FAQs: Common Questions about Flattening PDFs
What does it mean to "flatten" a PDF?
Flattening a PDF means merging all its interactive elements, such as text fields, checkboxes, and buttons, into the document's base layer. This transforms the file from an editable form into a static, uneditable document.
Can I un-flatten a PDF after it's been flattened?
No, the flattening process is a one-way operation. Once a form is flattened, the interactive fields are gone and cannot be recovered. For this reason, it's always recommended to save a copy of the original, unflattened form before you proceed.
Does flattening a PDF reduce its file size?
Flattening a PDF often, but not always, results in a smaller file size. This is because the process can eliminate the extra data and scripting associated with interactive form fields, which can make the document more compact and easier to share.
