Frequently asked questions
Can I merge PDFs with different page sizes?
Yes. Pages of any size are preserved exactly as-is in the merged PDF.
Is there a limit on how many PDFs I can merge?
No. Upload as many PDFs as you need and they will all be combined in one operation.
Can I merge JPG and PNG images together?
Yes. When merging into a PDF you can mix any combination of image formats.
What video formats can I combine?
