1-3, 2,5,9, or 1-3,7,12-14 to take only part of it.0 to put the new pages at the very front.This is the one field people second-guess, so it is worth being precise about. The number you type is the last page of the original document that stays above the inserted block. Everything after it gets pushed down.
Say the destination is a 10-page lease and you are inserting a 2-page addendum:
0 puts the addendum at the very beginning. The lease now starts on page 3.1 slots it in straight after the cover page — a common choice when the addendum is really a summary.5 places it between the old pages 5 and 6.10 appends it to the end, which is the same result you would get from a plain merge.If you are ever unsure, run it once and look at the output. Your original files are untouched, so a second attempt costs nothing but the click.
The page-range box accepts singletons, ranges, and any mix of the two, separated by commas. 4 takes one page. 4-9 takes six. 1,4-6,11 takes five pages from three different places in one pass, and they arrive in the destination in the order you listed them.
That last detail is quietly useful. Typing 3,1,2 inserts page 3 first, then 1, then 2 — so you can reorder while you insert instead of doing it as a separate step afterwards. For a full rearrangement of a document you already have, Reorder Pages gives you drag-and-drop thumbnails, which is easier on the eyes than counting in your head.
Numbers outside the source document's range are simply skipped, so a stray 99 in the list will not stop the job.
Three tools here overlap slightly, and choosing correctly saves you a round trip.
Two documents, and the new material belongs somewhere specific in the middle. A revised clause going back into a contract at page 7. A missing page 4 rejoining a scan. This is the only one of the three that lets you name a position.
Several documents that simply need to be stacked end to end, in a sequence you set by dragging the file cards. Compiling a year of invoices, or gluing a signed cover page onto a proposal. No page arithmetic involved.
One document whose pages are in the wrong sequence. You get a thumbnail grid and drag pages into place. Nothing is added or removed.
And when a page needs to come out rather than go in, Delete Pages takes a range in the same notation this tool uses.
0 and the rest of the document shifts down cleanly.The inserted pages arrive as genuine PDF pages, not pictures of pages. Text stays selectable and searchable, embedded fonts come with them, vector line art stays vector, and images keep their original resolution — nothing is re-rendered or re-compressed on the way in. Page size and rotation travel with each page too, which is why a landscape chart inserted into a portrait report stays landscape instead of being squashed to fit.
Form fields, annotations, and page-level links are carried over by the same page-copying step. Document-level furniture is a different matter: the bookmark tree and the outline belong to the file as a whole rather than to any single page, so the output gets the destination document's structure. If bookmarks matter for the finished piece, add them at the end once the page order is final.
Printed page numbers are ink on the page, so they say whatever they said before. Add Page Numbers stamps a fresh, correct sequence across the whole document in one pass — the usual last step after any insert.
Each run places one block of pages at one position, which keeps the result predictable. For several insertion points, run the tool once per position — the output of one run becomes the destination of the next. Work from the last position backwards (insert after page 20, then after page 9, then after page 2) and the earlier page numbers stay valid the whole way through, so you never have to recalculate.
Yes — 1-3,7,12-14 is valid and takes eight pages. Spaces are ignored, so 1 - 3, 7 works the same way. Pages arrive in the order you typed them, which doubles as a quick reordering trick.
Yes. Load the same PDF into both slots and you get a duplicate-and-place operation — handy for repeating a terms page behind every section, or cloning a template page you are about to fill in differently.
Those numbers are part of the page content, so they carry across exactly as they were. Run Add Page Numbers over the finished document for a correct sequence — it can skip a cover page and start counting where you want it to.
Each page keeps its own size, so an A4 document can absorb a Letter page or a landscape chart without either being stretched. Most viewers and printers handle mixed-size documents fine. If you would rather everything matched, Crop PDF trims pages to a consistent box before or after the insert.
Unlock it first with Protect PDF, which removes the password when you supply it, then insert. You can put the password back on the finished document with the same tool once the pages are in place.
The ceiling is your device's memory rather than any limit we impose. Documents in the hundreds of pages are routine on a laptop, and a mid-range phone handles typical office files comfortably. Very large scanned files go faster if you run Compress PDF over them first.
No. Both PDFs are read and combined by JavaScript running in this tab, and the finished file is handed straight to your browser's downloads. You can disconnect from the network before you start and the tool still works — a reasonable thing to try if the documents are confidential.
Privacy: Both PDFs are held in memory inside your browser. pdf-lib does the splicing locally — nothing about either file is uploaded anywhere.
