Security tool
SHA-256 hash of any file in-browser.
File Hash computes a SHA-256 digest of any file you select—entirely in the browser with the Web Crypto API. Use it to verify downloads, compare builds, or fingerprint artifacts without uploading the file to a remote checksum service.
Publishers and package mirrors often list a SHA-256 checksum next to a download. Computing the same digest on your machine confirms the file you received matches the published fingerprint (within the limits of trusting that published value). This tool reads the file with the File API, digests it with crypto.subtle.digest("SHA-256"), and shows a hex string—no server upload of file contents for hashing.
SHA-256 is a widely supported standard for integrity checks. It is not encryption: anyone with the file can compute the same hash. It also does not prove who published the file unless combined with signatures or a trusted channel. For large files, hashing may take a moment and uses local CPU and memory; keep other heavy tabs closed if the browser feels sluggish.
As with any security utility on the web: prefer local processing for confidential binaries, and avoid uploading regulated or highly sensitive files to third-party sites when your policy requires offline tools. This page is designed so the hash runs client-side; still treat the browser environment and extensions as part of your threat model.

Use the file picker to select an archive, installer, image, or any other file. The bytes are read locally in your browser.
The tool digests the full file with SHA-256 via Web Crypto. Larger files take longer; progress depends on device performance.
Copy the lowercase hex hash and match it against the publisher’s published checksum or your previous fingerprint.
Confirm an installer or archive matches the SHA-256 checksum listed on the vendor’s site.
Ensure two copies of a binary or release tarball are byte-identical across machines.
Re-hash a file after transfer over USB or cloud sync and spot bit-flips or incomplete copies.
Record a SHA-256 of a document snapshot for change-detection workflows (not a legal substitute for proper chain-of-custody tools).
Tip: after you finish, check Related tools at the bottom of this page for the next step in your workflow.
Quick answers about tools, privacy, limits, and pricing.
No. SHA-256 is computed in your browser from the file’s local bytes. The file contents are not uploaded for hashing.
SHA-256 only on this page, via the Web Crypto API. For text multi-algo digests, use Hash Generator.
No. A matching hash only shows the file matches a given fingerprint. It does not prove the publisher is trustworthy or that the software is malware-free.
The entire file is read and digested in the browser. Very large files stress memory and CPU; try a desktop browser and free up RAM if needed.
Processing is local, which is better than unknown upload-based checkers. For highly sensitive material, offline native tools under your organization’s control may still be required.
Yes. File Hash is free to use on ezToolFlow. Guests and free accounts may have daily limits on some tools; premium tiers can raise or remove those limits. AI tools may also spend credits.
For browser-based tools, processing runs on your device when possible and files are not uploaded for conversion. Optional accounts, usage limits, and AI features are described in our Privacy Policy.
No for most tools — you can start as a guest. An account helps keep higher daily limits and saved work (for example AI resumes).
Close other heavy tabs, use a smaller input file, and try Chrome or Edge on desktop. Very large files can stress browser memory.
Yes, the page is responsive. Complex media or large PDFs still work better on desktop because of memory and CPU limits on phones.
Keep working with similar free tools — no signup required for most.
