Why convert PNG to WebP?
Convert PNG to WebP to make web graphics much smaller while keeping transparency — that means faster pages and better SEO.
What is PNG?
PNG is a lossless image format with full transparency support. It keeps every pixel perfect, which makes it ideal for logos, icons, screenshots and graphics with sharp edges — though files are larger than JPG.
What is WebP?
WebP is a modern image format from Google that’s typically 25–35% smaller than JPG or PNG at similar quality, with support for both transparency and animation. Some older software still can’t open it.
Is it private?
Completely. Unlike most “online converters” that upload your images to a server, this tool converts each PNG fileright inside your browser. Your images are never uploaded, stored or seen by anyone — not even us. It even keeps working offline once the page has loaded.
Frequently asked questions
Are my PNG files uploaded anywhere?
No — the conversion runs in your browser, so your files never leave your device.
Is it really free?
Yes: no sign-up, no watermark, and no limit on how many files you convert.
Can I convert in bulk?
Yes — add many PNG files at once and download them together as a ZIP.
