HASHME makes it easy to check.
Your free, offline SHA-256 file hasher. Drop a file and get its complete checksum, right in your browser. HASHME never uploads or changes your file.

01 / THE WORKFLOW
Just your files and their SHA-256 fingerprints, calculated on your own machine.
Drag one file or several into the HASHME box above. On a phone, tap to choose your files. Nothing is uploaded.
HASHME reads each file in small chunks and calculates its SHA-256 hash on your device. Follow the progress as it works.
Copy a complete 64-character hash, or copy all results with their filenames. Clear the panel when you’re finished.
SHA-256, WITHOUT THE JARGON
SHA-256 reads the contents of a file and runs them through a fixed set of mathematical steps. The result is a 256-bit fingerprint, displayed as 64 letters and numbers. The same contents always produce the same hash; even a tiny edit produces a very different-looking result. HASHME reads your file to calculate that fingerprint. It does not change the file or embed anything inside it.
Why use it? Compare a download with a hash published by a trusted source, or compare an original with a backup. Matching hashes give strong evidence that the contents match; different hashes show something changed. A hash checks integrity—it is not encryption, a virus scan or proof of who made the file.

HASHME reads your file locally and calculates its SHA-256 fingerprint on your device. It does not upload your file or send filenames and results to a HASHME server. It does not write hashes, tags or metadata into the original file. Results live in this page’s memory; clearing the panel or reloading removes them.
Yes. Open this page while online and wait for OFFLINE READY beneath the HASHME box. Then disconnect and keep the page open: selecting files, hashing, copying results, clearing and starting again all work locally. Reopening or refreshing the website needs a connection. The Windows desktop app runs offline after installation.
A SHA-256 hash is a 64-character fingerprint of a file’s contents. You can compare it with a trusted published hash or with the hash of another copy to check integrity. Renaming a file does not change its hash. A hash is not encryption and does not establish whether a file is safe to run.
Yes. HASHME v1.2 for Windows 11+ x64 adds a floating desktop strip, local verification records, Pair Match, .sha256 sidecars and SHA256SUMS manifests. Changed baselines require explicit approval before replacement.
The browser edition above generates SHA-256 fingerprints. The desktop version provides the catalogue and verification features. Check the desktop release details.
