When a document should stop being editable.
Annotations and form fields are separate objects layered over the page. That is what makes them useful while you work: they can be moved, restyled, answered and deleted. It is also what makes them a liability once the document is finished, because the recipient can move, restyle and delete them too, and because some readers render annotations differently or hide them entirely.
Flattening merges those layers into the page itself. A signature can no longer be dragged off the line, a filled form can no longer be altered, a highlight cannot be deleted, and every reader shows the same thing because there is nothing left to interpret. It is the right last step before sending a signed agreement, archiving a reviewed draft or printing a completed form.
It applies only to the downloaded copy. Your working document in the editor keeps its annotations and fields, so you can flatten a copy to send and carry on editing the live version afterwards.
Questions about this tool.
The things worth knowing before you edit the document.
Can a flattened PDF be un-flattened?
No. Once annotations are merged into the page there is no separate object to restore, which is the point. Keep an unflattened copy if you might need to edit the markup later.
Does flattening lock the form fields?
Yes. Field values become part of the page, so the answers can be read and printed but no longer changed. That is usually what you want before sending a completed form on.
Will my highlights look the same in every reader?
That is the main reason to flatten. Readers vary in how they draw annotations, and some hide them by default. Flattened markup is page content, so it renders identically everywhere.
Does flattening change my working document?
No. It is applied to the exported copy only. The document in the editor keeps its annotations and interactive fields.
