Where Does Chromium Store Profiles?
Chromium keeps profiles in ~/.config/chromium on Linux, ~/Library/Application Support/Chromium on Mac, and LocalAppData on Windows.
Last updated
Chromium stores profiles per OS in the standard browser spot. History, cookies, extensions, and logins all sit inside the profile folder. The executable stays clean.
Packaging moves the folder on Linux. Native, Snap, and Flatpak each nest it differently. The chrome://version page names the live path, which beats every guide including this one when they conflict.
Where Chromium stores this, by platform
%LOCALAPPDATA%\Chromium\User Data
Default profile plus Local State and caches. Close Chromium before copying. Packaging variants move it, verify first.
~/Library/Application Support/Chromium
Same profile layout as other platforms. Often confused with Chrome paths, note the Chromium name.
~/.config/chromium
Native path. Snap and Flatpak nest it under their own roots. chrome://version shows the live one.
Frequently asked questions
How do I move a Chromium profile to a new machine?
Copy the User Data folder with Chromium closed on both ends. Same major versions transfer cleanly. Sign-in and extensions travel inside the profile.
Which profile folder is mine?
Open chrome://version and read Profile Path. That line settles every dispute about Snap, Flatpak, or distro packaging moving the folder.
Why do Linux guides disagree on the path?
Distros sandbox differently. Native uses ~/.config/chromium, Snap uses ~/snap/chromium, Flatpak uses ~/.var/app/org.chromium.Chromium. Check chrome://version first.
