Photoshop :: Save For Web Vs Resizing Vs File Size Vs PNG
Mar 14, 2012
In playing around with some settings while saving a .png file, I noticed some weird results. For this example, the original image is 300 x 300, but I want the final size to be 200 x 200. I get different results depending on the order I perform the following operations (I never thought the order mattered until now).
1. start with 300 x 300 image, choose save for web, select png-24, with transparency, white matte, convert to sRGB, change image size to 200 x 200, then save - the file size is 37kb.
2. start with 300 x 300 image, use Photoshop's "image size" to change to 200 x 200, then save for web, etc - the file size is 111kb
So depending on which step I resize the image, the file size is significantly different - if I resize BEFORE using save for web, the file size is much larger. This is just weird to me, but I always resize AFTER choosing save for web, so that's why I've never caught this until now. In case you ask, while using Photoshop's "image size", all three options are checked at the bottom of that window, so nothing is getting re-sampled or anything like that.
The only thing I can think of is each of those methods treat pixel data differently when reducing the dimensions. When I overlay both exported .png files on top of each other, I see no difference in pixel quality and/or color shift - so why the big difference in file size? if I just save the file straight to .png, the sharpness is much better, and the file size is 46 kb. I did notice when saving for web, the colors become a little more saturated.I've never really paid much attention to the results when exporting .png's.
1) How do i deal with digital photos from a camera? I mean, if i have a 1280x960 300dpi 3.5MB photo , how do i resize this into a smaller photo to be uploaded to a website? Should i change the resolution to 72dpi? which makes it 307x230 with a file size of 207 kb. But how come when i tried to change the pixel dimentions to 307x230 (leaving it at 300dpi) the file size was the same at 207kb? how should i really resize photos? how do i deal with the resolution, pixel dimensions and document size?
2) In saving graphics to be uploaded to a website, whether a resized digital photo or an original artwork, what format do i use? Jpeg? Gif? Png? I normally use Jpeg but what confuses me is the jpeg options, whats should i use Baseline Standard or Baseline Optimized? Another thing, how high should the quality be, im afraid to set the quality to high because it might take time to view on the webpage but i also dont want to sacrifice the quality.
way to specify a certain MB to hit when resizing images using an action?
The reason I ask is that I work with TIFF files that generally start at 60-100MB which I then have to resize to be around 25MB - and I'd like to build this into an action that I can repeat on all images.
At the moment, I'm doing a little guess work when creating an action that employs the Fit Image function. If the image height:width is close to that of A4, I find setting the fit image option to around 3300x3300 pixels usually works. However, a lot of images that I process don't fit to such proportions, which is why I'd much rather be able to set 25 MB as the target size instead, if this is possible...
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 have Photoshop CS6 and Elements Premiere 11 and both were showing estimated file sizes properly up until a couple of weeks ago, and both stopped at the same time. Using Image, Mode I have verified on both that the images I am trying to save are 8 bit and not 16 bit images. I am on Window 7, 64bit.
I'll come straight out and admit: yes, my real problem here is my laziness but, ignoring that, the 'problem' I have is getting so tired of and annoyed with the whole trial & error schtick that comes with saving animated gifs (scale image, save, check file size, repeat to first step until file size is finally desirable).
Two possible solutions come to mind, one I admit is probably quite unrealistic but I would think the other has a good chance of existing.
First, the unrealistic solution possibility. Is there a plugin or anything else where I can input a file size and it could calculate the exact (or close to exact) scale I would need to resize to if I want the gif to be around that file size? (i.e. "For this gif to be 879kb your best bet would (probably) be 515 x 283")
Now then, the more realistic (or at least I think it is) solution possibility. What about being able to preview a file size of an animated gif before saving? (i.e. "If you save this 400 x 226 gif it will most likely be '(insert byte size here)'kb")
am having an Issue with CS6 when saving files. When saving a file using the 'Save' option (not 'Save As') the file is not staying at the size of the artboard as it should, it is however being aurtomatically cropped down to the actual artwork size. This is causing issues with the Process we work with as we need the file to stay at the artboard size.If I click 'Save As' and change the Adobe PDF Preset to 'Press Quality' then this works, however this means that every file we save(which is quite alot in a day) means we have to go through the 'Save As' option and manually change each save.why this has suddenly started to happen with our Illustrators and do you know how to fix this so that it stays at the Artboard size when 'Save' is used?
I am trying to optimize some images for web to have a smaller file size. I am using "Save for Web" feature, and every time I try to save a file, the actual file output size is a lot bigger than the size it shows on the "Save for Web" dialog.
For example, I have a 607 bytes .gif, when I open "Save for Web" it shows 207 bytes for 16-colors but when I save it the output file is 1.22 kb.
Is there a way, when saving jpg files to save as a specific file size, rather than quality level (currently using CS5)? I have a few clients (realtors) who require files to be 100kb (or smaller... but 100kb is the ideal to shoot for) for their listings.
Given I'm working with a number of images, I would like to be able to do this as a batch, rather than one at a time, getting as close to 100 as I can without going over, as I have to at this point.
when using the Save for Web... feature there is a place on the Quality slider where one point makes a disproportionately large jump in file size. It seems to me it is always at 50-51 but I'm not positive of that. Here are some results from a Save for Web...
47 = 226.7K
48 = 230.1K
49 = 236.2K
50 = 239.8K 51 = 298.2
52 = 300.5
etc.
I wonder why that sharp jump exists when files grow fairly proportionately above and below that 'break point." Needless to say I always keep an eye out for that issue when saving for web.
