About PNG and WebP
PNG stores every pixel exactly. That makes it a good format for editing, and a heavy one for a website: a single product photo or hero image saved as PNG can weigh several megabytes, and slow pages lose visitors and search ranking.
WebP is the image format Google built for the web. It compresses photos far better than PNG and still supports a transparent background, so you can use it for logos and cut-out product shots as well. Every current browser displays WebP, including Safari on iPhone and Mac, and most site builders, CMS platforms and online stores accept it.
This converter turns your PNG images into WebP on your device. Drop one image or a whole folder, and download the results one by one or as a ZIP. Nothing is uploaded, so you can convert client work and unreleased designs without sending them anywhere.
When to keep the PNG
The converter saves lossy WebP at quality 80. At normal viewing size the result looks the same as the original, but zooming in on small text or sharp edges can show slight softness. Keep the PNG as your master copy, and convert again whenever you need a web version.
Some places still refuse WebP: older desktop software, a few print services and some email clients. If an upload form rejects your WebP, a JPG or the original PNG will work there.
Questions and answers
Is it safe?
Yes. Conversion happens in your browser, and your images are never uploaded.
How much smaller will the WebP be?
Photos saved as PNG often shrink five to ten times. Screenshots and flat graphics shrink less, usually by a third to a half.
Is the transparent background kept?
Yes. WebP supports transparency, so logos and icons keep their clear background.
Will the image lose quality?
Slightly. The converter saves lossy WebP at quality 80, which looks the same as the PNG at normal viewing size. Keep the PNG as your editable original.
Does it work in Safari?
Yes. Safari cannot save WebP on its own, so the page loads a small encoder into your browser the first time you convert. The image still stays on your device.
