FAQ
What is the difference between compression levels?
Basic removes redundant data only, preserving full quality (~20-40% reduction). Standard applies moderate image compression (~40-60% reduction). Extreme maximizes compression (~60-80% reduction) with some quality loss.
Will compression affect content quality?
Basic mode is fully lossless. Standard and Extreme modes primarily compress embedded images; text content is unaffected.
Are my files uploaded?
No. All compression happens locally in your browser. Your files never leave your device.
