Frequently Asked Questions
Find answers to common questions about our tool and how it works.
Compression is too much when visible artifacts appear, text becomes unreadable, or important details are lost. Test with actual users when possible.
Use lossless for graphics, text, and when quality is critical. Use lossy for photographs and when file size is more important than perfect quality.
Lossless compression provides size reduction without quality loss, but ratios are typically 2:1 to 5:1 compared to 10:1+ for lossy compression.
