Bring it all together.

A proposal, an invoice bundle, or an application packet is easier to review when it arrives as one document. The trick is deciding the reading order before combining anything.

Make a quick document plan

Write down the sequence: cover letter, main document, supporting pages. Rename local files if that helps, but do not assume alphabetical filenames are the order you want. Open each source to check its page count and orientation.

Put the files in order

1. Open Merge PDF.
2. Add at least two PDFs. You can use up to 10 files within a combined 200 MB upload.
3. Use the up and down arrows next to each filename to arrange the list.
4. Select Merge PDF, then download the combined document.

The file list determines the sequence. All pages from the first file come before the pages from the second. To interleave individual pages, merge first and use Organize PDF afterward.

Give the result a proper check

Look at every boundary where one source becomes the next. Those are the most likely places for a duplicate cover, blank page, or backward scan. Compare the final page count with the total of the source documents.

If one source has sideways pages, rotate it before merging. Add continuous page numbers after the order is final, so references remain consistent.

Watch for interactive features

Bookmarks, form fields, and internal links can behave differently after documents are combined. A visible signature image may remain visible, while a cryptographic signature can become invalid when the document changes. Keep the original signed file separately.

Name the final copy for its recipient and purpose. “Application-complete.pdf” is more useful than a series of nearly identical download names.
