Combine the report and receipt

Choose the two-page report, then add the one-page receipt. Prepare one PDF and reopen it to check for three pages. Search for BIRCH in the receipt to check that its text is still available in this example.

How to use

  1. Choose PDFs. Add the documents you want to combine. Use Add more PDFs to append another file without starting over.
  2. Check the order. Read the page headings in the previews. Move pages with Earlier or Later, remove unwanted pages and rotate sideways scans if needed.
  3. Save one PDF. Check the total page count and Download name, then choose Prepare download. Save the finished file and check where each source document begins.

Questions

Can I mix pages from different PDFs?

Yes. All imported pages appear in one list, and Add more PDFs appends new ones. Use Earlier and Later or drag pages across documents. The source filename and original page number help you keep track.

Will every checked page be merged?

Merge includes all pages still shown, whether checked or unchecked. Checkboxes are for edits such as rotation or removal. Remove unwanted pages before preparing the download, or use the extraction mode to save only selected pages.

Will text and document features be preserved?

Page text and graphics are copied without turning pages into pictures. The new document may not retain bookmarks, attachments, internal links, document properties or accessibility structure. Interactive forms and signature fields are rejected rather than silently treated as ordinary pages.

What are the limits?

Use up to 500 source pages and 100 MB of source PDFs in one workspace; your device may need a smaller batch. Password-protected documents need an unprotected copy made with permission. Clear workspace releases sources held for undo if you need to start a new batch.

Where does merging happen?

In your browser, without uploading the PDFs to a processing service. The page and processing code can still download over the network. Save the result before closing the workspace; it is not an online document store.

Examples and checks

Add the PDFs you want to combine, then check their page previews. You can move, remove or rotate individual pages before preparing one download.
