## What is MelonWallet?

MelonWallet is a privacy-focused PDF book imposition and binding assistant for bookbinders, independent publishers, zine creators, educators, and print enthusiasts.

Turn a PDF in normal reading order into duplex-ready booklet sheets or balanced folded signatures. Your PDFs are processed on your device and are never uploaded.

KEY CAPABILITIES:

1. BOOK IMPOSITION
• Saddle-Stitch Booklets: Arrange sequential pages into two-page sheet sides ready for folding and stapling.
• Folded Signatures: Divide longer documents into balanced signatures with a configurable sheet limit.
• Reading Direction: Prepare both left-to-right and right-to-left documents.

2. PAGE PREPARATION
• Automatic Blank Padding: Add the blank pages required to complete each four-page fold pattern.
• Manual Blank Pages: Insert labeled blanks before or after a page, then edit or remove them at any time.
• Source Inspection: Read the PDF page count and summarize consistent or mixed page dimensions.

3. PAPER & DUPLEX SETUP
• Paper Controls: Choose A3, A4, A5, Letter, Legal, Tabloid, or a custom sheet size.
• Layout Controls: Set margins, gutter, fit or custom scaling, auto-rotation, upscaling, trim marks, and page labels.
• Creep Compensation: Apply a controlled offset for thicker folded booklets.
• Duplex Calibration: Configure automatic or manual duplex output and save printer orientation settings.

4. PREVIEW & PREFLIGHT
• Three Preview Modes: Review physical sheet placement, reading order, or an accessible page list.
• Preflight Checks: Verify file readability, page count, sequence, dimensions, sheet geometry, trim-mark clearance, signature thickness, duplex settings, and cover status.
• Binding Overview: Inspect signatures, sheet sides, automatic blanks, and source-page placement before export.

5. PRODUCTION TOOLS
• Vector PDF Export: Create a complete imposed PDF or separate signature files with an optional binding checklist.
• Cover & Spine Template: Calculate spine width from page count and paper thickness, then generate a printable flat-cover template.
• Offline Toolkit: Create production guides, notebook pages, printer calibration sheets, reusable presets, batch projects, and portable project packages.

PRIVACY & DESIGN PRINCIPLES:
• 100% Offline & Private: Your PDFs, custom settings, and exported documents remain strictly within your device sandbox.
• No Account Required: Instant access on launch with zero mandatory sign-in or registration barriers.
• Pure Utility Focus: No advertising banners, commercial trackers, subscriptions, or locked feature gates.
• Interactive Learning: Includes an instructional starter sample and step-by-step preflight checklist for instant practice.


## Version history (last 2 releases)

### 1.1 — 2026-09-04

What's New in Version 1.1

[CRITICAL HOTFIX] Recommended for all users to update immediately.

• Critical Crash Fix on Large Documents: Resolved a high-priority memory leak issue where importing multi-signature PDF documents (over 64 pages) could cause sudden application termination on iOS 26 devices. • Export Fidelity & Duplex Alignment Fix: Fixed a critical bug in the 2-up signature imposition engine where certain back-page rotation profiles could invert duplex orientation during vector export. • Sandboxed File Integrity: Addressed a severe local cache synchronization glitch that could lead to project package (.melonpkg) loading failures after cold launches. • Calibration Stability: Enhanced core graphic memory allocation during manual printer calibration to prevent rendering freeze.

We strongly recommend all users upgrade to Version 1.1 to ensure project stability and prevent unexpected data loss during print preparation.
