PDF MarkX - Read, Edit & Sign

PDF MarkX is a full-featured PDF editor that works entirely offline. No subscription, no account, no cloud required — pay once and own it forever. ANNOTATE Highlight, underline and strikethrough text in any colour. Everything renders into the PDF permanently when you save, so your markups always travel with the document. SIGN Draw, type or photograph your signature once and save it for reuse. Place it on any page with a tap, then drag, pinch-to-resize, rotate or flip to fit exactly where you need it. DRAW Write notes, sketch diagrams and mark up pages with Apple's PencilKit tools — pen, highlighter and eraser with full colour control. ADD TEXT Drop a text box anywhere on the page — useful for filling forms, adding dates, or leaving notes. Save phrases you use often as presets and reuse them across documents. NAVIGATE Jump to any page with the navigation bar at the bottom of the editor. Tap the page number to type a destination directly — no scrolling through hundreds of pages. MANAGE PAGES Reorder, delete and split pages from inside the app. Use the scissors tool to export from any page onwards as a separate PDF. MERGE Combine multiple PDFs into a single document in seconds, ready to save or share. NO SUBSCRIPTION PDF MarkX is a one-time purchase. Pay once, use on any device you own, with no recurring fees and no feature locks.
