How to uninstall Gifski on Mac
Save any conversion in progress before removing Gifski. The app’s official guide documents Command + S to save the resulting GIF; keep the original videos and saved GIFs in their own folders, and open any backup copy before uninstalling.
Quit and remove Gifski
Finish or cancel the conversion, quit Gifski with Command + Q, then move Gifski.app from Applications to Trash. This procedure covers the Mac desktop app, including the App Store edition tested here. A separately installed command-line encoder is a different installation.
Review its share-extension data
The October 4 test found these two Gifski share-extension locations. After quitting the app, use Shift + Command + G in Finder to inspect each exact path. Copy any contents you want to retain before moving the named item to Trash, and leave other apps’ containers alone.
~/Library/Application Scripts/com.sindresorhus.Gifski.ShareExtension: the share extension’s script directory, empty in the recorded test.~/Library/Containers/com.sindresorhus.Gifski.ShareExtension: the share extension’s local container, 4 KB in that test. Its small test size does not establish what another installation contains.
Saved GIFs and source videos outside those directories are not targets of this procedure.
A separately installed Homebrew encoder
Homebrew’s gifski formula installs the command-line encoder, not this Mac app. Removing Gifski.app does not uninstall that formula. Keep it if your scripts still use it; if you also intend to remove that independently installed encoder, use its package manager:
brew uninstall gifski
This is a formula command, not a cask uninstall or a zap operation.
Check the result
These checks only read process names and the two recorded locations:
pgrep -il 'Gifski'
ls -ld "$HOME/Library/Application Scripts/com.sindresorhus.Gifski.ShareExtension" "$HOME/Library/Containers/com.sindresorhus.Gifski.ShareExtension"
command -v gifski
No process match means no matching process name is running; identify any match before quitting it. An ls result means that path remains, “No such file or directory” means only that exact path is absent, and a permission error leaves it unverified. A path from command -v identifies a surviving CLI to inspect separately; no result does not prove the desktop app was removed.
What Mole lists
Mole lists the matching share-extension script directory and container when they exist. Direct bundle-ID suffix matches are selected by default; a separately identified embedded helper is listed for individual review. Inspect the actual checkbox and preserve any needed contents before confirming removal. GIFs and original videos in your document folders are outside these extension rows.
These defaults assume “Remove data and settings with apps” is off. Opting in also selects eligible reviewed app data; shared stores and protected data retain individual review or stay locked.
What this test covered
The October 4, 2026 record covers Gifski 3.0.6 from the Mac App Store. The app and the two explicitly selected share-extension rows were moved to Trash, and their original paths were absent afterward. This record did not capture an installation-to-first-launch window or validate conversion, saved-media recovery, updates, or a separately installed CLI.
