How to merge PDF files and review the result on Mac
Combine PDFs into a named packet, replace a revised source, add linked contents and bookmarks, then inspect where the pages meet on Mac.
- What you'll achieve
- You will have a five-page combined packet open in the app, organized into three named sections with linked contents and section bookmarks.
- What you need
- Merge PDF Files Studio for Mac, version 3.0, with permission to read the PDFs you plan to combine.
- At least two readable PDFs. The example uses a two-page program guide, a venue map and a registration form.
- A corrected PDF if you want to practice replacing one section.

Turn separate handouts into an ordered PDF packet in Merge PDF Files Studio. This walkthrough combines a program guide, venue map and registration form, replaces the venue map with an updated file, then builds and reviews the combined packet. The screenshots follow the app's real macOS workflow.
1.Import the PDF documents
Add your PDF handouts to the packet. In Prepare PDF Sections, confirm that all three files are listed with their page counts. Use Add More PDFs… if you need to include another source.

Prepare PDF Sections lists three imported workshop PDFs with the Add Sections (3) action. 2.Name and arrange the sections
Edit the section names in Prepare PDF Sections, then select Add Sections (3). Check that Sections lists Program Guide, Venue Map and Registration Form in the right order. Select a section to preview its source pages.

The sidebar has Program Guide, Venue Map and Registration Form sections beside a page preview. 3.Replace one revised PDF
Select Venue Map in the Sections sidebar and choose to replace its source. In Replace Source, choose the corrected PDF with Choose Replacement PDF…. Confirm the current and new filenames, then select Replace. The section keeps its name and position.

The Replace Source sheet shows the existing Venue Map and a revised PDF ready to replace it. 4.Add contents and preserve bookmarks
Open Output options, turn on Add Linked Contents, and set Source Bookmarks to Keep under section bookmarks. Select Done. These options add a contents page and organize navigation in the combined output.

Output Options shows Add Linked Contents checked and Source Bookmarks kept under section bookmarks. 5.Build and inspect the combined packet
Select Build packet. The Combined Packet view shows the assembled document. Check its section count and page total; in this example, four source pages plus one linked-contents page produce five output pages.

The Combined Packet view previews a revised Venue Map in a five-page PDF document. 6.Review where the PDF sections join
Select Review Boundaries in the combined view. Inspect the last Program Guide page beside the revised Venue Map's first page. Use Next Join and Previous Join to review other section transitions, then select Done. Use Save packet when you are ready to export.

Review Boundaries displays the final Program Guide page next to the revised Venue Map page.
After the last step
You will also inspect a page join side by side before exporting. After closing the join review, use Save packet to save the reviewed PDF.
Tips
Use meaningful section names: they carry through to the section bookmarks in the combined packet.
Replace a revised source instead of deleting and re-adding its section, so the surrounding order and title stay intact.
A linked contents page adds to the output page count. The example has four source pages and five pages in the combined packet.
Review section joins after building the packet, then save the result.
Watch outBuilding and previewing the packet does not save it to a destination. Use Save packet after the review.
Watch outThe replacement changes only the selected section's source within the packet; your original PDF files remain unchanged.
Watch outThis workflow combines whole PDF sources; it does not edit the contents of individual PDF pages.
