Create a flattened version of a PDF
What does flattening a PDF mean?
Flattening generally means reducing interactive or layered page content into a simpler final representation. PDF85’s flattening workflow renders each page and creates a new PDF from the rendered result.
Why flatten a PDF?
Flattening can be helpful when a PDF contains annotations, form appearances or complex elements that may render differently in another viewer. A rendered copy prioritizes the visual page appearance.
Flattening can reduce editability
Because pages are rendered, text and structured objects may no longer behave like the original document. Use flattening when preserving visual appearance is more important than continuing to edit PDF objects.
Use cases for printing and archiving
A flattened copy can be useful for final review, consistent printing or creating a fixed visual snapshot before distribution. Keep the original editable PDF if you may need to make changes later.
How to use Flatten PDF Online

Frequently asked questions
Will flattened text still be selectable?
In PDF85’s rendered flattening workflow, pages are rasterized, so selectable text may no longer be preserved.
Why would I flatten a PDF?
To prioritize stable visual appearance.
Should I delete the original after flattening?
Keep the original if you may need editable or searchable content.
Can flattening change file size?
Yes. Rasterized pages can make the result larger or smaller depending on the source.
Is flattening the same as compressing?
No.
Is flattening the same as removing annotations?
No. Remove Annotations targets annotation objects; flattening renders page appearance.
