Frequently Asked Questions

What's the best format for resized images?

JPG for photographs, PNG for graphics with transparency, WebP for web use - our tool optimizes each format appropriately.

Can I resize without losing quality?

Downscaling (making smaller) maintains excellent quality. Upscaling has limits - we apply sharpening to maximize quality when enlarging.

How do I maintain aspect ratio?

Our tool automatically locks proportions by default. Simply enter width OR height, and we'll calculate the other dimension.
