How to convert PNG to WebP
- Drop your .png files onto the box above.
- The output is already set to WebP.
- Choose a quality level. For logos and graphics with sharp edges, try 95%.
- Download the results individually or as a ZIP.
Where the big savings are
This is the conversion with the largest wins. PNG stores photographs terribly — a photograph saved as PNG is routinely five to ten times larger than it needs to be — so converting one to WebP can cut eighty percent or more.
For flat graphics, logos and screenshots the saving is smaller but still real, typically twenty to forty percent, because WebP has a lossless mode that simply compresses better than PNG does.
Transparency survives the conversion. WebP carries a full alpha channel, so a logo with a transparent background stays transparent.
When to keep the PNG
Keep PNG when the file is a working asset rather than something you publish — an image that will be reopened and edited, or handed to a designer.
Keep PNG when a tool in your pipeline demands it. Some app store submission forms, favicon generators and older build tools accept nothing else.
For anything actually served to visitors, WebP is smaller and every browser reads it.
Common questions
- Does transparency survive?
- Yes. WebP supports a full alpha channel, so transparent areas stay transparent. This is one of its advantages over JPEG, which cannot store transparency at all.
- How much smaller will the file be?
- It depends entirely on the content. A photograph mistakenly saved as PNG can shrink by eighty percent or more. A simple logo with a few flat colours might save twenty to thirty percent. Both are worth having.
- Should I use a high quality setting for logos?
- Yes. Sharp edges and text are where lossy compression shows first, so 95% or above is sensible for logos, icons and screenshots. Photographs are far more forgiving — 90% is plenty.
- Are the files uploaded anywhere?
- No. Conversion happens entirely inside your browser and nothing is transmitted.
