After a short investigation, we came to a conclusion that the questions of resizing perplexe a lot of the users, as they do not understand the reasons for this as well as they are frightened of very complicated Maс resize images solutions. Nevertheless, even difficult things can be easier as it seemed at first sight. So, to know more about 'What is resizing?' and 'How to resize photos on Mac?' read below.

Understanding the term and the reasons for resizing photos

Under the term resizing we indicate a decrease or increase (although the latter is not welcomed) of the size of the photo in pixels. Usually, it is done proportionally and basically is used to create a 'preview'. In other words, a lightweight version of a photo for quick loading. Nevertheless, the reasons for bulk resize images cannot only be narrowed down to just a quick loading of the images. One can face such a necessity due to other different reasons. We have gathered the list of common reasons for the resizing of an image. Look at it:

  • Very often we are faced with the task of creating and sending via the email a photocopy of the document. How to do it right? How to form a document convenient for sending and receiving? What requirements should it meet? You may say that, the solution is obvious – to photograph or scan the necessary paper, save the image on the computer and then attach it to the letter, as a normal attachment. The only problem arises – the impressive size of the resulting file, as modern cameras make photos ranging from 1.5 to 7-9 MB, which is absolutely not suitable for sending by mail. Even more, receiving a large file is very difficult, and sometimes impossible at all with the slow or unstable Internet. Besides that, the transfer of a large image can cause the recipient's mailbox to overflow, after which it will not be able to receive mail at all until the recipient cleans old messages. In addition, a large photo is often impossible to get by using email programs because of the time limit for connecting to the server. A letter with a bulk attachment does not have time to fully load. As a result, the connection is interrupted until the next attempt. And so again and again. The last but not the least, even if the image was obtained, it is so large that it does not fit on the screen entirely, and only a small fragment of it is visible. In either case, the outcome is sad – the recipient cannot receive or see the sent material. And in the worst case, the work of the mail is paralyzed. Here, the understanding of how to resize an image on Mac can be rather useful.
    Also, when sending images by the email you should keep in mind the following rules of network ethics:
    • • the photo should clearly display the information which you want to give to the recipient;
    • • always aim to send a picture as small as possible. Do not send without the need letters with a total attachment of more than 500-700 KB. If there are a lot of attachments, send several letters with several attachments in each;
    • • the image should be placed on the screen of the recipient. It is convenient when the photo size is 600-800 pixels (points) along the long side;
    • • at the same time, its size will vary from 50 to 120 Kb, which is very convenient both for sending and receiving.

  • Next case is the following. Often we store a large volume of different photos on a home computer. However, with a good camera these photos take up a large amount of memory on the hard drive, and not always you need the original photos, so there is some sense in keeping them in a reduced form, which in most cases is not even will be noticeable for the eye, but noticeable in the size of the hard drive. And here again knowing how to resize multiple images will come to rescue.

  • The mentioned above case, when photos should be resized to the optimal size because of the rules of the resource where it is supposed to be posted, for instance: a blog, an article, a photo report, etc.

  • There are situations when you are required to provide photos of a certain size or upload photos to the resource with the limits of PX (or as it is also known as pixels).

As you see, there are a lot of reasons why to resize images. And bearing the above information, you see, that it plays an important role and to know how to resize multiple images at once can bring even more benefit than resizing images one by one. While resizing the image, you change its resolution. The smaller resolution is, the smaller the size is. In addition, while resizing to a smaller resolution, you can increase image definition that can be rather helpful in some cases.

One can bulk resize images in 2 ways: by changing the algorithm according to which the photo is saved (the smaller the algorithm, the smaller the photo); changing the resolution (the number of pixels) of the photo. Whatever reason for resizing you have, either sending by email, saving space on your hard disk, providing a photo of a certain size or optimal size the question is the following how to choose the right resize image Mac solution?

Here's a great Markup Hero hack I've been using lately. I often find myself wanting to send several images via a single share link to someone. This article explains how to do it and why you would want to.

Here's a use case:

Quickly Resize Images Mac Os

  1. I'm on a customer service chat with REI regarding some clothes they sent me that were damaged
  2. I take four pictures of the damaged clothes on my iPhone and save them to my downloads folder on my Macbook
  3. I've got my iPhone photo preferences set to take pretty high res images so the pictures are huge, about 5-6MB each
  4. Although Markup Hero has an 8MB limit per image, I really don't want to send 6MB files in a customer service chat, even if I'm just sending a single Markup Hero link
  5. I go to my Mac finder > downloads folder and highlight the four files
  6. Right click and choose Resize Image (800px) which automatically compresses each image to 800 pixels, about 100K each (down from 6MB each)
  7. I drag the four files into Markup Hero and copy the share link
  8. Done.

Now I just send the share link to the REI customer service person and in one click, they see all my images. Fast and easy.

How to Setup Image Resizing with One Click from a Folder in Mac Finder

Of course there are a ton of ways to resize images on your Mac. You can use Photoshop and a number of other design programs and even Mac's built in Preview app. But it takes time and you have to do it one by one or setup a batch process. Not fast. The method described below will take you 5 minutes to setup and then re-use it over and over again. Here's how to do it.

1 — Launch the built in Mac program called Automator (it's in the Applications folder, or press CMD + Space Bar and just search for Automator)

2 — Once open, Automator should automatically create a New Document, if not just choose to create one

3 — Choose the Quick Action document type

4 — Choose Image Files in the workflow receives dropdown, select Files and Folders in the Actions sidebar, then drag Get Specified Finder Items to the workflow area.

5 — Select Photos in the Actions sidebar, then drag Scale Images to the workflow area.

6 — Automator will pop a confirmation window you to add a Copy Finder Items Action to give you the option to save a copy of the file in a separate folder. Choose Add if you want to do this, or choose Don't Add if you just want the images to update and overwrite themselves; that's what we choose.

7 — Then in the Scale Images action panel, type the width that you want to resize your images to. We chose 800, but you can make as many of these as you want for different sizes.

8 — Then save the automation by going to the Automator menu bar, select File -> Save, call your new service Resize Image (800) or whatever you like, and click Save. Mac unzip multiple zip files.

9 — To use your new automation, just go to finder, right click on the image or group of images you want to resize, choose Quick Actions -> Resize Image (800)

Create a Multi-Page Markup with Your Newly Sized Images

Now that you've got the quick resize automation setup, now just highlight any images you resized and drag them into Markup Hero to create a new markup with each image as a separate page. Copy the share link and send it to whoever you want.
