About this tool: PNG to WebP converter
PNG is useful for transparent graphics and screenshots. WebP can reduce delivery size while keeping alpha transparency, but lossy conversion is not a pixel-identical archive copy.
How to convert PNG to WebP
- Choose up to five PNG images, each within 15 MiB and 40 megapixels.
- This page accepts PNG images and exports WebP. Choose another converter below for a different input format.
- Process the image, compare the result dimensions and file size, then download a separate copy. Keep the original.
When to use this tool
A WebP copy can suit a website that accepts the format and needs transparency. Start from the original PNG, choose a quality setting and inspect thin lines, lettering and edges against both light and dark backgrounds.
Check before downloading
This browser export uses a quality setting and should not be treated as a pixel-identical PNG archive. Transparency can remain, but detail and file size depend on the source. The tool reports the actual size rather than promising a fixed percentage reduction.

A few things you might wonder.
Which files can I add?
This page accepts PNG images and exports WebP. Choose another converter below for a different input format.
What happens to transparent areas?
WebP preserves transparency. Quality settings may change image detail; keep the original for further editing.
Will the converted image always be smaller?
No. Encoding can increase file size, especially for an already optimized source. Compare the actual byte sizes before downloading.
