How to Flatten a PDF Form Before Emailing
Prevent form fields from being edited after submission by flattening before emailing. Free, quick.
A fillable PDF form emailed without flattening can be edited by the recipient. Flatten it first to lock in your responses.
Steps
Complete the form. Go to fixmypdf.in/tools/flatten-pdf. Upload the completed form. Flatten. Attach the flattened PDF to your email.
Why This Matters
Some email clients and PDF viewers don't display form fields correctly. Flattening ensures your responses are visible to everyone, regardless of their PDF software.
