File Hash Calculator
File Hash Calculator is a free online tool for computing file checksums with six algorithms: MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. Drag and drop or select multiple files for batch calculation — large files are read in chunks with a live progress bar, and every result can be copied with one click.
Files are read and hashed entirely in your browser and are never uploaded to any server; the tool is free and requires no sign-up. Use it to verify download integrity, detect file tampering, or generate checksums for release packages.
How to Use
- Select the hash algorithms you need (e.g., MD5, SHA-256 — multiple allowed)
- Drag files into the drop zone, or click to choose one or more files
- Wait for calculation to finish — large files show live progress
- Click the copy button next to each hash value
FAQ
Is this file hash calculator free?
Yes, it is completely free with no registration required and no limit on the number of files.
Are my files uploaded to a server?
No. Files are read and hashed entirely in your browser using chunked reading — no data ever leaves your device, so confidential files are safe.
Which hash algorithms are supported?
MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. You can select several algorithms at once and compute them in a single pass.
Can it handle large files?
Yes. Files are processed in chunks rather than loaded into memory all at once, and a live progress bar tracks the calculation, so large files complete reliably.
