setting. For typical images, the output will be visually indistinguishable from the source PNG. Minor differences may be visible in areas of very fine detail when comparing at pixel level, but for practical use the quality is preserved.

Should I use WebP instead of PNG on my website?

For most web use cases, yes. WebP provides smaller file sizes (improving page load speed) while maintaining comparable quality. All modern browsers support WebP. The main reason to keep PNG is if you need maximum compatibility with very old browsers or applications that do not support WebP.

Does the WebP output preserve transparency?

Yes. If your source PNG has transparent areas, the WebP output will preserve them. WebP's alpha channel support is equivalent to PNG's.

Is the conversion done in my browser or on a server?

The conversion runs entirely in your browser using the Canvas API. Your image is never uploaded to any server.
