How to use Remove a Border from a PNG
- 1. Upload the framed PNG. Add the image that has a uniform border baked into it, such as framed.png, that you want automatically detected and cropped away.
- 2. Set the color tolerance. Adjust Color tolerance (%) to control how much variation in the border's color is still treated as part of the frame rather than the actual content.
- 3. Download the cropped PNG. Save the result, such as framed.png with the solid border cropped away, once the detected frame has been removed and only the content area remains.
When to use Remove a Border from a PNG
Remove a Border from a PNG auto-detects a uniform border baked into an image and crops it away, without needing you to measure the frame's exact pixel width yourself. It suits scanned images and exported graphics that came with an unwanted frame attached.
- Cleaning up a scanned document. A scanned page picks up a dark border from the scanner bed's edge. Auto-detecting and cropping that border leaves just the document content.
- Removing a screenshot tool's frame. A screenshot utility adds a decorative window frame around every capture by default. Cropping that frame away leaves a clean image of just the content.
- Fixing an exported graphic with unwanted padding. A design tool exports a graphic with a uniform colored margin that was not part of the intended artwork. Cropping it away restores the graphic to its actual bounds.

About the Remove a Border from a PNG tool
Remove a Border from a PNG runs as plain JavaScript in your browser tab, with no server behind it. Auto-detect and crop out a uniform border baked into a PNG. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's PNG Tools section, 108 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Color tolerance (%) setting, and the result refreshes the moment you change it. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
