Frequently Asked Questions
Q: Will converting PNG to JPG reduce quality? A: At quality settings of 85%+, the difference is imperceptible to the human eye. JPG uses lossy compression, but modern algorithms maintain excellent visual quality.

Q: Can I convert JPG back to PNG? A: Yes, but you won't recover the transparency or lossless quality. It's best to keep original PNG files as backups.
