How to fill and sign a PDF form

  1. Add one standard AcroForm PDF and wait for local validation.
  2. Fill the highlighted controls on each page, or use the accessible Field list. Required markers are reminders; you can save an incomplete form.
  3. Generate an editable filled PDF and download it, or explicitly flatten a copy and continue to the visual signature editor.

Values live only in this tab. Text fields, checkboxes, radio buttons and fixed-option dropdowns are supported. Read-only fields stay locked. XFA, scripts, calculations, digital signatures, hidden or nonprinting controls, and additional annotations or links are rejected. Field appearance may change; review the output. Flattening removes field editability, not the ability to alter a PDF. Visual signatures are not cryptographic signatures.

Files stay in this tab's memory. Refreshing or closing the tab loses your work; original files and downloaded copies are unchanged. Browser leave warnings are best effort.

Experimental build: provisional workload limits are enforced, but are not device-tested safety guarantees. Complex files may still exhaust browser memory. Offline use is not promised.
