免费开源的 Windows/macOS 截图工具，集成标注、长截图、OCR 与录屏

提供 Snow Shot 截图工具和 Snow Image Viewer 看图软件的源码，集截图、录屏、OCR 和图片浏览于一体，适合需要本地桌面图像处理工具的用户。

核心能力

  • 支持截图、标注、长截图、贴图、文字识别与录屏
  • 内置默认 OCR 资源，基于 simd-paddle-ocr-rs 子模块
  • 附带 Snow Image Viewer 图片查看器
  • 提供 WinGet、Scoop、Homebrew 多种安装方式
  • Windows 支持 ARM64 原生构建与交叉编译

容易踩的坑

源码构建需先执行 git submodule update --init --recursive 初始化 OCR 子模块；Scoop 升级前须先退出 Snow Shot 并使用 Scoop 而非应用内置更新器；OCR 子模块使用独立 nightly 工具链，Cargo 命令需在其目录内运行。

内容由模型根据 README 生成，可能不完整或不准确，以官方文档为准。看原文 README

    在 GitHub 打开

    Snow Apps

    Snow Apps repository, providing source code for Snow Shot and Snow Image Viewer.

    For native Windows ARM64 builds and packages, see Windows ARM64 build support, including cross compilation, OCR preparation, and release validation prerequisites.

    Install Snow Shot on Windows

    Download the installer from Snow Shot releases. Install the offline Windows x64 package from the WinGet community repository with:

    winget install --exact --id mg-chao.snow-shot --source winget

    This package includes published beta versions and the default OCR resources. See WinGet release support for upgrades, removal, and maintainer setup.

    Once Snow Shot's submission is accepted into Scoop's official Extras bucket, install the portable Windows x64 package with Scoop:

    scoop bucket add extras
scoop install extras/snowshot

    The Scoop package follows stable releases and includes the default OCR resources. Quit Snow Shot before running scoop update snowshot; use Scoop rather than the app's built-in updater. Settings and history persist across upgrades and ordinary uninstall. See Scoop release support for removal, data locations, and maintainer setup.

    Install Snow Shot on macOS

    Apple Silicon Macs running macOS 15 or later can install the stable release with:

    brew update
brew install --cask mg-chao/tap/snow-shot
brew upgrade --cask snow-shot
brew uninstall --cask snow-shot

    Installation reuses Snow Shot's local signing identity and may request Keychain access and macOS privacy permissions. See Homebrew installation and migration for existing installations, custom app directories, and recovery.

    Maintain the OCR submodule

    snow-crates/crates/simd-paddle-ocr-rs/ is a Git submodule with its own repository, history, branches, and releases. Snow Apps records the exact OCR commit to check out. The submodule is excluded from the Snow Crates Cargo workspace so it retains its own pinned nightly toolchain and lockfile. Run its Cargo commands from the submodule directory.

    After cloning Snow Apps, initialize the submodule from the repository root:

    git submodule update --init --recursive

    For a new clone, git clone --recurse-submodules initializes it automatically. Submodule updates normally check out a detached HEAD. Before editing OCR code, switch to main or a feature branch inside the submodule:

    git -C snow-crates/crates/simd-paddle-ocr-rs switch main

    Follow the submodule's README and AGENTS.md for its build and validation commands. Commit and push OCR changes to its own repository first, then record the new revision in Snow Apps:

    git add snow-crates/crates/simd-paddle-ocr-rs
git commit -m "build(ocr): update simd paddle ocr submodule"
