PRIVACY

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

Dynamic XFA forms are not supported.
The PDF.js preview is a visual aid: if the browser cannot render it, inventory and exports remain available.
A field being present does not guarantee its business logic, calculations, or scripts work outside the original PDF viewer.

HOW IT WORKS

A straightforward workflow.

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