Actual widget output
Downloads people can trust

Let visitors check a downloaded file matches yours.

Each example below is the actual published output of the Local file checksum widget, set up with the SHA-256 of a sample PDF of watercolour practice sheets. Choose any file to see its checksum; it is read on your device and never uploaded.

Your file stays on this device. A matching checksum shows the file is identical to the one the checksum was taken from; it does not prove the file is safe or who made it.

Default button with the expected SHA-256 of the sample PDF set, so a chosen file is reported as matching or not.
