PNG to WebP Converter

Convert PNG images to WebP and shrink their file size, right in your browser.

ToolsSoup's PNG to WebP Converter is a free online tool that turns PNG images into modern WebP files right in your browser. WebP keeps the visual quality of a PNG while producing a much smaller file, so your images load faster on the web. Upload a PNG, choose a quality level, and download the WebP in seconds — with no uploads, no watermarks, and no sign-up. Your images never leave your device.

What is a PNG to WebP converter?

A PNG to WebP converter rewrites a PNG image in Google's WebP format. WebP supports the same lossless quality and transparency that PNG offers, but compresses far more efficiently — often cutting file size by 25–70% with no visible difference. Smaller images mean faster page loads, better Core Web Vitals scores, and less bandwidth. This tool draws your PNG onto an HTML canvas and re-encodes it as WebP entirely on your device.

How to convert PNG to WebP online

Converting a PNG to WebP with ToolsSoup takes just a few seconds:

  1. Click Choose a PNG image and select the PNG you want to convert.

  4. Download your WebP file with one click and see how much smaller it became.

Why convert PNG to WebP?

PNG is great for screenshots, logos, and graphics with sharp edges, but its files can be large. WebP delivers the same look at a fraction of the size, which is why it is now supported by every major browser. Converting your PNGs to WebP speeds up your website, saves storage, and reduces the data your visitors download — without sacrificing transparency or clarity.

Frequently asked questions

Is this PNG to WebP converter free?

Yes. Every tool on ToolsSoup is completely free to use, with no account, sign-up, watermarks, or hidden limits.

Are my PNG images uploaded to a server?

No. The conversion happens locally in your browser using the HTML canvas, so your images are never uploaded, stored, or seen by anyone but you.

Does WebP make my image smaller?

Almost always. WebP compresses far more efficiently than PNG, so the converted file is usually 25–70% smaller. The tool shows you the new size and the exact percentage saved after each conversion.

Does converting to WebP keep transparency?

Yes. WebP supports an alpha channel just like PNG, so transparent backgrounds and edges are preserved in the converted image.

Will I lose quality converting PNG to WebP?

WebP can be lossy or lossless. At a high quality setting the difference is invisible to the eye. Lower the quality slider to make the file even smaller, or keep it high to stay close to the original PNG.

Can browsers display WebP images?

Yes. WebP is supported by all modern browsers including Chrome, Firefox, Safari, and Edge, making it a safe choice for websites and apps.
