Image Compressor FAQ
How do I compress an image without losing quality?
Upload the image and lower the quality slider gradually while watching the preview. Settings around 70–80% usually cut file size dramatically with no visible difference.
How do I get an image under 100 KB?
Lower the quality until the estimated size is under 100 KB. If it’s still too large, resize the image to smaller dimensions first with the Image Resizer.
