Flattening FAQs

Frequently Asked Questions

1 Why do I need to flatten my PDF?
Flattening ensures your document values, markup notes, stamps, and signatures are merged into the page background. This prevents other people from editing the form values, moving signatures, or deleting comments.
2 Can I make a flattened PDF fillable again?
No. Flattening is a permanent, one-way security mechanism. Once interactive fields are flattened, they are converted into pure visual outlines and the original edit hooks are discarded.
3 Does flattening reduce the quality of embedded text?
Not at all. The text content inside the form fields is converted into standard vector glyphs. Your document retains its razor-sharp layout and is still perfectly readable.
4 What is the difference between forms flattening and annotation flattening?
Forms flattening targets interactive input controls (like text boxes and check buttons) that users can fill out. Annotation flattening locks secondary layers added post-creation, such as highlighted text, sticky notes, and stamps.
5 Does flattening a document make the file size larger?
Usually, it actually reduces the file size because the complex interactive object tree and form metadata are removed, leaving only basic visual assets on the page.
