How to Compress Images Without Making Them Look Blurry
Good compression is not about forcing every image to the smallest possible file. The goal is to remove unnecessary weight while keeping enough quality for the actual use case.
Keep an original copy, define the rule before processing, and verify the result after processing.
Resize before lowering quality
If a website only displays an image at 1200 pixels wide, uploading a 5000-pixel source is usually unnecessary.
Reducing dimensions can save more space than aggressive quality reduction.
You rarely need maximum quality
JPEG and WebP often retain good visual quality at high-but-not-maximum settings.
Start with a moderate-high quality setting and lower it gradually until artifacts become visible.
Screenshots and photos behave differently
Photographs tolerate compression better than screenshots containing small text, UI elements, and tables.
Use different settings for different image types.
Check on the real device
An image that looks fine on a desktop may behave differently on a phone.
For web publishing, verify both visual quality and loading performance in the actual page.
