PDFcraft

A fast, fully client-side PDF editor that runs in the browser. Upload PDFs, reorder/rotate/delete pages, merge multiple files, add styled text and QR codes, then export a new PDF — all without a server. Your files never leave your device.

Features

• Upload & merge multiple PDFs (drag-and-drop or file picker)
• Page management — reorder (drag), rotate, and delete pages
• Text annotations — click to place; edit content inline (double-click)
  • Font family, size, color, bold / italic / underline
  • Alignment, line height, opacity, and highlight color
  • Auto-sizing boxes (no wrapping — Shift+Enter for a new line)
• QR codes — place, edit the encoded URL/text, recolor, and resize
• Zoom, undo / redo, and one-click Export PDF

Tech stack

• React 19 + TypeScript + Vite
• PDF.js — render PDF pages to canvas
• Konva / react-konva — interactive annotation layer
• pdf-lib — write the exported PDF
• zustand — state, @dnd-kit — drag-and-drop, qrcode — QR generation
