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.
