What is YouTube Cache?

Each app on your iPhone or Mac has a cache—a temporary collection of files stored on your device. Every time you watch a YouTube video or search for content, the app downloads data in the background to your internal storage space.

Caching helps an application seamlessly access the files it needs to run without you having to endure long load times. Therefore, caching is critical for any application to run with optimal performance.

Why is it better to clear YouTube cache?

While caching is useful, it can take up valuable storage space, which can reduce device performance.

To see how much storage space YouTube data occupies on your iPhone, go to Settings > General > iPhone Storage Space to find YouTube. Application size is the space required for an application to exist on the phone, while "Manuscript and Data" is the cached file.

What happens after deleting the YouTube cache?

After deleting the YouTube cache, the initial loading of videos and search functions may be slightly slower, as you are starting from scratch. You may also need to re-download the "downloaded" video.

At the same time, you will still retain all account data, personal settings, viewing history and related suggestions.

4. Click "Delete Application".
5. Click "Delete Application" again in the pop-up window.

While there is also an option to uninstall the application, this will not delete your "document and data" (i.e. cache).

How to clear YouTube cache on Mac

The process of clearing YouTube caches will vary depending on the browser you choose. Either way, it optimizes your browsing experience and makes the YouTube viewing experience more enjoyable. I'll cover how to clear YouTube cache in Chrome and Safari, the two most popular browsers.

How to clear YouTube cache in Chrome

In Chrome, you won't see a targeted caching method like Safari. To clear all caches:

1. Open Chrome and click the words "Chrome" in the menu bar.
2. Select "Clear browsing data...".
3. Uncheck the Browsing History and Cookies and Other Site Data check boxes while leaving the Cached Images and Files check box selected.
4. Click "Clear Data".

This process will clear all cached files for all websites you have visited.

While you have sufficient control over the data of your device, you have less control over the types of data collected by your internet browser or YouTube. Although websites are now forced to ask for consent, the data they compulsoryly collect may include various personal information you do not want them to have.

Virtual Private Networks (VPNs) help protect your personal data by hiding your IP address and encrypting your online activities. ClearVPN makes this complex process simple with an intuitive user interface that can be easily used by even the least tech-savvy. It uses industry standard encryption AES-256, which even top banks and financial institutions trust.

Once the app is opened, you can connect to the VPN with just the press of a large button and the service will choose a location for you. Whether you want to simply protect your privacy or access content from different geographic locations, ClearVPN has everything you need.

How to clear YouTube cache in Safari

The advantage of Safari is that it can locate the exact website cache you want to clear. Instead of clearing the entire cache for every website you visited, you can manage each website individually. Here is how to clear YouTube cache in Safari:

1. Open Safari browser.
2. Click the word "Safari" in the menu bar.
3. Click "Settings".
4. Search YouTube in the search bar.
5. Select youtube.com and click "Remove".
6. Click "Done".

This data contains temporary files that help speed up your experience, but over time, this data can accumulate and take up a lot of storage space. Clearing the YouTube cache can help free up storage space.

Is it OK to delete the YouTube cache?

It's totally OK to delete the YouTube cache, as this won't affect your personalized recommendations, saved videos, or viewing history. Deleting caches will only free up space on the device, delete temporary data, and give you a refreshed look.

What happens when clearing YouTube cache?

Clearing the YouTube cache deletes temporary data such as elements of the video you have watched, video thumbnails, and other information that helps the application load faster.
