Page numbers start at 1.5-2) is put into ascending order automatically, duplicate page numbers are dropped, and a page number beyond the file's own page count is reported as an error.Most of the time it is because the other side only accepts one file. An expense claim needs the invoice, the itinerary and the approval screenshot in a single document. A tender bundles credentials, track record and pricing in the order of the table of contents. A contract goes out with its annexes and signature pages attached. A journal submission wants the manuscript, figures and supplementary material as one PDF. Another whole category comes from scanning: fronts and backs captured in two passes, or a scanner that starts a new file every few pages, leaving you to reassemble the original order. What all of these need is the right order and unchanged content — not re-layout.
Printing several documents one after another into a virtual printer does produce a PDF, but it is a re-rendered one: the text layer may be flattened into an image, after which nothing can be copied or searched; bookmarks, the outline, hyperlinks and form fields are all lost; and page sizes get normalised to the paper size, shrinking an A3 drawing down to A4. A merge tool moves the original page objects into the new file whole — no redrawing, no re-encoding — so text stays text and the sharpness matches the original.
The documents that need merging are frequently the most sensitive ones you own: scanned ID, bank statements, employment contracts, tender pricing. Most online PDF services upload the file to a server, process it there and send it back — how long it sat on someone else's machine, and whether a copy was kept, is not something you can verify. This page uploads nothing: reading, merging and exporting all happen in your browser, it works with the network disconnected, and closing the tab leaves nothing behind.
Upload a single file, enter the pages you want to keep in its page range (3-5, say), and the export is exactly those pages — extracting by page number is really just a special case of merging. The other trick is adding the same file twice with different page ranges, which lets you reorder sections. If what you actually have is a scan with two pages laid out on each sheet, that is not a page-number problem: first use Split PDF Pages to cut the layout apart.
No. Reading the files, extracting pages, merging and exporting all happen locally in your browser, and the page never uploads your PDF content — so contracts, internal material and unpublished documents are safe here.
Files are joined in list order, top to bottom: the first file's pages come first, then the second file's, and so on. That order starts out as the order you added them; to change it, drag the handle at the left of a row, or use the row's ↑ / ↓ buttons to move it up or down.
On that file's row, switch “Pages” from “All” to “Custom pages” and type the page numbers. Individual pages and ranges can be mixed — for example 1-3,5,8 means pages 1, 2, 3, 5 and 8. Page numbers start at 1 and apply to this file alone; the other files are unaffected.
No. Ranges are always read in ascending order, so 5-2 is the same as 2-5, and duplicate page numbers are dropped as well. Pages within a single file therefore always keep their original sequence — if you need a different order, reorder the files themselves.
There is no size limit, nothing to pay for, no account to create and no plugin to install, and the merged PDF carries no watermark. Tools like iLovePDF and Smallpdf have to upload your files to a server, which is why they must cap file size and free daily conversions; this tool merges inside your own browser, so the server never receives a file and there is nothing to meter. The one real constraint is your device's memory — see the next question.
There is no fixed limit — the real constraint is your device's memory, since every file has to be read into the browser to be processed. A dozen or so ordinary documents merge quickly; if individual files run to hundreds of megabytes, merge them in batches.
No. Whole page objects are copied across into the new document with no re-encoding or rasterising, so the original vector graphics and selectable text survive intact and the result is exactly as sharp as the source.
Page content, images and text are preserved in full, but document-level bookmarks (the table of contents), interactive form fields and some annotations can be lost in the merge. If those structures matter to you, check the result afterwards.
Yes. Such files are usually encrypted with an empty password: they open without you typing anything, but their contents are still encrypted internally. This tool decrypts them automatically before merging, and the page content comes out identical to the original. Only a PDF with a genuine open password cannot be read.
Usually because the file has an open password, or because it is damaged. A password-protected file says so explicitly — remove the protection before adding it. One file failing does not affect the others in the same batch; the rest are still added to the list as normal.
It takes the name of the first file in the list and adds the suffix -merged.pdf — so if the first file is report.pdf, the export is called report-merged.pdf. You are free to rename it once it has downloaded.
