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.
+Will it work on my phone?
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.
