info About this tool
Convert bulky PNGs to efficient WebP images while preserving transparency. Speed up your website. You can adjust the WebP quality to balance file size against visual fidelity. When your browser supports it, this conversion runs locally on your device and the file is never uploaded.

File size: WebP output is typically 30–50% smaller than the original PNG using lossless WebP compression.

Quality: This converter uses lossless WebP mode for PNGs: every pixel is preserved exactly, including full transparency.

help FAQ

Is transparency preserved in the WebP output?

Yes. PNG's alpha channel (transparency) is fully preserved in the WebP output. Transparent pixels remain transparent.

Is this lossy or lossless conversion?

For PNGs, we use WebP lossless mode, which preserves every pixel exactly: no quality loss, just a smaller file.

How much smaller will my PNG be?

Typically 30–50% smaller. Lossless WebP is significantly more efficient than PNG's compression algorithm.

Can I use WebP for logos and icons?

Yes: WebP is ideal for logos and icons. It supports transparency and compresses flat-color graphics very efficiently.
