Method 1: The Built-In iOS Files App (Quickest for Simple Merges)
If you're running iOS 16 or later, your iPhone can merge PDFs natively through the Files app. No download, no browser, no internet required:
- Open the Files app on your iPhone.
- Navigate to the folder containing your PDFs.
- Tap Select (top right), then tap each PDF you want to combine — in the order you want them merged.
- Tap the More button (three dots) at the bottom right.
- Tap Create PDF.
- A new combined PDF is created in the same folder.
The Files app method merges PDFs in the order you tapped them, but it doesn't let you reorder pages or preview the result before saving. It also doesn't allow you to merge PDFs from different apps (e.g., one from Mail and one from Files) in a single step. For those cases, use the browser method below.
Method 2: Safari Browser Tool (More Control, Still Free)
For merging PDFs from different sources, controlling page order, or combining more than a handful of files, the browser method is more flexible:
- Open Safari on your iPhone and go to rifix.xyz/merge.
- Tap Add Files and select your first PDF from Files, iCloud Drive, or any other location.
- Tap Add Files again to add more PDFs — you can add as many as you need.
- Drag the files in the list to reorder them if needed (long-press and drag).
- Tap Merge PDFs.
- Tap Download — the merged PDF saves to your Files app.
All processing happens in Safari — the PDFs never leave your iPhone. This is important for merging things like bank statements, medical reports, or legal documents.
Where Do PDFs Come From on iPhone?
The most common sources of PDFs you might want to merge:
- Email attachments — Open the PDF in Mail, tap Share, then Save to Files. Repeat for each attachment. Then merge in Safari.
- WhatsApp — Open the PDF in WhatsApp, tap the Share icon, choose Save to Files.
- Safari downloads — Files downloaded in Safari go to your Downloads folder in Files automatically.
- iPhone camera scans — Open Files app, tap the camera icon in the top right to scan directly to PDF. Each scan creates a separate PDF that you can then merge.
- iCloud Drive or Google Drive — Both are accessible from the Files picker when adding files in the Rifix merge tool.
Common iPhone Merging Scenarios
- Visa or immigration application — Passport scan, bank statements, employment letter, and proof of address all as separate PDFs. Merge into one submission file.
- Job application — CV as one PDF, cover letter as another, references as a third. Merge into a single clean document to email.
- Rental application package — ID, payslips, reference letter. Landlords often prefer one attached PDF over multiple files.
- Sending scanned documents — You photograph a multi-page contract on your iPhone (one photo per page), convert to PDF, then merge all pages into a single document. You can convert images to PDF first, then merge.
- Study notes — Combine lecture slides and handwritten notes (scanned) into one revision document.
After Merging: Compressing the Combined File
A merged PDF is often larger than you'd expect — especially when combining scanned pages. After merging, it's worth running the file through Rifix Compress PDF to reduce the size before sending. A 10-page merged scan can easily be 20–40 MB before compression, and 3–5 MB after — the difference between a file that emails fine and one that bounces.
Scan pages with Files app camera → Merge PDFs in Safari → Compress the result → Email or upload. This entire workflow happens on your iPhone without any apps, accounts, or uploads to third-party servers.
Frequently Asked Questions
How many PDFs can I merge at once on iPhone? The browser tool handles as many files as your iPhone's available memory allows. In practice, most people merge 2–10 files without any issues. Very large files (20+ MB each) may be slower on older iPhones.
Can I merge a PDF with images (JPG, PNG)? Yes — first convert your images to PDF using Images to PDF, then merge the resulting PDFs together.
Does it work on iPad? Yes — the same Safari method works on any iPad running iOS/iPadOS 14 or later.
Will the page order be preserved? Yes. Pages within each PDF stay in their original order, and you control the order of the PDFs themselves before merging.
When You Need to Merge PDFs on iPhone
The most common scenario: you have several separate PDF files that belong together and need to be sent or submitted as one document. A multi-document application that includes an ID scan, a proof of address, and a completed form — the receiving system wants one PDF, not three attachments. A client report split across several exports that needs to be one coherent document. Multiple invoices that need to be combined for monthly billing. A photo essay where each image was saved as a separate PDF. Merging solves all of these directly on your iPhone without needing a computer.
Merging PDFs on iPhone Using Safari
Open Safari and go to rifix.xyz/merge. Tap the upload area. On iPhone, the file picker shows your Files app — navigate to the PDFs you want to merge and select the first one. After it appears in the merge list, tap Add More to add subsequent files. Continue until all files are in the list. The order in the list determines the order in the merged PDF — drag items in the list to reorder them if needed. When the order is correct, tap Merge PDFs. The merged document processes on your iPhone without uploading to any server. Tap Download to save the merged PDF to your Files Downloads folder.
