I'm trying to make an avatar for the forums here, but I can't seem to make it small enough (file size) for it to be usable.
Is there some way I can compress this down to 8kb without losing quality?
I have many images of slides scanned at high res (4800 DPI, maximum pixels 5214x3592).  Although I will be saving these as loss less TIFs, I also wish to make JPGs from them that I wish to be just less than 5 MB in file size. Aside from cropping, I know I can achieve such a reduction of JPG file size by a combination of saving to lower quality JPG compression or reducing image size. My question is, what is theoretically or practically better, achieving this mostly by reducing image total pixels or by reducing JPG compression quality.Â

I've got a JPEG image file straight from my camera that's approximately 4.1MB in size. If I do nothing else but "Save As" with a compression factor of 1, the new file size is approximately 50% larger, or 6.2MB. What has changed to make the file size larger? Both images are still 72DPI, 3648X2736px. I can't image that I have done anything to "improve" image quality, so why did the file size increase?
View 14 Replies View RelatedI have completed a project and I need to verify that, based on what I implemented, image should be resized but quality of image (both JPEG and GIF) should not be reduced.
My question is it possible to verify the result using photoshop or some other tools? How?
My college said it is hard to check if an image looks different because of image resizing or because of quality loss or because of both. He said I have to create some log files to trace the result. It is a little too much work for me.
I've got a file of about 40mb which saves as a max quality jpeg in Photoshop at around 12mb. Once it goes into InDesign and comes out of the other end as part of a PDF the file size is down to 3mb.
Â
I'm convinced data is being lost but one of the answers seems to indicate that zip compression is now being used in addition to the jpeg.
Â
I always thought it was hardly worth zip compressing files like jpg, mp3 etc that are already compressed and that the only way InDesign could be knocking my jpegs down to a fraction of their size was by recompressing them as lower-quality jpegs?
 When I save a file to jpeg the image size in photoshop remains the same as it was as a tiff file BUT according to the information that comes up in windows properties the file is much smaller (300k vs 2.9mg).  Can you advise me which is the correct file size?  If the correct size is the one showing in windows (300K) does mean that the file compressed in JPG and lost a lot of information?
 and if this is the case how can I prevent that from happening and still save the file as a JPG?  [ I would like the image to remain the size photoshop shows it to be] . Thank you very much.
what is the diffrence between these two pictures(the same picture both are .JPG images but the quality and size is diffrent)
i assume that they are saved with diffrent compression and encoding or sumthing like that.
BMW 1 (Good Quality)
BMW 2 (Normal Quality)
Cadalac 1 (Good Quality)
Cadalac 2 (Normal Quality)
EDIT: to see the diffrence between them, you must look at them with atleast 2x or 3x
I have CS3 extended and have been compiling a series of high resolution photographs into one layer in photoshop. I have copy and pasted each photo and then stitched them together resulting in a file that is 1.35Gb. I want to compress the file, keeping the resolution as high as possible, so it is easier to use in illustrator and import into ArcGIS. I have tried saving the file as a jpg, pdf and tiff with variable compression qualities. As soon as i open the image up in a different programme and zoom in I loose the picture, eitehr to a blank screen or a message saying 'invalid format/picture'. Opening the file and saving is taking so long too do as well...

We got several image files every 2 weeks which should be edited and mainly reduced in size for web purpose. This work needs 1 work day for one man/woman to do, because he/she has to open the file save for web and then set the quality to a value were the file is nearly about 150-200 KB in size.
Â
The images are different, some have few colors, some have a lot of colors and there are also different in resolution. But they should not be reduced in resolution, only in quality. All other specs of the image should be keptÂ

