About File Hash Generator

Berlvis File Hash Generator computes SHA-256, MD5, SHA-1 and SHA-512 checksums for any file you drop in. Hashes are computed locally using the Web Crypto API for SHA variants and the spark-md5 library for MD5, so your file never touches a network. Useful for checking download integrity, comparing two builds, or proving a document hasn't been tampered with.

Frequently asked questions

+Is File Hash Generator really free?

Yes. Every Berlvis tool is free, with no signup, no email and no daily quota.

+Do you upload my files or data?

Never. Your file stays in your browser, nothing is uploaded, nothing is logged, nothing leaves your device.

Yes, anywhere there's a modern browser (Chrome, Safari, Firefox, Edge, Brave, Arc).

+How accurate is the calculation?

We use the same formulas you'd find in official guidance and primary tax/regulatory sources. Numbers are calculated client-side so what you see is what's used, nothing hidden.
