File Hash
Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes for any file. Batch-friendly, all five at once.
Runs in your browserFree & unlimited
All hashes are computed in your browser. Your files are never uploaded.
About this tool
- 1
Select a file
Drag and drop or click to choose any file from your device for hash calculation.
- 2
Choose hash algorithms
Select one or more algorithms: SHA-256, SHA-512, SHA-1, or MD5 to compute simultaneously.
- 3
View the hashes
See the computed hash values displayed as hexadecimal strings for each selected algorithm.
- 4
Copy or compare
Copy a hash value to your clipboard or paste an expected hash to instantly verify a match.
- Use SHA-256 as your default choice - it is widely supported, secure, and the standard for most integrity verification workflows.
- MD5 and SHA-1 are no longer considered collision-resistant; use them only for non-security purposes like quick deduplication.
- Hash values are deterministic - the same file always produces the same hash, making them perfect for verifying downloads.
- Large files may take a few seconds to hash in the browser; the progress indicator shows computation status.
- SHA-256, SHA-512, SHA-1, and MD5 hash computation in the browser
- Process files of any type and size with streaming hash calculation
- Simultaneous multi-algorithm hashing in a single operation
- One-click copy of hash values in hexadecimal format
- Quick compare field to paste and verify an expected hash
- Verify the integrity of software downloads by comparing hashes against the publisher checksum
- Generate file fingerprints for deduplication in storage systems
- Create hash manifests for digital evidence or legal document archives
- Confirm that a file transfer completed without corruption
SHA-256 for security and integrity verification. MD5 for quick checksums where collision resistance is not critical. SHA-512 for maximum security in sensitive applications.
No. Hash computation runs entirely in your browser using the Web Crypto API. Your file never leaves your device.
Even a single bit difference changes the hash completely. Files may contain invisible metadata, different line endings, or encoding differences that alter the hash.
