Steps Used In Successfully Resizing The Size Of The Images (Pre)

Once you open the GNU Image Manipulation Program, the following steps will be conducted.


Step 1 - First, you need to click from the menu on File & then press Open. Alternatively, you can press Ctrl+O.


Step 2 - Now, navigate to the File from the Places section and click on Open.


Step 3 - A dialogue box will appear, prompting whether you want to Convert to RGB Working Space. You can easily choose Rendering Intent with Relative colourimetric, Perceptual, Saturation or Absolute colourimetric. If you like the colours already in the original image, you need to choose and click the Keep button at the bottom.


Step 4 - Your original uploaded photo will appear in front of you. To resize this photo, you need to click right on the Image tab & then select the option of Scale Image.


Step 5 - In this step, after selecting the Scale Image, you have to select the px if you are planning to upload the images on the website. Now, you will have to choose the size in height and width. You can resize the images for your website or blog post.

The maximum width of a picture can be 800 px. You should keep in mind that the lower the pixel of an image, the image size will be lesser accordingly. The height of the image will be adjusted in a perfect ratio automatically.

Similarly, in case the image is in portrait form, the lessening of the height should be preferred. Usually, the height that you should pick is 300 or 400 px. Once you have finally selected the value of px (either height or width), you should click on the px button so that the other values get adjusted in a proper aspect ratio. Usually, the values are 800px for width, and the height is 600px.


Step 6 - In this step, you will see a small preview of the resized image. However, this is not the final image size. You can change the value from 25 -100 per cent.


Steps For Successfully Exporting The Resized Image (Post)

Step 7: By now, 80 percent work is completed. Now, it is time to press on the File tab & then press the tab Export As. Then you will have to name the File or leave it as it is and replace it with a larger one; if you do not wish to use the same as the original size & then click on export.


Step 8: You can make changes if you like playing with the given settings. Using the first Quality tab, you can lower the image size, etc. Once you click on this Export button, your exported File will reach the mentioned location.


If you follow the above-discussed eight steps successfully, you will face no issues. The steps shared here will work effectively on Windows, Linux and Mac.
