Photoshop :: Reducing File Size & Retain Sharpness
Mar 24, 2003
I am using photoshop 7, I am trying to reduce jpg images around 1 mb sized at about 2400 x 1800. I am trying to reduce the image down to about 5 centimeters and retain the sharpness.
I have found that my images are blurring a fair bit.

I have a background that has 8.5" x 11" external dimensions. In the project bin, I'm also showing a layer (with transparent edges) that I've resized to 1" x 1.5". When I double-click the background to put it on the screen, and then drag the layer onto the screen, why doesn't it look like a small picture on top of a big one? Instead, it's huge, and I have to drag it down to size with the move tool!
And now, the entire story:
Running PSE9 under Mac OS X 10.6.8 Snow Leopard.
My project is a montage of stamp-sized images on a letter-size background, as in the attached -- commemorating the woman in the centerpiece. I've stumbled though this kind of effort before with great success. This time the small photos are coming out blurry, and it's because this time I've done one thing differently.
In prior efforts, I recall somehow reducing the outside dimensions of an open file to about 2" x 3" before editing and finally adding it as a layer to the big background (using Move Tool to size it to fit), although during editing I was working with a reasonably-sized image and not a stamp (probably using command +). The images in the final version were all sharp. On this effort, however, cannot remember how to do it the same way, and I ended up working with the original photo, and then when I added it as a layer, I reduced it using the move tool -- very clumsy in view of the fact that the edited layer's image seemed to be larger than the canvas I was building, and the final images were blurry.

how I can retain sharpness while enlarging a graphic. I'm doubling the size of a graphic and it's getting really fuzzy. I tried the sharpen filters, but they just make it more boxy.

I need to use a couple of screen shots in an e-learning course. The screen shots contain text and when I try to reduce the sizes of these images the text becomes fuzzy. I've just worked out how to reduce an image size in Photoshop.
(I'm not the most proficient user; I bumble through processes when I need it.) I've used 'bicubic' and 'bicubic sharper' in the reduction process, but both produce a fuzzy appearance. Is there a way that I can reduce these images while retaining as much textual clarity as possible? images have not been created in Photoshop. And I'm not sure if it makes a difference, but I'm using SnagIt for my screen grabs.

Working in Adobe Photoshop CS. I have a tif file that is 36"x36" at 150dpi.
Flattened image; Grayscale mode. File size is 28.499MB. Is there any way
to reduce the file size other than change it to a jpeg? I need to email it
somewhere and they can't accept files over 20MB.

I had a question on reducing the image size after editing in Photoshop.
After doing my changes in Lightroom, I typically make edits in Photoshop and then do some final touchups back in Lightroom. The RAW file from my camera is approximately 24 MB. After making my edits in PS, the TIFF file it produces (with all layers flattened) is in the 60 MB range.
My question is, if before sending in back to LR, I change the image size in PS say to 12 MB or so, am I basically creating a lossy jpg file? Meaning -- by reducing that TIFF file size down to 12 MB am I throwing out important information such that when I go back to LR I am losing information and won't have as much control as the 60MB TIFF file?
keep upwards of 80MB per image (due to the RAW + edited file). I don't want to lose imporant information so I will if I have to, but would prefer not.

I designed artwork for a large banner (84" x 32") so my AI artboard is that large. As you can imagine, with all the text and graphics I used, this file size is 22.8 MB. I need to email this art to the printer, but the file size is too large to email. How do i go about reducing the file size in AI so it still maintains large format print resolution? Will saving to a PDF lose the print quality?

I made a 8GB video in PAL sometime ago. Some of my relatives in Canada cannot view it. As I do not have the original footage, I imported the DVD into X3 and tried to create a DVD in NTSC format. The final size came to 9.3 GB and it appears X3 will not burn or create VIDEO_TS folders if the size is more than 9GB. I was hoping I could use DVDShrink to reduce the file size to fit a 8GB disc once the VIDEO_TS folder is created on the computer.

I have a 3D model that consists of a large number of "small" objects that i created earlier in separate files. The problem is that now my model is 50Mb and I am having trouble working with it. Is there a way of reducing size, or is there any other solution that would not change the geometry of my model?
Working with Intel Quad Core, 6Gb of ram and ATI Radeon HD3800.

I have a number of files which were prepared in Corel Draw which I would like to post online. The designer has supplied the PDF versions of these files, however, the files sizes are too large for web usage. A 8 pg document is 5Mb. I have tried reducing the sizes by compressing in Acrobat; importing the PDFs into Corel Draw and re-creating PDF files with reduced resolution; recreating the PDF without the bitmap images (there are about 10 images)..yet the file size of the PDF does not change significantly.
What else can I do to reduce the file size of the generated PDF files? The files are newsletters, so most of the content is text and a few shapes and lines.

I am having a problem when exporting surface data into an .xml format using AutoCAD Civil 3D 2012. I am using LIDAR information to create a surface over an area of approximately 3 hectares in order to undertake future flood modelling. When I have created my surface in Civil 3D the overall file size is around 5MB, however when the surface exported to a .xml format the file is approximately 860MB. I have tried to create a new surface from contour information to decrease overall fle size but with no avail. Any recommendations to decrease the .xml file size without having excessive loss of accuracy for my modelling.
Lidar information that I am using to create surface can be found at URL.....

