PNG to WebP Converter
100% in your browser — nothing is uploadedIf you're publishing images on a website, WebP is usually the right call: files come out dramatically smaller than PNG at near-identical visual quality, transparency survives, and every modern browser supports it. Smaller images mean faster pages and better Core Web Vitals.
For images headed to a website, WebP is usually the better container: noticeably smaller than PNG at near-identical quality, with transparency intact and support in every current browser. Because the work is local, you can batch-convert a whole folder of assets before uploading without sending anything anywhere. Keep the PNG original for archival or pixel-critical work, since WebP re-compresses for delivery rather than for mastering.
How to use the png to webp converter
- Drop a PNG file onto the converter (or click to choose one).
- The conversion runs instantly in your browser.
- Download the WebP result.
Frequently asked questions
Does PNG to WebP lose quality?
This converter uses high-quality WebP encoding, and for typical graphics the difference is invisible. Transparency is preserved. For pixel-critical archival work, keep the PNG original too.
Is WebP a good format for archiving original artwork?
For long-term archival, keep a lossless PNG or your original source file. WebP is optimized for fast delivery on the web — excellent for publishing images, but not the format you want as your single master copy.
Are my PNG files uploaded anywhere?
No. The conversion uses your browser's built-in image engine (the Canvas API), so your PNG never leaves your computer. You can verify it by loading this page, going offline, and converting anyway — it still works.
Can I convert several PNG files at once?
Yes — select or drop multiple PNG images and each one is converted to WebP and listed separately for download, all locally on your device.
