About File Hash / Checksum

File Hash Checker computes SHA-256, SHA-384, SHA-512, or SHA-1 checksums for any file in your browser.

Use it to verify downloads, compare builds, or confirm a file was not altered in transit.

Choose an algorithm, drop the file, and copy the hex digest.

Hashing uses Web Crypto on your device — the file is never uploaded.

How to use File Hash / Checksum

  1. 1

    Choose a hash algorithm.

  2. 2

    Drop or select a file.

  3. 3

    Copy the hex digest.

Why use File Hash / Checksum

  • Browser-only Web Crypto
  • No upload
  • Multiple algorithms
  • Private

Use cases

  • Verify a download matches a published SHA-256 checksum
  • Compare two builds with SHA-512 digests
  • Confirm a file was not altered in transit
  • Hash sensitive binaries locally without uploading

Privacy

Runs entirely in your browser — your file is not uploaded.

Limitations

  • File Hash / Checksum depends on your browser. Very large inputs may slow or freeze older devices; try a smaller sample if the tab becomes unresponsive.

Which algorithms are supported?

SHA-256, SHA-384, SHA-512, and SHA-1 via Web Crypto. MD5 is not included.

Is the file uploaded?

No. Hashing stays on your device.

MD5?

Not included — modern browsers expose SHA via Web Crypto. Use SHA-256 for integrity checks.
