With the rise of high-resolution cameras and smartphones, the demand for storage capacity has increased significantly. One of the most common storage capacities found in modern devices is 128GB. But the question remains: how many 4K photos can 128GB hold? In this article, we’ll dive deep into the world of storage capacity, file sizes, and compression to provide a comprehensive answer to this question.
Understanding File Sizes and Compression
Before we attempt to answer the question, it’s essential to understand the factors that affect the file size of 4K photos. There are two primary factors: resolution and compression.
Resolution: The Higher, the Bigger
4K resolution, also known as Ultra High Definition (UHD), has a resolution of 3840 x 2160 pixels. This is four times the resolution of Full HD (1080p) and nine times the resolution of HD (720p). As you can imagine, the higher resolution results in larger file sizes.
A typical 4K photo taken with a modern smartphone can range from 5-15 MB in size. However, this can vary greatly depending on the camera’s sensor, lens, and software optimization. For example, a 4K photo taken with a high-end DSLR camera can range from 20-50 MB or more.
Compression: The Savior of Storage
Compression algorithms play a crucial role in reducing file sizes while maintaining acceptable image quality. Most cameras and smartphones use compression algorithms like JPEG (Joint Photographic Experts Group) or HEIC (High Efficiency Image Format) to reduce the file size of 4K photos.
JPEG compression is a lossy compression algorithm, which means it discards some data to reduce the file size. This results in a smaller file size but may affect the image quality. HEIC compression, on the other hand, is a more efficient algorithm that offers better compression rates without sacrificing image quality.
Calculating the Storage Capacity
Now that we understand the factors affecting file sizes, let’s calculate how many 4K photos 128GB can hold.
Assuming an average file size of 10 MB per 4K photo, we can calculate the storage capacity as follows:
128 GB (storage capacity) x 1024 MB/GB = 131,072 MB
Divide the total storage capacity (131,072 MB) by the average file size (10 MB):
131,072 MB รท 10 MB/photo = 13,107 photos
Therefore, 128GB can hold approximately 13,107 4K photos, assuming an average file size of 10 MB per photo. However, this calculation is oversimplified and doesn’t take into account other factors that affect storage capacity.
Variables Affecting Storage Capacity
Several variables can affect the actual storage capacity of 128GB:
- Camera settings: Camera settings like burst mode, HDR, and RAW image capture can increase file sizes, reducing the overall storage capacity.
- Compression algorithms: Different compression algorithms, like JPEG or HEIC, can result in varying file sizes.
- Image quality: Higher image quality settings can lead to larger file sizes.
- Other files and data: 128GB of storage capacity is not exclusively reserved for 4K photos. Other files, like videos, apps, and operating system data, also occupy space on the device.
Real-World Scenarios
To provide a more realistic estimate, let’s consider a few real-world scenarios:
Smartphone Scenario
A modern smartphone like the Samsung Galaxy S21 Ultra or Apple iPhone 13 Pro has a 128GB storage capacity. Assuming an average file size of 10 MB per 4K photo, these devices can hold around 13,107 photos. However, considering the camera settings, compression algorithms, and other files, the actual storage capacity might be closer to 8,000-10,000 4K photos.
DSLR Camera Scenario
A high-end DSLR camera like the Nikon D850 or Canon EOS 5D Mark IV can produce larger file sizes due to its high-resolution sensor and advanced image processing. Assuming an average file size of 25 MB per 4K photo, a 128GB memory card can hold around 5,000-6,000 photos.
Action Camera Scenario
Action cameras like the GoPro Hero9 Black or DJI Osmo Action 2 are designed for capturing high-resolution video and photos in extreme conditions. Assuming an average file size of 15 MB per 4K photo, a 128GB memory card can hold around 8,000-10,000 photos.
| Device/Camera | Average File Size (MB) | Estimated Storage Capacity (photos) |
|---|---|---|
| Smartphone (e.g., Samsung Galaxy S21 Ultra) | 10 | 8,000-10,000 |
| DSLR Camera (e.g., Nikon D850) | 25 | 5,000-6,000 |
| Action Camera (e.g., GoPro Hero9 Black) | 15 | 8,000-10,000 |
Conclusion
In conclusion, the number of 4K photos that 128GB can hold varies greatly depending on the device, camera settings, compression algorithms, and image quality. While the theoretical calculation suggests 13,107 photos, real-world scenarios reveal a more realistic estimate of 5,000-10,000 photos.
