Step 1: Prepare all the photos that need resizing. I highly recommend keeping all the photos in one folder. When you're downloading photos from Dropbox, for instance, choose the images that you're going to use and download them all at once. You'll save a lot of time and storage space this way. In the Preview app on your Mac, if the Markup toolbar isn't showing, click the Show Markup Toolbar button, then click the Adjust Size button. Enter new values for width and height, or click the 'Fit into' pop-up menu and choose a size. Resize the image by a percentage: Choose 'percent' from the pop-up menu next to the Width and Height fields, then enter the percentage in those fields.
Batch photo edits made easy- All these tasks are easily accomplished using Preview, Mac's default application for viewing images. Use Mac's Preview App to Resize Images. Open the image in Preview, and open up the Markup Toolbar by clicking the toolbox icon from the main toolbar. Next, click the resize icon.
- Whether you want to save room in your saved photos folder, or you just want a social-media friendly picture, resizing photos can help you manage your visual media. Here's everything you need to know about resizing photos on a Mac, whether you're applying it to one photo or many. Check out the products mentioned in this article: MacBook Pro (From $1,299 at Apple) How to resize images on Mac.
- When managing images on your Mac, your best bet for built-in options will be Apple's Preview program. While simple, this program offers some quick ways to crop, resize, annotate, and otherwise edit images.
Images don't always come in convenient sizes. Whether you've downloaded one from the web or taken one yourself in the hopes of using it for a project, resizing it to fit certain guidelines is often required.
However, aspect ratios are not the only concern. If we want to share the image via email campaign, use it on social media, or include it in a presentation, it needs to be small enough in file size, so it doesn't create unnecessary problems for other people's network connections and machines. Try emailing a 50 MB PDF file around the office and see the reaction that follows.

How can you quickly change the size of an image and optimize it at the same time? Read on in our brief guide for manipulating images on your Mac.
How To Resize Images On Mac
You have two easy options that allow you to resize images on Mac: either using the default Preview app or more advanced PhotoBulk.
Preview is built right into your Mac and mostly used for viewing images. But it's also a feature-rich tool for manipulating images, including changing their size. Preview lets you control every detail, from the number of pixels to the dimensions in inches. You could also choose to transform the image as a percentage of the original or go completely custom. Finally, the app gives you an option to modify images according to a range of preset sizes, such as 640 x 480 pixels.
Here are the steps to resize an image in Preview:
- Open the image you want to modify
- Click on Tools and select Adjust Size
- Now you can adjust the Width, Height, and Resolution
- Once you've made those changes, make sure you've ticked the 'Scale proportionally' box; otherwise you risk an image that is out of proportion and may not look very professional
Now the resized image will show in the Preview window, and you can keep trying out new sizes until you are happy with the end result. Go to File > Save to save the image with the original name or File > Rename if you want to keep the original (useful if you need to keep a high-resolution version) and apply a different name to this copy.
With Preview, you can also change the file format. Under File > Export, you have the following options: PNG, JPEG, JPEG-2000, OpenEXR, PDF, or TIFF. Some of these could potentially improve the quality of the formatting as well.
Bulk resizer for Mac
Mac Image Resize Tool
PhotoBulk is a life-saver for when you need to change the size of multiple images. Drop them into the app and resize in a sec.
Another option is to use PhotoBulk, an image editor designed specifically for bulk resizing, but which can also be used to resize individual images. PhotoBulk puts all of the menu options in one convenient window, along with a real-time preview feature and the option to apply watermarks at the same time.
To resize an image with PhotoBulk:
- Open up the app
- Drag and drop your image onto the window
- Check Resize option from the left-side menu
- Select the type of resizing you need
- Click Start
Resize multiple images at once
Sometimes you need to resize multiple images at once. Although probably not your best option, Preview does allow for batch resizing:
- In the folder with your images, select the ones you need to resize and then right-click on them, and choose Open With > Preview. This will open them all in Preview's left sidebar.
