Free Auto-Crop Tool for Transparent Images
Instant Bounding Box Cropping: Automatically detect and remove excess transparent space (padding) from your .png files, reducing them to their exact content dimensions.
100% Private & Secure: All image analysis and cropping operations execute entirely locally within your web browser using HTML5 Canvas. No files are uploaded to a remote server.
Batch Processing Capability: Select and process multiple images sequentially. The tool efficiently handles bulk jobs without crashing your browser.
Smart Edge Detection: The script includes an optimized alpha-threshold filter to ignore nearly invisible, semi-transparent artifacts often left behind by background removal tools.
Unrestricted Utility: Completely free to use. There are no advertisements, usage caps, premium subscriptions, or watermarks.
