Smartphone owners Samsung Galaxy regularly face a lack of free space. Modern flagship and mid-range cameras take pictures in high resolution, often exceeding 12 megapixels, which leads to a significant weight of each file. When the memory becomes full, the system starts to slow down and installing new applications becomes impossible. In such a situation, there is an urgent need to optimize storage.
There are several proven methods reduce the size of photoswithout resorting to deleting valuable frames. You can use the built-in capabilities of the system, third-party applications or cloud services. Each method has its own advantages and is suitable for different use cases. Understanding the principles of image compression will help you maintain a balance between the quality of images and the space occupied.
In this article we will take a detailed look at the technical aspects of working with graphics on the Android platform. We will look at standard tools Samsung Gallery, Google Photos functionality and specialized software. You will learn how to change the resolution and compression level to effectively manage the memory of your device.
Using the built-in Samsung gallery tools
The first and most accessible method is to use the standard functionality of the system. The shell One UI from Samsung implements basic editing tools that allow you to change the physical parameters of the image. To get started, you need to open the application Gallery and select the desired image. This action will launch the built-in editor.
Click on the pencil icon or button Edit at the bottom of the screen. In the menu that opens, select the resize or crop option. Crop allows you to trim off excess edges, which automatically reduces the number of pixels and, therefore, the weight of the file. However, this method changes the composition of the frame, which is not always acceptable.
Fine-tuning is available through the copy saving menu. When you try to save an edited photo, the system may prompt you to select a quality or format. Although a direct "file size" slider is rarely seen here, changing the resolution through the Resize and rotate function is an effective solution. You can choose a percentage or a specific pixel resolution.
Keep the original! Before any editing, create a copy of the file so that you always have access to the original image.
It is worth noting that the built-in editor is best suited for quickly preparing pictures for sending to instant messengers or publishing on social networks. For batch processing hundreds of photos, this method may seem time consuming. In this case, it is better to consider automated solutions.
Configuring camera settings for future shots
It is better to solve the problem of full memory preventively. Changing your camera settings will allow you to take smaller pictures initially. Open the application Camera and go to settings by clicking on the gear. Here is the key parameter Aspect ratio and Photo size.
By default, many models Samsung use the format 3:4 or 16:9 with high resolution. Switching to standard 3:4 without additional add-ons (like "Full" or "19.5:9") often produces a more natural image with less weight. It is also worth checking the enabled option HEIF (High Efficiency Image Format).
Format HEIF allows you to save images in high quality, while taking up almost half the space than traditional JPG. If saving space is your goal, make sure this feature is enabled in the Aspect Ratio settings. However, keep in mind that older devices may not support this format for viewing.
⚠️ Attention: The HEIF format may not open on some older computers or on certain social networks without first converting. Use it if you plan to store photos only on modern devices.
Another important aspect is the shooting mode. Using the mode Pro or shooting in RAW creates huge files (25-50 MB). For everyday life, the automatic mode is sufficient, which applies compression algorithms immediately at the time of shooting.
Use of third-party compressor applications
When the built-in tools are not enough, specialized applications from the store come to the rescue. Google Play. They allow you to flexibly adjust the compression level, change the resolution, and even process photos in batches. This is especially true if you need to prepare an archive for sending by email.
One of the popular solutions is the application Lit Photo or Photo & Picture Resizer. After installation, you select a folder with images and set a target size or compression percentage. The algorithms of such apps are often more effective than standard ones, as they use advanced methods encoding data.
- 📱 Lit Photo - allows you to reduce the size of several photos at once, has a clear interface and previews the result before saving.
- 🖼️ Image Size - professional a tool where you can set exact dimensions in pixels, centimeters or inches, as well as change DPI.
- 🗜️ Compress Photos & Pictures - an application with an automatic mode that automatically selects the optimal balance between quality and weight of the file.
It is important to carefully monitor the quality slider. At a value below 60-70%, compression artifacts, so-called “digital noise” or blur, may appear on the image. It is recommended to test compress one file to find the optimal balance.
