Check the order before merging
Add at least two PDF files. The numbered list shows the merge order and page count for each file. Use Up and Down to move a file, or Remove to leave it out. All pages from the first file come before all pages from the second file, and so on.
You can choose files in several selections. Adding or reordering them clears the previous download, so the result always matches the current list. The source PDFs remain unchanged.
What a combined PDF preserves
Merging copies the pages into one document without turning each page into a JPEG. Pages retain their original sizes and orientations; a landscape appendix can follow a portrait report. Text that was selectable in the source pages generally stays selectable.
Do not rely on this workflow to preserve digital signatures, editable form behavior, document bookmarks or accessibility tagging. Keep the original documents and check the merged copy in a PDF reader. If a signed original must be submitted, follow the recipient’s instructions before combining it.
Limits and alternatives
Each merge accepts 2–20 PDFs with up to 50 MB of source files and 500 pages combined. Password-protected or unreadable PDFs are rejected. A failed file does not remove valid files already in the list. Large or complex documents can still take longer on a phone.
Merging is not a file-size compression tool: the result may remain close to the combined source sizes. To create a PDF from photos, use Images to PDF. To turn pages into image files, use PDF to JPG. For a typed note, Text to PDF creates a searchable document.
