Upload static PNG graphics and create WebP files without leaving this page. Choose lossless, balanced, smaller-file, or custom quality, preserve transparency by default, and compare the result before download.
Preserve APNG animation in WebPSupports many aliases including jpeg.
Create WebP copies of static PNG photos, screenshots or transparent graphics. Choose how to encode the image, compare the result and its file size, then download the WebP.
A frontend team can test WebP copies of transparent PNG product cutouts, icons, or interface graphics. Compare alpha edges over the real page background and verify that the size saving remains worthwhile at the chosen quality.
WebP can lower payload for screenshots and flat-color assets, but the best setting depends on edge detail and downstream recompression. If the PNG is animated APNG, first confirm the intended still or animation behavior rather than assuming one preview represents every frame.
Try Lossless for lettering, icons and diagrams when avoiding the WebP lossy encoding step matters more than the smallest file. The output is still a new WebP file and may be larger than the PNG.
Balanced starts at quality 82. Smaller uses quality 68 and can lose more detail. Compare faces, gradients and small text at the size where the image will be used; keep the result that gives an acceptable size and appearance.
Select Custom to enable the quality slider from 1 to 100. A higher value does not guarantee a smaller file or restore missing detail. Custom 100 is not the Lossless mode.
Inspect small letters, icon edges and semi-transparent areas in the result. If a lossy mode makes those details unsuitable, try Lossless from the original PNG. Check whether the receiving app accepts WebP before replacing the PNG.
Compare the actual PNG and WebP file sizes. Conversion can produce a larger file, especially with Lossless. Keep the original PNG so you can make another export without repeatedly converting an already compressed result.
Try Lossless when avoiding lossy WebP encoding is important for text or graphics. Balanced uses quality 82, Smaller uses quality 68, and Custom lets you set lossy quality from 1 to 100. Compare the finished file rather than assuming one mode is best for every PNG.
No. Custom controls lossy WebP quality. Select the separate Lossless mode to avoid that lossy encoding step. Neither mode restores detail missing from the source or keeps the original PNG file bytes.
Yes. Leave Strip alpha off to retain the decoded transparency in WebP. Enabling Strip alpha replaces transparent areas with the selected background. Inspect soft or semi-transparent edges in the result.
Size depends on the image and encoding mode. A simple PNG can already be compact, and Lossless WebP can be larger. Compare actual bytes and use the PNG if a WebP copy gives no useful saving or is not accepted by the receiving app.
This guidance is for static PNG images. Use the dedicated APNG to WebP page linked above when animation is your task, and check playback there before replacing the animated source.
