* Your file is processed entirely in your browser and never sent anywhere.
Calculate a hash (SHA-1, SHA-256, SHA-384, or SHA-512) for a local file. Compare it against the hash published by the file's source to verify a download hasn't been corrupted or tampered with. Your file is processed entirely in your browser and never sent anywhere.
How to use
- Drag and drop the file you want to check, or click to select it.
- Choose a hash algorithm (SHA-1, SHA-256, SHA-384, or SHA-512).
- Paste the expected hash published by the source into the "Expected hash" field to automatically check whether it matches.
FAQ
Is my file uploaded to a server?
No โ the hash is calculated entirely in your browser using the Web Crypto API; the file's contents are never sent anywhere.
Does this support MD5?
No โ since the browser's standard Web Crypto API doesn't support MD5, this tool only supports SHA-1, SHA-256, SHA-384, and SHA-512.
Can this handle very large files?
Yes, though very large files (multi-gigabyte) will use more browser memory and take longer to process.
