Compresto
Compresto is a native macOS compression app for reducing the size of videos, images, PDFs, and GIFs locally on your Mac.
What is Compresto?
Compresto is a macOS utility for compressing videos, images, PDFs, and GIFs to smaller file sizes while keeping the workflow simple for everyday use. It is designed for people who regularly share media, upload attachments, store large files, or prepare assets for work, school, or the web. The app supports batch processing, so you can handle multiple files in one pass instead of compressing them one at a time. It also includes options aimed at practical media tasks such as shrinking videos, reducing image sizes, and working with PDF and GIF files from one desktop app. Compresto runs natively on macOS and performs compression locally on the Mac, which fits users who prefer a desktop tool rather than a browser-based service. It is published by Hieudinh and is the renamed successor to CompressX.

Safety overview
Status: Safe
Compresto is a standard desktop utility for working with your own files. Access to files you choose is normal for a compression app, and local processing can be a privacy benefit because your media does not need to be uploaded to an external service for routine use. As with any file-processing tool, review the output before replacing originals if a specific file needs exact formatting or quality.
Recommendation: Keep Compresto if you use it to reduce file sizes for uploads, email, storage, or sharing. If you no longer use it, removing the app is generally fine, but you may lose its saved settings and any convenience it provides for repeat compression tasks.
