Be it a beginner or a pro, SEO optimized image is what helps them in contributing to the ranking of their respective blog post.

But for a beginner Photoshop can be really costly. “I was also that beginner”.

So today I will give you a guide on how to use Gimp to create a SEO optimized image.

First let me give you a brief idea on SEO Optimized image:

For a SEO optimized image-

  • The color profile must be sRGB.
  • The Aspect Ratio must be-
    • 1:1 ,1080×1080, optimal for mobile screens and web.
    • 3:2, 1080×720, optimal for mobile screens and web.
    • 4:3, 1280×720, optimal for mobile screens and web.
    • 16:9, 1920×1080, optimal for website background image.
  • The File Type must be-
    • PNG: for good quality images + large file size (when every detail matters).
    • JPG: for Good quality images(not as good as PNG) + small file size.
    • Gif: for animations.
    • SVG: for vector images.
  • The File Size must be-
    • Photos to be used in blog post should be each of <70kb.
    • Background image of an website <500 or <1000kb.
  • Save Files using hyphens instead of space. Example: “blog-it-big.jpg”.

Steps for Resizing, Aspect Ratio and other criteria for SEO Optimized image using Gimp(free tool) are:

1. Select a Picture and open through Gimp software.

2. A box will appear in the window. It will ask that whether you want to convert the colour profile to Gimps built-in sRGB color profile.

If your colour profile isn’t sRGB then you should definitely convert it otherwise I don’t think its required.

So, lets keep it the way it is and select “Keep”.

7. Here you can change the height width in pixels, percent, inches, centimeters, millimeters etc.

Also you can change the resolution in pixels/in, pixel/pt, pixel/cm etc.

Now lets change the width to 1080px. You can see the moment you either change the width or the height, the former always adjusts to the later accordingly.

8. Since adjustments may not be appropriate to that of the SEO, we will set the aspect ratio as discussed above.

Few things that you should notice is:

  • Fixed …..Aspect Ratio (if don’t see Aspect Ratio you can click on the down arrow sign and select it from there).
  • 1:1 – This is where you set your aspect ratio.


You have to set your aspect ratio manually. No dropdown list of different aspect ratio is being provided like Adobe Photoshop.

  • Position represents the position of your cursor.
  • Size- You can input positions as per your choice. To achieve more flexibility disable the fixed option by clicking on the “x” symbol.

Lets set the aspect ratio “1:1”. and crop the image.
