Frequently Asked Questions

Q: Why does it export as JPEG?

The JPEG format supports a numeric compression quality index between 0.1 and 1.0, making it the ideal standard format for reducing image file sizes.

Q: What is a good quality percentage?

A quality rating of 0.75 to 0.85 (75% to 85%) offers massive file size reductions (up to 80% smaller) with virtually zero visible difference in clarity.
