DownloadHelper CoApp
DownloadHelper CoApp is the companion desktop app used by Video DownloadHelper to enable browser tasks such as media conversion and advanced downloads.
What is DownloadHelper CoApp?
DownloadHelper CoApp is a native macOS helper app for the Video DownloadHelper browser extension. It handles operations that a browser extension cannot complete on its own, including certain media processing and conversion tasks needed during video downloads. People typically install it when Video DownloadHelper asks for a companion application to unlock advanced downloading workflows. On Mac, it works alongside a supported browser rather than serving as a standalone video downloader interface. Users are most likely to encounter it while saving streaming media, converting downloaded files, or troubleshooting extension features that depend on desktop integration. ACLAP publishes the companion app as part of the broader Video DownloadHelper toolset.
Key features
- Enable advanced download tasks that require a native desktop companion
- Process and convert media files for supported download workflows

Safety overview
Status: Mostly safe
This is a legitimate companion app tied to the Video DownloadHelper browser extension. Its desktop integration and media-processing role are normal for its purpose, but users should expect it to interact with downloaded media files and with the browser extension that invokes it. Keep it only if you use Video DownloadHelper features that need the companion app, and download updates from the publisher’s site rather than third-party download pages.
Recommendation: Keep DownloadHelper CoApp if you use Video DownloadHelper for downloads or media conversion that require the companion app. If you no longer use that extension or do not need its advanced features, you can remove this app without affecting macOS itself, though related extension features may stop working.
