PNG to WEBP Converter
Convert PNG images to WEBP free, right in your browser.
Quick answer: To convert PNG to WEBP free, use a converter that re-encodes the actual pixel data — renaming the file extension does not change the format. This tool decodes your PNG and re-encodes it as a real WEBP directly in your browser, with no upload, signup, size cap or watermark.
This tool converts PNG images to real WEBP files by re-encoding the pixel data — not by renaming the extension. Everything happens locally in your browser: your image is never uploaded to any server.
PNG is lossless and supports transparency, which makes it the standard for logos and artwork. WEBP is Google's modern web format — smaller than JPG and PNG at similar quality, with transparency support.
How it works
- Drop a PNG file (or several) onto the upload area, or tap to choose from your device.
- Each image is decoded and re-encoded as WEBP in your browser using the canvas engine.
- Preview the result and download each file, all without your image leaving your computer.
Good to know
- Very large images (over ~50 megapixels) can exceed browser memory limits.
- Animated images are converted using their first frame only.
Frequently asked questions
Is this PNG to WEBP converter really free?
Yes — completely free, with no signup, no daily limit, no watermark and no file cap. Because the conversion runs in your own browser, it costs us almost nothing to offer, so there is no catch.
Is my image uploaded to your server?
No. The file is read and converted entirely inside your browser using the HTML5 canvas engine. It never leaves your device, which also makes this faster than upload-based converters.
How much smaller will my WEBP be?
Typically 25–70% smaller than the PNG, depending on the image. Graphics with large flat areas compress the most. You can adjust the quality slider to trade size against fidelity.
