Generate SHA-256 hashes for text or files and verify checksums against a known value — hex or Base64 output, instant results, fully browser-side.
Generate and verify SHA-256 hashes from text or files
Hash text directly or upload a file.
The generated digest will appear here.
Compare your generated hash with a published checksum.
Compute SHA-256 hashes for text or uploaded/dropped files using the browser's Web Crypto API. Output in hex or Base64, and verify a hash against a known checksum (e.g. from a download page) to confirm file integrity — with a clear match/mismatch result. Everything runs client-side; files and text are never uploaded to a server.
What you get with SHA-256 Hash Generator.
Type or paste text for instant hashing, or drag-and-drop / upload a file up to 100MB.
Paste a known hash to compare against — get a clear match/mismatch result to confirm a download or file wasn't corrupted or altered.
Switch between hexadecimal and Base64 representations of the same hash.
Browser-native hashing — text and files never leave your device.
Follow these steps to get the best results.
Type or paste text for instant hashing, or drag in a file up to 100MB — the hash appears as soon as processing finishes.
Switch output format depending on what your target system expects.
Paste the published checksum into the verify field to get an instant match or mismatch result.

Common questions about SHA-256 Hash Generator.
Switch to File mode, upload or drag in the file to hash it, then paste the published checksum (hex or Base64) into the 'Verify Against Expected Hash' field. You'll get an instant match/mismatch result confirming whether the file is intact and unaltered.
No — SHA-256 is a one-way function. It is computationally infeasible to recover the original input from the hash output.
File integrity verification (checksums), digital signatures, password hashing (combined with salting), and blockchain transactions.
Up to 100MB per file, processed entirely in your browser — the file is never uploaded anywhere.
