Understanding Lossless vs Lossy Compression: What's the Difference?

Image compression is the process of reducing file size. There are two main types: lossless and lossy. Each has its own strengths and use cases.

Lossy Compression

Lossy compression removes some data from the image to achieve a smaller file size. This is commonly used in JPG and WebP formats. It's best for photographs where small quality drops aren't noticeable.

Lossless Compression

Lossless compression reduces file size without losing any original data. This is used in PNG and WebP lossless formats. It's ideal for logos, icons, and graphics where clarity is essential.

Conclusion

If you need maximum quality, go lossless. If you need maximum performance, go lossy.
