Photoshop :: Batch Resizing By Percentage
Dec 16, 2003
I'm looking for a way to resize a large number of images, but not to a specific size. Because of the vertical and horizontal orientation of my various photos, I want to be able to decrease the size of photos I won't be printing by a given percentage.

I have some hand drawn patterns that need resizing by percentage and printed. However, when I resize, it shows exactly the same and prints exactly the same.

After upgrading to Mountain Lion Photoshop CS4 won't allow batching several images to certain folders on our servers.
Photoshop message reads;
The destination is not writable (read-only).

This has been "bugging" me for a while.
1) Open a raw file (.CR2)
2) output the file to JPG or open directly
===> i.e. the resulting image is 3888 x 2592
3) use Automate > Fit Image
===> i.e. 1200 pixels (reducing the image by a factor of 3.24)
======> The result should be 1200 x 800 pixels
However the batch conversion would be result in 1200 x 801 pixel.
Even if I were to add a step 2.5 as follows
2.5) image > image size > 1200 x 800
After automate > Fit Image (1200) it would still result in 1200 x 801 pixels!
What's broken with photoshop?
The only fix I've stumbled across so far would be to use an external programme to strip all the exif and attached metadata, only then would the "Fit Image" script work.
Having one extra pixel doesn't really matter most of the times, but it's does get on my nerves.
Advice sought: How can I fix this?

There are seems to be a lot of ways to resize many pictures at once. However, I need to resize one picture into about 100 different sizes, then do the same thing to about 10 other pictures.

Photoshop CS2 & CS3 will not open my NEF raw files {Nikon D300}. Both versions have always opened my raw files. Also, CS3 locks up when I batch resize jpgs.

I want to resize dozens of jpeg photos so they are all the same size. Rather than doing them one at a time, is it possible to do them as a batch in PS CS5?

I will try and describe my situation regarding the manipulation of images that have various dimensions, and to downsize and down sample to a particular uniform size for all. After I can create this so called action, I will then use it to process thousands of images through batch processing.
Scenario:
- [Origin] Folder Containing Hi-Res CMYK camera-ready .tiff photos
- [Destination] Folder containing low-res RGB web .jpg photos
- [New File Preset] 350px wide x 375px tall; RGB; Adobe 1998; White background; 8bit
The current process that I use to get my camera ready files to web pics, is through an action that I have set up.
These steps play in my action (including new file preset, specs above):
-1. Hi-res file contains only 1 layer which contains a mask to cut the image from it's background;
-2. Selection is made from layer mask
-3. Layer is set to active retaining mask selection
-4. copy (image contained within selection is copied)
-5. paste into new file (preset above [New File preset])
From this point I manually size the photo to fit within the new file size preset by transforming the pasted layer and dragging (downsize) by the handles. After this I simply save file as a .jpg
This action is just fine for single files but will not work for batch processing because 99 percent of my hi-res files are much larger than 350x375 which will leave them pasted at actual size and cut off.
My first solution was to include a step in the action that would resize the image down to the size needed. The problem that I am now faced with is that when you include the transform command in an action, it just records the 'percent' value which has varying results.
To sum it up, I would like to batch process many images at once with an action that will take my destination images and manipulate them and store them in my target low-res folder. The final dimensions will be 350px wide x 375px tall which is rectangular. My files vary in size and proportion; some being tall rectangular, wide rectangular, and square. The initial dpi is 300 but when finished it will need to be 72.
I have experimented using the 'image resize' command but not getting a result that will work with all proportions of images.

how you would batch resize a ton of photos to 50 % of its original size.The workflow I've had before is going trough image processor and doing the resizing when I'm converting to .jpeg. The only problem with image processor is that the resizing doesn't seem to be smart enough to differenciate horizontal with vertical.
So say I choose a specific resolution of 2880 x 1920p all my horizontal pictures are great, but the vertical ones turn out at 1280 x 1920p.
So how do I batch resize in a way that photoshop would know to turn horizontal pictures to 2880 x 1920p and vertical ones to 1920 x 2880p?

I am using Photoshop CS3 Extended
I am familiar with batch jobs in Photoshop.
I have images that vary in pixel size and resolution.
This project is for an online gift registry. First, we are hosting the images, but they have restraints due their web/system programming. So what I was told by the company was they need the images to be 300 x 300 pixel images at 72dpi. They said they would settle for 300 width only and let me scale the proportions and not worry about the height as I want to batch the process. But they stressed 300 width and 72dpi.
What I have tried is batch resizing all of them to 300 pixel width, worked fine. Then I batched changing the resolution to 72. But it changed all the pixel dimensions to various sizes. So then I tried to batch 300 pixel width and 72 resolution at one time at it ends up the same way. So what do I need to do to get 300 x 300 pixel and 72dpi?
1)I have read plenty of PPI vs DPI. Is "resolution" in Photoshop, PPI?
2)Was what they probably meant by 72dpi actually 72ppi?
3)How do I accomplish this?

