If your phone is slow, freezing, or warning you that it's low on storage space, there's a practical—and free—solution. Several apps available on the Google Play Store and App Store can help free up device memory without having to delete your photos, videos, or important files. One of these apps is available for download below:

Below, check out the five best apps to optimize your phone's space safely and efficiently.

1. CCleaner

CCleaner is one of the most popular applications for system cleaning and optimization. With an intuitive interface and detailed reports, it allows you to free up storage space by removing junk files like cache, logs, temporary files, and duplicate data, without affecting your important photos, videos, or documents.

The app also offers storage analysis features to show you exactly what's taking up space on your device. You can see which apps are consuming the most data and memory and decide if they're worth keeping. Another strong point is the system monitoring feature, which tracks CPU and RAM usage, and your phone's temperature.

Additionally, CCleaner features a one-touch optimization tool, making the cleaning process extremely simple for any user. All this without compromising performance or risking deleting essential content.

2. Files by Google

Files by Google is one of the most efficient apps for safely freeing up space on your phone. Developed by Google itself, it's reliable and easy to use. Its main function is to analyze internal storage and suggest files that can be safely removed, such as app cache, repeated WhatsApp memes, corrupted files, and other digital clutter.

One of Files' greatest strengths is its intelligence. The app recommends what to delete based on usage patterns and duplication, without ever suggesting photos, videos, or documents you've intentionally saved. This makes the cleanup process reliable and free of unpleasant surprises.

In addition to cleaning, Files offers a quick file sharing tool via Wi-Fi Direct, without the need for an internet connection, as well as a folder navigation function that makes it easy to find and organize files manually.

3. Nox Cleaner

Nox Cleaner is a powerful option for those looking for a deep and fast cleanup of their phone. It focuses on removing junk files and optimizing performance, without interfering with photos, videos, or other important user data.

With over 100 million downloads, the app features tools like a cache cleaner, a residual file remover, a RAM booster, an application manager, and even a built-in antivirus. All of this comes together in a modern, customizable interface.

One of Nox Cleaner's highlights is its intelligent analysis technology, which automatically recognizes files that can be safely deleted. This way, you keep everything that's relevant and get rid of anything that's just taking up space.

The app also offers a CPU cooling feature, ideal for those who feel their phone heats up after heavy use, and a file manager that makes it easier to view stored content.

4. SD Maid

SD Maid is an app recommended for users who want more technical and detailed control over their phone's file system. It acts as a true "digital janitor," cleaning up clutter left by uninstalled apps, organizing lost folders, and identifying duplicate files.

Unlike some more automated apps, SD Maid allows for precise scanning and shows the user what will be deleted before taking any action, ensuring greater security. It also features a database optimizer, which reorganizes installed app data to make them lighter.

Another unique feature is the task scheduler, which allows you to schedule periodic automatic cleanings. Ideal for those who want to keep their phone always in order without having to remember to do it manually.

Although the interface is a bit more technical, SD Maid is extremely lightweight and efficient, with a complete focus on the integrity of the user's personal data.

5. Avast Cleanup

Developed by the same company as the famous Avast antivirus, Avast Cleanup is a memory cleaning app that stands out for its modern look and practicality. With just a few taps, it analyzes your system and suggests actions to free up space without putting your photos or personal files at risk.

Among the features offered are a cache cleaner, media organizer (which shows duplicate or low-quality photos and videos), app manager, and the “hibernate apps” function, which reduces the resource consumption of apps running in the background.

Avast Cleanup also displays comprehensive reports on device performance, memory usage, battery life, and space usage. It also offers personalized cleaning suggestions based on your device's usage.

Another positive point is the ability to sync with an Avast account, ensuring a more integrated experience with other Avast products, such as antivirus and VPN.
