File Hash Verifier
Verify a file against an expected checksum value directly in your browser. Compare SHA-1, SHA-256, SHA-384, and SHA-512 hashes to confirm file integrity before installation, sharing, or archiving.
Upload file
Select the local file you want to verify. Your file stays in your browser and is never uploaded.

Upload a file, select an algorithm, paste an expected checksum, and click Verify Hash.
What does file hash verification do?
File hash verification compares the checksum generated from your local file with a checksum value you already have from a trusted source. If both values match exactly, the file is usually intact and unchanged. If they do not match, the file may be corrupted, incomplete, or different from the expected version.
Why use this online hash verifier?
This tool works fully in your browser, which means your file is not uploaded to a server. It is useful for checking software downloads, installers, backups, archives, and documents.
It also normalizes common checksum input issues like extra spaces, uppercase characters, and prefixed labels so you can paste a checksum and verify it quickly.
Supported algorithms
This browser-based version supports SHA-1, SHA-256, SHA-384, and SHA-512 using the Web Crypto API. These algorithms are commonly used for file integrity verification across software vendors and security workflows.
Common use cases
- • Verify downloaded software before installing it
- • Confirm backup files were copied correctly
- • Compare release packages with vendor-provided checksums
- • Detect corrupted or incomplete file transfers
- • Validate archived files before long-term storage
