Do you have a photo that is too large to email or put on your website? Resizing your photo on a Mac is a quick and easy process that can help with this issue. No matter what type of Mac you have, this process should work for you.

To begin, double click on the photo you want to resize. If you’re using a mouse, left-click twice. Once the photo is open, click on “tools” and go to “adjust size.” Here, you will see the width and height of the photo in pixels. If you see the percentage, click on it once and change it to pixels.

Next, you will want to adjust the width and height to your desired size. Keep in mind that you don’t want any photo to be over 1 MB in size. For a photo to be put on a website, it should be around 600 pixels. However, 800 pixels is also acceptable. If you’re unsure, you can experiment with different sizes.

After you’ve adjusted the size, click “OK.” Don’t worry if the photo appears too small, as this is just the computer showing you how small it is in comparison to its original size. Click “file” and then “save” to save the resized photo.

That’s it! Your photo is now resized and ready to be sent or uploaded. It’s important to note that when you reopen the photo, it may appear larger than it did when you adjusted the size. However, it is still the correct size that you chose.

Resizing photos on a Mac is a simple process that can save you time and frustration. Give it a try and see how much easier it is to send or share your photos.
