XXH32 Calculator

What is XXH32?

XXH32 is the original 32-bit xxHash algorithm. It produces an 8-digit hexadecimal checksum and is still used by tools and formats that specifically call for a 32-bit xxHash. For newer designs, prefer XXH3 or XXH64.

How to calculate XXH32

Enter text, upload a file, or provide a URL. Optionally set a 32-bit seed, choose Hex or Base64 output, then click Hash. File and URL modes hash raw bytes; text mode uses the selected input encoding.

Seed

Seed is a hexadecimal value of up to 8 digits (00000000–FFFFFFFF). Leave it at 0 unless a protocol or API specifies another value. Enter hex digits only, without a 0x prefix.

Result example

UTF-8 abc with seed 0 produces 32d153ff.
