Merge PDF combines two or more PDF files into one document, with the pages of each file following the previous one. Add your files, check the order in the list, press Merge PDFs and download the combined file. It is the usual last step before uploading an application, sending a set of invoices to your accountant or printing a course pack.
Controlling the order
The merged document follows the list under the upload area, from top to bottom, and every page of each file is included.
- You can add files in several goes; each new file is appended to the end of the list.
- Files cannot be dragged into a new position. To move one, press Remove and add it again so it lands at the end.
- The simplest method is to add files one at a time in the order you want. Renaming them
01-form.pdf,02-id.pdfand so on also makes the list easy to check.
Example: building an application bundle
A portal asks for one PDF containing the filled form (3 pages), an ID proof (1 page), the class 10 marksheet (2 pages) and the class 12 marksheet (2 pages). Add the four files in that order and merge: the result is an 8-page PDF with the form first and the class 12 marksheet last. If the portal wants numbered pages, run the finished file through Add Page Numbers afterwards so the numbering covers the whole bundle.
What carries over and what does not
- Pages are copied intact. Text stays selectable, and images, fonts and page sizes are unchanged. Mixing A4 and Letter files gives a document with both sizes.
- Bookmarks are dropped. The outline or bookmark panel of the source files is not included in the merged file.
- Size adds up. The result is roughly the sum of the inputs, because shared resources such as fonts are not de-duplicated across files.
If the combined file is over an upload limit, try Compress PDF; for scans, shrinking the page images is usually what makes the real difference.
Files that cause trouble
- Password-protected PDFs. Open the file with its password, save an unlocked copy, and merge that copy.
- Damaged files. A PDF that will not open in a viewer will not merge either; re-download or re-export it.
- Very large scans. Everything is held in your device's memory, so hundreds of high-resolution pages may be slow on a phone. Merge in batches, then merge the batches.
- Images. JPG and PNG files cannot be added here directly. Convert them with Image to PDF first, then merge.
Merging happens in the browser tab itself, so contracts and ID proofs are never uploaded.
