Sometimes, we may need to convert images from KB to MB. For instance, upload to websites, print high-quality photos, make ID photos, etc. So, how do you complete this task? This guide introduces the tools to convert KB to MB size easily. Let’s check.
KB & MB in Picture Size: Definition & Difference
KB (Kilobyte) and MB (Megabyte) are units of the computer field to measure file size and transmission size. 1 MB equals 1024 KB. The number is bigger, and the file size is bigger. Besides using KB and MB to indicate an image size, it is also used for other files like documents, audio, and video.
In terms of image processing, in the same format, the bigger file size (e.g., in MB) often shows more details, like higher resolution, more delicate color, etc. In smaller file sizes (e.g., in KB), the image is often compressed and lacks details for better transmission.
Look at the image in these two sizes below:
From the two images, these differences show how MB gives more visual power—better color, higher resolution, and clearer quality. And let’s see the general comparison of KB vs MB Images below.
| Feature | 100 KB Image (Typical) | 1 MB Image (Typical) |
| File Size | Around 100 KB | Around 1 MB |
| Dimensions | 600 × 800 to 900 × 1200 pixels | 2000 × 3000 pixels or more |
| DPI (Resolution) | 72–96 dpi | 96–300 dpi |
| Bit Depth | 24 | 24 |
| Image Quality | Low: blurry, less detail | High: clear, sharp, detailed |
| Best Use | Web pages, email, previews | Printing, ID photos, editing |
From the table, we can see the MB is better than the KB in terms of quality. Here’s what usually changes when image size increases when KB is converted to MB:
- Image size (width × height) is larger.
- More pixels allow for more detail.
- The colors are clearer and crisper.
- The file is better for printing for a higher resolution,like posters, etc.
How to Increase Image Size From KB to MB
So, if you want to convert KB to MB with better quality, size, and more vibrant presentation, there are many ways to do that. Here are some methods using different tools.
Method 1: Increase Image Dimensions (Resolution)

Method 2: Save in a Less Compressed Format
Sometimes, the image is small through heavy compression. One method of rectifying this is to save the image in a format that is capable of holding more data. This method assists in file size increase and keeping higher-quality images. But it is best when the image already has enough pixels or detail. On very small images, the size increase will be negligible in this case.
Photoshop
Photoshop also enables you to save images in different formats at different compression levels. Saving in a format with less compression will enable you to increase the file size and maintain more details. It’s an easy way to convert KB to MB without making drastic changes to the image.
Step 1: Open your image in Photoshop.
Step 2: Navigate to File > Save As.
Step 3: Choose PNG or TIFF from the format list.
- For TIFF: In the pop-up, select None or LZW from Compression to reduce loss.
- For PNG: PNG saves images at full quality by default. It may slightly increase the file size, but it will not make blurry or low-detail pictures look sharper.
Step 5: Click Save to finish.

Method 3: Reduce Compression Quality
Method 2 is directed at saving the image in less compressed file formats such as PNG to reduce the compression. Method 3 keeps the same principle but implements it in another way. Instead of modifying the format, you change the compression level when saving the image. By choosing to reduce the compression, you can actually make the file larger and keep the high quality.
Photoshop has a Save for Web (legacy ) tool. It gives you more control over file size and compression of images. This is unlike normal saving, as you can set the JPEG quality better. You have a slider to move from 0 to 100 and see its real-time effect on the file. Here are the steps.
Step 1: Open your photograph in Photoshop.
Step 2: Go to File > Export > Save for Web (Legacy).
