A checksum checks file identity. It is not a malware scan or a security verdict.
GOOD TO KNOW
Questions, answered.
Does my file leave my device?
No. This tool runs inside your browser and does not upload your file or text.
What should I know before using this tool?
Files up to 30 MB. A matching checksum establishes file identity against the supplied hash; it does not prove that a file is safe.
