Compute SHA-256, SHA-384, SHA-512, or SHA-1 checksums for any file in your browser.

Processing: in your browser (nothing uploaded)

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

File Hash / Checksum runs entirely in your browser on FileToolsHub. Your file is processed in this tab and is never uploaded to our servers.

That means passwords, tokens, personal notes, and documents you paste or load stay on your device. Clear the page or close the tab when you are finished on a shared computer.

You still need a network connection to load the page the first time. After that, the core processing for File Hash / Checksum does not require sending your content to FileToolsHub.

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.
  • File Hash / Checksum does one focused job. For multi-step workflows, use the related tools below or the Text Tools hub.
