How It Works
Convert PNG to WebP in three quick steps.
Upload PNG files

Download WebP
Save your WebP file, or a ZIP when you converted several files.
What is a PNG to WebP converter?
WebP is an image format developed for the web that typically produces much smaller files than PNG at similar visual quality. Converting PNG images to WebP reduces page weight, which improves loading speed and Core Web Vitals scores on websites, shops and blogs.
Keep your original PNGs as masters. WebP is ideal for publishing, but PNG is better when you plan to keep editing.
Smaller files
WebP is usually noticeably lighter than PNG, especially for photos and gradients.
Transparency supported
WebP has an alpha channel, so transparent PNG backgrounds stay transparent.
Saved at 92% quality
Output is encoded as lossy WebP at 92% quality, a good balance between size and sharpness.
Needs browser support for WebP export
Chrome, Edge, Firefox and Opera can create WebP files in the browser. If your browser cannot, the conversion shows an error.
