Frequently Asked Questions
How does image compression work?
Image compression reduces file size by removing unnecessary data or using more efficient encoding algorithms. Lossy compression removes some quality for smaller size, while lossless maintains quality.
Will compression reduce image quality?
Lossy compression does reduce quality slightly, but with proper settings, the difference is often unnoticeable. Lossless compression maintains perfect quality but provides smaller file size reduction.
What image formats are supported?
Common formats like JPEG, PNG, WebP, and GIF are typically supported. The tool automatically detects the format and applies appropriate compression algorithms.
How much can I compress an image?
Compression ratios vary by image type and quality settings. JPEG images can often be compressed 50-80% with minimal quality loss. PNG and lossless formats have smaller reductions.
Is image compression safe?
Yes, image compression is safe and reversible (for lossless). The original image data is not modified destructively. Always keep backups of original images if compression quality is critical.
