How to Correct a Completed Field in an Acrobat Fill & Sign Document
Question details
The user needs to know how to modify or correct a form field that has already been filled out and completed using Adobe Acrobat's Fill & Sign service.

- Product
- Adobe Acrobat Fill & Sign
- Device & OS
- not provided
- Scenario
- Modifying a PDF document after it has been filled out and completed.
- Observed behavior
- Editing a completed field in the Fill & Sign service flattens the form, removing its interactive fields and preventing further standard form-field editing.
Always keep a blank, original copy of your fillable PDF form before signing or saving it as a flattened document. Once a document is digitally signed or flattened, modifying the fields directly becomes restricted.
Use the Original Unflattened PDF File
The best approach is to discard the flattened version and re-enter the data in the original fillable form to maintain a valid workflow.
Acrobat's Fill & Sign service automatically flattens forms once they are completed to prevent unauthorized tampering. Because of this, it is not considered a valid workflow to edit a form after it has been finalized.
To make corrections, you must use the original file before the signature or final save was applied.
Locate and open the original, blank fillable PDF file on your device.
Click on the interactive fields and enter the corrected information from scratch.
Go to 'File' > 'Save As' and save the document with a new name before applying any signatures or using the Fill & Sign flattening feature.

Edit the Text in the Flattened PDF
If the document is flattened but not digitally locked by a certified signature, you can use advanced PDF editing tools to alter the base text.
Fill, Edit, and Sign PDFs seamlessly with WPS PDF
WPS Office includes a powerful PDF editor that makes it incredibly easy to fill out interactive forms, edit existing PDF text, and manage your signatures without losing your work to premature flattening.
- 1. Open WPS PDF: Launch WPS Office and click on 'PDF Edit' to load your fillable PDF form.
- 2. Fill the Form: Select the 'Fill & Sign' or 'Form' tab to interact with the document's text fields, checkboxes, and dropdowns.
- 3. Save as Draft: Enter your information and simply click 'Save' to keep the form editable. Apply your signature only when you are completely ready to finalize.

Frequently Asked Questions
What does it mean when a PDF form is flattened?
Flattening a PDF merges all interactive form fields, annotations, and signatures into the background layer of the document. This removes the fillable fields, making the text permanent and preventing further form-filling edits.
Can I unflatten a PDF to edit the fields again?
No, flattening a PDF is generally a one-way process. Once the interactive form fields are merged into the document's base layer and saved, you cannot revert them back into fillable fields. You must start over with the original blank form.
Why can't I edit my PDF after adding a signature?
Digital signatures are designed to lock the document to ensure its integrity and prove that it hasn't been tampered with since signing. Any changes to the content after signing will automatically invalidate the signature.
How can I save a partially filled PDF form without flattening it?
Instead of using a 'Print to PDF' or final 'Sign' feature, simply go to 'File' and choose 'Save' or 'Save As'. This saves your current progress in the interactive fields so you can close the document and continue editing it later.
