How to Convert PNG to WebP
WebP can reduce the size of many PNG files while retaining transparency. Quality-controlled WebP is lossy, so sharp graphics need closer inspection than photographs.
Open the PNG to WebP toolQuick answer
Transparency can remain, but color detail can still be compressed. Check edges around logos, text, and cutout subjects.
When WebP can help
Large photographic PNGs often shrink substantially as WebP. Interface graphics and simple logos may already be efficient as PNG.
Confirm the destination accepts WebP before converting an entire asset library.
How to convert PNG to WebP
- Upload the still PNG.
- Choose quality and convert to WebP.
- Compare size, transparency, and edges, then download.
Keep the original PNG as the best source for later exports.
Transparency and edge quality
WebP supports alpha transparency, but colors near translucent boundaries may be compressed and show halos on another background.
Test cutout images on the actual page background. Use higher quality or retain PNG when edges are critical.
Website delivery tips
Resize to realistic display dimensions before focusing on compression. Serve width variants when one asset appears at several sizes.
Keep descriptive filenames, dimensions, and alt text in HTML. Optimization does not replace accessibility.