Reordering Pages Before Merging
Getting the order right before merging is important — reordering pages after merging requires splitting and re-merging. In the merge interface, drag files in the list to set the document order: the first file in the list becomes the first section of the merged PDF. If you need individual pages from different files in a specific interleaved order — for example, alternating pages from two different scans of a double-sided document — use rifix.xyz/arrange to reorder pages after merging, or use the split tool to extract specific pages before merging.
Merging Scanned Documents on iPhone
iPhone scanning via the Files app, Notes app, or a dedicated scanning app typically produces one PDF per scanning session. If you scan multiple documents separately (scanning one page at a time, or different documents at different times), you end up with multiple PDF files that logically belong together. Merging these is a quick way to create a single clean PDF from multiple scan files. After merging, if the combined document is large (scans at full resolution can be several MB per page), run the merged file through rifix.xyz/compress to reduce size before submitting or sharing.
Merging PDFs from Email Attachments on iPhone
When PDFs arrive as email attachments, save them to your Files app first before merging. In Mail, tap and hold the attachment, then select Save to Files and choose a location. Once all relevant PDFs are saved to Files, go to rifix.xyz/merge and select them for merging. On newer iPhones, you can also drag attachments directly from Mail into the Safari browser tab using Split View — available by holding the browser icon and dragging to the side while keeping the Mail conversation active. This drag-and-drop workflow is faster once you are familiar with it.
What Gets Preserved During Merging
When you merge PDFs at rifix.xyz/merge, the following are preserved in the output: all page content including text, images, graphics, and tables; page dimensions and orientation (portrait pages stay portrait, landscape stay landscape); embedded fonts and their rendering; hyperlinks in the original documents; bookmarks may or may not be preserved depending on how the source PDFs structured them. What is not preserved across the merge: interactive form fields lose their interactivity (they appear as filled values, not editable fields); annotations may merge as flattened content; document metadata (author, title, keywords) defaults to the merged document properties rather than any source document values.
File Size Considerations
A merged PDF is roughly the sum of the sizes of its component files, sometimes slightly smaller due to consolidation of shared resources (fonts used in multiple source files may only be embedded once). If the merged file is too large for your intended use — email attachment limits, portal upload caps, WhatsApp file sharing — compress it at rifix.xyz/compress after merging. Medium compression typically reduces a merged PDF by 40–60% without visible quality loss in standard document content. For merged documents containing high-quality photographs or detailed graphics, use Low compression to preserve image quality while still achieving meaningful size reduction.

Open Merge PDF Tool →Frequently Asked Questions
Can I merge more than two PDFs at once on iPhone?
Yes. The browser-based merge tool lets you add as many PDF files as you need in one session. Tap the upload area multiple times or select multiple files at once from the Files picker. You can then drag the list entries to set the order before merging. There is no built-in limit on the number of files — the practical constraint is the total file size relative to your available browser memory.
Does merging PDFs on iPhone require an account or app?
No. Open Safari, go to rifix.xyz/merge, upload your files, and download the merged result — no account, no sign-up, no app installation. The entire process works in the mobile browser without touching the App Store.
Will the merged PDF be too large to send via email?
Gmail has a 25MB attachment limit; iCloud Mail is 20MB. If your merged PDF exceeds these thresholds, run it through rifix.xyz/compress afterward. Medium compression typically reduces a merged document by 40–60%, bringing most merged PDFs well within email attachment limits.
Can I merge a password-protected PDF with other files on iPhone?
Password-protected PDFs need to be unlocked first. Use rifix.xyz/unlock to remove the password, then include the unlocked file in your merge. Both steps work in Safari on iPhone without any apps.
What is the difference between the iOS Files app merge and the browser tool?
The iOS Files app merge (available by selecting multiple PDFs and choosing "Create PDF") is faster for simple two-file merges, but it re-renders pages as images — losing the searchable text layer. The browser-based tool preserves text, hyperlinks, and font data from the original PDFs, producing a higher-quality merged document that remains searchable and copyable.
Can I reorder pages across the merged documents, not just reorder the files?
Yes. After merging, open the resulting PDF in rifix.xyz/arrange to drag individual pages into any order. This lets you interleave pages from different source documents — for example, alternating pages from two separate one-sided scans of a double-sided original.
