Photoshop :: Resolution Change - Reduce Image File Size?
Jul 13, 2013
What is the best way to reduce an image's file size (say by 50%) so that someone with limited RAM can work on the file and then when they are done restore the file back to its 100% size for final output--without sacrificing resolution or pixels. File is a layered psd and will eventually be going to print.

I have some really large blueprints (black and white). Some of them exceed 30000 x 8000 in size. I want to reduce the overall size of these but when I try this my image gets really fuzzy. Is there a way to make these images smaller without messing up the clarity?

see attached
the default setting is 1920 - far too low for me
ok it can be supressed on a session basis, but the number of clicks to acheive anything keeps creeping up and I'd rather not see it at all - AFAIK there is no way to suppress it permanently, but the default setting can be increased in the registry
I have my setting at 8000
the registry key is 'ImportSize' in Options > Filters [ verified in designer pro X]
changing registry settings is only for those who know what they are doing and who backup first

Is there a way in Photoshop to change the image size and resolution to a folder that has many jpegs images in it? Otherwise I will have to change the size and resolution to about 250 images. If Photoshop won't do it is there another program that will?

Currently the screen has a black border when I scroll to reduce the image size. Originally it may have been white.

I am trying to export PDFs of drawings with a high resolution image covering almost an entire A1. I realize of course that the file will be very large but it is much larger than I feel it should, and there are also some discrepancies.
The original image is around 100 MB, but only about half is visible in the viewport, so the PDF should be around 50 MB if there is no compression (only negligible amounts of text and lines besides the image), however if I plot it to a PDF using Adobe PDF, setting the resolution to 300 dpi and medium JPEG compression the resulting file is 150 MB. If I choose 72 dpi and low JPEG compression the file looks very bad and compressed but is still around 40 MB in size. This is far too large considering the amount of compression visible in the image, it looks like a 500 KB file tops.
However if I use the DWG to PDF printer instead of the Adobe PDF I can get a very good looking file at around 2,5 MB. Very suitable for printing, but the compression shows if you look up close in the computer (which is a requirement for these files). The odd thing here is that it makes no difference what resolution I set it to, 150 DPI to 1200 DPI creates the same looking file at exactly the same size. I'd like to be able to create a 2,5 MB file to email and a very high quality file for archivation, but not 150 MB large.
Another odd thing is that if I print another file but with the same type of image (a different facade) with 1200 DPI I get a very high quality file of 40 MB, but if I repeat the exact steps and settings for the first file I end up with a 150 MB file. Of course some differences in the image would account for some of this, but not nearly of this magnitude. I deleting everything from the large file and copying in the content from the small file, and successfully printed a 40 MB file again, so there doesn't seem to be some setting or bug in the file I am printing from, rather something in the original file with the image that I have Xref'ed.
How I would go about creating a very high quality file that doesn't bloat up way more than the original image? A 40 MB file is great considering the images are huge, but I can't get this result consistently.

I have load of files that I need to clean up to reduce file size (mb) without reducing image size. I have manually been doing this in tree steps; merging active layers and deleting hidden layers, deleting unused channel/masks and deleting all paths. For the layers part I have managed to create an action and run it on multiple files through the file>automate>batch menu, I would like to the same for the channel and paths or possibly all three in one.

I just got back from a trip where I took about 1,400 pics (Nikon D300) each of which is about 2.4mb. How can I save them in bulk to a smaller file size? I need to send them unedited to my Daughter so she can look them over and tell me which ones she wants.

Can someone please explain to me about file sizes and image dimensions. I have to put together a collage which is 165mm high by 258mm wide. If I click file new and choose default resolution (72) then the file size is ok, if I type in 300 dpi the image becomes huge.
If i chosse 300 dpi then the images I was going to use seem tiny on such a vast workspace - Im confused why does the canvas become so large when changing resolution?

I was given an image with these dimensions:Â
w: 13.89Â x h: 5.56 inches.
I'm being asked to make it fit these dimensions:Â
w: 8.5 x h: 5.47 inchesÂ
Â
How to achieve this without the picture looking stretched, in terms of it's height. Everything looks constrained when you just do the image or canvas resize.

I am preparing images for the web and I really have 2 questions: one about gifs, and one about jpgs.My standard procedure is to reduce the image to the desired pixel dimensions at 600 dpiThat gives me a crisp small image. then I either use it as is if the file size is low enough (I try for under 600 kb) or convert it to a gif with the save for web and devices tool.
Â
So here are my 2 questions (I will count this solved with either answer)
Â
1) When I convert to a gif I have the 4 boxes: one with original size, the other 3 with options but often the options are too low res for me How do I change my 3 options to start at a higher gif res?
Â
2) If I try to reduce the file size of the jpg in the image size box I set the resolution lower ( 400, 300), which lowers the pixel dimensions and the filesize, but I don't want to cahnge the pixel dimensions. And If I reset the pixel dimensions back to the size I want them, even though it is a lower resolution the file size doesn't change.
How to reduce jpg file size using only the resolution, not pixel dimensions? PS I have tried messing with checking and unchecking the 3 little boxes( scale styles, constrain proportions, and resample) but nothing has worked.

So I am familiar with how to use Photoshop actions and how to batch process, but right now I am on a project where I need to batch process a large number of employee photo headshot images to be 100x75 pixels AND must be between 12 kb and 20 kb.
So the 100x75 pixels is easy, but my questions are this.
1. How can i have an action save the image image in that range for the file size ?
2. is there a way that I can have the action pause so I can center the person's head in the photo when cropping?

I have a task I need to perform often. I create charts that have descriptive texts below bars. There are two lines of text... a company name, then data on the second line. The text is at a slant, so each bar has its own separate text (i.e., I can't create it as one continues piece of text... but the text below each bar —the two lines— are connected). I want the first line of text to be 8 points and 100% black. The second line of text is to be 7 points and 50% black. So let's say the text is 8 pt Arial. I highlight the second line and run the action on it to reduce it down to 7 points. No problem. Then I run a second action (ideally, I'd like to combine actions, but I can't as you'll see in a moment...) which turns that second line to 50% black. BUT... it turns BOTH lines to gray... not just the line I have highlighted. How can I stop it from doing this? It seems like if I have only certain text highlighted, it should only apply changes to that particulat text! Not ALL of it.
Â
I'd like to combine both actions so that all I have to do is highlight the second line and run both actions. But I can't do that at the moment
Â
I'll attach some photos that will hopefully make this make more sense.
Â
I'm using CS6 on a Mac. The charts are initially generated online, if that makes a difference.

I have an image that I took in RAW with a Canon 5D. I then masked a large portion of the image using the adjustments brush. The result was what I wanted but the image is now very large. I exported the image to a DNG to retain editability. The resulting DNG is 53,679 kb. If I export the image to a JPG at 25% quality limiting the size to 2000 pixels on the longest edge I still get a 7,795 kb image.
Â
I have had this problem with masking before. Is there any way to get rid of the bloat that the masking caused?

I have an ai file. It is exported from PRo-E, so there are lot of nodes in that ai file which makes the file size larger. Is there any way to simplify the ai file without disturbing the profile of the entities in ai file. I tried Simplify options. It worked a little bit. But i want any other option to simplify the ai file in order to reduce the file size in a larger extent.

Many of our AI-files have a tendency to 'bloat' to sizes above 60 or 100 MB, even though they relatively simple, all things considered.
Â
The obvious answer would be to save with PDF-compability, but since we need to link the AI-files in InDesign-documents, that's not an option. We have cleaned the brushes, the symbols etc. and all pictures are linked, not embedded.
Â
Are there any other ways to reduce the file-size?
