A human tip

The useful version of Validate Signature

A conversion tool is most valuable when it removes the work around the conversion. People usually arrive with a destination in mind—an upload, a submission, an email, a report, a website or another editing step. The page should make that destination obvious, keep the interface focused, and offer a sensible next action when the first operation is only part of the job.
