Photo Compression Ratio: Compress Your Images Efficiently

When it comes to image compression, it’s important to understand the concept behind compression ratio. While it may be a common term, it’s always misunderstood and taken differently into another context. For instance, users assume that they can always achieve the same quality output of a compressed image and can expect a significant loss in size when using a low compression ratio. The thing is, it depends on the compression ratio and the type of compression being utilized.

To gain a comprehensive understanding of photo compression ratios and effective compression methods, read this article and immerse yourself in what it means by photo compression ratio, as well as the methods on how to change them. Get yourself prepared and learn how to compress your images efficiently.

Part 1. What is Photo Compression Ratio

The photo compression ratio is the ratio of the number of bytes in the uncompressed photo to the number of bytes when compressed. In the simplest explanation, it refers to how much smaller a photo file becomes compared to its original size. So, when a photo has a high compression ratio, it means that the photo can be reduced to a smaller size, which can make it look blurry or pixelated. Meanwhile, when a photo has a low compression ratio, then the photo had only a small size reduction on the photo that was compressed. To better understand this, here is a comparison to what is lossy vs. lossless compression.

Lossy Compression

This is a type of image compression where a photo can significantly reduce its size and quality. It means that the photo has a high compression ratio. For example, when a photo has an original size of 10MB and was compressed to 500KB which means it achieved a 20:1 photo compression ratio.

Advantages:

• Significantly reduces file size.
• Ideal for web usage.

Disadvantages:

• Loss of image quality, especially in high compression levels.
• Not suitable for images requiring exact reproduction of original data.

Lossless Compression

Compared to lossy compression, this type of compression means there is no loss of information, and the image quality remains exactly the same as the original.

Advantages:

• No significant loss of image quality.
• Suitable for images requiring high fidelity.

Disadvantages:

• Less file size reduction.

Part 2. How to Change Compression Ratio on Photo

Adjusting the compression ratio of an image helps achieve the right balance between its quality and file size, ensuring that it looks great while taking up less space. To achieve this, you can use Photoshop. This tool allows users to perform a wide range of image editing tasks, including adjusting the photo compression ratio. With this particular feature, you can fine-tune the image quality to meet specific requirements. Here’s how you can use Photoshop to change the compression ratio of your photo:

Step 1. First, import the image file that you want to change the compression ratio by going to the File tab and clicking the Open option.

Step 2. Once you have your photo imported in Photoshop, go to the Image tab and click on the Image Size.

Step 3. Now, in the image dialogue box, set your desired resolution. After that, set your target Height and Width values. Take note that this is in Pixels. Once done, just click the OK button.

Step 4. To save your file, go to the File tab and choose Save a copy in the menu.

Step 5. After clicking the Save button, you’ll see a JPEG options box. From there, you can easily adjust the image quality of your image by sliding the bar in the Image Options section. Once done, click OK to save.

With this method, you can easily change the compression ratio of your photo. However, this can be a little complicated for some, and new users need to avail subscription to enjoy its full features.
