Calculate a local file hash without uploading it
Choose a file to calculate several checksums on your device. Copy a digest to compare with a published checksum or identify whether two copies are identical.
- Calculate MD5, SHA-1, SHA-256 and SHA-512 digests
- Read the chosen file locally in the browser
- Copy an individual checksum
Choose a file and wait for its digests to appear. Compare the full checksum with a value from a trusted source when checking integrity. A matching hash alone does not establish that a file is safe or trustworthy.
Popular ways to use File Hash / Checksum
- Calculate a file fingerprint before sharing it.
- Compare the digest of a downloaded file with a published checksum.
