How to Crop a PNG Online

Upload your PNG by dragging it onto the upload area or clicking "Browse Files". Once loaded, the image appears in the crop canvas - drag to draw your selection area, or drag the handles to adjust it. Set a precise width and height in pixels using the dimension inputs, or lock an aspect ratio with the preset buttons.

When your selection is ready, click "Crop PNG" - the file is sent to our server, cropped pixel-precisely with ImageMagick, and returned as a download. No signup needed and files are auto-deleted after processing.

Aspect Ratio Cheat Sheet

Pick the ratio first, then drag the box over the part you want to keep. These are the ratios people crop to most:

Cropping Tips

  • Turn on the rule-of-thirds grid and place your subject on a line or crossing point.
  • Trim empty transparent margins around logos so they line up properly in layouts.
  • Crop before you upscale - enlarging only the part you keep gives a sharper result.
  • Crop screenshots to the area that matters - smaller, clearer and lighter.

Lossless and Transparent

Cropping only removes pixels - it never resamples the ones you keep. Your cropped PNG is pixel-for-pixel identical inside the selection, including every transparent and semi-transparent pixel.

Want a cut-out instead of a rectangle? Make the background transparent first, then crop away the empty space.

Frequently Asked Questions

Crop it here - the output is always a PNG, so transparent and semi-transparent pixels stay exactly as they were. Avoid saving a cropped PNG as JPG, which fills transparency with a solid color.

No. Cropping only removes the pixels outside your selection. The pixels you keep are copied exactly, with no resampling or recompression loss.

Type the width and height into the Size fields under the preview. The crop box snaps to those exact pixels and you can drag it into position.

Choose the 1:1 ratio and select the area you want. Most platforms display a square upload as a circle automatically, so a square crop is all you need.

Usually yes, because fewer pixels are stored. For the smallest file, run the cropped PNG through the PNG optimizer afterwards.
