To change the pixel size of a JPEG image, you can use various image editing software or online tools. One commonly used software is Adobe Photoshop, but if you don’t have access to it, you can use other alternatives like GIMP (GNU Image Manipulation Program) or online tools like Pixlr or Canva. In this example, let’s use the free online tool Pixlr.
1. Visit the Pixlr website (https://pixlr.com) and click on the “Open Pixlr Editor” button.
2. In Pixlr Editor, click on “Open image from computer” to upload your JPEG file. Alternatively, you can also open the image directly from a URL or from Pixlr Library if you have used it before.
3. Once your image is loaded, go to the “Image” menu at the top and select “Image Size” or press the shortcut key “Ctrl + Alt + I” (Windows) or “Cmd + Option + I” (Mac).
4. The Image Size dialog box will appear, displaying the current pixel dimensions of your image. You will see fields to enter new values for width and height.
5. Make sure the “Constrain Proportions” option is checked to maintain the original aspect ratio of the image. If you want to change the size proportionately, you can modify either the width or height, and the other value will automatically adjust accordingly.
6. Enter the desired pixel dimensions for the width or height (or both) of your image. You can enter the values in pixels or percentage.
7. Once you have entered the new dimensions, click on the “OK” button to apply the changes.
8. to save your resized image, go to the “File” menu and select “Save” or press the shortcut key “Ctrl + S” (Windows) or “Cmd + S” (Mac). Choose a file name and select the desired file format (JPEG is usually the default format for JPEG images) and click on the “Save” button.
By following these steps, you can easily change the pixel size of your JPEG image using the Pixlr online tool. Remember to save the resized image as a new file to avoid overwriting your original image.
