CRC32 Calculator

CRC32 Calculator is a tiny and straightforward piece of kit that enables you to calculate the CRC32 signature of any files, regardless of its extension. You can use this alphanumerical value to find out if two files are identical or different by their CRC hashes.

Doesn't need installation

The tool's packed in an .exe file that can be copied anyplace on the disk or to a USB flash drive to fire it up on any machine without any installation.
It doesn't insert new entries into the system registry, need DLLs or other components to work properly, or generate extra files on the disk without letting you know about it.

Simple GUI for calculating CRC32 hashes

When it comes to the interface, CRC32 Calculator opts for a small window with an outdated design and single structure. Although the window can be resized, the elements it contains are not refitted to the new dimension.
You can click a button to bring up the file browser and locate a file whose CRC hash you want to calculate. Unfortunately, the drag-and-drop method isn't supported.
The alphanumerical value is immediately calculated and displayed, and can be easily selected to copy it to the Clipboard through the context menu or by triggering the Ctrl+C key combination.

Evaluation and conclusion

Although CRC32 Calculator hasn't received updates for a long time, we haven't experienced any compatibility issues with later Windows models in our tests. It had a low impact on the workstation's performance and calculated CRC32 checksums quickly while remaining light on CPU and RAM usage.
To wrap it up, this utility may not contain a particularly rich set of options and customization preferences, but it delivers a simple and straightforward method for calculating CRC32 hashes to compare files. It's geared toward all sorts of users, even those less skilled with hash tools.
