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.