I have about 1000 images that need to all be resized to 5MB. All the images are in different color modes, have different resolutions and pixel sizes. Is there any way to make an action to resize image to 5MB? I don't care about pixel dimentions or resolutions, I just need all the images to be 5MB.
I'm running Photoshop CS 2 on Mac OS X 10.4

Is there a way to Batch-Resize photos?
I have 160+ photos of different sizes (but mostly 1600 x 1200). I'm running them in a loop for my screensaver. I transferred them to my cellphone, to be used as wallpaper, but they're too big to fit the screen. I can only see a portion of the image. So I'd like to reduce the size for them all, without having to do each one individually (and tediously).

there were a simple batch process for resizing ... primarily for resizing width. This would be good for quickly creating thumbnails from larger images.

I frequently use a script to resize .jpgs from 3600x3600 to 1000x1000 dpi to save space on my hard drive. After resizing 300+ .jpgs last night, I found that they all retained their original file size. An image that started out as 3600x3600 dpi with a file size such as 3.5mb that was resized to 1000x1000 dpi using the script in X4 still had a file size of 3.5mb when it should have been considerably smaller than 1mb. I relaunched the application and rebooted my computer but no change. To fix the problem I had to run the .jpgs thru the batch process again using the same script but in X3.
The script I was using was created in X3 so I tried creating an identical script in X4. Regardless of which script I used in the X4 batch process, the same thing happened.
This problem seems to be unique to the script and/or batch process. I can open a .jpg file in X4, resize it from 3600x3600 to 1000x1000 dpi, save the changes, and the file size changes accordingly.

Maya keeps resizing the height of an animation during a software batch render to 180px. Rendering a single scene, the size is as specified in the settings.
I've got an animation I need to render. I'm trying to render at 640x480. I can render single scenes or the entire batch in Hardware mode and it renders at 640x480 no problem. I can render a single scene in software mode and it renders at 640x480. If I try to batch render the animation in software mode, Maya resizes the height to 180. If I reset the size of the render to 1024x748 Maya once again resizes the height to 180.

I need to be able to re-size images that are large than 1MB in order to put them on our MLS site.
My previous computer had 2 arrow icons on the desktop.
One was for re-sizing horizontal pics and the other for re-sizing vertical pics.
I could simply drag/drop the image file onto these re-sizing icons and they would be re-sized.
The smaller file size thumbnail would appear on the desktop.
How can I get these re-sizing tools on my new computer's desktop?
I am using CS6.

This is something that i never really gave much thought - but what value do the opacity parentages really have?
See my assumption was that 50% + 50% = 100%. So if you had a solid black layer set to 50% opacity and you duplicated that layer one would think that it would be solid black again... but no is only 75% black. WHAT?
The other thing is that solid black with and opacity level of 50% over solid white is a true 50% gray which is half black and half white - do to half's not make a whole?

Who has experience with the "select"-tool?
In a picture I'd like to get the ratio of the selected and the unselected areas. That means: I select several parts of my picture (for example by using the magic wand tool) and would now like to know the portion of the selected areas (area of the selected parts, percentage, ....whatever) compared to the unselected ones.

Any way to set a default zoom percentage value in the Photoshop CS6 Navigator panel?I normally zoom in and out using the CMD and + - keys, which give 12.5%, 16.67%, 25%, 33.33%, etc.I would like to set the value at the bottom left of the Navigator panel to 31.5%, then click and somewhere and save this as one of the default settings, so that it would replace,33.33% or come between that and 25%
A bit of a strange value I know, but I've found that this value gives me an image on the screen that is the same size as what I get out of the printer.bind having to type in 31.5 over and over again in the Navigator.

I am trying to create "degraded" stimuli for an experiment - specifically, I'd like to remove a consistent percentage (70%) of pixels from an image and replace them with solid black. It is important that the pixels are removed in a random fashion - that is, if I modify a series of images in this way, I don't want the black areas to always appear in the same portions of the images.

I'm trying to define my own watermark (just a piece of text) and define it as an action so that I can apply it as batch.
I'm creating a text layer as the signature, and I would like to move this text layer to the lower right corner of every image. For this, I'm trying to find a move by percentage command that will work for any image size. i.e. the signature must appear at 90% of the width and %92 of the height, regardless if the image is 2592x1728 or 1728x2592 pixels.
How to do a 'move by percentage' or alternative ways to achieve this?

Just got CS6 and I cannot find the little percentage figure that used to sit at the bottom left corner to give an indication of the image size you are viewing and allow you to alter it. I'm sure it must be in there somewhere but I can't find it - and believe me I've looked.

I have a windows 7 based machine with 24gb of ram and a 560to geforce video card and 980x CPU. have just reinstalled Photoshop cs5 and newest update, Photoshop now opens images at a viewing percent that is a lot smaller than the previous installation, currently a vertical image is 16.7% and a horizontal 25%, these should be 25% and 33.3% to almost fill the screen. what can I do to get images to open at a bigger zoom percentage?

I just upgraded to CC from CS4. In CS4, when recording an action I could set the rulers to percent and a percentage-based value would be recorded rather than a pixel value. For example, if I recorded the creation of a vector shape that filled the entire canvas, the step in the action would create a 100% by 100% shape, starting at point 0%, 0%. This allowed me to run a batch on varying canvas sizes, and get a shape that filled the canvas no matter the size. In CC, it always records pixel-based values no matter what the rulers are set to.
