PDF form answers disappear after saving?

Short answer. Usually the viewer saved the values in one layer and the next viewer shows another (XFA vs AcroForm), or the fields have no drawn appearance. Fill the form with a tool that writes appearances, then flatten a final copy.

Causes and fixes

  1. 1
    Hybrid XFA form opened in different viewersAcrobat shows the XFA layer; browsers show the AcroForm layer. Values saved in one may not appear in the other.
    Check for XFA
  2. 2
    Fields without appearance streamsIf a value is stored but its appearance isn’t drawn, some viewers show an empty box until you click it.
    Fill with appearances
  3. 3
    Saved with “Print to PDF” or a viewer that drops form dataSome save paths keep the page but not the form values.
    Flatten a final copy

What is going on

A filled PDF form holds each answer twice: as a value attached to the field, and as an “appearance”, a small drawing of that value inside the box. Viewers that only read appearances show what was drawn; viewers that redraw from values show the value. When the two disagree, or when only one exists, answers seem to vanish.

Hybrid government forms add a third copy: the XFA data. Adobe Acrobat and Reader display the XFA form, while Chrome, Edge, Firefox and Preview display the AcroForm fields. Type in one and open in the other, and the answers can look lost even though they are in the file. People filing immigration forms report exactly this when they reopen a saved form.

The dependable fix is to fill in one consistent way and keep a flattened copy. Filling here writes the value and draws its appearance for every field, and flattening turns those appearances into ordinary page content, so every viewer and every upload portal shows the same thing. Keep an unflattened copy too, in case you need to change an answer. For official forms, check the agency’s instructions about which software to use [1].
