FREQUENTLY ASKED QUESTIONS
Q: What quality percentage should I use?
We recommend 75-80% quality, which yields massive file size savings with zero noticeable pixel degradation.
Q: Does it support bulk image compression?

Q: Will compressing change my PNG to JPG?
No, PNGs remain PNGs (preserving transparency) unless you explicitly choose to convert them to JPEG.
Q: Is there a file size limit?
Because processing runs client-side in browser RAM, files up to 100MB are supported smoothly.
