Quick Answers

How do I resize an image without losing quality?

Downscale to a smaller size with the aspect ratio locked — resizing downward keeps sharpness because pixels are averaged, not invented. Avoid enlarging beyond 120% of the original.

What size should a website image be?

Content images are typically 1200px wide, hero banners 1920px wide, and thumbnails 300–600px. Keep files under 200 KB where possible.

Can I resize an image to exact pixel dimensions?

Yes — enter the exact width and height. Lock the aspect ratio to avoid distortion, or unlock it to stretch to a precise size.
