FAQs:

Q1: What is lossy compression?

A: Lossy compression reduces file size by removing some data, often imperceptible, but it can affect quality.

Q2: What’s the difference between lossy and lossless compression?

A: Lossless retains all data and quality, while lossy reduces data and file size, sometimes affecting quality.

Q3: How do I maintain quality during compression?

A: Use lossless compression tools like TinyPNG or adjust settings on lossy compressors for minimal quality loss.

Q4: Are there free tools for quality compression?

A: Yes, TinyPNG and ImageOptim are popular free tools for preserving quality during compression.

Q5: Does file format affect compression quality?

A: Yes, JPEG is lossy and may lose quality, while PNG offers lossless compression, retaining more detail.
