Batch resize images in Photoshop Elements

before after2 e1315921474353 Batch resize images in Photoshop Elements

Some time ago I wrote a post on batch resizing images in Photoshop. You can find the link here: http://projectwoman.com/2009/09/batch-resize.html. I also wrote an article on resizing in Lightroom which you can find here: http://projectwoman.com/2009/10/resizing-images-in-lightroom-2.html.

Someone then wrote to me explaining that they are using Photoshop Elements and that the resize feature in Photoshop does not work in Photoshop Elements. They are correct, but there is a way of batch resizing in Photoshop Elements and here’s how to do it.

Step 1
In Photoshop Elements, choose File > Process Multiple Files. This opens the Process Multiple Files dialog.

step12 e1315921613421 Batch resize images in Photoshop Elements

Here you can select which images to process. You can select either a folder of images, all opened files or you can click import and import images from an external device such as a camera card.

Typically, the best option will be to place all the images in a folder and process the files from that folder. To do this, click the Browse button opposite the Source box and choose the folder to process. Enable the Include All Subfolders checkbox if desired.

Step 2
Select the destination folder for the resized images (you can create one from this dialog), or, if desired, select Same as Source.

In the file naming area, select Rename Files if this is desired. You can then choose the naming convention such as typing a document name and the sequential numbering system to be used.

step22 e1315921631929 Batch resize images in Photoshop Elements

Step 3
In the image size area, select Resize Images as that’s what we came here to do.

Select Constrain Proportions as you will want your images to be resized in proportion and not skewed or distorted out of shape.

Now type the largest Width or Height to use for your resized images. If you enter 600 for the Width you will be unable to enter a value for the Height and vice versa. This is because you can only set one value – width or height (in this situation this resizing tool works differently to the corresponding tools in Photoshop and Lightroom).

So if you enter, for example, 600 as the Width all images will be sized so their width is 600 and their respective heights will be adjusted in proportion. Portrait images will be taller than 600 pixels and Landscape ones will be shorter.

Here too you should set the resolution for the images. If you plan to send your photos to an online sites for printing, you may want to match the resolution to what that site requires. For the web select 72 dpi.

step32 e1315921644592 Batch resize images in Photoshop Elements

Step 4
To convert the files to a different format or to compress them, from the File Type dropdown list, select the file format to use. For JPEG format images, you can choose Max, High, Medium or Low quality.

step52 e1315921669302 Batch resize images in Photoshop Elements

Step 5
You can also apply a Quick Fix to your images as you process them. These fixes include Auto Levels, Auto Contrast, Auto Color or Sharpen.

You can also apply Labels to your image such as adding a watermark or caption by configuring the options in the Labels area.

When you are done, click Ok to process the folder of files or the group of files that you had selected for processing.

step61 e1315921681382 Batch resize images in Photoshop Elements

Tip
If you want to resize images so their longest edge is a set value such as 600 then you will need to presort Landscape and Portrait images into separate folders and process them separately.

Resizing images in Lightroom 2

lr leadImage 719908 Resizing images in Lightroom 2
One of the hardest things for a new Lightroom user to work out how to perform is a simple image resizing. Look as hard as you like and there simply isn’t a resize menu command. There is, of course, a way to resize images and it is done as you Export them from Lightroom which makes sense when you know how Lightroom works but if you’re a new user it’s just plain confusing.

So, here’s how to batch resize in Lightroom:

lr 1 727623 Resizing images in Lightroom 2
Step 1
Select the Library module and select the images to export. Choose File > Export.

lr 2 727645 Resizing images in Lightroom 2
Step 2
The Export dialog gives you a series of choices for the exported images. Start by selecting where the exported images should be stored. Choose either a specific folder or the same folder that the originals are stored in.

To place the images in a subfolder of your chosen folder, select Put in Subfolder and type the name of a new subfolder to create. If you want the exported images to be available in Lightroom, select the Add to This Catalog checkbox. From the Existing Files dropdown list, choose what to do if files of the same name appear already in the selected folder.

lr 3 705178 Resizing images in Lightroom 2
Step 3
From the File Naming options select what you want your files to be named.

For example, selecting Filename will give the files the same name as the original images. Custom name – Sequence lets you give the files a custom name and Lightroom will add a sequential number to each file. Type the Custom Name in the Custom Text box.

You can also select Edit from the dropdown list and create your own file naming template.

lr 4 705187 Resizing images in Lightroom 2
Step 4
In the File Settings area, select the export format such as JPEG for the web and the Quality – the higher the quality, the larger the file size.

