FAQ
What does flattening a PDF mean here?
It embeds the current appearances of supported AcroForm fields into the page and removes those interactive fields.
Does it flatten annotations or comments?
No. Comments, highlights, stamps, drawings, and other annotations are outside this tool’s scope.
Can I restore the form fields afterward?
The output no longer contains the flattened form-field structure. Keep the original PDF if you may need to edit or reuse the form.
Does flattening reduce file size?
There is no guaranteed reduction. The output may be smaller or larger; use a separate compression tool if file size matters.
What about digital signatures?
PDFGem does not preserve or validate certificate-based signatures. Re-saving a signed PDF can invalidate its signature; use specialized software.
