There are dozens of cache-related Chrome extensions on the Chrome Web Store. Most of them do a variation of the same thing, but the differences matter — especially around what permissions they need and whether they can target a single site.
This comparison covers the most useful ones across different use cases. We looked at permissions required, what actually gets cleared, ease of use, and whether the extension is actively maintained.
What to Look for in a Cache Cleaner Extension
Before diving into specific extensions, here's what distinguishes a good one from a bloated or risky one:
- Minimal permissions: A cache cleaner needs the
browsingDatapermission. That's it. Any extension also requesting access to all websites, your history, or tabs is taking more than it needs. - Per-site capability: Clearing all cache is nuclear. Per-site clearing is surgical. For most real-world problems, you want to fix one site without affecting everything else.
- No forced upsells: Some "free" cache cleaners nag you constantly about a paid upgrade or try to redirect you to other software.
- Still maintained: Chrome regularly updates its extension APIs. An extension last updated in 2021 may have compatibility issues.
1. Clear Cache for Specific Site
Best for Per-Site ClearingClear Cache for Specific Site
What it does: One-click cache clear for the site in the current tab. Doesn't touch any other site's cached data.
- Clears only the current site — not everything
- Minimal permissions requested
- No account, no configuration needed
- Works on any domain instantly
- Doesn't clear cookies by default (won't log you out)
- Doesn't have auto-clear on tab close
- Can't bulk-clear multiple sites at once
The Surgical Cache Fix
Clear the problem site without wiping everything. One click, and you're done.
Add Clear Cache for Specific Site2. Clear Cache (by Benjamin Bojko)
Good for: Quick All-Cache ClearClear Cache
What it does: Adds a toolbar button that clears all browser cache (and optionally other data types) in one click. Highly configurable — you choose what gets cleared and over what time period.
- Fast full-cache clear
- Configurable: choose cache-only, or include cookies/history
- Time range options (last hour, last day, all)
- Widely used and well-maintained
- Clears all sites, not just the problem one
- If misconfigured, can clear cookies and log you out
- No per-site targeting
3. Shift+Reload / Hard Reload Button
Developer UseHard Reload Button
What it does: Adds a dedicated button to the toolbar that triggers a hard reload (equivalent to Ctrl+Shift+R). Useful if you want a visible button for something you can already do with a keyboard shortcut.
- Simple and focused
- Good for users who prefer clicking to keyboard shortcuts
- Hard reload bypasses cache but doesn't delete it
- Does nothing you can't do with Ctrl+Shift+R
- Doesn't actually clear (delete) any cached files
4. Cookie AutoDelete
Privacy-FocusedCookie AutoDelete
What it does: Automatically deletes cookies from sites you've closed — but can also be configured to clear other data including cache. More focused on cookie hygiene than cache management.
- Excellent for privacy-conscious users
- Whitelist functionality (keep cookies for sites you trust)
- Automatic cleanup on tab close
- Primarily a cookie tool, not a cache tool
- Requires more configuration than cache-focused tools
- Auto-deletion can log you out of sites unexpectedly if misconfigured
- Needs 'tabs' and 'cookies' permissions (broader than a cache-only tool)
5. Web Developer (Chris Pederick)
Developer ToolkitWeb Developer
What it does: Comprehensive developer toolbar with hundreds of tools. Cache clearing is one small feature — it includes options to clear cache, cookies, and other data from a dedicated menu.
- Enormously useful for web developers overall
- Cache clearing built into a larger toolkit
- Disable cache option (keeps cache disabled while DevTools equivalent would require DevTools open)
- Very heavyweight if you only need cache clearing
- Requires broad permissions as a full developer toolkit
- Overkill for non-developers

Extensions to Avoid (and Why)
The Chrome Web Store has many cache-related extensions that aren't worth installing. Here's what to watch out for:
Extensions Requesting "Read all your data on all websites"
Some cache cleaners request <all_urls> host permissions, giving them the ability to read every page you visit. No cache cleaner needs this. This permission typically indicates adware, tracking, or other unwanted behavior packaged with the cache clearing feature.
Extensions with Upsell Walls
Several "free" cache cleaners exist solely as acquisition funnels for paid privacy or optimization software. They work, but they pester you about upgrading and may redirect your browser to promotional pages.
Outdated Extensions (Last Updated Pre-2022)
Chrome's extension APIs change over time. Extensions that haven't been updated in years may use deprecated APIs or have security vulnerabilities that haven't been patched. Check the "Last updated" date on the Chrome Web Store listing.
Do You Actually Need an Extension?
Honest answer: for clearing all cache, you probably don't. Chrome's built-in shortcut (Ctrl+Shift+Delete) opens a dialog that lets you clear cache in a few seconds. You don't need an extension for that.
Where extensions genuinely add value:
- Per-site clearing: Chrome's native per-site clearing requires navigating to
chrome://settings/content/all, searching for the domain, and clicking through several confirmations. An extension collapses this to one click. - Frequent developers and testers: If you're clearing cache for specific sites multiple times a day, the time saved by an extension is real.
- One-click toolbar access: Some people find it cognitively easier to click a dedicated button than remember a keyboard shortcut.
For casual users who rarely need to clear cache, the native Chrome tools are sufficient. For anyone who encounters cache issues regularly — developers, QA testers, power users — a well-chosen extension is a genuine time saver.
The Right Tool for the Right Job
When one site is acting up, don't nuke everything. Clear Cache for Specific Site fixes the problem without touching the rest of your browsing experience.
Install Clear Cache for Specific Site — FreeNative Chrome Cache Options (No Extension Needed)
Before installing anything, know what Chrome can do on its own:
| Task | Native Method | Speed |
|---|---|---|
| Clear all cache | Ctrl+Shift+Delete → "Cached images and files" | Fast (2-3 clicks) |
| Hard refresh (bypass cache once) | Ctrl+Shift+R | Instant |
| Clear cache for one site | chrome://settings/content/all → search domain → delete | Slow (5-6 clicks) |
| Empty cache + hard reload | F12 (DevTools open) → right-click reload → "Empty Cache and Hard Reload" | Medium |
Frequently Asked Questions
What is the best Chrome extension to clear cache?
For clearing cache for a specific site: Clear Cache for Specific Site is the best option — minimal permissions, one-click operation, doesn't affect other sites. For clearing everything quickly: the native Chrome shortcut Ctrl+Shift+Delete is hard to beat and doesn't require an extension.
Are cache cleaner Chrome extensions safe?
Reputable ones are safe. The key is checking permissions. A cache cleaner should only need the browsingData permission. Avoid extensions that request access to all websites, your history, or the ability to read page content — these are unnecessary for cache clearing.
Can a Chrome extension clear cache for one site only?
Yes. Clear Cache for Specific Site does exactly this — it clears cached data only for the site in the current tab, leaving all other sites' caches intact.
Do I need an extension to clear cache, or can Chrome do it natively?
Chrome can clear cache natively without any extension. Ctrl+Shift+Delete opens the clear browsing data dialog. For per-site clearing, go to chrome://settings/content/all. Extensions just make these tasks faster, especially per-site clearing which requires several native clicks.
What permissions should a cache cleaner extension ask for?
A minimal, safe cache cleaner needs only the browsingData permission. Be cautious of extensions also requesting tabs, history, cookies, or host permissions like "access all websites" — these are not needed for cache clearing.
Does clearing cache with an extension clear cookies too?
It depends on the extension's settings. Most cache-focused extensions clear only cached files by default and treat cookies as an optional toggle. Read the extension settings — clearing cookies will log you out of websites.
