Check File Hash on Windows

Windows has built-in hash commands, but they're complex and error-prone. Check SHA-256, SHA-1, and SHA-512 checksums instantly in your browser — no PowerShell, no Command Prompt, no installation.

How it works

Our browser-based hash calculator uses the Web Crypto API to compute cryptographic hashes entirely on your device. Simply drag and drop any file, and the hash is calculated in seconds. Your file never leaves your computer.

Step-by-step

1. Open this page in any browser on Windows (Chrome, Edge, Firefox)
2. Click the button below to open the File Hash Checker
3. Drag and drop your file or click to browse
4. The tool calculates SHA-256, SHA-1, and SHA-512 simultaneously
5. Compare the calculated hash with the publisher's official hash
6. If they match exactly, your file is authentic and uncorrupted

Supported formats

Works with absolutely any file type: EXE, ZIP, PDF, ISO, images, videos, documents. There is no file size limit since processing happens locally on your device.

Is it safe?

Hash checking is a read-only operation. The tool calculates a fingerprint of your file but does not modify it in any way. Your file remains completely unchanged.

Is this easier than PowerShell on Windows?

Yes. No commands to remember, no terminal to open. Just drag, drop, and compare.

Can I check large files like ISO images?

Yes. Since processing is local, file size is only limited by your device's RAM and patience.

What if the hash doesn't match?

The file has been modified, corrupted, or tampered with. Do not install or open it. Download again from the official source.
