Frequently Asked Questions (FAQ)

Q: What quality percentage should I use?

A: We recommend 75-80% quality, which yields massive file size savings with zero noticeable pixel degradation.

Q: Does it support bulk image compression?

A: Yes, you can upload multiple images at once, apply a uniform compression level, and download them in a batch.

Q: Will compressing change my PNG to JPG?

A: No, PNGs remain PNGs (preserving transparency) unless you explicitly choose to convert them to JPEG.

Q: Is there a file size limit?

A: Because processing runs client-side in browser RAM, files up to 100MB are supported smoothly.
