Combine PDFs on iPhone in Safari — no App Store download, no Shortcut setup, no account. Pick files from Files, iCloud Drive, Mail, or Messages; reorder them by dragging the thumbnails; save the combined PDF back to Files. Works on any iPhone with iOS 16 or later.
vastiko.com/merge-pdf/. It is a web page, not an App Store app.Honest comparison — where each option wins on iPhone and where it falls short.
Built in, but images only. Select JPGs in Files, three-dot menu, Create PDF. This bundles pictures into a PDF. It does not merge two existing PDFs. Useful if your "merge" is really "combine a pile of photos into one PDF".
Build a Shortcut using Get File + Combine Images configured for PDFs. Free and local, but takes 10-15 minutes of setup and asks for file permission on every run. Good if you merge daily.
Free app with Combine Files feature, but requires sign-in and uploads files to Adobe Document Cloud. Fine if you already use Adobe for work; heavy for a one-off merge and non-trivial for privacy.
Paid native apps with local PDF merging. Clean UI. Worth it if you handle PDFs every day; not worth buying for one combine.
Free tiers but uploads to their servers. Privacy concerns for sensitive PDFs. Ad-supported in the free tier.
Browser-based, local merge with visual thumbnail reorder. Free, no app install, no signup. PDFs never leave Safari. The right choice when you want a one-shot merge without installing anything.
| iOS version | iOS 16 or newer (works on iOS 15 with slightly slower performance) |
|---|---|
| Browser | Safari (preferred), or Chrome / Edge / Firefox on iOS |
| Storage | ~2× the total PDF size free, temporarily — combining 20 MB of PDFs wants 40 MB free |
| Install needed | None — it is a web page |
| Account needed | None |
| Source files | Files, iCloud Drive, Mail, Messages, Google Drive, Dropbox — any iOS file picker source |
| Max files | Practical ceiling ~30 PDFs totalling 80 MB on iPhone 12 and newer; older iPhones handle fewer |

Open the PDF merger on iPhone
100% private — files never leave Safari.
Yes. Open Safari, go to vastiko.com/merge-pdf/, tap the upload zone, and pick PDFs from Files, iCloud Drive, Mail, or Messages. No App Store install, no account. Works on any iPhone with iOS 16 or later.
Yes — but only for images. Select JPG or PNG files in Files, tap the three-dot menu, and choose Create PDF. This bundles images into a new PDF. It does not merge two existing PDFs. There is no built-in gesture in Files to combine PDFs; you need a Shortcut or a browser tool.
You can build one using the Shortcuts app — actions like Get File, Get PDFs from Input, and Combine Images (configured for PDFs). It takes 10-15 minutes of setup and will ask for file-picker permission each run. For a one-off merge, a web tool is faster: drop the files, drag to reorder, tap Download.
Safari downloads the file to the Files app — by default, the Downloads folder inside iCloud Drive. From there you can AirDrop, email, attach to a Message, or upload to any portal. You can change Safari's download location in Settings > Safari > Downloads.
No. Merging runs in Safari's JavaScript memory using pdf-lib. Your PDFs never leave the device. Close the Safari tab and nothing is retained. This matters for confidential documents where server-side tools introduce a privacy question.
