If setting image quality below 60% creates blurry, pixelated images. Keep file resolution between 75–85% for the best result.
Using the wrong file format
PNG is best for logos, without background images and graphics. JPG is better for capturing weeding and shooting photos. WebP is google format and it is smaller than both.
Repeatedly compressed image
Again and again compressing a JPG file makes it look bad each time. Always start from the original file.
Ignore the preview
Always check the output result of the image before downloading. If image quality is good then you can download or try setting between 75-85% for the best result.
Resizing large images first
If your image is 4000px large but your website only shows it at 800px, resize it first. Use the TrimIMG Image Resizer and then compress for maximum savings.
