Frequently Asked Questions
Will resizing reduce image quality?
Resizing down (making smaller) preserves quality well. Enlarging (making bigger) may reduce sharpness. Our algorithm minimizes quality loss.
What's the recommended size for web images?
For web: 1920px max width for retina displays, 1200-1600px for most content images. Balance quality and file size.
Should I maintain aspect ratio?
Yes, in most cases! Maintaining aspect ratio prevents distortion. Only disable if you need exact dimensions and accept stretching.
