Pimosa

About

Pimosa is a desktop toolkit for Mac and Windows with 25+ tools to compress, convert, trim, merge, and edit video, audio, image, and GIF files, plus PDF tools to merge, split, compress, and encrypt documents. It uses a simple drag-and-drop workflow and supports batch processing.

All processing happens on your device. Files never leave your computer, there are no upload limits, and the app works fully offline after installation. Video tools include a dedicated Video Cropper that crops entire clips to 9:16, 1:1, or 16:9 in one pass, along with subtitle tools that extract subtitles to SRT or ASS and add or burn in captions.

Pimosa is available for macOS (Apple Silicon) and Windows with a free three-day trial. A companion iPhone app offers essential video and image tools for compressing and editing large 4K videos and photos while keeping metadata.
