What this tool is for
Convert PNG graphics and photos to WebP for lighter web delivery while retaining transparent areas in modern browsers.
How to use it
- Choose a PNG image up to 50MB.
- Select Process Image.
- Wait while the browser encodes a WebP copy.
- Download it and compare transparency, sharpness, and byte size.
What happens to your image
The browser encodes decoded PNG pixels as WebP locally. Transparent regions are retained by modern WebP encoders, while source metadata is omitted.
Practical uses
- Reduce transparent logo size for a website.
- Optimize PNG product images for an online catalog.
- Create lighter interface illustrations.
- Prepare transparent assets for a modern web app.
Transparency with modern compression
PNG is lossless and often large for photographs or complex graphics. WebP can store transparency with more compact compression, though exact savings depend on colors, detail, and source optimization.
Important limitations
- Some older software cannot open WebP.
- A simple, optimized PNG may not become much smaller.
- Animation is not preserved.
- Always inspect sharp edges and small text after conversion.
Frequently asked questions
Will WebP keep PNG transparency?
Yes, current browser encoders preserve transparent pixels.
Is WebP smaller than PNG?
Often, especially for complex images, but the exact result depends on the source.
Can I edit WebP later?
Many modern editors support it, but keep the original PNG if you need maximum editing compatibility.
Is WebP good for logos?
It can be good for web delivery with transparency; keep a vector or lossless master for future editing.
