How to Freeze (Discard) a Tab in Chrome Manually

Chrome's Memory Saver decides on its own which idle tabs to free up and when. Most of the time that's fine — but if you want a specific tab's memory back right now, without waiting for Chrome to get around to it, there's a hidden page built for exactly that.

Open chrome://discards

Type chrome://discards into the address bar and hit Enter. It won't show up in any menu — it's an internal Chromium page, the same family as chrome://system or chrome://version — but it's a standard part of every current Chrome build, not a hidden flag or dev-only feature.

The page lists every tab currently open across all your windows, with a few columns worth knowing:

• Site — the tab's title and origin.
• State — whether the tab is Active, Backgrounded, or already Discarded.
• Actions — a column of links, including Discard, for that specific tab.

Discard a tab on demand

Find the row for the tab you want to free, and click Discard in the Actions column. Chrome unloads the tab's process right away — the memory goes back to your system immediately, no waiting for idle time or a memory-pressure trigger.

The tab doesn't disappear. It stays exactly where it was in your tab strip, favicon and title intact, just not running anymore. Click it, and Chrome reloads the page from scratch — same as opening it for the first time, which means:

• Scroll position resets to the top.
• Any text typed into a form but not submitted is gone.
• Video or audio playback position isn't preserved.

That trade-off is identical to what Memory Saver does automatically — chrome://discards just lets you trigger it yourself, on the tab you choose, the moment you choose it, instead of waiting on Chrome's own schedule.

Why use the manual page instead of just enabling Memory Saver

Memory Saver (chrome://settings/performance) is the automatic version of the same mechanism — it watches for idle tabs and discards them for you in the background. Turning it on is the right move for ongoing, hands-off memory relief. chrome://discards is for a different moment:

• You need memory back right now — Chrome is sluggish mid-task and you don't want to wait for Memory Saver's own timing.
• You know exactly which tab is safe to discard — a research tab you're not touching for the next hour, a reference page you'll come back to later — and you'd rather pick it yourself than let a heuristic guess.
• You want to check what's already discarded. The State column tells you at a glance which tabs Chrome has already frozen, without clicking through each one.

What Chrome won't auto-discard

Whether you're using Memory Saver or the manual page, some tabs are excluded from discarding by design:

• Tabs playing audio or video. Chrome won't interrupt active playback.
• Tabs mid-download. A discard would kill the download.
• Tabs with unsaved form input, like a half-written email or a long form you haven't submitted.
• Pinned tabs get a much lower discard priority, though pinning isn't an absolute guarantee the way the three cases above are.

You can still manually discard most of these from chrome://discards if you're certain — the manual Discard link overrides the usual caution, so double-check the row before clicking it.

When discarding isn't the fix you actually want

Discarding buys you memory back on a tab you're likely to revisit soon. It doesn't help with the tab you opened three weeks ago "just in case" and haven't looked at since — that tab still shows up in your tab strip, still needs scanning past, and still gets recreated in full the moment you click it.

Amazing Tabs is built for that second case — tabs you're done with for now, not tabs you're about to reload:

• Save a tab and close it for real, not discard-and-reload — the process ends completely and there's nothing left to click back into by accident.
• Press ⌘K / Ctrl+K to search what you've saved by title or content, instead of scanning chrome://discards trying to remember which row was which.
• Free for up to 100 saved links, so clearing out the tabs you're not actively using costs nothing to try.

Stop discarding tabs you're never going back to. Add Amazing Tabs to Chrome — free, no signup. Save what you're keeping, close the rest for good, and search it all back in seconds.

Quick recap

• chrome://discards is a hidden but standard Chrome page that lists every open tab and lets you manually free one's memory on demand.
• Click "Discard" in the Actions column to unload a specific tab's process immediately — no waiting for Memory Saver's own timing.
• Discarding isn't closing. The tab stays in your tab strip and reloads from scratch — losing scroll position and unsaved input — the next time you click it.
• Audio, downloads, and unsaved forms are excluded from auto-discarding, though you can still override that manually if you're sure.
• For tabs you're actually done with, saving and closing beats discarding — nothing left to accidentally reload.
