How do I generate MD5, SHA-256, and SHA-1 checksum hashes for media files?

Drop any video, audio, or image file into the Hash Generator. The tool calculates cryptographic hashes (SHA-256, SHA-512, SHA-1, MD5) directly in your browser using the native Web Crypto API.

Why should I verify file checksums after downloading media?

Comparing hashes confirms that downloaded media files are 100% complete and free from corruption or tampering.

Can I compare a calculated hash against an expected hash automatically?

Yes. Paste the expected checksum into the verification box to get an instant green Match or red Mismatch badge.

Are large files (1GB+) supported without crashing the browser?

Yes. The hashing engine streams files in sequential chunks via File.slice() and ArrayBuffer for smooth memory management.

Are files uploaded to any server during hashing?

No. Cryptographic hash calculation executes 100% locally in your browser using hardware-accelerated `crypto.subtle`.

Can I copy generated hashes with one click?

Yes. Click copy buttons to grab uppercase or lowercase SHA-256 / MD5 hashes.

What file types can be hashed?

Any file type (MP4, MKV, MP3, JPG, ISO, ZIP, DMG, EXE) can be verified.
