主要功能

• 鼠鼠原版界面：鼠鼠会跟随上传、识别、批量、OCR、转换成功或失败切换状态。
• 本地离线转换：内置 FFmpeg、LibreOffice、Poppler、Tesseract 和 AVS3 解码器。
• 支持图片、文本、Word/WPS、Excel/WPS、PPT/WPS、PDF、音频、视频和 ZIP。
• NCM 解密与转码：支持来自 music.163.com 对应网易云音乐客户端的常规 NCM，以及 Audio Vivid（AV3A）NCM。
• mflac/mgg 解密：支持 QQ 音乐官方客户端下载的 mflac/mgg（新版 musicex 需 QQ 音乐登录凭据在线换密钥；原档无权限时自动降档下载同一首歌的可用音质档位）。
• 操作记忆：按“源文件格式”分别记住上次选择的目标格式；重新修改后，新选择会成为该源格式的默认值。
• 路径记忆：记住上次保存目录，下次保存时自动从该目录开始。
• 中文/English 界面：首次启动跟随系统语言，手动选择后会记住设置。
• 批量转换：显示逐文件进度、结果和失败原因，并可单独保存或保存全部。
• 转换质量：HTML / Office 转 Markdown 保留标题、列表和代码块；CSV 支持 BOM、转义引号和字段内换行。
• PDF → Excel（智能表格提取）：支持电子文字坐标、扫描页 OCR、有框/无框表格、多表、跨页续接、合并单元格、低置信度批注与 Raw 回退。
• PDF → Word（版式还原）：内置 pdf2docx 引擎还原段落、表格、图片、字体与布局；扫描版自动 OCR 回退。Windows 10/11 版支持版式还原，Windows 7 版回退到文字提取。
• 电子书：txt/md/html → EPUB（纯本地生成）；EPUB → TXT/Markdown；MOBI → EPUB/TXT/Markdown（MOBI 解析为实验性，复杂版式可能不完整）。
• 图片合并 PDF 支持调整顺序：多张图片转 PDF 前可在队列中上移/下移，PDF 页序跟随队列顺序。
• HEIC/HEIF 图片可转换为 JPG/PNG/WebP 等（内置 ffmpeg 解码）。
• 相机 RAW 原片（CR2/CR3/NEF/ARW/DNG 等）可转换为 JPG/PNG/WebP/TIFF 等（内置 dcraw 解码，Windows 版，实验性）。
• 资源保护：单图 50MP / 16384px、图片合并 PDF 总计 100MP、批量 2GB、PDF 不限页数（1:1 转换，长文档加载较慢）、OCR 不限页数。

NCM 说明：仅保证支持 music.163.com 对应客户端下载的音乐文件。其他网站或来源虽然扩展名也可能是 .ncm，但内部格式不同，不属于本项目的兼容范围。

快速开始

1. 在 Releases 下载 v0.4.1 对应系统的安装包。
2. 安装并启动 FlyingMouse Format。
3. 拖入文件，选择目标格式并开始转换。
4. 选择保存位置；软件会记住目标格式与保存目录。

从源码运行：

源码仓库不包含体积较大的 FFmpeg、LibreOffice、Poppler 和 Tesseract 资源；普通用户请直接下载 Release 安装包。开发者从源码运行完整转换功能前，需要自行准备 bin/ 下的引擎资源。

npm install
npm run desktop

运行测试与打包：

npm test
npm run dist

Windows 版本选择

• Windows 10 / 11 x64（推荐）：下载标准资产 FlyingMouse-Format-Setup-0.4.1-x64.exe。它使用 Electron 43、Sharp 0.35 和 PDF.js 6 运行时。
• Windows 7 SP1 x64（兼容版）：下载 FlyingMouse.Format-Setup-0.4.1-win7-x64.exe。它使用同一源码和鼠鼠 UI，但在独立环境固定 Electron 22.3.27、Sharp 0.32.6 与 PDF.js 2.16.105。

Windows 7 兼容版是 Legacy 构建，不会降低标准版依赖。其 Electron 22 已停止上游安全维护，并包含无法在 Windows 7 上直接升级的已知依赖风险；PDF.js 动态代码执行已通过 isEvalSupported: false 缓解，但仍只建议离线处理可信文件。v0.4.1 通过 Windows、macOS arm64 和 macOS x64 自动化门禁以及真实 NCM/AV3A/mflac/KGG 样本回归；真实 Windows 7 SP1 x64 设备仍待验收。Windows 安装包均未签名，SmartScreen 可能提示。

macOS 版本选择

• Apple Silicon（M1 及更新）：下载 FlyingMouse.Format-Setup-0.4.1-mac-arm64.dmg。
• Intel Mac：下载 FlyingMouse.Format-Setup-0.4.1-mac-x64.dmg。

首批 macOS 包支持 macOS 11 及更新版本，未签名且未公证，可能触发 Gatekeeper。标准 NCM 可用；Audio Vivid（AV3A）NCM 依赖 Windows 专用解码器，不在 macOS 支持范围内。两个架构已在原生 GitHub runner 完成固定引擎、完整转换、包结构和 12 秒启动冒烟；真实 Mac 设备仍待验收。

完整构建只需：

npm run dist:win7

Win7 staging 使用专用 win7-package-lock.json 和 npm ci 重建；推荐使用 Node.js 22 LTS（构建脚本接受 18–22，其他主版本会在改动 staging 前拒绝）。构建脚本会绑定子进程到当前 Node、以 Unicode 安全方式复制源码、锁定 staging manifest/lockfile，并校验本地 builder 与打包资源没有越过各自允许的根目录或经过 junction/符号链接。

