Convert PNG to WebP for Smaller Files
WebP is a modern image format that often produces smaller files than PNG, especially for images with many colors. Importantly, WebP still supports transparency. If your site already supports it, converting large PNGs to WebP can speed up pages without changing how logos or illustrations look. This page uses local processing in your browser. Avoid changing the format if the target application does not support it. Smaller sizes also help visitors on slow connections, but test the result in several browsers before replacing site assets, and keep the original PNG as a backup.

Quick guide
How it works Convert PNG to WebP for Smaller Files
-
Choose the PNG to make lighter
Open a logo, illustration, or screenshot in PNG format. Check whether there are transparent areas that must be preserved.
-
Choose WebP and set the quality
Change the target format to WebP, then start at 80–90 percent quality. High quality keeps text edges sharp, while the file is usually still smaller than PNG.
-
Test in a browser and the target app
Download the result, then open it in Chrome, Firefox, or the app that will use it. Make sure transparent backgrounds stay clean and there are no strange colors at the edges.
FAQ
Frequently asked questions
Is WebP always smaller than PNG?
For many images, yes, but not always. Images with few colors or simple patterns may not differ much. Compare the results before replacing all assets.
Does PNG transparency remain in WebP?
Yes, WebP supports alpha transparency. Check the result on light and dark backgrounds to make sure the edges are clean.
Do all browsers support WebP?
Modern browsers generally do. However, older apps, email, or certain platforms may not accept it yet. Provide a JPG or PNG fallback if needed.
Is WebP suitable for email?
Not necessarily. Many email clients do not display WebP well, so JPG or PNG is safer for attachments. Use WebP mainly for website assets.
