The image exceeds the size Save for Web & Devices was designed for

I just upgraded from CS3 to CS5. I assumed that Save for Web & Devices would have been redesigned so that it would not complain with modern large photos that they were just too big!

However, it still does. I just don't get this. Photoshop in general now is editing very large images. It should be able to handle them also in this feature.

Is this just a legacy message, or is it really true that this feature can only handle small images?

    Correct answer

    Save for web was originally designed to optimize web graphics by squeezing out bytes while retaining quality.  It was not meant to scale and then optimize large images. This is demonstrated in the alert message.

    You could submit a feature request to Adobe to alter the original intent of SFW.

    SFW may display 4 versions of an image in various types of optimization. This requires saving 4 temporary files. Imagine trying to save a huge image 4 times at once through 'File-Save As'. This is why you see that alert message. It takes time to generate those temp files, especially when you throw a huge file at it.

    Consider a scripted solution to this where a copy of your image is first reduced, then transferred to SFW.

    Our original full sphere panorama images are 6000 x 3000px 16bit 105mb .TIF's.

    Photoshop CS4  works

    We converted them to 6000 x 3000px  8bit  .tif.  When using Save for Web and Devices we would get the "Warning 'Image exceeds".  We clicked "yes" knowing that it would take some time.... but that was ok.  The two pane panel properly dispalyed our 2 images. Original pane shows 7.5mb.  By using the compression slider we are able to get the file down to our desired file size of 6.5mb. 

    Photoshop CS5 does not work

    We converted them to 6000 x 3000px  8bit  .tif.  When using Save for Web and Devices we would get the "Warning 'Image exceeds".  We clicked "yes" knowing that it would take some time.... but that was ok.  The two pane panel is displayed now in RED overlay and fails to let us go any farther.

    Obviously, programmers really do know the maximum file size that can be handled in Save for Web.  Question is why isn't the maximum file size shown in the documentation... then there would no SFW issue to talk about here in the forum.

    Guess that is why I am still using CS4 for conversions  and later using CS5.5 for our normal work flow.

    CS4 and CS5 are two different programs. CS4 is based on Carbon and CS5 is Cocoa. You may be experiencing a bug that crept in through this transition. You can report the bug here.

    SFW's image formats (GIF/PNG/JPG) may have their own unique size limitations so the initial warning you see before SFW loads would not be able to know your intent yet. This is why a general warning appears.

    If SFW was actually used on images intended for web and device display (as it was intended) then there would be no SFW issue to talk about here in the forum.

    Thank you for your reply.

    Sorry I forgot to mention,  we are on a PC Windows Vista.

    So I know CS 4 SFW works and CS 5 SFW does not work.   Our output is to .jpg only.

    any update on this?

    I don't care about the intent of the warning, or the best time to resize, sharpen.

    I just don't want to have to see the warning again, ever.

    Any way to get rid of it?

    Thanks, Sheldon.

    As this thread started with a user's experience with a newly released CS5, you would need to install any CS5 update that has been issued since then.

    Supposing that you do not see any change after applying all relevant updates, you should probably try the easy workarounds suggested previously.

    thanks for your response Marian.

    I am running the the most up-to-date CS5, but this warning has been there for years (in older CS versions).

    I skimmed the thread, but I don't see any easy workarounds. Can you point me in the right direction?

    Save For Web is not intended to resize images, just to take the appropriately sized image and optimize if for the web (reduce number of colors, reduce quality, strip metadata, etc.).

    The warning is there for a reason, and it is a valid and true warning.

    Thanks for the clarification, Chris. I did a search of Help to see if I could find where Adobe told us this about this menu command, and found nothing useful. Where is this menu command (its purpose, and limitations) explained?

    Perhaps then you can explain the best way to take a fully edited, cropped, photo, very large, and resize it prior to applying Save for Web and Devices.

    Save as doesn't let you change sizes, so that can't be it. Do you really have to first use 'resize', then Save for Web? That seems cumbersome if you have hundreds of pictures to process.

    Is there really no way to go straight from a full size picture to a certain size/type/quality level in one step? Say taking a 2400x1600 pixel PSD image, and creating a 480x320 .jpg quality level 10 version? And then doing this as a batch operation on a folder of images?

    Of couse there is...

    Look up Batch Process and Photoshop Actions in the Help file.

    No one, absolutely nobody needs large images on the web.  That's why Save for Web was designed for web-sized images.

    Photoshop is working as designed.

    Tai Lao misunderstands my question. I am referring to the size of the image you begin before you produce a smaller web version.

    The problem is that Photoshop appears to have trouble handling large images for this process. Typically, you edit a large photo image. You don't want to resize it, but rather just make a web version (or several smaller versions). That's what this menu command is for, presumably.

    Here's how to replicate this: open a 20-30MB photo. Go to File:Save for Web and Devices. You'll get a dialog that says: "The image exceeds the size Save for Web & Devices was designed for. You may experience out of memory errors and slow performance. Are you sure you want to continue?"

    Now, I'm working on a machine with tons of RAM, lots of free disk space for paging, no issues there. No other PS operation complains. Why this one? There are lots of image files now that are above 10MB. PS should be able to cope.

    To be fair, despite this warning, it will generally work anyway.

    I just think in this price zone, PS ought to be able to handle today's large images gracefully. Canon's pro cameras now produce 20MB+ images.

    You are mistaken, Mr. Tai. The warning is inappropriate and should be either removed from the program or allow a “Don’t show this warning again,” option. Of course when saving an image for web I will want a smaller image, that’s why there are options to scale the image. I often start with a larger image when using Save for Web, with the full intention of scaling it down. Warning me is pointless.


    It’s as though the door to my house knows I only own a bicycle so it warns me whenever I leave the house with a large package that won’t fit on my bicycle, ignorant of the fact that I have borrowed my mom’s car.


    There are many improvements that Save for Web has needed since it was introduced. This warning is one. Another is that it often takes a long time to generate the preview before the user can enter any data, like the actual image size needed. The program takes several seconds to generate a useless preview of a too large image, rather than letting the use set the size first. It is also unforgivable that the presets, in both Illustrator and Photoshop, do not remember scaling.


    You are entitled to your opinion, Mr. Falkner, but I respectfully disagree with it.

    You can always post a feature request for Adobe to consider.  I do not need such a "feature" and I appreciate the alert message.
