CRC Calculator

Updated: Jan 2, 2018

CRC Calculator is an online tool to compute the CRC-16 & CRC-32 checksum of a string or file locally on your browser. This hash can be used to verify the integrity of the data during transmission. You can provide the expected hash and compare the calculated CRC checksum with it. The CRC hash can be generated in Base64, Hex or Integer formats. The input can be provided in Plain Text, Base64 or as a binary file which you can select from your machine. Hit the Calculate button to generate and check the CRC value

Your file or data will NOT be uploaded. All processing takes place locally inside your browser.

Input: Paste text below


CRC checksum in Hex
CRC checksum in Base64
CRC checksum in Integer
Hash Matched:
Whether the calculated hash matched with the checksum you provided
CRC is an old & widely used algorithm to verify the integrity of data during transmission. It has been used in networks & storage devices to detect data corruption.
Input Type
The type of the input text (not applicable for files).
Plain Text
Lore ipsum dolor sit amet
Click on Browse File and select a file for Binary Input Type
CRC hash to compare
The hash to compare to in Base64, Hex or Integer format
The CRC algorithm to use for calculating the checksum or hash. You can choose between CRC-16 & CRC-32
