Photos are an integral part of the business world, and most people have to send them in emails, upload them to the company's blog or to an Amazon page. Photos are often too large to be uploaded or sent to anyone, which is the reason why non-professional photo editors frequently need a simple and easy way to resize a large number of images.

Most people think that in order to resize images you need to have a professional photo editing software, but in this article, we will show you how to resize images with apps that are already available to you on your Mac.

Method 1: Resize Images on Mac with Preview app

Regardless which version of Mac's operating system you have, Preview app is probably the quickest and the easiest way to resize images, since this app is available in all iterations of Mac OS and Mac OS X

Resize a single photo on Mac with Preview App

This app is often a default photo viewer on Mac computers so in order to open your photo in Preview app you just need to find the folder in which it is stored and double-click on it. Once the photo is displayed in the Preview app, click on the Tools menu and select the Adjust Size option.

Before proceeding to resize your photo, make sure that Scale Proportionally option is activated in order to ensure that the proportions of the photo remain unchanged. You can also choose whether you want the size of the picture is to be displayed in pixels, inches, centimeters or percentages and then just change the values in the Height and Width boxes. If you like the results you got, go to the File menu and click Save As option to finalize the process of resizing your photo.

It often happens that you need to resize more than just one photo, so instead of changing the size of each photo separately, you can resize as many photos as you want simultaneously in the Preview app. In order to start the batch resizing process, you first need to select all the photos you want to resize in the folder in which they are stored and then open them in the Preview app. After the photos are displayed in the app, go to the Edit menu and click on the Select All option.

Head over to the Tool menu, and select the Adjust Size feature. Change the values in the width or heigh boxes and make sure that the Scale Proportionally box is checked. Finally, go to the File menu and click on the Save As option to save the resized photos.

It is worth noting that the names of the commands may vary on different versions of Mac OS, but the batch resize process we described works on OS X Yosemite, Snow Leopard or any other Mac OS.

Method 2: Resize images through e-mail

All Mac computers have the E-mail app that allows its users to change the size of images before sending them. This app provides probably one of the fastest ways to resize images since all you have to do is drop the photo into the E-mail app, and select which picture size you want to use. Small, Medium or Large sizes are available, but in order to gain access to the resized image, you first need to send it. The app won't allow you to drag the resized photo from drafts, which means that E-mail app can't be easily used for resizing photos you want to upload on your blog or a social media account.

Method 3: Crop and Resize Images on Mac with Preview

Changing the number of pixels a photo has isn't the only way to resize an image. Cropping is also a great way to change the size of a photo because it also allows you to remove parts of an image you don't like. Here's how you can crop a photo in Mac's Preview app

Step 1

Double-click on the photo you want to crop, in order to open it in the Preview app, and then click on the Markup icon to access the photo editor.

Step 2

Once the Markup toolbar appears, click on the dotted rectangle icon, and select the Rectangular Selection option from the drop-down menu. The crop rectangle will appear on the photo, and you need to drag one of its sides in order to designate the area of the photo you want to crop. https://coolufiles457.weebly.com/play-free-slot-machines-online-with-no-download.html.

Step 3

Click on the Crop button located in the upper right corner of the screen to remove and resize your photo. In the end, go to the File menu, and click on the Save As option to save the photo you cropped.

The image size (or pixel dimensions) of an image is a measure of the number of pixels along an image's width and height. For example, your digital camera may take a photo that is 1500 pixels wide and 1000 pixels high. These two measurements indicate the amount of image data in a photo and determine the file size.

Resolution is the amount of image data in a given space. It is measured in pixels per inch (ppi). The more pixels per inch, the greater the resolution. Generally, the higher the resolution of your image, the better the printed image quality. Why cant i play minecraft on my mac. Resolution determines the fineness of detail you can see in an image.

Although a digital image contains a specific amount of image data, it doesn't have a specific physical output size or resolution. As you change the resolution of an image, its physical dimensions change, and as you change the width or height of an image, its resolution changes.

You can see the relationship between image size and resolution in the Image Size dialog box (choose Image > Resize > Image Size). As you change one value, the other two values change accordingly.

