Tips for Effective Image Resizing
- Understand Aspect Ratio: The aspect ratio is the proportional relationship between an image’s width and height. Maintaining the aspect ratio prevents distortion.
- Pixel Dimensions vs. File Size: Pixel dimensions determine the image’s size in pixels, while file size (in kilobytes or megabytes) indicates the amount of storage space it occupies.
- Choose the Right File Format:
- JPG: Suitable for photographs and images with complex colors.
- PNG: Ideal for images with transparent backgrounds and sharp lines.
- GIF: Best for animated images and simple graphics.
- Optimize for Web: Use web image size optimiser tools and techniques to reduce file sizes without sacrificing quality.

Advanced Resizing Techniques
- Resampling: This process involves changing the number of pixels in an image. Resampling can affect image quality, so it’s essential to use it judiciously.

- Compression: Compression reduces the file size by removing redundant data. Lossy compression (e.g., JPG) can reduce file size significantly but may also reduce image quality. Lossless compression (e.g., PNG) preserves image quality but results in larger files.
