Privacy and local hashing

Updated October 25, 2026.

Your selected content

The hashing feature reads the file you choose in this browser and calculates digests on your device. Text mode works with the UTF-8 bytes of the text field. Selecting content for this feature does not upload it to a hashing server. Results and any exported list can still reveal identifiers for your files, so share them deliberately.

Website requests are separate

Your browser requests the page, scripts and other assets from the website. Hosting and security services can receive technical request data such as an IP address, browser details and requested URL. Local calculation is not a claim that visiting a website creates no network traffic or makes you anonymous.

After a calculation

The calculator keeps its working state in the active page. Refreshing or closing the tab can discard that state. Copy or export the results you need, and store them with the algorithm and source filename. Downloads are managed by your browser and remain on your device until you remove them.

Advertising and cookie choices

This site uses Google AdSense. Google and other advertising partners may use cookies and technical data for advertising, including ads based on previous visits, subject to applicable consent choices.

Shared devices

Remove sensitive input from the page when finished and review your browser’s download and clipboard history. Clearing a page does not delete a file already downloaded or a value copied into another application.
