Question 1

What does flatten PDF mean?

Accepted Answer

A flattened PDF is a document where all layers, annotations, interactive elements such as form fields, and editable features have been combined or merged into a single layer, making it non-editable.

Flattening a PDF removes the ability to modify individual elements or layers within the document, providing a secure and consistent visual display across different platforms and devices.

This is particularly when sharing or printing important files as it preserves the layout, design, and overall appearance of the document. It's important to note that once a PDF is flattened the file becomes a finalized, read-only version.

Question 2

How do you tell if a PDF has been flattened?

Accepted Answer

When a PDF is flattened, it loses the ability to have distinct editable elements or layers, making it appear as a single static image or document.

One easy way to tell if a PDF has been flattened is to attempt selecting and editing text or images within the PDF.

Additionally, check interactive elements like form fields, clickable links, or buttons – these elements will be non-interactive in a flattened PDF.

Question 3

Does flattening a PDF prevent editing?

Accepted Answer

Yes, flattening a PDF prevents further editing of the document. Flattening merges all the visible elements and layers within a PDF into one layer. Once flattened, you can no longer edit individual components like text, images, or annotations.

You can use Xodo’s PDF flattener tool directly in your browser to securely flatten PDF and effectively preserve the original document structure while preventing any unwanted changes.
