Compare two digests character by character and see exactly where they stop matching.

Whitespace and line breaks are ignored, and both values stay inside your browser.

Common questions about the free online hash comparison.

Paste one digest in each box. The verdict line says whether they are identical, and the marker line shows every position that differs.

No, by default. Hexadecimal digests mean the same thing in upper or lower case, so both are normalised before the comparison.

Different algorithms produce different sizes, and a truncated or pasted fragment is shorter. The length line shows both counts so you can spot that.

A dot means the two characters at that position are equal and a caret marks a mismatch, which makes a single wrong character easy to find.

You can compare any text, but this tool is meant for digests and checksums. Use a password strength checker for passwords instead.

For checksums it is fine. Servers that compare secret tokens should use a constant time comparison to avoid leaking timing information.

No. Both values are compared in your browser with plain JavaScript and are never transmitted or stored.

Yes. It is completely free, works offline once loaded, and needs no account, no sign-up and no installation.