☑️ Check before compression
Comparison of image compression methods
The choice of method depends on your goals: do you need maximum quality for printing or is only the readability of the image on the smartphone screen important. Different approaches give different results in terms of the final volume and visual component.
| Method | Quality | Compression level | Complexity |
|---|---|---|---|
| Built-in editor | High | Low (10-20%) | Low |
| Resolution change | Medium | Medium (40-60%) | Low |
| Third-party apps (JPG) | Customizable | High (up to 90%) | Medium |
| Conversion to WEBP | High | Very high | High |
As can be seen from the table, third-party applications give the greatest control over the result. However, for one-time operations, regular funds are quite sufficient. Converting to the WEBP or PNG-8 format (for graphics without gradients) can give a gain in space, but will reduce compatibility with some galleries.
Optimization through cloud services
A modern approach to storing photos involves the use of cloud technologies. The service Google Photos, pre-installed on most Samsung, offers the "Space Saving" function. It automatically replaces the originals on your device with optimized versions.
To activate this feature, open Google Photos settings and select the quality "Space Saver" (formerly "High Quality"). Photos will be compressed to 16 MP (for photos) and 1080p (for video). Visually, the difference on the smartphone screen is almost invisible, but the volume is reduced significantly.
After synchronization is turned on, a button Free up spacewill appear. By clicking it, you will delete from your device those copies that are already securely stored in the cloud in a compressed format. This is the safest way to free up gigabytes of memory without the risk of losing data forever.
What if you need the original version?
If you delete the original from your phone, but later need it in full resolution, you can restore it from the cloud. Simply open a photo in the Google Photos app, tap the three dots, and select "Download." The original file will be returned to the device memory.
The disadvantage of this method is the need for a stable Internet connection for the initial download and the availability of free space in the cloud account. The free limit is 15 GB, after which a subscription will be required.
Technical aspects and file formats
Understanding the differences between formats will help you make informed decisions. The main format JPG uses lossy compression. This means that some color information is discarded. When resaving JPG multiple times, the quality degrades.
The format PNG uses lossless compression, but weighs more, especially if the photo has a lot of color transitions (for example, a portrait). PNG is ideal for screenshots, drawings or images with text, where clear boundaries are important.
When reducing the size, it is important not to confuse resolution (number of pixels) and bitrate/quality (degree of color detail). Reducing the resolution (for example, from 4000x3000 to 2000x1500) physically removes pixels. Reducing the quality leaves the pixels in place, but simplifies the information in them.
Optimal strategy: Store the originals on an external hard drive or PC, and keep optimized copies on your smartphone for quick access.
⚠️ Attention: The Settings menu interface and item names may vary slightly depending on the operating system version Android and shell version One UI. If you do not find this option, use the search inside the settings menu.
Frequently asked questions (FAQ)
Will the quality of the photo deteriorate after reducing the size?
Yes, when reducing the size (especially with strong compression JPG) quality inevitably decreases. Artifacts may appear and small details may disappear. However, with moderate compression (up to 2-3 MB) on a smartphone screen, the difference is often invisible to the eye.
Is it possible to restore the quality of a reduced photo?
No, the lossy compression process is irreversible. Increasing the resolution back (upscaling) will not bring back the lost details, but will only stretch the existing ones, often making the picture look soapy. Always save the original separately.
Is it safe to use free compression applications?
Most popular applications from Google Play are safe. However, avoid apps that require strange permissions (access to contacts, calls) to work with photos. Read reviews and check access rights.
How to reduce the size of a photo to send to WhatsApp?
WhatsApp compresses photos automatically. If you want to send a file without losing quality, select it as "Document" rather than "Gallery Photo". In this case, there is no need to apply compression.
Why do photos on Samsung weigh more than on other phones?
Cameras Samsung often use complex processing algorithms (HDR, noise reduction), which save more data in the file. Additionally, settings may offer higher resolution than competitors.
