About This Tool

Overview

Need to verify file integrity online? This free tool computes SHA-256, SHA-1 and MD5 hashes of any file in your browser and compares them against the official hash. If they match your file is genuine. If not — highlighted in red — the file has been tampered with or corrupted.

What is File Integrity Verification?

Computing a hash of a downloaded file and comparing it against the official hash published by the developer. If both match, the file is authentic and unchanged.

SHA-256 vs SHA-1 vs MD5

  • SHA-256 — most secure, recommended, 64-character output
  • SHA-1 — older standard, 40-character output
  • MD5 — fastest, 32-character output, widely used

Real World Uses

  • Verifying software downloads (VLC, Python, Ubuntu ISO)
  • Validating backup archives before restoring
  • Checking server files for tampering

Privacy First

All hashing runs in your browser. Your file is never uploaded to any server.

What if the hashes do not match?

The file may have been tampered with or corrupted. Delete it and re-download from the official source.

Where do I find the official hash?

Always on the developer's official website, near the download button, labelled "SHA-256", "checksum" or "digest".

Is my file uploaded anywhere?

No. All hashing happens locally in your browser. The file never leaves your device.

What is the difference between SHA-256 and MD5?

SHA-256 is cryptographically stronger with 64-character output. MD5 is faster with 32-character output. For security use SHA-256.
