How to Merge PDF Files into One PDF

If a form asks for one file, but your documents are in three separate PDFs, merging them saves you from sending three attachments and hoping the reader opens them in the right order.

Step by step

1. Put your PDF files in one folder on your phone or computer, and rename them in order if the names are confusing, for example 01-ID, 02-Certificate, 03-Form. 2. Open the Merge PDF tool and choose the files in the order you want them. 3. Check the order in the list before you download. 4. Download the merged PDF and open it to check that no page is missing and no file was added twice.

Tips

Do not merge files you do not need, because a long merged file is harder to check and may cross a form's size limit. If a file is password protected, it cannot be merged in a browser tool, and you should not try to unlock someone else's protected file. Keep the original files safe until the merged file is accepted.

Frequently asked questions

Does merging change my text? No, it only puts the pages together in order. Is there a size limit? Very large files can be slow in a browser, so the tool gives a file-size guide. If merging fails, try fewer files at a time. Can I merge a PDF with a photo? Turn the photo into a PDF first with JPG to PDF, then merge the two PDFs.
