Frequently asked questions
About PNG to WebP
PNG to WebP is a practical website-speed fix. Large PNG screenshots, product images, interface graphics, and blog images often become much smaller as WebP while still looking sharp. Smaller image files help pages load faster, especially on mobile. WebP can keep transparency, unlike JPG, so it is useful for logos, cutouts, UI images, and graphics with transparent backgrounds. The best settings depend on the image: screenshots need enough quality to keep text readable, while photos can usually tolerate stronger compression. After converting, compare the WebP at the size it will appear on your site. Tiny text, thin lines, and soft shadows are the first places quality loss shows up.
