About Flatten PDF
Create a rasterized copy of PDF pages when appearance matters more than editable document structure. Flattening is not encryption, redaction or tamper protection.
Important limitations
Rasterizing can remove selectable text, links, forms and accessibility structure. Keep the original. Other software may still copy or alter the resulting pages.
When to use it
Final Forms
Flatten completed forms before sharing.
Prevent Casual Edits
Make a PDF harder to modify in normal editors.
Consistent Viewing
Preserve the visible look of pages across PDF readers.
Questions and answers
Is this the same as password protection?
No. It rasterizes page content. Use Protect PDF if you also need a password.
Can file size increase?
Yes, because pages become images. The backend uses compressed page images to keep output practical.
Choose the operation that matches your document: merging combines files, splitting selects pages, conversion changes formats and compression targets file size. Keep an original copy and inspect the exported document.
