Local check
Show the SHA-256 of a file.
Choose one file to read its SHA-256 hash. Choose two files to see whether the hashes match. The check stops at 250 MB per file.
What the hash means
The hash is SHA-256 of the file bytes in this browser.
Two matching hashes mean the same bytes. Two different hashes mean different bytes.
This page does not change the file. A Mirvio variant export makes a new file, and one request stops at 10 variants. A new file does not guarantee reach, approval, or a lower ad cost.
