About Hash Tools

Hash tools compute cryptographic checksums for files and text entirely in your browser. Verify download integrity, fingerprint duplicates, or prepare hashes for scripts — without sending binaries to a remote hasher.

Best for

  • Verifying installer downloads against published checksums
  • Detecting accidental file corruption
  • Fingerprinting assets in build pipelines
  • Generating SHA-256 digests for documentation

Pros

  • +Local hashing keeps binaries private
  • +Multiple algorithms in one place
  • +Works on files and plain text
  • +Instant results in the browser

Cons

  • −MD5/SHA-1 are not collision-safe for security
  • −Not a password hashing / KDF suite
  • −Huge files still need device I/O time

How to use Hash Tools tools

  1. 1

    Pick the Hash Tools tool you need from the list below — every tool runs locally in your browser.

  2. 2

    Upload your file(s) from your PC, Mac or mobile device, or simply drag and drop them onto the page. You can add more files to process them together.

  3. 3

    Use the gear icon to specify codec, quality, aspect ratio or other settings and apply them to all files if you want.

  4. 4

    Click Convert to start the process. When the conversion finishes, download the result or save it back to Google Drive / Dropbox.

Frequently Asked Questions

Are hash tools free?
Yes. Generate checksums free with no signup.
Do files upload for hashing?
No. Digests are computed locally.
Which algorithm should I use?
Prefer SHA-256 for integrity. Use MD5/SHA-1 only for legacy checks.
Can I hash text?
Yes. Paste text to produce digests without saving a file.
Can I verify a downloaded ISO?
Yes. Hash the file and compare to the publisher checksum.
Is hashing encryption?
No. Hashing creates a fingerprint; it does not encrypt content.
Are results deterministic?
Yes. Same input and algorithm always produce the same digest.
What about HMAC?
These tools focus on plain checksums, not keyed HMAC flows.
