With some of these options you can also adjust quality (and therefore size).From the Format dropdown many choose either HEIC (the new file format), JPEG, JPEG-2000, OpenEXR, PDR, PNG or TIFF.To change the file format click on File in the menu.We touched on this earlier when we discussed reducing the file size as some file formats are smaller than others. Speaking of saving what if you want to change the file format of the image. Now press Command + S to save (or File > Save) and all your images will be saved with the new dimensions.Click OK to adjust the size of the selected images.If you want them all to be 1000 pixels wide, type 1000 in the Width box.

You will see Multiple Values appear as the measurement in the columns (assuming all the images are different sizes).If you are just adjusting width or height don’t forget to select Scale Proportionally.

Now go to Tools > Adjust Size (as we did earlier).

Select all by pressing Command + A (or choose Edit > Select All).

Right click and choose Open with Preview.

Select all the images you want to resize by clicking on each one in the Finder, or on your Desktop, while pressing the Command key.

HEIC files are half the size of a JPEG but offer the same quality. However you could choose HEIC, which is a space saving file type (it stands for High Efficiency Image Format) that should create an image that is smaller than a JPEG, but with the same quality. You can’t add pixels to an image so the only way to make an image larger without losing quality (which is determined by the number of pixels in a square inch) is to crop the image following the instructions above.

Once you are happy click command + K and that will crop the image.

Once you have the correct sized box un-click the mouse, and you’ll be able to move the box to prime position.

You will see a little counter in the bottom right corner that shows how many pixels are selected.

If you want the image to be a particular size, like 1,600 x 900 in the example above, you can drag the box to the dimensions you need.

Click on the image in Preview and drag so that the blue box surrounds the part of the image you want to crop.

If you want to crop an image it’s not immediately obvious how to do so because there isn’t a traditional crop tool in the menu, but it’s actually very easy. If you are trying to shrink the image to 500KB for example, you can keep adjusting until you are happy with the result here. (It may take a while to calculate the size.) If you open the Adjust Size menu as above you will notice that when you adjust the dimensions of the image you will see a preview of the size (in MB or KB) of the image before and after you have make your changes. If you are trying to make the size of the image smaller (perhaps so you can send it via email) there are a couple of ways you can do so. But what if it’s the size of the image – in terms of MB – you want to change? How to make an image smaller That will change the dimensions of the image, perhaps you need the width to be the same as the width of a webpage you are adding the image to, for example.

Adjust either the Width number or the Height number – the other will automatically adjust proportionally.

Choose whether you want to resize according to pixels, percent, inches, cm, mm or points.

This means you can only change one dimension, length or width, but it means everything will be adjusted equally.

Now, assuming want your image to look the same after – rather than stretched or squat, you need to make sure that Scale proportionally is selected.

Choose Adjust Size (you can also open this menu by clicking on the square with arrows icon in the menu bar).

Double click on the image – this should open the image in Preview, if it doesn’t, close it and right click to choose Open With and select Preview.

Locate the image (either using the Finder, or on your Desktop).
