Start With The Right Dimensions
Yes, you can compress images without losing visible quality. The most effective first step is matching image dimensions to their display size. A 6000x4000 pixel camera photo displayed in a 600px-wide card can be resized by 90% before compression even begins, eliminating millions of unnecessary pixels that would otherwise bloat the file.
Use Balanced Quality
For web photos, quality between 75 and 82 is often a practical range. It reduces file size heavily while keeping visual artifacts hard to notice.
Export Modern Formats
WebP and AVIF can be much smaller than JPG or PNG for web delivery. Use PNG only when you need exact lossless output.
