This article deconstructs methods, tools, and best practices to learn image resizing.

Why Resize an Image?

Reduce file size:

 Speed up website loading times.

 Optimize for printing or display on digital screens.

5 Methods of Resizing an Image:

1. Utilizing Adobe Photoshop:

1. Open the photo in Photoshop.

2. Navigate to 'Image > Image Size'.

3. Resize height/width (make sure "Constrain Proportions" is checked to keep aspect ratio).

4. Set resolution (72 DPI for web use, 300 DPI for printing).

5. Click 'OK' and save the resized image.

2. Using Free Web Tools (e.g., Canva, ResizePixel)

1. Post your picture on the website.

2. Add custom dimensions or select a preset (e.g., "Instagram Post").

3. Download the resized file.

3. Using GIMP (Free Software)

1. Open the image and navigate to "Image > Scale Image".

2. Enter new dimensions or change resolution.

3. Choose interpolation method (e.g., "Cubic" for best quality).

4. Press "Scale" and save the image.

4. Mobile Apps (e.g., Snapseed, Adobe Lightroom)

1. Upload the image into the app.

2. Resize or Crop tool is used to alter dimensions.

3. Save the edited version.

Resizing vs. Resampling: 

What's the Difference?

Resizing: Alters physical size (e.g., from 2000px to 1000px) but not pixel number.

Resampling: Changing pixel number, affecting quality. Employ "Bicubic" resampling to lose less quality.

Best Practices for Resizing Images:

1. "Maintain aspect ratio" not to distort.

2. "Save a copy" of the original file.

3. Choose the right format:

JPEG: Ideal for pictures (lossy compression).

PNG: Maintains graphic quality with transparency.

WebP: New format for reduced file size.

4. Resolution check: 72 DPI for display, 300 DPI for printing.

Common Issues & Solutions:

Pixelation: Produced by expansion beyond original resolution. Correct by resampling or using AI upscaling software.

Blurry edges: Apply sharpening filters after resizing.

Large file size: Compress images with TinyPNG after resizing.