仅需检查 staging 时可运行 node scripts/build-win7.js --prepare-only；它不会打包。完整构建会重新准备 staging。

Highlights

• Original mouse UI with animated state changes for upload, detection, batch work, OCR, success, and errors.
• Fully local conversion with bundled FFmpeg, LibreOffice, Poppler, Tesseract, and an AVS3 decoder.
• Converts images, text, Word/WPS, Excel/WPS, PPT/WPS, PDF, audio, video, and ZIP files.
• Decrypts and converts standard NCM plus Audio Vivid (AV3A) NCM from the NetEase Cloud Music client associated with music.163.com.
• Decrypts mflac/mgg from the official QQ Music client (newer musicex variants require a QQ Music login cookie for online key exchange; when the original quality tier is unauthorized, the app automatically downloads an available tier of the same song).
• Remembers the chosen target separately for each source extension. Changing it replaces that extension's default.
• Remembers the last save directory for the next save dialog.
• Chinese and English UI. The first launch follows the system language; a manual choice is remembered.
• Batch conversion with per-file progress, results, error details, individual save, and Save All.
• Higher-quality text conversion: structural HTML/Office Markdown plus standards-compliant quoted and multiline CSV parsing.
• PDF → Excel smart table extraction for digital text and scanned pages, including multiple tables, continued pages, merged cells, confidence notes, and Raw fallback.
• PDF → Word (layout-preserving): the bundled pdf2docx engine restores paragraphs, tables, images, fonts, and layout; scanned PDFs fall back to OCR. Layout restoration is available on Windows 10/11; Windows 7 falls back to text extraction.
• E-books: txt/md/html → EPUB (generated locally); EPUB → TXT/Markdown; MOBI → EPUB/TXT/Markdown (MOBI parsing is experimental; complex layouts may be incomplete).
• Image-to-PDF ordering: when merging multiple images into a PDF, reorder items with up/down controls before converting; PDF page order follows the queue.
• HEIC/HEIF images convert to JPG/PNG/WebP and more (built-in ffmpeg decoding).
• Camera RAW files (CR2/CR3/NEF/ARW/DNG, etc.) convert to JPG/PNG/WebP/TIFF and more (built-in dcraw decoding, Windows build, experimental).
• Resource safeguards: 50 MP / 16384 px per image, 100 MP image-to-PDF decode budget, 2 GB batches, 500 PDF pages, and 100 OCR pages.

NCM scope: compatibility is guaranteed only for files downloaded by the NetEase Cloud Music client associated with music.163.com. Files from other sites may use a different internal format despite sharing the .ncm extension.

Quick start

1. Download the v0.4.1 build for your system from Releases.
2. Install and launch FlyingMouse Format.
3. Drop in files, choose a target, and convert.
4. Choose a save location. The app remembers both the target preference and save folder.

The source repository excludes the large FFmpeg, LibreOffice, Poppler, and Tesseract bundles. Regular users should install the Release build. Developers need to provide the corresponding resources under bin/ for the complete conversion feature set.

Choose a Windows build

• Windows 10 / 11 x64 (recommended): use FlyingMouse-Format-Setup-0.4.1-x64.exe with Electron 43, Sharp 0.35, and PDF.js 6.
• Windows 7 SP1 x64 (compatibility build): use FlyingMouse.Format-Setup-0.4.1-win7-x64.exe, derived from the same source and mouse UI with Electron 22.3.27, Sharp 0.32.6, and PDF.js 2.16.105 pinned in isolation.

The Windows 7 package is a Legacy build and does not downgrade the standard build. Electron 22 no longer receives upstream security maintenance, and other known legacy dependency risks cannot be upgraded without dropping Windows 7. PDF.js dynamic evaluation is disabled as a mitigation, but this build should remain offline and process trusted files only. v0.4.1 passed Windows, native macOS arm64, and native macOS x64 automation gates plus real NCM/AV3A/mflac/KGG regressions; acceptance on a physical Windows 7 SP1 x64 system is still pending. Both Windows installers are unsigned and may trigger SmartScreen.

Choose a macOS build

• Apple Silicon (M1 or newer): use FlyingMouse.Format-Setup-0.4.1-mac-arm64.dmg.
• Intel Mac: use FlyingMouse.Format-Setup-0.4.1-mac-x64.dmg.

The first macOS packages support macOS 11 or newer and are unsigned and unnotarized, so Gatekeeper may warn. Standard NCM is supported; Audio Vivid (AV3A) NCM depends on a Windows-only decoder and is unavailable on macOS. Both architectures passed pinned-engine, full-conversion, bundle, and 12-second launch gates on native GitHub runners; physical Mac acceptance remains pending.

The complete build requires only:

npm run dist:win7

The Win7 staging tree is rebuilt with its dedicated win7-package-lock.json via npm ci. Node.js 22 LTS is recommended (host majors 18–22 are accepted; other majors fail before staging changes). The script binds child processes to the active Node, copies sources safely on Unicode paths, binds the staged manifest/lockfile, and rejects local builder or packaged resources that escape their allowed roots or traverse junctions/symlinks.

Use node scripts/build-win7.js --prepare-only only to inspect staging without packaging. A complete build prepares staging again.
