Merge PDF
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 never uploaded.
At a glance
- Merges PDFs inside your browser with the open-source pdf-lib library — files are never uploaded 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,evenor reversed ranges like6-2. - 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 sign-up.
- Password-protected PDFs cannot be merged until the password is removed.

- 2

- 3

Leave the page box empty to include every page, or type a selection such as

Merge and download
Enter a file name and click Merge PDF. The combined file downloads immediately.
Features
Everything you need, nothing you don’t
Nothing is uploaded
Contracts, bank statements and ID documents stay on your device. The merge runs in your browser 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.
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.
| Type | Pages included |
|---|---|
(empty) or all | Every page |
1-3, 5 | Pages 1, 2, 3 and 5 |
8- | Page 8 to the last page |
-4 | Pages 1 to 4 |
odd / even | Every odd or every even page |
5-1 | Pages 5, 4, 3, 2, 1 (reversed) |
3, 1, 2 | Pages 3, 1 and 2 in that order |
Why merge PDFs in your browser?
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.
