Good to know

The PNG to WebP converter converts up to 20 PNG graphics at once directly in your browser via canvas into WebP, with a quality slider and a default of 86. Unlike conversion to JPG, the PNG's transparency is fully preserved, since WebP supports an alpha channel.

Multiple results can be downloaded together as a ZIP, with a visible size comparison per file. Check the transparency of logos and UI graphics with sharp edges after conversion.

Typical use cases

Compress transparent logos for the web

Convert PNG logos with transparency to WebP to reduce file size without losing the transparent background.

Batch-optimize UI graphics for websites

Process multiple PNG icons or illustrations at once and download them together as a ZIP.

Tips for better results

Check transparency at edges

For logos or UI graphics with sharp edges, check whether transparency stays clean after conversion, especially at lower quality.

Adjust quality for illustrations

For flat illustrations with few colors, a quality lower than the default of 86 can often be used without visible loss.
