When you’ve opened the file in Photoshop, you’ll see it appear on your screen, ready to be edited.

The ‘Image’ menu is where you’ll find all the options for adjusting the size and dimensions of your image.
Step 3: Select ‘Image Size’

Tips: Reducing the Size of a JPEG File in Photoshop CS5
- Before changing the size, make sure you have a backup of the original image, just in case.
- Consider the purpose of the resized image – if it’s for web use, a lower resolution might be acceptable.
- Use the ‘Save for Web’ option if you’re optimizing the image for online use, as it gives you more control over the final file size.
- Keep in mind that reducing the file size too much can result in loss of image quality.
- If you’re not sure about the new dimensions, you can always undo the changes in Photoshop and try again.
