The "Layer" Problem
Think of a modern PDF like a stack of glass sheets. One layer has your text, another has a signature you just added, and another might have a transparent watermark. This is called layered data.
Flattening is the process of merging all those separate layers into one single "flat" image. Once flattened, your signatures, annotations, and form fields are no longer interactive—they become part of the background.
Top 3 Reasons to Flatten
Permanent Signatures
If you don't flatten a signed PDF, anyone with a basic editor can move, resize, or even delete your signature. Flattening "burns" the signature into the document.
Form Field Integrity
Flattening ensures that your filled-out form data (like tax info or bank details) can't be accidentally edited or wiped by the recipient.
Visual Consistency
Different PDF viewers (phone, browser, tablet) render layers differently. A flattened PDF looks identical on every screen.
Mandatory for Legal & Print
Many government portals and professional printing presses require flattened PDFs. Why?
- Printing: Transparent layers or "overprints" can cause weird boxes or missing elements when processed by physical printers.
- Legal Filings: Courts require documents to be non-editable to prevent tampering after submission.

Wait! Before You Flatten...
- Keep an Original: Flattening is permanent. You cannot "un-flatten" a document to edit the text or signature later. Always keep a backup!
- Check Hyperlinks: Intensive flattening may turn clickable links into static text. Check your links after processing.
