CompressX is now Compresto
The official CompressX address now redirects to Compresto, the current name of the native macOS compression app. It batch-processes videos, images, PDFs, and GIFs locally on a Mac. The site describes reductions of up to 90 percent depending on the source, codec, and selected quality preset, while higher presets aim to keep visual changes difficult to notice.
A local workflow for large media
Compresto supports common video formats including MP4 and MOV; images such as PNG, JPEG, HEIC, WebP, TIFF, and GIF; and standard PDF files. Processing happens offline, and the official FAQ says files do not need to be uploaded. On supported Macs, the app uses Apple hardware acceleration for video work.
- Drop hundreds of files or folders into a batch with progress tracking.
- Use a floating Drop Zone without opening the main window first.
- Watch a folder and automatically compress files added to it.
- Convert a video into a lightweight GIF.
- Trigger compression from Raycast.
Less manual preparation before sharing
The app targets the recurring step between creating a file and uploading, emailing, or archiving it. Folder monitoring can make that step automatic, while drag and drop keeps one-off jobs simple. Because processing remains on the Mac, it also suits files that should not be sent to a web compression service.
