How to merge PDF files
- Add your filesDrop PDFs, JPGs or PNGs onto the page or click to choose them. You can add more at any time.
- Arrange themDrag files into order (or use the arrows), choose which pages to keep from each – like 1-3, 7 – and rotate any that are sideways.
- Merge and downloadName the file, choose bookmarks or duplex padding if you want them, then press Merge PDFs and download the result.
Page range examples
| Type | Includes |
|---|---|
1-3, 5 | Pages 1, 2, 3 and 5 |
2-last | Everything except the first page (handy for removing cover pages) |
last | Only the final page – for example a signature page |
10-1 | Pages 10 to 1 in reverse order |
1, 1, 1 | Page 1 three times |
Tips
- Name files with numbers (01-cover.pdf, 02-report.pdf) and press Sort A–Z to put them in order instantly.
- Merging doesn’t shrink files – run the result through the PDF Compressor if it’s too large to email.
- To send scanned pages as one document, add the JPG photos directly – each becomes a page.
Frequently asked questions
Is it safe to merge confidential PDFs here?
Yes. Files are merged on your device with the open-source pdf-lib library and never uploaded. You can even disconnect from the internet after the page and engine have loaded.
Can I merge only some pages of a PDF?
Yes. Type a page range next to any multi-page PDF – for example 1-3, 5, 8-last. You can also reverse a range (10-1) or repeat pages. Leave it empty to include every page.
Can I combine images and PDFs?
Yes. JPG and PNG images become pages. Choose whether each image page is A4, Letter or the image’s own size in the options.
What are bookmarks?
With bookmarks on, the merged PDF gets an outline entry for each file, named after it. Most PDF readers show these in a sidebar so you can jump straight to each document.
Why add blank pages for double-sided printing?
If a document has an odd number of pages, the next one would start on the back of its last sheet. A blank page after it makes every document start on a fresh sheet.
Do links, forms and annotations survive?
Page content, links and most annotations are kept. Interactive form fields from different files may not work together, and bookmarks from the original files aren’t carried over.
Can I merge password-protected PDFs?
Not directly. Unlock them first with our PDF Password Remover (you’ll need the password), then merge.
Is there a limit on files or size?
There’s no fixed limit – it depends on your device’s memory. Merging dozens of files or several hundred megabytes works on most computers; phones handle less.