I realise there are pros and cons to this question and the temptation is to opt for the highest quality, but the file sizes are huge. So, my camera files will be mainly 1080 files at 30fps, what will be the best file type/size to save files for future use. I don't really mind the rendering time and space isn't a huge problem, but the variety of file types is bewildering. Most clips will find their way to DVD but I don't want to reduce resolution as they might be used at a later date for Blu-Ray.
I am using AutoCAD Civil 3D 2009.I have a project files suddenly file size becomes @ 10 MB after saving. Even Titlblock size is 7 MB.
I had installed a latest update over my system as well i tried to clean a file as per below thread. URL....After doing this file size reduced to KB. But if open it again and saved the file size go to MB.
The issue that I'm having really resides in AutoCAD 2012 after the file has been opened and saved in Civil 3D 2012.
For example, I can use AutoCAD to open a new or existing drawing that has never been used in Civil 3D. I'll run two audits, purge all twice, purge regapps, reset the scale list, then save the drawing. If I open it in AutoCAD again, the file size remains the same.
If I open it in Civil 3D, the file size increases that one time, which is fine. No matter how many times I open it and run the above commands, the file size doesn't change any more than 1 Kb while in Civil 3D.
BUT if I were then to open that same drawing in AutoCAD after closing it out of Civil 3D, then save - it will increase the file size by almost 100 Kb. No matter how much I run the previously mentioned commands the file size will not decrease in size. Additionally, every time I open that particular drawing in AutoCAD again and save it, it increases by another 100Kb+/-. These files are not very large, but I have wblocked some out to save more than 10 times the space.
I've seen similar posts, but they were regarding older versions and seem to be a little different than the problem we are experiencing.
I'm currently in the process of organizing my music collection with album art. I found a great site with high quality images[URL] .... and would like to resize pictures to 600x600 within the range of 200-300KB. Is there a way to automatically do this without changing the quality percentage by trial and error?
I have videos from my camera at 1440x1080, and after I edit them on Videostudio x4, when I save them (using MPEG4HD or AVCHD for example), the resulting file size is larger than the original. So I decided to use an encoder such as Xvid for reducing the file size. I choose avi as the output format and then in the options I set the resolution to 1440x1080 (not listed in the standard combobox, btw) and choose Xvid as the encoder (also tried ffdshow). But the resulting video is a smaller picture with a big black border instead.
I have an image received from a client in .eps format. I need to get it into either a .gif or .jpg format AND the final file MUST be .8 inches x .3 inces, AND no more than 10K in size. How can I save it with these dimensions/constraints and not lose resolution? What I have tried - export to .jpg (file is 5 inches x 3 inches), export and change resolution to 100ppi (image is nearly the right dimensions, but blurry). The tools I have are AI and PS both version CS5
I am having a problem resizing my images. I'm trying to make them wallpaper size or bigger. Everytime that I use the move/resize tool it distorts the picture, and makes it very very pixelated. How can I resize a small image to wallpaper size?
A .cmx file produced by CorelDRAW x5 can be opened / imported / edited in any previous version of CorelDRAW? Why size changes? When I export to .cmx size doubles. If I use the option "Save as ... cmx" the file size decreases. What´s the difference? URL.....
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?
If I open a .psd file with an alpha channel and resize it via Image Size to a smaller version and then save it again, the alpha channel is no longer detected in the new .psd file. I've tried deleting the alpha channel and re-creating it but it just doesn't seem to get recognized as having alpha transparency when I open it in other software (e.g., Preview on OS X). (note: I'm using CS5). It's specifically only happening through a resize using Image Size and not via Canvas Size.
I am a molecular biologist trying to use either photoshop or illustrator to label data (I have both programs, 1 may be better than the other for what I need, but I am not sure). The data I want to label are essentially pictures, of varying size, with a resolution of 50pixel/cm (around 127ppi).
The best analogy of the transformations of my data would be a picture of some random object taken next to a ruler. I need to label the ruler, then remove the actual ruler and just leave the labels. I have several of these pictures, and I label them like this individually.
I have a problem on resize images. How to resize the images from 72dpi to 300dpi without changing the image size in Photoshop CC? It enlarges the images or pixels, but i just want the pixel to stay the same.
shortcut that i can not use since two days. To redim the brush size it is possible to use the shortcut ALT + right click. This is very useful when doing painting or drawing on Photoshop. The problem is that i no longer have the possibility to use this shortcut, and i do not know why. My keyboard is correctly set up and i even reset Photoshop, but still nothing.
I have a PSD file (16bits/prophoto RGB) with some layers. I combine the layers to ONE and change the bit depth to 8 bits. Then I do one of two things:
(a) I save the file for the web in JPEG 90% high-quality and with sRGB ... filesize 340 602 (b) I change the color profile to sRGB and save the file as JPEG in the highest quality (10) ... filesize 174 549
I am at loss here. How on earth is it possible that the second file is almost half the size as the one saved for the web?What effect causes this? It is very easy to save for yhe web but as long as the JPEGs are that bigger it's no option.
how to auto fit overset text in a fixed text frame?
I import many languages into fixed text frames and it is a pain to keep resizing or scaling manually.
As of yet I've been unable to source any javascript or applescript that can do it. The closest has been "JET_AutoFitVertical.jsx" but this resizes the text frames.
is there a function in photoshop cs3 that will reduce the file size of a photo without affecting the physical size of it, i know macromedia fireworks can but thats no help to me unfortunately...
URL....I am using PSE 12 as a photo editor for Aperture 3.5.1 and the photo is duplicated (as a tiff) in Aperture and PSE editor opens with the image. When I close the file and say to save the file it brings up the save as window.
I tell PSE 12 to "on first save -- save over current file" it now brings up the "save as" window and won't save over the file (changes the file type from .tiff to .tif)
