How to Use Hash Checker

Paste the expected hash

Enter the hash value provided by the original source (software download page, file sender, etc.) into the first field.

Paste or compute the actual hash

Enter the hash of your downloaded or received file into the second field. You can also compute a hash from text input.

View the comparison result

The tool instantly shows whether the two hashes match exactly. A match confirms file integrity; a mismatch indicates corruption or tampering.

About Hash Checker

Hash checker online — verify file integrity by comparing hash values instantly for free. Paste two MD5, SHA-1, SHA-256, or SHA-512 hash strings and get immediate visual confirmation of whether they match. Essential for verifying software downloads, checking file integrity after transfer, and validating data authenticity. Case-insensitive comparison works with any hexadecimal format. Perfect for IT professionals, developers, and security-conscious users. All processing happens locally in your browser.

Frequently Asked Questions

How to verify a file hash online?▾

Paste the expected hash from the source and the actual hash of your file. Our tool compares them instantly and shows whether they match, confirming file integrity.

How to check an MD5 checksum?▾

Paste the MD5 hash provided by the source and your file's MD5 hash into the two input fields. If they match exactly, your file is intact and unmodified.

How to verify a SHA-256 hash for a software download?▾

Copy the SHA-256 hash from the download page, paste it alongside the hash you computed for the downloaded file, and verify they match.

How to compare two hash values?▾

Paste both hash values into the comparison fields. The tool performs an exact character-by-character comparison and shows match or mismatch instantly.

How to check if a downloaded file is safe?▾

Compare the hash of the downloaded file against the hash provided by the official source. If they match, the file has not been tampered with or corrupted.

How to use hash verification for data integrity?▾

Hash the data before and after transfer using the same algorithm. Compare the two hashes — matching values confirm the data was not altered during transmission.

How to check a SHA-512 hash?▾

Paste the expected and actual SHA-512 hash values into the two fields. SHA-512 produces a 128-character hexadecimal string for the highest level of verification.

How to verify a checksum on any operating system?▾

Use our browser-based hash checker on any OS — Windows, Mac, or Linux. No software installation needed. Just paste the hash values and compare.
