1. Overview We need a desktop application (Windows & macOS required; Linux optional) that allows users to upload and edit any type of document: PDFs Images (JPG, PNG, TIFF, HEIC, WebP, etc.) Flyers, posters, cards, scanned documents The app must include OCR (Optical Character Recognition) so text in scanned images becomes editable. Users should be able to edit text, replace images, annotate, redact, and export documents. This tool should go beyond existing PDF editors like Sejda by combining: PDF editing Image editing OCR with layout analysis Non-destructive editing layers Advanced export options (PDF/A, PDF/X, CMYK, DOCX, image sets) 2. Goals Provide a desktop-first, offline-capable tool. Universal file import (PDFs, images, SVGs). Enable text and image editing directly in the document. Integrate OCR with multilingual support (English, Arabic, Chinese, Hindi, etc.). Export documents with print-grade quality (CMYK, ICC profiles, bleeds). Ensure performance and usability for large files. 3. Core Features (MVP Scope) 3.1 File Import / Export Import: PDF, PNG, JPG, TIFF, WebP, HEIC, SVG. Export: PDF (Standard, PDF/A, PDF/X), DOCX (basic text export), PNG/JPG, SVG. 3.2 OCR (Optical Character Recognition) OCR for multiple languages. Detects text, tables, and forms. Map recognized text back into editable layers. 3.3 Text Editing Edit existing text directly in PDFs or scans. Add/replace fonts (with fallback). Support for bold, italic, size, color, alignment. Spell check + search/replace. 3.4 Image Editing Replace or insert images. Crop, rotate, resize, deskew. Background removal (basic AI). Noise cleanup and resolution enhancement. 3.5 Layout & Objects Add/remove/reorder pages. Add shapes, lines, annotations. Align, snap, and layer controls. Group/ungroup objects. 3.6 Forms & Annotations Add/edit form fields (text fields, checkboxes, signatures). Comments, highlights, stamps. 3.7 Redaction True secure redaction (content permanently removed). Text and image redaction. 4. Advanced Features (Phase 2+) Batch OCR + conversions. AI helpers (“clean this scan,” “extract table to CSV,” “summarize text”). Plugin system for custom filters & imports. Pre-press features: overprint preview, bleed, preflight checks. 5. Performance Requirements Load a 300-page PDF within 3 seconds. Page render time <500ms. OCR accuracy: ≥98% on clean Latin text, ≥90% for complex scans. Crash-free sessions ≥99.9%. 6. Platform & Technology We are open to the best stack. Options include: Qt/C++ (cross-platform, native performance) .NET (WPF/MAUI) (Windows-first, mac optional) Electron + Rust/C++ modules (fast UI dev, native processing) Mandatory: Auto-update system (signed installers). Offline-first (OCR and editing must not require cloud). Modular architecture for future AI integration. 7. Deliverables MVP (3–4 months): Import/export OCR + editable text layers Text + image editing tools Page management Export to PDF/DOCX Beta Release (6 months): Forms & annotations Redaction Batch OCR Spell check + search/replace Packaging (Windows .exe, Mac .dmg) V1 Release (9–12 months): AI helpers (clean scans, background removal) Advanced export (PDF/A, PDF/X with CMYK) Plugin SDK 8. Success Metrics Users can open, OCR, edit, and export a PDF without leaving the app. Edited text is seamlessly integrated (fonts, flow preserved). Image edits (crop/cleanup) apply non-destructively. Export files open correctly in Adobe Acrobat, MS Word, and print workflows. 9. References Comparable Product: Sejda PDF Editor What We Want Beyond Sejda: OCR integration Mixed image + vector editing True offline-first desktop app Print-grade output

Hi Aafreen H., I recently completed a very similar project. I can show u sample. - For print-grade output: which exact standards? PDF/A-2b or A-3b, PDF/X-4 (live transparency), required ICCs (FOGRA39/51, GRACoL), spot colors and overprint preview? CMYK-only export or color-managed mixed RGB/CMYK with device-link conversions? - Editing/OCR: when a page already has PDF text, do you want true in-stream edits (preserve glyph positions, embed/subset fonts, CID mapping, bidi shaping) or a non-destructive overlay fallback? For scans, prefer paragraph reflow or bbox-accurate text? Priority OCR languages? - Stack suggestion: Qt/C++ core; PDFium for parse/render, Skia GPU tiled renderer (sub-50ms pan/zoom), HarfBuzz+ICU shaping, lcms2 color, libvips/OpenCV for imaging, ONNX Runtime for background removal, Tesseract + PaddleOCR (PP-Structure) for multilingual OCR/table detection Memory-mapped PDFs, page-level worker pool, predictive tile cache to hit 3s load/500ms render Kindly send me a message, lets discuss in detail and my portfolio is uploaded here and on my website. Best Regards, Sid CTO and Co-Founder of Ekarthaan
