Why use this tool?
WebP files are typically much smaller than PNG while keeping full transparency support — great for faster-loading websites and app assets. This tool re-encodes your images locally using the Canvas API; nothing is uploaded.
Frequently asked questions
Is this PNG to WebP converter really free?
Yes — 100% free, no signup, no watermark, no file limit.
Are my PNG files uploaded to a server?
No. Conversion happens entirely inside your browser using the Canvas API. Your images never leave your device.
Does converting PNG to WebP keep transparency?
Yes — WebP supports an alpha channel just like PNG, so transparent areas are preserved regardless of the quality setting.
Does this work in every browser?
WebP encoding needs a modern browser — Chrome, Firefox, Edge, or Safari 16+. This page automatically detects support and warns you if your browser can't create WebP files.
