Private, nothing is uploaded
Runs entirely in your browser — nothing is uploaded.
Turn PNG images into WebP, the modern web format that's much smaller at the same visual quality and still keeps transparency. It runs entirely in your browser, so nothing is uploaded, there's no account, no watermark, and you can batch freely.
Why WebP for the web
WebP typically produces files far smaller than PNG at matching quality, often a fraction of the size, which means faster page loads and less bandwidth. Crucially it supports transparency just like PNG, so logos, icons, and cut-outs keep their alpha channel while shrinking dramatically. Every modern browser (Chrome, Firefox, Edge, Safari) displays WebP, so for images you host on a site you control, it's usually the better choice than a heavy PNG.
When to stay on PNG
WebP's trade-off is reach beyond the browser. Some older desktop tools, certain editors, and a few upload forms still don't accept it. If the image needs to drop into legacy software, print workflows, or a form that only takes PNG/JPG, keep the PNG. Use WebP specifically when you control the playback surface, almost always a web page viewed in a current browser, where its smaller size pays off.
Lossy or near-lossless
The quality slider lets you balance size against fidelity. Around 90% keeps the image visually identical to the PNG while still cutting size substantially, which is the right default for most web images. For graphics with hard edges you can push quality higher to avoid any softening; for large background photos you can go lower to save more. Either way the transparency is preserved, so you don't trade the alpha channel for the smaller size.
Tips
- Use WebP for images on a website you control, much smaller than PNG, faster loads.
- WebP keeps transparency, so logos and icons convert without a white background.
- Keep PNG if the image must open in older desktop tools or print workflows.
- Quality ~90% is visually identical for most images while still shrinking the file.
