Top Quick Tips for Flattening PDF Forms

1. Complete All Fields First

The Tip: Once flattened, forms can’t be edited.

How to Do It: Fill in every field, checkboxes, and dropdowns before flattening. Confirm calculations or auto-filled sections are accurate to avoid locking in incomplete or incorrect data.

2. Save a Backup Copy

The Tip: Flattening is permanent—always keep an editable version.

How to Do It: Store an unflattened copy separately so you can make updates in the future without re-creating the form from scratch.

3. Review Form Calculations

The Tip: Flattening locks results in place.

How to Do It: Double-check that any automatic calculations or dynamic fields (like totals or dates) work correctly before flattening the file.

4. Proofread Before Finalizing

The Tip: Typos and mistakes will be embedded permanently.

How to Do It: Carefully review all text and entries for accuracy. Preview the PDF to ensure all checkboxes, radio buttons, and filled-in sections look correct.

5. Understand the Form Type

The Tip: Flattening behaves differently depending on whether you’re working with XFA or AcroForms.

How to Do It:

• XFA Forms: Flattening dynamic layouts will convert them to static, which may affect appearance or interactivity.
• AcroForms: Typically flatten cleanly, but always confirm all interactive elements appear as intended.

6. Confirm Compatibility Requirements

The Tip: Make sure your flattened file meets recipient or platform needs.

How to Do It: Some portals require static PDFs for upload. Test your file in the intended system to confirm it’s accepted.

7. Use Flattening for Final Versions

The Tip: Only flatten when the document is ready to distribute.

How to Do It: Once flattened, changes are permanent. Apply flattening when submitting, archiving, or sharing the final version of your form.
