💡 Pro Tips for Better Image Resizing

  • Always lock aspect ratio - prevents stretched or squished images
  • Don't enlarge beyond 200% - upscaling too much causes blur
  • Use WebP for web images - smaller file size, same quality
  • Resize before uploading - platforms compress images, start with correct size
  • Keep important content centered - preview before finalizing
⚠️ Common Mistake:

Enlarging a small image beyond 200% will result in pixelation. For best results, start with the largest available image.
