Frequently Asked Questions

Does resizing reduce image quality?

Downscaling (making smaller) preserves quality well. Upscaling (making larger) can cause blurriness because the tool must interpolate new pixels. For best results, start with the highest resolution source.

What dimensions should I use for web images?

For blog posts: 1200px wide. Hero images: 1920px wide. Thumbnails: 300-400px. Social media varies by platform — use our Social Media Resizer for exact dimensions.

Best Settings

Always maintain aspect ratio to avoid distortion. For retina displays, export at 2x the display size. Resize before compressing for the smallest final file size.