In the Color Space area choose sRGB for the web.

lr 5 757372 Resizing images in Lightroom 2
Step 5
In the Image Sizing area set the file size and resolution. So you can, for example set the Resolution to 72 pixels per inch for the Web or 300 ppi for printing.

To size the images, enable the Resize to Fit checkbox. By selecting Dimensions you can set the final dimensions for each image such as 800 x 1200 and the images will be sized as close to this as they can be given their current aspect ratio. They won’t be larger than this and one measurement at least will be 800 or 1200. Lightroom does this regardless of whether the images are in Portrait or Landscape orientation so portrait and landscape images will end up the same sizes.

If you select Width & Height you can set the longest dimensions of each image in each direction. All images will be sized so their Width is no larger than the value you set and their Height is no larger than the value you set – the same width and height values are applied to portrait and landscape images so a Width of 400 and Height of 600 will give a larger portrait image than it will a landscape one because the landscape image can’t be wider than 400, forcing its height to much less than this.

The Long Edge and Short Edge options let you set the maximum length of the long or short edge of a photo – so Portrait and Landscape images are treated alike here.

If you enable the Don’t Enlarge checkbox you could have images much smaller than your selected dimensions if the originals are already under the selected size.

lr 6 757391 Resizing images in Lightroom 2
Step 6
You can apply sharpening by selecting the Sharpen For checkbox from the Output Sharpening options and select to sharpen for Screen, for example, and set a Low, Standard or High Value of sharpening.

In the Metadata area, select to add metadata if desired and from the Post-Processing options select what to do with the images afterwards, for example you could open the images direct in Photoshop or in an alternate editor or another application or show them in Windows Explorer.

When you’re done with the selections, click Export and the selected images will be exported.

lr 7 719875 Resizing images in Lightroom 2
Step 7
If you’ll use these settings again, save them to use next time by clicking the Add button at the foot of the Preset list, type a name for the preset, select the folder to add the preset to or just leave it set to User Presets and click Create.

In future, you can return to the Export dialog and select these options by clicking the Preset name. You can still make changes to the settings, if desired, and export a new set of images.

Batch Resize

ps before after 786702 Batch Resize
While it’s relatively easy to write an Action to resize a series of images in Photoshop, it’s easier still to get Photoshop to do all the work for you. Photoshop comes with an image processor script that will open, resize and save a series of images for you – very quickly.

ps step1 786735 Batch Resize

Step 1
Choose File > Scripts > Image Processor. The image processor dialog shows a simple four-step process for resizing the images.

ps step2 743580 Batch Resize

Step 2
In Step 1 of the dialog, select to either resize the images already open in Photoshop (if you have them open), or click Select Folder and select a folder of images to resize. Select Include all Subfolders to include all subfolders of the selected folder.

ps step3 743609 Batch Resize

Step 3
In Step 2 of the dialog select where to save the images. If you select Save in Same Location Photoshop creates a subfolder in which to save the images so you don’t have to worry about overwriting them. If a subfolder by the same name already exists with images with the same names in it, Photoshop saves to that folder but adds a sequential number to the file so you still won’t lose your files. Alternatively, you can select a different folder for the resized images.

ps step4 796454 Batch Resize

Step 4
In Step 3 of the dialog select the file type to save in. For the web Save as JPEG is the obvious choice. Set a Quality value in the range 0 to 12 where 12 is the highest quality and 0 the lowest. For better color on the web, select Convert profile to sRGB and ensure that Include ICC Profile at the foot of the dialog is checked so the profile will be saved with the image.

To resize the images, select the Resize to Fit checkbox and then set the desired maximum width and height for the final image. For example, if you type 300 for the width and 300 for the height, the image will be resized so that the longest side of any image, whether it be in portrait or landscape orientation will be 300 pixels. The images are scaled in proportion so they won’t be skewed out of shape.

The Width and Height measurements do not have to be the same so you could, for example, specify a Width of 400 and a Height of 300 and no image will have a width greater than 400 or a height greater than 300.

ps step5 796484 Batch Resize

Step 5
If desired you can save in another format as well by selecting its checkbox so you can save the same image in different formats and at different sizes in the one process. You can also select to run an Action on the images, if desired.

When you’re ready, click Run and the images will be automatically opened (if they are not already open), resized, saved and closed.

To see your resized images, choose File > Open and navigate to the folder that you specified the images to be saved to. If you chose to save as JPEG, the images will be in a subfolder called JPEG, for PSD in a folder called PSD and so on.

So whenever you need to resize a lot of images for uploading to the web, for example, the Photoshop Image Processor script makes the job almost painless.
