5 Golden Rules for Perfect Image Compression Without Quality Loss

A comprehensive guide on balancing bitrates, handling HEIC files, and leveraging smart layout bounds to save storage.

Compression is a tradeoff between visual quality, load speed, and compatibility. The trick is to compress based on what the image contains instead of using one universal export setting.

Photos tolerate different artifacts than UI screenshots. Gradients, text, and sharp edges need cleaner encoding. Busy photography can usually be compressed more heavily without obvious damage.

Always test the image at the size users will actually see it. A file can look rough at 200% zoom and still be perfect in the final interface.
