What is PNG to WebP?
PNG to WebP converts PNG graphics, logos and photos to WebP while keeping their transparency. Use quality 100 for lossless WebP — ideal for logos and screenshots — or 75–85 for photos, which usually makes them a fraction of the PNG size.

Troubleshooting
- Edges of my logo look soft Use quality 100 for lossless WebP; lossy WebP can soften fine edges.
- The page says the image is too large for this device Very large pictures have to fit in your browser's memory. Close other tabs or use a computer.
- Need a different format? Open the Image Converter — it reads 10 formats and writes 7.

FAQ
Does WebP keep PNG transparency?
Yes. WebP supports an alpha channel in both lossy and lossless modes.
Lossless or lossy WebP?
Quality 100 saves lossless WebP, best for logos and screenshots. Photos look great at 75–85 and are far smaller.
Is my image uploaded?
No. It is decoded, converted and checked in your browser; the file never leaves your device.