- Select all the images inside Preview (shortcut: Cmd + A) and then go Tools > Adjust Size, just like in the steps outlined above
- When done, choose to either Save or Rename and then Save
The downside of using Preview for batch resizing is that you have to process all the images at the same time. PhotoBulk, on the other hand, provides much more control and the ability to modify the size of individual images without needing to apply those same dimensions to every image:
- Drag and drop a bunch of images into PhotoBulk
- Check the Resize box
- Use the dropdown menu to adjust images according to width, height, etc.
- In the same area, you can choose to rename files and their formats, as well as add a watermark if needed
Overall, whichever option you choose for resizing images, Preview or PhotoBulk, it should now be fairly easy for you to do so. Your best bet is probably to use Preview for single images and PhotoBulk for multiples ones. Just make sure you input the right dimensions and don't forget to save the original if you need to keep a higher resolution version for later. Best of all, PhotoBulk is available for a free trial through Setapp, a platform of over 150 useful apps and utilities for macOS. Another trick up your sleeve.
Meantime, prepare for all the awesome things you can do with Setapp.

Resize Image Mac Os
Trick
Hey
If you ever need to work in design, whether it be web design, Photoshop work, or general image editing. You may need to resize an image. There ain't many methods which you can do it quickly and easily. I have found two methods, one has an awesome GUI (General User Interface) and the other is more script based.
Resize Image Windows 10
The first method uses an application called Resize ‘Em All. It appeared in my Top 100 Apps. Resize ‘Em All, gives you the ability to modify the image dimensions, rotation and the format. You can either drag or drop a file onto the drop zone or open them from File > Open.
Once you have opened an image or a group of images you get a range of options for you to apply to the image. This enables you to change the dimensions quickly an easily using the button and the text boxes. If you want to apply this to many images at a time there is a batch menu option in the menu bar. From here you can edit all of the images using the Batching > Edit Images. You can then hit the Batch > Save options to save all the images,
It runs surprisingly quick. Its a simple way to modify a whole range of images at once.
The next option is to use an Apple Script. I don't use many Apple Scripts but this is one that I use quite regularly. I think I originally found it here. Although I have had it on my system so long I can remember the original source.
Since the script is in text format you have to open this up in Apple Script. Go to Applications > Apple Script > Script Editor. Run windows programs on mac free download. Paste the following into the main pane.
-- save in Script Editor as Application
-- drag files to its icon in Finder
on open some_items
repeat with this_item in some_items
try
rescale_and_save(this_item)
end try
end repeat
end open
to rescale_and_save(this_item)
tell application 'Image Events'
launch
set the target_width to 120
-- open the image file
set this_image to open this_item
set typ to this_image's file type
copy dimensions of this_image to {current_width, current_height}
if current_width is greater than current_height then
scale this_image to size target_width
else
-- figure out new height
-- y2 = (y1 * x2) / x1
set the new_height to (current_height * target_width) / current_width
scale this_image to size new_height
end if
tell application 'Finder' to set new_item to ¬
(container of this_item as string) & 'scaled.' & (name of this_item)
save this_image in new_item as typ
end tell
end rescale_and_save
This should appear purple in the text box. Hit the compile button in the toolbar. It will run through the code checking for errors, there shouldn't be any. The result will be different coloured text based on the syntax.
There are two points in the code that you should be aware of. The first one is the new width of the image. This is represented by the following.
set the target_width to 120
If you want to change the size of the new output you can change this number to any size you want. The next piece of code you should be aware of if the output file name. This is represented by the following line.
(container of this_item as string) & 'scaled.' & (name of this_item)
Resize Image Size
The word you need to change is 'scaled.' this can be anything you want, I would recommend in keeping it down to one word. The extra dot is added so you can clearly see what the new file is.
The final stage is to save out the script. Go to File > Save and save the script as a script file. Name it 'Image Reszie Source' or anything you feel like. This is the source file incase you want to go back and change any of the variables. Then go to File > Save As again and change the file format as Application. This will save the script so that when you drag and drop an image onto it will run. Name this so the file size is in the file name. You can then go back into the code change the image size variable. I have about 5 or 6 files like this all this different sizes.
To run the script select the images you want and drop them onto the application script. The code will run and place the new files in the same folder. It is not as quick as Resize ‘Em but it is simpler.
Hopefully you have followed what I have said, if you have any problems just leave a comment and I will get back to you.