The Constrain Proportions option lets you maintain the aspect ratio (the ratio of image width to image height). If you select this option and change the image size and resolution, the image does not stretch or shrink.

The Resample Image option lets you change the size of an image without changing the resolution. If you need to print at a specific resolution, or at a smaller or larger resolution than the current image allows, resample the image. However, resampling can degrade image quality.

Your monitor's resolution is described in pixel dimensions. For example, if your monitor resolution is set to 1600 x 1200 and your photo's pixel dimensions are the same size, at 100%, the photo will fill the screen. The size an image appears onscreen depends on a combination of factors: the pixel dimensions of the image, the monitor size, and the monitor resolution setting. In Photoshop Elements, you can change the image magnification onscreen, so you can easily work with images of any pixel dimensions.

How To Edit Pixel Size On Mac

When preparing images for onscreen viewing, you should consider the lowest monitor resolution that your photo is likely to be viewed on.

Click-hold the file information box at the bottom of the document. The box displays the width and height of the image (in pixels, and in the unit of measurement currently selected for the rulers), the number of color channels, and the image resolution (ppi).

• Select the Hand tool or Zoom tool, and click Print Size in the Tool Options bar.
• The magnification of the image is adjusted to display its approximate printed size, as specified in the Document Size section of the Image Size dialog box. Keep in mind that the size and resolution of your monitor affect the onscreen print size.

Change print dimensions and resolution without resampling

You might need to change the print dimensions and resolution if you are sending the image to a print shop that requires files to be at a specific resolution.

If you are printing directly from Photoshop Elements, you don't have to perform this procedure. Instead, you can choose a size in the Print dialog box and Photoshop Elements applies the appropriate image resolution.

Note:

To change only the print dimensions or the resolution, and adjust the total number of pixels in the image proportionately, you must resample the image.

Make sure that Resample Image is deselected. If deselected,you can change the print dimensions and resolution without changingthe total number of pixels in the image, but the image may not keepits current proportions.

Note:

Resample Image must be selected in order to use the Constrain Proportions and Scale Style functions.

To maintain the current aspect ratio, select ConstrainProportions. This option automatically updates the width as youchange the height, and vice versa.

Under Document Size, enter new values for the height and width. If desired, choose a new unit of measurement.

For Resolution, enter a new value. If desired, choosea new unit of measurement, and then click OK.

Note:

To return to the original values displayed in the Image Size dialog box, use Alt (Option in Mac OS) + click Reset.

Changing the pixel dimensions of an image is called resampling. Resampling affects not only the size of an image onscreen, but also its image quality and its printed output—either its printed dimensions or its image resolution. Resampling can degrade image quality. When you downsample, meaning that you decrease the number of pixels in your image, information is removed from the image. When you upsample, or increase the number of pixels in your image, new pixels are added based on the color values of existing pixels, and the image loses some detail and sharpness.

To avoid the need for upsampling, scan or create the image at the resolution required for your printer or output device. If you want to preview the effects of changing pixel dimensions onscreen or print proofs at different resolutions, resample a duplicate of your file.

Note:

If you're preparing images for the web, it's useful to specify image size in terms of the pixel dimensions.

Select Resample Image, and choose an interpolation method:

Fast, but less precise. This method is recommended for use with illustrations containing edges that are not anti-aliased, to preserve hard edges and produce a smaller file. However, this method can create jagged edges, which become apparent when distorting or scaling an image or performing multiple manipulations on a selection.

Medium-quality.

Slow, but more precise, resulting in the smoothest tonal gradations.

Use when you're enlarging images.

Use when you're reducing the size of an image. This method maintains the detail in a resampled image. It may, however, oversharpen some areas of an image. In this case, try using Bicubic.

To maintain the current aspect ratio, select ConstrainProportions. This option automatically updates the width as youchange the height, and vice versa.

In Pixel Dimensions, enter values for Width and Height.To enter values as percentages of the current dimensions, choosePercent as the unit of measurement.

Click OK to change the pixel dimensions and resamplethe image.

Note:

For best results in producing a smaller image, downsample and apply the Unsharp Mask (Enhance > Unsharp Mask). To produce a larger image, rescan the image at a higher resolution.
