Compresto is a native macOS app that batch compresses videos, images, PDFs and GIFs. It was formerly called CompressX, and many of the user comments on its site still use that name. The developer says it can make files up to 90% smaller without visible quality loss, and that everything runs offline on the user's Mac.
The app is built only for macOS. It supports both Intel and Apple Silicon Macs and requires macOS 13 or later. The site cites more than 11,024 users, and the copyright notice names Dinh Quang Hieu. The latest release mentioned is version 1.31, which added EPUB compression and translations.
Users add files by dragging them into the app, or by dropping them onto a floating Drop Zone that works without opening the main window. Whole folders can be added too, and Compresto queues the files and processes them in parallel while showing progress. The developer says hundreds of files can be handled at once.
Compression happens locally. According to the FAQ, the app uses VideoToolbox and Apple Silicon hardware encoders, so nothing is uploaded. Users pick a quality preset: the Highest and High settings typically produce changes that are imperceptible to the eye, while lower presets give smaller files at a visible cost. Typical reductions run from 50% to 90%, depending on the source format, codec and preset.
Compresto covers four media types in one app. It compresses MP4 and MOV video, JPEG, PNG, WebP, HEIC and TIFF images, GIFs and standard PDFs. The site shows example results such as a 4K clip dropping from 32.1 MB to 13.3 MB and a PDF falling from 1.3 MB to 281 KB, though results will vary by file.
Several features support repeatable workflows. Folder monitoring compresses new files automatically when they land in a watched folder. A video-to-GIF converter turns clips into lightweight GIFs, and a Raycast integration lets users start compression from the keyboard. One reviewer on the site also mentions added support for transparent video.
