CRC32 Calculator

CRC32 Calculator is a free and open-source software application whose only purpose is to calculate the CRC32 code of any file or text. It comes packed with a basic set of options that can be easily configured by users, even the ones with little or no kind of experience in such tools.

This is a portable tool, so no installation is necessary. It means that you can drop the file in any part of the hard disk and just click it to run, as well as save it to a USB flash disk or similar storage unit, in order to run it on any machine with minimum effort and no previous installers.

An important aspect to take into account is that the Windows registry and Start menu do not get updated with new entries, so there are no traces left behind after the app's removal.

The GUI is made from a small window with a simple layout, providing direct access to all main options. All you have to do is point out a file of any type by using the file browser (the drag-and-drop feature is not supported), or input text and click a button to calculate its CRC32 code. This is displayed with its decimal and hexadecimal value.

There are no other notable options provided by this software utility. For example, CRC32 Calculator does not implement buttons for copying information to the Clipboard, printing it, or exporting it to file.

As expected, the tool is undemanding when it comes to CPU and RAM, so it does not hog system resources. The CRC32 codes are displayed very fast. No error dialogs were shown in our tests, and the app did not hang or crash. Thanks to its intuitive layout and overall simplicity, CRC32 Calculator can be handled by anyone.
