Description by Obverra Studios Written by the developer, not by AppBrain. Click to read.
InkPDF is a PDF editor that does the everyday jobs well and keeps your documents to itself. There is no account to create, no server to sync with, and nothing ever leaves your device.

SIGN ANYTHING
• Draw your signature once and reuse it on any document
• Signatures are stored as vectors and embedded as real PDF ink annotations, so they render correctly in every reader — not as a pasted screenshot
• Drag and pinch to size it, then drop it exactly on the line

MARK UP AND FILL IN
• Highlight, underline and strike through any selected text
• Draw freehand in four colours, with stroke-by-stroke undo
• Place text anywhere — a date, a name, a note in the margin
• Tap any markup to take it back off the page

MANAGE PAGES
• Reorder by dragging, rotate, delete
• Every edit is undoable until you save

SCAN PAPER
• Use the camera to scan a paper document straight into a PDF
• Scanning is handled entirely on device

YOUR DOCUMENTS STAY YOURS
• No account and no cloud: your documents are never uploaded anywhere
• Nothing you write, draw or scan ever leaves the device
• The only thing that talks to a server is the subscription check
• Edits are written atomically, so an interrupted save can never corrupt a file
• Share or export a copy whenever you want to

Nine languages, full right-to-left support, and it follows your Light and Dark appearance.

INKPDF PRO

Opening and reading a PDF is always free, and so is filling in form fields the document itself provides. The editing tools — signature, text, tick, freehand drawing, highlight, underline, strikeout and page management — are part of InkPDF Pro.

Your first document is free forever. Edit it, keep it, and decide afterwards whether the app is worth paying for.

• A weekly plan, billed every week
• A yearly plan, billed every year

The current price for your region is shown on this App Store page and on the subscription screen in the app, before anything is bought. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of that period. You can manage or cancel your subscription in your Apple Account settings after purchase.
