About the Crop PNG Tool
Cropping a PNG with a transparent background is tricky with cloud tools that flatten transparency. DCPIXEL's PNG cropper preserves the alpha channel through the entire cropping operation, ensuring your transparent logos and UI elements remain crisp and correctly layered after cropping.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.
Free — No Account, No Limits
DCPIXEL is completely free with no daily limits, no watermarks, and no registration. We never process your files on our servers, so we can offer this permanently at no cost.
