Frequently asked questions
Does WebP preserve PNG transparency?
Yes. WebP supports full alpha-channel transparency, just like PNG. Your transparent areas will be preserved when converting from PNG to WebP.
How much smaller will my PNG be after converting to WebP?
Google's benchmarks show lossless WebP is 26% smaller than PNG. For photographic PNGs, lossy WebP can achieve 60–80% reduction. Results vary by image content.
Should I use lossless or lossy WebP for PNG conversion?
For logos, icons, and graphics with flat colors or text, use lossless WebP (quality 100 in the converter). For photographs accidentally saved as PNG, use lossy WebP at quality 80–90 for much better compression.
Are my PNG files uploaded to a server?
No. The conversion happens entirely in your browser using the Canvas API. Your files never leave your device.