Is there any possible script, plug-in or similar which can do the same (Saving with a specific max. file size) in some automatic and faster way?
After working on a jpg file, when I want to save it, still as jpg, with my Photoshop CS5,
- sometimes photoshop will just save the picture, and it's done
- sometimes photoshop will show me the compression dialog, "JPEG Options", in which I can choose the compression ratio, the format options (baseline, baseline optimized, progressive), and have an estimation of the total file size
Â
While not being prompted any dialog is simpler, and I'll then simply assume Photoshop decides to retain the current image's compression and format rules, I must say I like to be in control, and I'd like to know under what form the file is being saved without having to resort to the much more complex "Save For Web" menu.
Â
WHAT "triggers" the appearance of the JPEG Options when we close/save a jpeg file, in photoshop ? What makes this menu not to appear, what makes it appear ? If there are trivial file operations/changes/filters that necessarily trigger its appearance when we want to save, something like that ?
I use CS5 on Win 7 64-bit. Today I learned about this option to disable file compression to speed up save time:

Â
I downloaded the reg key and installed it. When I restarted PS to test it on a file, there was no difference in either save time or file size. The test file is a 300 MB multi-layered PSD file.
I'm trying to add audio to a slide show. I've done it before on this computer with no problem, but now it's telling me I don't have the correct compression files installed on my computer.Â
View 1 Replies View RelatedWhen creating a Photoshop file I understand how to calculate the document size, ie, No of Pixels / Resolution. I also understand that the formula to calculate the number of pixels in a file is size in inches x dpi.
What I'm not sure about is how the number for pixel dimensions which can be viewed at the top of the Image Size window in Photoshop is calculated. For instance if I create a file that is 1500 pixels wide x 900 pixels in height with a resolution of 300 ppi it gives a pixel dimension (file size??)reading of 3.86M.
I had always assumed this was the actual file size! However when I right-click on the file and see the file size it is much smaller.
I see how to resize images by change the pixels or dimensions but is there a way to limit the file size? For example, when submitting images for review some organizations set a limit on the size of the file, i.e, files may be now larger than 5MB. Other than byt trial and error is there a way to set a file size limit?

When converting the colour of a Jpeg to CMYK in Photoshop CS5 the file size is increasing.
Â
The original image is 352KB and after saving as CMYK it is 2.1MB
Â
Why is this happening and how can I stop it?
Â
I'm using a lot of images for a print project so need to keep file sizes small with resolution of 300dpi. The image dimensions are really small, only about 30mm high so they shouldn't be this large a file size
Â
I am using a clipping path but this doesn't seem to be effecting file size (I checked by saving it as RGB with a clipping path which stayed small, and by saving one without a clipping path in CMYK which was huge)
I am using Photoshop CS5 with all current updates installed on a Mac running Lion. I am having a problem with the handling of the camera raw format (specifically .arw) and how Photoshop handles the format.
Â
My first issue is that upon loading the format into Photoshop, the program is cropping a bit of the image from both the left and the right. I have not found a way to stop this from happening.Â
Â
Another issue is file size. A client is having issue with the file size presented. They are providing me an ARW file that is 14.8 MB and I am making edits and provided them with a large jpg from photoshop (jpg qaulity turned all the way up) and they are getting a jpg at 9.7 MB. They are concerned that I am giving them a less than quality result.
I know that any conversion from a camera raw format to a high resolution jpg will result in a lower file size and that has been explained however the client has taken the raw format parsed it through Mac Preview, saved it, and resulted in a larger file size than I could provide in Photoshop.Â
Â
This then becomes a confusing situation to handle.
Â
Questions:
a) How to explain the lower file size happening in Photoshop to the client (what is lost?)
b) Why they can use mac preview and get a larger file size that I can at full resolution jpg in Photoshop?
c) Is there a way I can make this client happy without moving to a tif file format?
d. Why is Photoshop cropping the .arw file?
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.
View 3 Replies View RelatedI've created an image file in Illustrator and exported it as a .png file. The dimensions are 1000x200 but when I export it the file size changes and becomes bigger. I therefore have to change the file size in Fireworks making sure that the quality is kept as Photoshop does not do it for me. Previously when I exported the files the backgrounds appeared transparent after saving but maybe I've changed a setting by accident that has changed this.
