Tips for Successful Image Resizing

Resizing images is more than just changing dimensions. Here are some tips to help you get the best results with the image resizer:

  1. Maintain Aspect Ratio: When you resize an image, it’s essential to preserve its original aspect ratio. This means that if you change the width, the height should automatically adjust proportionally, preventing distortion and awkward stretching of the image.
  2. Don’t Increase Image Size: As a general rule, an image resizer works best for making your image smaller rather than larger. In the same way that changing aspect ratio can cause distortion, making an image larger can reduce image quality and make the final image look blurry or pixelated. If you need to enlarge an image, try using specialist upscaling software such as inPixio’s Photo Maximizer.
  3. Balance Image Quality and File Size: The image format you choose can affect both image quality and file size. For web use, JPEG is often the best choice, offering a good balance between quality and file size. However, for printing or situations where quality is paramount, consider lossless formats like PNG or TIFF.
  4. Save Originals: Before you embark on the resizing process, make a copy of the original image. This ensures that you always have access to the highest quality version, and any mistakes during resizing won’t affect your original asset.