My intention was to convert a 3DS-File into an IPN-File, to use it in Inventor.As I did not managed to do this in Inventor, I importet the 3DS-File in CATIA V5 and converted it into a CATIA-CatPart and from there in an IGES.Then I was able to open it in Inventor and made a IPN out of it.
The PROBLEM: The original 3DS-File had 700 kilobyte but the actual IPN 54 MegaByte !

We were sent some step files of valves from a company - what would be the best practice to make this into (clean up) a useful part to be used in our assemblies. Interested in converting it into a useful part but reduced in size. (Compared to other valves we use - this is easily 10 times the size).

I have two designs for labels that have to be approved by the government for type size regulations. The current size of the illustrator files are 133.3 MB and 24.7 MB I need to provide these at no larger than 450 kb AND the type must be readable and measurable for approval.
I have tried everything I can think of to provide the artwork small enough yet still retaining enough resolution to not make the type fuzzy and not able to be measured for size. I've tried making the files from within illustrator, I've tried taking everything into Photoshop to make the JPEGS with no luck. They want either a gif, jpeg or tiff no larger than 450 kb that is viewable at the print size of the label with no loss of resolution...

In vX1 I could save jpeg without substantially reducing file Mb size. In vX4, whenever I edit and save a jpeg file (using save & save as), it results in a reduced number of Mb's. Options in the 'save as' dialog are set at best. It would appear that PSP X4 is automatically optimising. Is there any way that the original file size can be retained on saving after editing?

I need a picture resized (larger). But it is a very small picture and when I resize it, off course, it is not worth looking at anymore... I did capture some of the talking on vector based and pixel based, but how do I adjust the pic so I can resize it?

I have a large image at 72 ppi. When I reduce the size (pixel count) leaving the resolution at 72 ppi, the smaller image loses sharpness. Why is this happening?

I have several 35mm images scanned at 8000ppi and are typically around 450Mb (a few are 500+).
The Problem - to get these onto 1 or more of the various sites on the net I need to reduce the filesize (i.e. the Mb count) (e.g. 1 site has limits around the 30Mb mark) B U T ALSO RETAIN the PIXEL count in order to produce the best possible print.
While I can save as a JPEG at something less than 100%, which does this, I am not all that keen in potentially losing some quality.

I have a cybershot and have it set to 1280 x 960...Fine. The pictures look great but sometimes when I upload to walmart or shutterfly them become pixelated. Or when I use irfanview (PC only program) to resize to something smaller and pixelates them as well.
Should I change the camera settings, if so, to what? Should I use PS to resize them?

I have these PDF catalogs which are about 20 - 50MB each. Some of my customers are not comfortable browsing online so a digital catalog (here) works better for them... The same people generally have bad internet connections so I need to re size these PDF's so they can be downloaded rather quickly.
Starting with a 20MB PDF, I open all slides within Photoshop. I batch process the images from 300dpi to 96dpi , and shrink the size from 24 Inches across to 15... All the images are saved in a new folder, opened back in Photoshop and a new PDF is created. Considering both size and dpi has been clipped by a fairly large amount, you would think that the new PDF would be smaller... But its not, the 20MB version ends up around 60MB afterward.
I don't feel like purchasing Acrobat Pro because I know this should work within Photoshop.

I have designed a billboard and used various photos. Due to changes in the positions of the layers, I ended up with a canvas bigger than the photo. So I need to remove the extra canvas. How do I remove the extra canvas?
I can use the marque tool to copy/cut and paste the photo unto a new file, and hence get rid of the extra canvas. If this is the way forward, is there a precise way to get the marquee tool to the edges of the photo? Is there a function to snap the marquee to the edge of the photo?

I have 900 photos/ scans that are all large in size. I know want to make them suitable for a web site ie 72/91dpi and around 1024*768 px in size . thought the save for web choice via an action was the way to go ie create the action and then run as a batch.

I have been told that you can reduce the number of pixels in a picture, but keep the size of it.I am unsure about this, so I thought I would ask the experts as it were.I do know the JPEG image compression when saving, but is there any way you can specify the number of pixels?

I have a Sony camera and have it set to take big pictures with high reso.
In PS, can I reduce the size 3 MB to something a lot smaller but still keep ok quality? I go to Image Size but that just makes the pic smaller (duh) I want to change the actual file size.

wanted to put all my holiday photos on a picture-sharing site (Photobucket), but it seemed they were too big and it took forever. It was suggested that I reduce their size on Adobe Photoshop and I have downloaded it (Starter Edition 3.2). However, I can't seem to find a facility to do this. What I would really like to do is reduce all of the file sizes at once. Is this possible? Otherwise I will reduce them one by one, but don't know how to do this either.

I read somewhere that in Photoshop you should reduce images in steps, but never in one big step. For example, if you had an original 3200 pixels wide, you should first reduce it to 3100 pixels wide, then 3000, then 2900, and so on, down to about 2000; then, if your target is 800 pixels, you may increase the interval.
Does this rule of thumb still hold true in CS4? I've tried one-step reductions, and these tired old eyes could not tell the difference ...
