Scope and limits
Hash the actual file bytes locally with SHA-256, SHA-384 or SHA-512. Files are not uploaded or saved to history. Provide a same-format digest to compare, or leave it empty to calculate only. Hex is case-insensitive; Base64 must use standard padding. Matching a digest alone does not establish a trusted publisher or verify a digital signature.

File Hash Verifier
Read a local file in the browser and calculate a SHA-256, SHA-384 or SHA-512 digest from its actual bytes. Choose hexadecimal or Base64 output, optionally enter an expected digest, and compare the values in the same format. The file is processed locally; verify the algorithm and representation before treating a match as evidence of file integrity.
Features
- Read the selected file bytes locally without uploading them.
- Calculate SHA-256, SHA-384 or SHA-512 digests.
- View the digest as hexadecimal or Base64 and compare an expected value.
- Copy or download a report with the file name, size, digest and match result.
How to use
- Select the file you want to verify.
- Choose the SHA algorithm and output format.
- Enter the expected digest in the same format when available.
- Run verification and review or export the report.
