Merge PDF

Merge PDF is part of Toolspire and is ready as soon as this page loads. Combine several PDFs into one, drag them into the right order and choose exactly which pages to keep from each file. Everything happens on your device — your documents are not sent to us.

What you can do here

Nothing is uploaded

Contracts, bank statements and ID documents stay on your device. The merge runs in this tab tab, so there is no server copy to worry about.

Pick exact pages

Type a range for any file — 1-3, 5, 8- — to leave out covers, blank pages or appendices. Leave it empty to include every page.

Easy reordering

Drag files into place on a computer, use the up and down arrows on a phone, or sort by file name in one click.

Lossless quality

Pages are copied as they are, not re-rendered, so text stays sharp and searchable and images keep their original quality.

Extract pages too

Add one PDF and enter the pages you want to keep to split out chapters, remove pages or change their order.

Free with no limits

No watermark, no file-count cap and no account. Large files are limited only by your device’s memory.

The sequence

How to merge PDF files

  1. 1

    Add your PDFs

    Drag and drop PDF files onto the box or click to browse. Add as many as you need.

  2. 2

    Put them in order

    Drag files up or down, use the arrow buttons, or click Sort by name. The numbers show the final order.

  3. 3

    Choose pages (optional)

    Leave the page box empty to include every page, or type a selection such as 1-3, 5 for that file.

  4. 4

    Merge and download

    Enter a file name and click Merge PDF. The combined file downloads immediately.

Worth knowing

  • Merge PDF on Toolspire: merges PDFs inside your browser with the open-source pdf-lib library — files are not sent to us to a server.
  • Reorder files by dragging, with the arrow buttons, or by sorting them by name.
  • Choose pages per file with ranges such as 1-3, 5, 8-, odd, even or reversed ranges like 6-2.
  • With a single PDF, the same page selection extracts or reorders pages into a new file.
  • Copies pages exactly as they are: text stays selectable, and fonts and images are not re-compressed.
  • No limit on the number of files, no watermark and no account.
  • Password-protected PDFs cannot be merged until the password is removed.

Page selection cheat sheet

Each file has its own page box. Pages are added in the order you type them, and page numbers start at 1.

TypePages included
(empty) or allEvery page
1-3, 5Pages 1, 2, 3 and 5
8-Page 8 to the last page
-4Pages 1 to 4
odd / evenEvery odd or every even page
5-1Pages 5, 4, 3, 2, 1 (reversed)
3, 1, 2Pages 3, 1 and 2 in that order

Why merge PDFs in this tab?

Most PDF websites upload your files to their servers, process them there and keep them for a while before deleting. For tax returns, contracts, medical reports or anything with personal data, that is an unnecessary risk.

This tool uses pdf-lib, a well-established open-source PDF library, running inside your browser tab. Your files are read from your disk, combined in memory and saved straight back to your downloads folder. You can load the page, disconnect from the internet and merge — it still works.

Common uses

  • Job and college applications: combine a CV, cover letter and certificates into the single PDF a portal asks for.
  • Scanned documents: join pages scanned one at a time into one file, in the right order.
  • Invoices and statements: bundle a month of invoices or bank statements for your accountant.
  • Reports: add a cover page or appendix to a report exported from Word or Google Docs.
  • Trimming: keep only the pages you need from a long PDF before emailing it.

Tips for the best result

  • Check the page count shown under each file before merging — it tells you the file was read correctly.
  • If a PDF is password-protected, open it with the password and save a copy without one first.
  • The merged file is roughly the sum of the pages you selected. To make it smaller for email, run it through a PDF compressor afterwards.
  • Form fields and bookmarks from the original files are not guaranteed to carry over; page content always does.

FAQ

Questions about Merge PDF

Where does Merge PDF run?

Merge PDF runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

Is it safe to merge confidential PDFs here?

Yes. The PDFs are processed entirely in this tab and not sent to us, so no copy exists anywhere except on your device.

How many PDFs can I merge at once?

There is no fixed limit. Dozens of files work fine; very large batches are limited only by your device’s memory.

Can I merge only some pages of a PDF?

Yes. Type the pages you want in that file’s page box, for example 1-3, 5 or 8-. Leave the box empty to include every page.

Will merging reduce quality?

No. Pages are copied as they are rather than re-rendered, so text stays selectable and images keep their original resolution.

Can I change the order of pages, not just files?

Yes — pages are added in the order you type them. 3, 1, 2 puts page 3 first. To interleave pages from different files, add the same file more than once with different page selections.

Why can’t I add a password-protected PDF?

Encrypted PDFs cannot be read without their password. Open the file with its password in a PDF reader, save or print a copy without protection, and add that copy.

Does it work on a phone?

Yes. It works in Chrome, Safari, Firefox and Edge on Android and iPhone. Use the arrow buttons to reorder files on a touch screen.

Is there a watermark or a file-size limit?

No watermark, no account and no artificial size limit. The merged PDF contains only your pages.
