InkIt Pro is the complete offline document workstation: sign, annotate, build, fill forms, sanitize, crop, and organize your files in one lightning-fast, privacy-first desktop app. Built natively for Windows with a high-performance Rust core, designed for professionals, researchers, students, and businesses that demand uncompromising privacy, zero cloud uploads, and extreme speed. Tired of uploading confidential contracts, financial spreadsheets, medical records, or personal IDs to untrusted online converters? With InkIt Pro, 100% of the processing happens locally on your computer. Your files never touch external servers or the cloud. ? SEAMLESS PROCESS CHAINING & ROUNDTRIP WORKFLOW Forget saving intermediate files to your desktop just to move them to another tool. InkIt Pro introduces true non-destructive tool chaining: • Universal Tool Chaining: Edit and sign a document in F1, send the result directly to Quick Merge (F5) with one click, split it in F6, or apply watermarks in F7 without leaving the flow. • In-Place Board Roundtrip: From the Page Organizer (F2), select any specific pages (or the entire document), send them to any specialized tool (like Smart Crop, Watermark, or Doctor), and inject the processed pages right back into their exact positions on the board in the very same session. Zero lost progress, zero file clutter. ? 15+ FORMATS ON A SINGLE CANVAS (NOT JUST PDF!) InkIt Pro is much more than a PDF reader. It is a universal document compositor that ingests over 15 file formats natively: • Documents & Office: PDFs (.pdf), Microsoft Word (.docx, .doc). • Spreadsheets & Data: Microsoft Excel (.xlsx, .xls), CSV (.csv), JSON (.json). • Notes & Code: Markdown (.md), Plain Text (.txt, .log). • High-Resolution Media: PNG, JPG, JPEG, WebP, BMP, GIF, TIFF (.tiff, .tif). Drag and drop any mixed cocktail of documents and photos onto the board; InkIt Pro automatically converts them into crisp, interactive pages ready to reorder, annotate, sign, and export as a single cohesive PDF. ?️ ADVANCED SIGNING, INKING & ACROFORMS (F1) • Interactive AcroForms: Click and fill interactive form fields directly on your pages. Choose between flattening forms permanently upon export or keeping them editable for other users. • Freehand Pencil & Inking: Draw, underline, circle, or write spontaneously with smooth, pressure-sensitive freehand strokes and adjustable widths. • Signature Vault & Bilingual e-Signs: Draw and save your signature once to stamp it anywhere with a click. Create formal digital stamps with legal timestamps in English and Spanish. • Smart Typewriter & Stamps: Click anywhere to type custom notes with full accent/symbol support. Stamp quick checkmarks (✓), crosses (✗), or current dates. • Permanent Redaction: Blackout or whiteout sensitive data (SSNs, banking details) permanently from the underlying PDF stream before sharing. • Dark Mode PDF Export: Invert colors into an eye-friendly dark mode for OLED screens while keeping text 100% sharp and vectorial. ? INTERACTIVE PAGE ORGANIZER (F2) • Visual Board: Rearrange, duplicate, rotate 90°, delete, or invert page sequences with drag-and-drop ease. • Surgical Extraction & Merge: Pull exact pages from a 500-page manual, combine them with photo receipts, and compile a clean dossier. • Professional Separators: Insert centered cover pages and section dividers to organize merged files like a published book. ?️ THE DEDICATED TOOLBOX SUITE (F3 – F12) • PDF Doctor & Sanitizer (F10): Repair corrupted XRef tables, prune orphan objects, strip tracking metadata (XMP authors/edit history), and neutralize malicious embedded JavaScript. • Smart Crop & Book Split (F4): Trim margins in batch and automatically slice dual-page book scans into single sequential pages. • Watermarking & Bates Numbering (F7 & F8): Stamp custom text or transparent company logos at any angle, and apply professional automated page numbers. • Continuous Long Strip (F9): Assemble multi-page PDFs and screenshots into one seamless vertical scrolling image (PNG)—ideal for webtoons and infographics. • High-Efficiency Compression (F3): Shrink heavy PDFs with native lossless or downsampling algorithms for easy email sharing. • High-Res Image Extraction (F12): Extract pages as high-resolution PNGs or batch-package them into a clean ZIP archive. • Text & Markdown Extraction (F11): Pull pure readable text from complex documents for instant quotes and notes. ?
