About the PNG to WEBP Converter
The PNG to WEBP Converter turns Portable Network Graphics (PNG) images into WebP (WEBP) files right inside your web browser. WEBP keeps transparency like PNG while making files much smaller, so it is the perfect replacement for PNG graphics on websites.
PNG is a lossless format that preserves every pixel exactly and supports full transparency. It is ideal for logos, icons, screenshots, illustrations and images with text, although photos saved as PNG are usually much larger than JPG.
WEBP is a modern format created by Google that produces files 25–35% smaller than JPG or PNG at similar quality, and it supports transparency and animation. All modern browsers support it, but some older apps, editors and upload forms still do not accept WEBP files.
WEBP uses lossy compression, so use the quality slider to balance file size and detail; 85–92% looks virtually identical to the original. Transparency is preserved, because both PNG and WEBP support transparent backgrounds. You can convert dozens of images at once, optionally limit the maximum width to shrink large photos, and download everything as a single ZIP file. Because the conversion runs locally on your device, your pictures are never uploaded to a server.
How to use the PNG to WEBP Converter
- Drop your PNG files into the upload area, click to browse, or paste an image.
- Adjust the quality or maximum width if needed.
- Wait a moment while each image is converted to WEBP on your device.
- Download files individually or click Download all (ZIP).
