How to Increase Pixels in Digital Pictures

Increasing the pixel count of a digital picture, often referred to as “upscaling” or “resampling,” involves enlarging the photo while adding extra pixels to fill in the gaps. However, it’s crucial to understand that while you can increase the pixel count, you cannot genuinely add more detail to the image. Instead, upscaling tools use algorithms to guess what the enlarged image should look like.

Here’s how to upscale or increase the pixels in digital pictures using various methods:

1. Using Graphic Software (e.g., Adobe Photoshop):

  • Open the image in Photoshop.
  • Go to the Image menu.
  • Select Image Size.
  • Uncheck “Resample” to adjust dimensions without changing pixel count (just DPI). If you want to increase pixel dimensions, ensure “Resample” is checked.
  • Increase the width and height values or input a new resolution.
  • From the “Resample” dropdown, choose an algorithm. “Preserve Details 2.0” is a newer option that often produces better results.
  • Click OK.

2. Using Free Software (e.g., GIMP):

  • Open the image in GIMP.
  • Navigate to Image > Scale Image.
  • Input the new dimensions.
  • Under “Interpolation”, select “Sinc (Lanczos3)” for better quality.
  • Click Scale.

3. Online Tools:

  • There are various online platforms like “Let’s Enhance,” “BigJPG,” and others that offer image upscaling.
  • Upload the image to the platform.
  • Choose the upscale settings, if available.
  • Download the upscaled image.

4. Dedicated Software:

  • Some software solutions, like “Topaz Gigapixel AI,” utilize artificial intelligence to upscale images while preserving (or even enhancing) details.
  • Open the software, import your image, select your desired settings, and then upscale the image.

Comparison Table:

Method Tool/Platform Advantage
Graphic Software Adobe Photoshop Advanced controls; Professional results
Free Software GIMP No cost; Good quality with proper settings
Online Tools Let’s Enhance, BigJPG Convenient; No installation required
Dedicated Software Topaz Gigapixel AI AI-enhanced upscaling; Can enhance details in the image

Important Note: Always keep an original copy of your image before making any changes. Upscaling can lead to a loss in perceived quality, introduce artifacts, or make images appear softer, especially if the upscaling ratio is high.
