Downloading Slack takes under a minute. The most important rule is to get it from the official source — every button on this page links straight to Slack official servers, so you avoid modified or unsafe builds that circulate elsewhere.
Click the Windows download to get the SlackSetup installer, run it, and approve the Windows prompt. The 64-bit app installs with auto-update and system-tray integration, and it works the same on Windows 10 and Windows 11.
The Mac download is a universal .dmg that runs natively on both Intel and Apple Silicon. Open the .dmg and drag Slack into your Applications folder — no App Store account required, though a Mac App Store version is also available.
Slack offers official .deb and .rpm packages plus a snap. On Ubuntu or Debian, install the .deb with your package manager; on Fedora use the .rpm. The snap keeps Slack updated automatically on supported distributions.
On iPhone, iPad or Android, install Slack from the official app store. Mobile apps update automatically and sync instantly with your desktop, so your channels and messages are always current.
If you prefer working on a big screen, the Slack desktop app free download is the best way to use Slack on a PC or laptop. The download Slack for PC free option covers both Windows 10 and Windows 11, and the experience is identical on a desktop or a notebook. The Slack for Mac free download is a universal build, and the Slack for Linux download ships as official .deb, .rpm and snap packages. Because the desktop client is installed locally, it launches quickly, keeps recent content available, and adds system-tray integration and global shortcuts that the browser version does not have. Whichever platform you choose, every Slack download on this independent portal points to Slack official servers.
