# Cache {#cache}

## What is caching in TYPO3? {#what-is-caching}

Caching is a process TYPO3 uses to temporarily store content and data to help
your website load faster and perform efficiently. Instead of regenerating
every page or content piece each time a visitor loads it, TYPO3 saves a
"cached" version. This way, the system can quickly serve this saved content,
reducing the load on the server and speeding up the response time for users.

## How to clear caches in TYPO3? {#how-to-clear-cache}

When you update content or make configuration changes, TYPO3 sometimes needs a
cache refresh to reflect these updates on the live site.
Here are the main ways to clear caches in TYPO3 13:

-   Clearing Cache in the backend:

    -   In the Backend, look for the Clear cache icon, which resembles a
        lightning bolt. You can find this in the [top bar](https://docs.typo3.org/permalink/t3start:top-bar@13.4).

    -   For deeper cache management, you can use the Install Tool:
        In **Admin Tools > Maintenance** you can find the option to
        clear all caches. This will refresh everything, including caches
        that aren't typically cleared through the backend top bar.
-   Clearing caches via Command Line

    For advanced users or developers, caches can also be cleared from
    the command line:

    ```bash
    ddev typo3 cache:flush
    ```

## When should you clear caches? {#when-to-clear-cache}

-   If new content, images or text doesn't show up right away.
-   When adjusting templates, extensions or system settings.
-   While working on custom code, plugins or during site updates.
