File Hash Checker

Calculate and verify file checksums

About File Hash Checker

Calculate MD5, SHA-1, SHA-256, and SHA-512 checksums for any file directly in your browser — verify download integrity without installing anything.

How to use File Hash Checker

  1. 1Click 'Select file' or drag and drop a file onto the tool.
  2. 2The tool calculates all four hash algorithms (MD5, SHA-1, SHA-256, SHA-512) simultaneously.
  3. 3Click any hash to copy it to your clipboard.
  4. 4To verify a download: paste the expected hash in the verification field and check if it matches.
  5. 5Use 'Compare two files' to check if two files are byte-for-byte identical.

Tips

  • Always verify downloads from the internet using SHA-256 — it protects against corrupted or tampered files.
  • MD5 and SHA-1 are considered weak for security — use SHA-256 or SHA-512 for cryptographic verification.
  • Large files may take a few seconds to hash — the calculation runs entirely in your browser.
