How It Works

Examples

Frequently Asked Questions

Will resizing reduce image quality?▾

Reducing dimensions (downscaling) typically maintains good quality. Increasing dimensions (upscaling) can result in pixelation. We recommend maintaining aspect ratio for the best results.

Should I lock the aspect ratio?▾

Yes, locking the aspect ratio ensures your image does not appear stretched or distorted. When you change one dimension, the other adjusts proportionally.

What size should I use for web images?▾

For web use, aim for 1200px maximum width for full-width images and 600-800px for content images. Use compression alongside resizing for optimal web performance.
