macOS 剪贴板优化器，复制即压缩图片视频 PDF，粘贴更小发送更快

macOS 剪贴板优化工具，自动压缩复制进来的图片和视频，用 pngquant、jpegoptim、gifsicle 等工具减小体积，省磁盘和带宽。

核心能力

  • 复制图片到剪贴板时自动压缩到最小体积
  • 停止录屏后自动优化视频并生成浮动缩略图
  • 用 Apple Silicon 媒体引擎编码视频以省电
  • 支持快捷键按比例或指定尺寸缩小图片视频
  • 通过 macOS 快捷指令把优化接入自动化流程

容易踩的坑

仓库提交已暂停，后续开发转为私下进行；免费版对录屏、截图、按需优化和快捷指令每会话限 5 次；依赖 pngquant、jpegoptim、gifsicle、ffmpeg、libvips、gifski、ghostscript 等开源工具做优化

    Optimise images as soon as you copy them

    As long as the Clop app is running, every time you copy an image to your clipboard, Clop will optimise it to the smallest possible size.

    The optimised image will have minimal to zero loss in quality, and will be ready to paste in any app.

    Screen recordings as small as screenshots

    Sending screen recordings becomes 10x faster with Clop. The app will optimise the video as soon as you stop recording.

    The video will be available as a floating thumbnail, ready for you to drag and drop in any app.

    Clop can use Apple Silicon's dedicated Media Engine chip for battery-efficient video encoding without using the CPU.

    Downscale in a pinch

    Get images and videos ready for sharing by scaling them down to any resolution.

    Use handy hotkeys or the floating buttons to downscale the image or video and get an even smaller file size.

    • - downscales incrementally from 90% until 10% of the original resolution
    • 1..9 are for downscaling to specific sizes

    Power user features

    1. On-demand optimisation

    Press Ctrl-Shift-C to manually optimise the current clipboard.

    The action works on images, video files, paths, URLs, even base64 encoded images.

    For more aggressive optimisation, Ctrl-Shift-A is also available.

    2. Compatible formats

    Clop automatically converts less compatible formats like HEIC, tiff, mov to formats understood by most devices.

    The conversion is fully configurable from the app settings.

    Original files are kept in a backup folder which can be accessed from the app menu.

    3. macOS Shortcuts

    Integrate Clop optimisation in your workflows through native macOS Shortcuts.

    • Downscale and optimise images that you email weekly
    • Download optimised images directly into your slideshow
    • ..and so on

    Free vs Pro

    Free version features are free forever.

    After the 14-day trial, the app will continue to work with the free features.

    Technical details

    Clop uses the following open source tools for optimising files, images and videos:

    • pngquant for PNG
    • jpegoptim for JPEG
    • gifsicle for GIF
    • ffmpeg for videos
    • libvips for resizing images
    • gifski for converting videos to GIFs
    • ghostscript for optimising PDFs

    It may also use libvips for resizing images if it is installed on your system.

    The app is licensed under GPLv3.

    What's up with the hat?

    Clop is the Romanian word for a traditional straw hat with a high crown and raised conical brim, worn more as an adorment in days of celebration.

    We thought "Clipboard Optimizer" sounds a bit too technical and doesn't roll off the tongue as easily. We're Romanian ourselves and we thought it might be a good idea to keep the memory of our traditions from dying completely, with whatever little we can do.
