Is File Hash Checker free?

Yes, completely free with unlimited file hashing. No registration, no ads, no hidden fees.

What hash algorithms does this tool support?

Supports SHA-256, SHA-1, SHA-512, MD5, and Blake2. SHA-256 is the recommended standard for file verification.

Is my file safe and private?

Yes. All file processing happens directly in your browser using client-side JavaScript. Files never upload to our servers or the internet.

What file size limit does File Hash Checker have?

The tool supports files up to 5GB. Processing speed depends on your device's processing power and file size.

Does this work on mobile devices?

Yes, File Hash Checker works on iPhone, Android, tablets, and desktop browsers including Chrome, Firefox, Safari, and Edge.

Why would I need to hash a file?

File hashing verifies file integrity (detect corruption), confirms authenticity (match publisher hashes), and detects malware or unauthorized modifications.

What is SHA-256 and why is it important?

SHA-256 is a cryptographic hash function that generates a unique 64-character fingerprint for any file. It's the industry standard for security-critical file verification.

Can I compare two files to see if they're identical?

Yes. Hash both files and compare their SHA-256 values. If the hashes match exactly, the files are identical. Different hashes mean files differ.
