What this PNG to WebP converter does
This free PNG to WebP converter transforms PNG images into WebP files directly in your browser. It is useful when you want a modern image format that often gives smaller file sizes for websites, landing pages, blogs, stores, and apps.
Unlike JPG, WebP can preserve transparency, which makes it a good choice for product cutouts, UI assets, logos, and design elements that still need an alpha channel.
How PNG to WebP conversion works
Read the PNG
The converter loads your PNG file locally in the browser and keeps its original width and height.
Render the pixels
The image is drawn to a canvas so the browser can export the same content into a different format.
Export as WebP
The canvas is encoded as WebP using your selected quality level, then shown as a preview and download link.
Worked example
Imagine you have a transparent product PNG that is 1800 × 1800 pixels and weighs 2.6 MB. You want to use it on a product page without losing the transparent background.
Input
- Format: PNG
- Dimensions: 1800 × 1800 px
- Background: Transparent
- Goal: Reduce file size for a website
Output at 90% quality
- Format: WebP
- Dimensions: 1800 × 1800 px
- Transparency: Preserved
- Typical result: smaller and more web-friendly than the original PNG
This is a strong fit for ecommerce cutouts, UI graphics, badges, overlays, and blog images where both transparency and fast loading matter.
When to use WebP instead of PNG

- You want smaller image files for faster websites.
- You still need transparency support.
- You are optimizing product images, UI assets, or landing page graphics.
Keep PNG when
- You need maximum compatibility with older workflows.
- You prefer a traditional lossless source file for design handoff.
- You are not optimizing images for web delivery.
