Hash Compare Tool

Paste two hashes and instantly see whether they match — case-insensitive, whitespace-tolerant, works with any hash format.

Hash Compare Tool

Why compare hashes with a tool?

Eyeballing two 64-character strings is exactly the kind of task humans are bad at — it is easy to confirm the first and last few characters match while a difference hides in the middle. This hash compare tool does the comparison properly: paste the checksum a website published into one box and the value you calculated into the other, and you get an unambiguous match / mismatch verdict the moment you finish typing.

The comparison is forgiving of formatting noise: leading and trailing whitespace is stripped, letter case is ignored (ABC123 equals abc123), and a leading 0x prefix is removed. It works with any hex-encoded value — SHA-256, SHA-512, MD5, SHA-1, CRC32, HMACs, or anything else. On a mismatch, the tool reports both lengths and the position of the first differing character, which quickly reveals truncated pastes or comparing a SHA-256 against an MD5 by mistake.

Typical workflow

Download a file, compute its checksum with the file checksum calculator, then paste the published value and your result here. A match confirms your download is bit-for-bit identical to the original. Like every tool on this site, comparison happens locally in your browser — the hashes you paste are never sent anywhere.

§ Frequently Asked Questions

Are the hashes I paste sent to a server?
No. Comparison happens entirely in your browser with JavaScript. Nothing you paste is transmitted or stored.
Is the comparison case-sensitive?
No. Hexadecimal hashes are case-insensitive, so ABC123 and abc123 are treated as equal. Surrounding whitespace and a leading 0x prefix are also ignored.
The hashes have different lengths — what does that mean?
Different lengths usually mean the values come from different algorithms — for example MD5 is 32 hex characters while SHA-256 is 64 — or one value was truncated when copying. Recompute with the algorithm the publisher specified.
What does a match actually prove?
If two cryptographic hashes (such as SHA-256) match, the underlying files are identical for all practical purposes. For weak checksums like CRC32 or MD5, a match rules out accidental corruption but not deliberate tampering.
