What is compression artefact?

This noticeable reduction in quality or distortion of the image is called compression artefact. JPEG is a lossy compression specification that takes advantage of human perception.

Why is text compressed?

Almost all forms of data that we see on the internet — text, image, video etc. — are compressed to reduce the size of data and ensure faster transmission. Choosing the correct format and compression is a major factor that determines image size. Compression can be of two types — lossless and lossy.

What are the two types of compression?

Compression can be of two types — lossless and lossy. In lossless compression, it is possible to reconstruct the original image from the compressed image because there is no information loss during compression. This is not the case in lossy compression i.e. data loss in lossy compression is irreversible.

Is PNG better than GIF?

Given that PNG is now supported across all major devices and that PNG compression is about 5–25% better than GIF compression, GIF images are now mainly used only if the image contains animations. In this case the GIF image is as sharp as the PNG image on the edges.

Why are images compressed?

Almost all forms of data that we see on the internet — text, image, video, etc. — are compressed to reduce the size of data and ensure faster transmission. Choosing the correct image format and compression is a major factor that determines image size.

Is lossless compression lossy or lossy?

In lossless compression, it is possible to reconstruct the original image from the compressed image because there is no information loss during compression. This is not the case in lossy compression. Data loss in lossy compression is irreversible. Lossy compression algorithms always have a superior compression ratio (the ratio of size of compressed image to original image) as compared to lossless compression. However, this compression ratio comes at a cost of reduced quality that becomes increasingly evident as we zoom in on the image. This noticeable reduction in quality or distortion of the image is called compression artefact.

Which is better, JPG or GIF?
