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.
PNG (Portable Network Graphics) offers lossless compression and full transparency support, at the cost of much larger files for photographic images — it's the right format for screenshots, logos, diagrams, and any image that needs a transparent background. WebP offers 25–35% smaller files than JPG at similar quality, plus transparency — but spotty support in older software and some upload forms, which makes it ideal for websites and apps where loading speed counts. This converter decodes your PNG and re-encodes it as WebP entirely inside your browser using the Canvas API — the file is never uploaded, so there's no size limit, no queue, and no privacy trade-off.
How to use the png to webp converter

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 there a file size limit?
No hard limit — because conversion happens on your own device, there's no server cap. Very large images are bounded only by your browser's memory.
Are my PNG files uploaded?
No. The conversion uses your browser's built-in image engine (the Canvas API). Your image never leaves your computer, which you can verify by loading this page and then disconnecting from the internet — conversion still works.
Can I convert multiple files?
Yes — select or drop several files at once and each is converted and listed for download individually.
