Your data stays in the browser

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Limitations to know

  • Initial maximum: 50 files and 750 MB combined.
  • The batch only transforms checked categories detected with high confidence; ambiguous business policies must be handled in the single-file tool.
HOW IT WORKS

A straightforward workflow.

  1. 1Prepare the required input and choose useful options.
  2. 2Review previews, warnings and limitations before export.
  3. 3Download a new copy or report: the original stays unchanged.
