How to Merge PDF Files on Phone or Desktop
Last updated
Combining PDFs is one of the most common document operations a small business or student needs. Whether it's scanned receipts going to an accountant, research papers being bundled for a deadline, or a quote being stitched together with its supporting documents, sending one tidy file beats juggling five attachments.
This guide shows how to merge PDFs on your phone using the PDF Editor app for iPhone or Android. The flow is the same on both platforms: import the files, drag them into the order you want, and export one combined PDF. The whole operation usually takes under a minute.
If you'd prefer to merge on a desktop, the principles transfer to most modern PDF tools. The mobile flow is the focus here because it's where most real-world merges happen — between meetings, at customer sites, or in transit.
Step by step
- 1
Open the PDF Editor app
Launch the app and tap the Merge tile on the home screen. No account is required to start.
- 2
Add the files you want to combine
Tap the + button. Import each PDF from Files, iCloud Drive, Google Drive, OneDrive, or by sharing from any other app. You can mix sources freely.
- 3
Reorder the queue
Long-press any item in the queue and drag it to the right position. The order in the queue is the order in the final file. Double-check the sequence before merging.
- 4
Rotate any landscape pages
If some source files were scanned sideways, tap the rotate icon next to each affected item so the merged document reads correctly.
- 5
(Optional) Add a cover page
Tap Add Cover to insert a simple title page with date and a one-line headline. Useful when the merged document is going to a client.
- 6
Tap Merge
The app combines all files into a single PDF and shows the result for review. Merging happens on-device, so even password-protected sources stay private.
- 7
Review the merged file
Scroll through to make sure pages are in order and orientation is correct. Use the Pages thumbnail view to quickly verify.
- 8
Save or share
Save to Files, sync to a cloud drive, or share directly via email, AirDrop, or any messaging app. Pick a descriptive filename — 'Contract-with-Annex-2026-05.pdf' beats 'Document(3).pdf' when the file shows up in someone's inbox.
Tips
- Add a cover page when the merged document goes to an external recipient — it makes the bundle feel intentional rather than improvised.
- Rotate sideways-scanned pages before merging instead of after — fixing orientation later means re-exporting the whole file.
- If the merged PDF is going to be emailed, follow up with the Compress tool so the result fits under typical 25 MB attachment limits.
- Bookmark merged sections via the Pages view so the recipient can jump straight to the relevant part of a longer document.
- Keep the original source files until you've confirmed the merge looks right — never delete the originals from the same session.
Try it on your phone
Mobile merging works particularly well when scans and digital PDFs need to be combined — the app handles both in a single queue, and you can capture a fresh scan on the spot to add to the merge. That's an awkward operation on desktop and a one-tap operation on a phone.
