HashZilla is a freeware tool to compute checksums and hashes for files.


Currently HashZilla can calculate the following hashes and checksums:

  • MD5
  • SHA1
  • SHA224
  • SHA256
  • SHA384
  • SHA512
  • CRC32
  • Adler32


Supported operating systems: Windows XP/Vista/7/8/8.1/10.

HashZilla does NOT require NET Framework or additional libraries.

Installation and uninstallation

HashZilla is a portable application. It is distributed in self-extracting archive.

1. Close the application if it is running.

2. Delete the directory that contains the HashZilla executable file.

3. Remove the self-extracting package, if you don't plan to use it in the future.

Computing hashes and checksums for a file

1. Run the HashZilla.exe file.

HashZilla executable file

2. Click Open file, select a file that is stored on any local drive or memory card connected to your computer.

Open file

3. Select the hashes and checksums that you want to compute.

Hashes and checksums

Note. Hash/checksum calculation for files larger than 500 MB may take a considerable amount of time. Therefore it is recommended to select only the necessary hashes and checksums.

4. Click on the Calculate button.


To skip calculation of the current hash and start computing the next selected hash or checksum, click on Skip.


To stop computing click on Cancel.
