PNGCropper is a free, privacy-first image cropper that runs entirely in your browser.
PNGCropper is a focused tool for one job done well: cropping images — especially PNGs — quickly and cleanly. The home tool crops to any ratio, exact pixel size or a circle, keeps transparency, and exports PNG, JPG or WebP. Around it are pages tuned for specific needs: circle crops, profile pictures, square crops, exact-size crops and more.
Your images are processed on your own device using the browser’s canvas. Nothing is uploaded to a server, so private photos, ID images and work screenshots never leave your computer or phone. Recent crops are stored only in your browser’s local storage and can be cleared at any time.
The tools are free to use with no account and no watermark. The site is supported by advertising, kept clearly separated from the tools. See our privacy policy for how analytics and ads work.
