Questions about merge pdf

Does merging reduce quality?
No. Pages are copied across as they are, so text stays selectable and images keep their original resolution.
Can I change the order?
Yes. Use the arrows beside each file — they merge top to bottom in the order shown.
How many PDFs can I merge?
As many as your device can hold in memory. Each file can be up to 50 MB.
Will form fields and bookmarks survive merging?
Page content, text and images are copied exactly. Fillable form fields and bookmarks may not, because they belong to the original file rather than to its pages. Fill in and save a form before merging it.
Can I merge PDFs with different page sizes?
Yes. Each page keeps its own size and rotation, so an A4 letter and a landscape receipt can sit in the same file without either being stretched.
