Frequently Asked Questions
How much can I reduce the file size?▼
Depending on the quality setting, you can reduce file size by 50-90%. Quality 80 typically provides a great balance.
Does compression affect quality?▼
JPG and WebP use lossy compression — lower quality settings mean smaller files but may show artifacts. Quality 80-85 is usually indistinguishable from the original.
Which format compresses better?▼
WebP typically produces 25-35% smaller files than JPG at the same visual quality.
