About These Formats
Convert PNG to WebP to retain alpha transparency while adjusting the balance between file size and visual quality. WeLoveConvert uses the browser WebP encoder with lossy compression; the quality slider does not enable a lossless mode, even at 100. Start at 90 for logos or screenshots, compare fine text and gradients with the original, and keep your PNG when exact pixel preservation matters. File size depends on the image: small graphics can become larger after conversion. Transparent areas are preserved, but visible colors may change slightly. Processing takes place on your device without uploading the image to our servers.
