What you can do

One app for the whole PDF job

Combine, split, compress and scan — without uploading your documents to a website.

Combine PDFs and photos into one document

Merge multiple PDF files into one — or mix PDFs with JPG, PNG and HEIC photos in the same document. Add files from the Files app, your photo library or the camera, drag pages into order, and save. Merging happens on your device, so it works the same on iPhone, iPad and Mac, even with no internet connection.

Split a PDF into separate pages or files

Split a large PDF into individual pages or several smaller files, or extract just the pages you need as a new document. Choose how many pages go into each file and PDF Combiner does the rest — the original document stays untouched.

Compress a PDF that's too large to email

Reduce PDF file size without uploading the document to a website — compression runs entirely on your iPhone, iPad or Mac, even in airplane mode. Merge several files first, then compress the result to fit email or upload limits.

Scan paper straight to PDF

Capture documents with your camera — edges are detected automatically and pages are saved as a clean PDF you can then merge, split, compress, sign or share. Built-in text recognition (OCR) makes scans and images searchable.

App Store Rating

4.8

Based on 2,300+ ratings across all regions.

Our company doesn't allow free websites to combine PDF files. This app lets me do it without breaking the company's security rules.
— App Store review
Avoid this app if you want the typical free app: ads, nag screens, lousy privacy policy. This app has none of those and is a joy to use.
— App Store review
Works great. Splits very large PDFs fast.

Frequently asked questions

How do I combine PDFs into one on iPhone, iPad or Mac?
Open PDF Combiner, tap Merge, add the PDFs and photos you want to join — from Files, your photo library or the camera — drag them into order, and save. You can mix PDFs with JPG or HEIC images in the same document. It’s the same universal app on iPhone, iPad and Mac, so the steps are identical across your devices.
How do I split a PDF into separate pages or smaller files?
Tap Split, open the PDF, and choose how to divide it — extract individual pages, split into single pages, or break it into smaller files by setting the pages per document. The original stays untouched. To pull out just a few specific pages, use Extract Pages.
How do I compress a PDF on iPhone, iPad or Mac?
Open PDF Combiner, choose Compress PDF, pick the document, and save the smaller copy. Compression runs entirely on your device — the file is never uploaded to a server — and it works without an internet connection.
Can I compress a PDF without uploading it to a website?
Yes. Most popular online PDF compressors upload your file to their servers first. PDF Combiner compresses the PDF on your device instead, so the document never leaves your iPhone, iPad or Mac — you can even compress in airplane mode.
What can I do when a PDF is too large to email?
Use Compress PDF to reduce the file size until it fits your email or upload limit. If you’re sending several documents, merge them into one PDF first and then compress the result — both steps happen in the same app, offline.
Can I reorder, rotate or delete pages in a PDF?
Yes. Edit Pages lets you rearrange, rotate, delete and extract pages, add page numbers, or even out page widths. It reorganizes the pages of a document rather than editing the text inside them.
How do I scan documents to PDF?
Tap Scan and capture each page with your camera — PDF Combiner detects the edges and saves a clean PDF you can then merge, split, sign or share.
Do my files stay private, and does it work offline?
Yes. The tools — merge, split, compress, scan, sign and organize pages — run entirely on your device, so your files are never uploaded to a website and you don’t need any separate computer software. Everything works with no internet connection. The one exception is Office to PDF, where the conversion runs on a server.
What languages does the app support?
PDF Combiner is available in 13 languages — English, Danish, Dutch, French, German, Italian, Japanese, Korean, Malay, Russian, Simplified Chinese, Spanish and Swedish — and automatically follows your device’s language.

No uploads. No waiting.

A fast, private PDF toolkit that works offline, wherever you are.
