The Challenge of Image Resizing

Resizing images seems simple, but doing it incorrectly can result in blurry, pixelated, or distorted images. Understanding the principles behind image resizing will help you maintain quality every time.

Downscaling vs Upscaling

Downscaling (making images smaller) almost always preserves quality well, as you are reducing data rather than creating it.

Upscaling (making images larger) is more challenging because the software must create new pixels that did not exist in the original.

Best Practices

• Always start with the highest resolution original available.
• Lock the aspect ratio to prevent distortion.
• For web, resize to the exact display dimensions needed.
• Use bicubic resampling for photographs (smoother results).
• Save resized images as new files; keep the original intact.
