Complete guide to using Checksum Verifier — a free online tool by akousa.net.
Get started in seconds — no signup required
The Checksum Verifier validates file and data integrity by computing hash values using MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, and CRC32 algorithms and comparing them against expected checksums. File checksum verification is the primary defense against download corruption, man-in-the-middle tampering, and supply chain attacks on software distribution — Linux ISOs, software installers, and firmware images all publish official SHA-256 checksums for users to verify. This tool uses the Web Crypto API so nothing is ever uploaded to a server.

Upload a file or paste text data into the input area, then select the hash algorithm matching the provided checksum. Paste the expected hash value into the comparison field and click Verify. A green checkmark confirms a match (file is authentic and intact); a red X indicates a mismatch (file may be corrupted or tampered). All hashing is performed locally.
