Question

takeaway: you get a perfect, high-quality image with no data loss, but the typically larger than those achieved with lossy compression.

can cause pixelation

lossy compression
lossless compression

Explanation:

🆕 New Concept Discovered: Lossy vs. Lossless Compression
Understanding how data is reduced in size.

Step 1: Define the two compression types

• Lossy compression permanently discards some data to significantly reduce file size. When compressed too much, the loss of detail becomes visible, often resulting in blocky artifacts or "pixelation."
• Lossless compression reduces file size without losing any original data. The decompressed file is an exact pixel-for-pixel match of the original, meaning it cannot cause pixelation or quality loss.

Step 2: Match the characteristic

The card asks which type of compression "Can cause pixelation".

Because pixelation is a result of losing image detail and data during the compression process, it is a characteristic of Lossy Compression.

Answer:

Lossy Compression
