About Resize Image

Image resizing changes the pixel dimensions of your images for different use cases—whether you need smaller images for web performance, specific dimensions for social media, or larger sizes for printing. Our resizer uses high-quality resampling algorithms to maintain sharpness and detail at any size.

Choose from preset dimensions optimized for popular platforms: Instagram square (1080x1080), Facebook cover (820x312), Twitter header (1500x500), YouTube thumbnail (1280x720), and more. Custom dimensions let you enter exact pixel measurements or percentage scaling. The aspect ratio lock ensures your images don't get stretched or distorted.

E-commerce sellers resize product photos to meet marketplace dimension requirements. Web developers create multiple image sizes for responsive designs. Social media managers prepare images for different platform requirements. Photographers resize images for client deliveries at specific dimensions. Print designers prepare images at required DPI and dimensions for production.

Our resize engine offers multiple fit modes. Cover mode fills the target dimensions by cropping as needed. Contain mode fits the entire image within dimensions by adding letterboxing. Fill mode stretches to exact dimensions. Inside mode keeps the image within bounds while maintaining aspect ratio. Background color options customize letterbox fills for contained images.

Common Use Cases

  • Prepare images for social media platforms
  • Create consistent product photo dimensions
  • Resize for email newsletter requirements
  • Prepare images for web performance
  • Meet print dimension specifications

How It Works

Our image resizer uses Sharp with Lanczos3 resampling for highest quality. Fit modes include cover, contain, fill, inside, and outside. Animated GIFs are resized frame-by-frame to preserve animation.
