Check these details in the result
- Check repeated field values and checkboxes
- Check small text at normal viewing size
- Keep the original for comparison
Finish the form before fixing its appearance
Use this step after the final content correction. Check names, dates and selected checkboxes in the original form. Once flattened, the previous input fields are gone. Further corrections require the editable source or another editing method. Keep a completed editable version as well if you expect to prepare revised copies later.
Appearance and interactivity are different
The output incorporates the visible appearance into page content. Form actions, separately editable annotations and their comment metadata are lost. The result does not guarantee protection from further PDF editing and does not replace a digital signature. Open the new file in a PDF viewer to check long entries, unusual fonts and any appearance that matters to the recipient.
Frequently asked questions
Will completed values remain visible?
Their visible appearance is flattened into the pages. Still check every important field in the result.
Can I fill in the flattened form again?
Its original interactive fields are no longer available. Use a saved editable version for that purpose.
