Tips for Getting the Best Results

Always start with the highest quality original image you have
For web use, aim for WebP format with 75–80% quality
Resize before compressing — smaller dimensions mean smaller files regardless of compression
Keep original files for archiving; use compressed/converted versions for delivery
