Why convert PNG to WebP?

WebP typically achieves 25–35% smaller file sizes than PNG at equivalent visual quality, while also supporting transparency. Smaller images load faster and improve Core Web Vitals scores.

Is PNG transparency preserved in WebP?

Yes. WebP fully supports alpha transparency, so your transparent PNGs will convert without any loss of the transparent areas.

Is WebP supported in all browsers?

WebP is supported by all modern browsers including Chrome, Firefox, Safari 14+, and Edge. If you need broad legacy support, keep the original PNG as a fallback.

What quality setting should I use?

A quality of 80–85% offers an excellent balance of file size and visual quality. For sharp graphics or logos with text, use 90–95% to avoid compression artifacts.

Can I convert multiple PNGs at once?

Yes — drop or select as many PNG files as you like. All are converted and downloaded as a single ZIP archive.

What is PNG to WebP?

PNG to WebP converts standard PNG images into Google's efficient WebP format. WebP images with transparency (alpha) are typically 25–35% smaller than equivalent PNGs, making your website faster without sacrificing visual quality.

How It Works

Drop your PNG files and choose a quality level. The browser draws each image onto a canvas and encodes it as WebP — entirely on your device. Transparency is preserved. Multiple files are packaged in a ZIP for easy download.

How to Use

1
Upload PNG images
Drop one or more PNG files onto the upload zone, or click to browse. All conversion happens in your browser.
2
Set quality
Adjust the WebP quality slider. 80–85% is ideal for photos; use 90–95% for logos or graphics with text.
3
Convert
Click "Convert to WebP". Each PNG is converted to WebP format using the browser's built-in canvas encoding.
4
Download
Save individual WebP files or download them all in a ZIP archive.
