Flatten PDF Form Fields

After filling a PDF form, flatten the form fields to lock the values - the recipient can't change them. Useful for KYC forms, expense claims, signed approval forms where field editability would defeat the purpose. The flattened output is a regular PDF (no interactive form anymore).

When to use this

Use to: lock filled forms before sending to bank / KYC team, prevent recipient from editing your filled-in expense claim, finalize signed approval forms, prep filled-in govt-form PDFs for submission portals that reject interactive forms.

Frequently Asked Questions

Will the field values still be visible?

Yes - the values stay visible as regular text. What changes is that recipients can no longer edit / clear the fields. The form looks identical, just locked.
