PNGcheck is software for testing and debugging PNG files. It serves as the official PNG debugger and tester.
I recently tried out pngcheck, a software that can help you verify the integrity of your PNG, JNG, and MNG files. This handy tool checks the internal 32-bit CRCs (checksums) and decompresses the image data, ensuring that everything is in tip-top shape. Additionally, one of the best features of pngcheck is its ability to dump almost all of the chunk-level information in your image in a human-readable form.
Whether you need to print basic statistics about your image, list the color and transparency info in its palette (assuming it has one), or extract embedded text annotations, pngcheck has got your back. It supports all PNG and JNG chunks, as well as almost all MNG chunks (except for PAST, MAGN, DISC, DROP, DBYK, ORDR, and pHYg).
One of the standout features of pngcheck is its command-line program with batch capabilities, allowing you to easily check the quality of all your images at once. For example, you could use the command "pngcheck *.png" to check all PNG files in a directory.
Additionally, the latest release of pngcheck includes some exciting new features. You can now colorize the output (using ANSI colors), which makes it even easier to spot any issues with your files. The verbose output for interlaced images has also been enhanced, making it clearer and easier to understand. Plus, three bugs that showed up in the most recent release of the brokensuite test images have been fixed, ensuring even greater accuracy and reliability.
Overall, I found pngcheck to be a powerful and user-friendly software that can help you ensure the quality of your image files quickly and easily. Whether you're a professional photographer, graphic designer, or just someone who wants to make sure their images are in top shape, I highly recommend giving pngcheck a try.
