How to use PNG to WebP
- Drop your PNG image onto the upload area, or click to choose a file.
- Adjust the quality setting if needed and check the preview.
- Check the file size, then download your WebP image.
Why use PNG to WebP
- WebP files are often much smaller than PNG files.
- Faster page loading for your website.
- WebP can keep transparency, so logos and icons can stay transparent.
Why convert PNG to WebP?
PNG files keep every pixel, but they can be heavy, especially for photos and large graphics. WebP can store the same kind of picture, including transparency, in a much smaller file. Google reports that lossless WebP images are about 26% smaller than PNG images, and lossy WebP gives even smaller files.
Things to check
This tool saves a lossy WebP using the quality slider. Look at the preview, especially around text and sharp edges, before you download. Creating WebP needs a browser that can export it, such as current Chrome, Edge or Firefox.
Tips for best results
- Keep your original PNG as the master copy.
- Check the preview to make sure edges and text still look sharp.
- Resize large images first for an even smaller file.
