Merge PDF Files

How to merge PDF files

1. Drop two or more PDF files into the box, or click to select them. You can add more at any time.
2. Put them in the order you want by dragging the rows or using the arrows.
3. Click Merge PDFs. A single file named merged.pdf downloads immediately.

When to combine PDFs

• Submitting an application that only accepts one file: CV, cover letter and certificates together.
• Sending a client a single invoice pack, or collecting monthly bank statements into one document.
• Joining chapters or scanned sections of a report.

Why merge in your browser?

Many online PDF tools upload your files to their servers. This one does all the work locally with JavaScript, so it is faster for large files and your documents stay private. It is also free with no watermark and no daily limits.

Need the opposite? Split a PDF into parts, rotate pages that were scanned sideways, or turn photos into a PDF with Image to PDF.

What is kept when PDFs are merged?

Pages are copied exactly: text stays selectable and searchable, images keep their resolution, and page sizes and orientations are preserved, so you can mix A4 and Letter pages or portrait and landscape pages in one file. Hyperlinks inside pages keep working. Interactive form fields from several files may conflict if they share the same field names, and document-level bookmarks are not carried over, so check forms after merging.

Merging PDFs on iPhone, Android, Windows and Mac

This tool runs in any modern browser, so there is nothing to install. On a phone, tap “Select PDF files” and pick documents from Files, Google Drive or iCloud Drive; on a computer you can drag files from a folder straight onto the page. Windows and macOS don’t include a simple built-in way to combine PDFs (macOS Preview can, but only with some fiddly dragging), which is why an online tool is often quicker.

Tips for a tidy merged document

• Name files with numbers such as 01-cover.pdf, 02-report.pdf and use Sort A–Z to put them in order instantly.
• Rotate sideways scans first with Rotate PDF so the final file reads correctly.
• Remove unneeded pages with Split PDF before merging, especially blank pages from scanners.
• Check the size limit of the place you are uploading to; merged files are roughly the sum of the originals.

Merging scanned documents

Scanned PDFs are often large because every page is an image. Merging doesn’t change their size, so the combined file can be big. If you hit an upload limit, remove unnecessary pages first with Split PDF, or split the merged result into two parts.
