Batch PNG to WebP with Transparency Preserved

Transparent PNG files — icons, logos, product cutouts, UI elements — are the most common images that need converting to WebP. Unlike JPEG, WebP fully supports alpha-channel transparency, making it the perfect PNG replacement for the web.

This tool converts multiple transparent PNGs to WebP in one batch. Each converted file preserves every transparent pixel from the source. Use lossy mode at quality 85 for typical icons and product photos (25–35% smaller than PNG), or lossless mode for pixel-perfect output that reduces file size by 10–20% without any quality change.

All processing happens in your browser via the Canvas API. Your image files never leave your device — no server upload, no account required. Drop your PNGs, convert, and download individually or as a ZIP archive.