When choosing a storage capacity for your device, consider the type of camera, camera settings, and intended use. If you’re a casual photographer, 128GB might be sufficient. However, if you’re a professional photographer or videographer, you may require larger storage capacities to accommodate your high-resolution files.
Remember, storage capacity is not the only factor to consider when choosing a device or camera. Other important considerations include camera resolution, sensor size, lens quality, and software optimization.
How many 4K photos can 128GB hold?
The exact number of 4K photos that 128GB can hold depends on several factors, including the camera model, image quality, and file format. However, assuming an average file size of around 10-15MB per photo, you can estimate that 128GB can hold around 8,500 to 12,800 photos.
To give you a better idea, a 4K photo taken with a high-end smartphone like the Samsung Galaxy S22 Ultra typically has a file size of around 12-15MB. On the other hand, a 4K photo taken with a mid-range smartphone like the Google Pixel 4a may have a file size of around 8-10MB.
Why do 4K photos take up so much storage space?
4K photos take up more storage space than lower-resolution photos because they contain much more data. A 4K photo has a resolution of 3840 x 2160 pixels, which is four times the resolution of a 1080p photo. This means that a 4K photo has a much larger file size than a 1080p photo, even if the image quality is the same.
In addition, 4K photos often use advanced compression algorithms and file formats like HEIC (High Efficiency Image Format) that help reduce the file size while maintaining image quality. However, even with advanced compression, 4K photos still take up a significant amount of storage space.
How can I free up storage space on my device?
There are several ways to free up storage space on your device. One of the simplest ways is to delete unused apps, photos, and videos.

Additionally, consider using a file manager app to identify and delete large files and duplicate files.
Another way to free up storage space is to optimize your camera settings to reduce the file size of your photos. For example, you can reduce the image quality or resolution, or turn off features like Location Services and HDR. You can also consider using a photo editing app to compress your photos and reduce their file size.
What is the difference between 4K and 8K photos?
4K photos have a resolution of 3840 x 2160 pixels, while 8K photos have a resolution of 7680 x 4320 pixels. This means that 8K photos have a much higher resolution and contain much more data than 4K photos. As a result, 8K photos take up even more storage space than 4K photos, typically ranging in file size from 30-50MB or more per photo.
The main advantage of 8K photos is their superior image quality, which is ideal for professional photographers and videographers. However, for most users, 4K photos are more than sufficient and take up less storage space.
Can I store 4K photos on a cloud storage service?
Yes, you can store 4K photos on a cloud storage service like Google Drive, Dropbox, or iCloud. In fact, cloud storage is a convenient and cost-effective way to store large collections of 4K photos, especially if you have limited storage space on your device. Many cloud storage services also offer automatic backup and syncing features, which ensure that your photos are safely stored and up-to-date across all your devices.
However, keep in mind that storing 4K photos on a cloud storage service may require a larger storage plan, especially if you have a large collection of photos. Additionally, uploading and downloading 4K photos can take longer due to their larger file size.
How can I compress 4K photos to reduce their file size?
There are several ways to compress 4K photos to reduce their file size. One of the simplest ways is to use a photo editing app that supports compression, such as Adobe Lightroom or Google Photos. These apps can compress your photos using advanced algorithms that reduce the file size while maintaining image quality.
Another way to compress 4K photos is to use a file compression tool, such as TinyPNG or ImageOptim. These tools can reduce the file size of your photos by up to 50% or more, depending on the level of compression you choose.
Are there any alternatives to 4K photos?
Yes, there are several alternatives to 4K photos, depending on your photography needs.
