## What is Merge PDF, Split & Unlock?

Merge, split, lock and unlock PDF files — entirely on your iPhone.

Most PDF tools upload your documents to a server and hand them back. This one never does. Contracts, bank statements, ID scans: they are processed on your device and stay there.

KEY FEATURES

• Merge PDF — combine files in the exact order you arrange them. Drag to reorder before exporting.
• Split PDF — separate a document into single pages, or pull out just the range you need.
• Extract pages — keep the pages that matter, drop the rest.
• Lock PDF — set a password, and choose whether printing and copying stay allowed.
• Unlock PDF — remove a password from a file you have the password for.
• Compress PDF — reduce file size so it fits an email attachment.
• OCR — pull editable, searchable text out of a scanned PDF or a photo.
• Watermark — stamp text or an image across your pages, with control over position, rotation and opacity.
• Page numbers — insert numbering anywhere on the page, in the format you pick.
• Extract images — save every picture embedded in a PDF.
• Convert — images to PDF, PDF to images, PDF to Word, Excel to PDF.
• Rotate, annotate, scan and read — the everyday jobs, in one place.

WHY CHOOSE THIS APP

• Your documents are never uploaded. Every PDF tool runs on your device.
• No account and no sign-up.
• Every tool works with no internet connection.
• Your file order is preserved exactly as you arranged it.

WHO IT'S FOR

Office workers merging invoices before sending them to accounting. Students joining lecture files into one. Anyone who needs a PDF job finished in under a minute, on the phone already in their hand.

FREE AND PREMIUM

Reading, annotating, scanning and rearranging pages are free and unlimited. The other tools give you 5 free jobs a day and are supported by ads. Premium removes the ads and the daily limit, and unlocks OCR, watermarks, page numbers, password protection and PDF to Word.

Premium is an auto-renewing subscription. The price and the renewal period are shown before you buy. Payment is charged to your Apple Account at confirmation, and renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings.
