—About PNG to WebP Converter
PNG to WebP converts a PNG into WebP, which supports both transparency and strong compression. It is ideal for web graphics that need an alpha channel but a smaller file than PNG.
WebP keeps PNG’s transparency while compressing much better. Converting locally gives you a lighter, alpha-capable web image without an upload.
Step by step
- Drop a PNG image into the WebP converter.
- Adjust the WebP quality if you want lossy compression, or keep it high for near-lossless.
- Preview the result, transparency included.
- Download the WebP file.
What it offers
- Transparency-preserving WebP output
- Quality slider for size control
- Preview with transparency intact
- PNG converted in the browser
Tips for best results
- Use WebP for transparent web graphics where you would otherwise reach for a heavy PNG.
- Provide a PNG fallback for environments without WebP support.
- Keep quality high for graphics with sharp edges to avoid fringing.
