Content placement

Standardizing page sizes changes margins and layout. Content is never stretched. Center Content requires a page large enough to fit. Keep original sizes to preserve non-link annotations.

Document Structure

Preserve Page QualityAlways on. Text, vectors, and images are copied without recompression. Preserve HyperlinksWeb links and internal links to included pages. Internal destinations fit the target page; links to excluded pages are removed. Preserve AnnotationsCopy common page annotations with original page sizes. Widgets become static only after your flattening consent. Catalog-level features are excluded. Create Bookmarks from FilenamesAdd a navigation bookmark at the first output page for each document. Preserve Original Bookmarks / Outlines UnavailableOriginal bookmarks are not retained. Create new bookmarks from filenames instead. Preserve Editable Form Fields UnavailableForms require explicit flattening. XFA forms and layered documents must be exported as ordinary PDFs first. Preserve Compatible MetadataCopy title, author, subject, and keywords from the first document in document order. Manual fields below override them. Remove Nonessential MetadataLeave document metadata empty, including PDF XMP. Manual metadata fields are disabled.

Original signatures, accessibility structure tags, and document-level attachments are not retained. Merge creates a new PDF; keep the originals when these features matter.
