P: Remove the 8192px limit on Save for Web [2013]

I've found a small workaround on this issue. What Photoshop does is remember the settings of the last time you Saved for Web on your file by default. I've found that only when photoshop is remembering these settings, and your settings were for a png, will it prevent you from saving another png at 100%. But if you confuse it a bit, you can get around it. Basically, you have to change Photoshop's memory to a jpeg output instead of png.

Here's what I did:
Open file, Save for Web, change whatever settings photoshop is remembering to a jpeg output (quality level doesn't matter), then press Done. The UI goes away and you're back in your file. Now, go to Save for Web again. As you'll see, for some reason Photoshop will allow you to output a jpeg at 100%. (It might still say 33% or 54% or whatever in the Image Size box, but just ignore it.) Save your file and check the dimensions. If you need a png, you can do the above, but on your second time in the Save for Web UI change output to png. But, remember that the next time you Save for Web on that same file, Photoshop will not let you output at 100%. You'll have to change the memory to jpeg again.

The pixel dimensions on my project are: 725 x 24,164

Adobe: When you lift the limit don't be stingy! I just ran into this wall unexpectedly. After checking my doc it was 23,195px tall. By emerging responsive standards it didn't seem unusually long when flicking through on a mobile phone. I would just give us more than anyone thinks we can use within the capabilities of your average modern workstation.

Hello, I found that this problem is still there.

I made a screenshot of a responsive site (>8192px in height) to make some quick modifications and I wanted to export the modified sections with slices but I couldn't due to this limitation.

Any fix expected?

Thank you.

Have you looked at Adobe Generator instead of Save For Web?

(Check out the Loom SDK video, above, to see something neat with their sprite sheets or the StandIn example for Mobile, below)

Indeed running into the same limit. I'm trying to slice up large backgrounds for mobile devices much bigger than the 8192px limit. Please lift this limit.

Good to know. Could be made easier in the UI. Thanks

OK, thanks for the background - that should make it easier to justify with product management.

FYI - Photoshop's PNG compression and SFW are the same - the difference is that SFW doesn't include metadata unless you tell it to. And Photoshop's PNG compression is still comparable to PNGCrush results, unless you include modes that Photoshop cannot support (like indexed transparency).

Amending a massive sprite sheet for a website. Both standard & retina resolutions. Canvas size for retina is over 10,000 pixels wide.

Save for web functionality (required to compress the png sufficiently) does not allow saving of images wider than 8192px - it automatically scales them back to this maximum without much wanring.

Forced to save out using 'save as' function as a .png file then use external tool for compression - which does a much better job at reducing file sizes also BTW.

In the age of retina resolution images and using sprite sheets in CSS for larger sites, these limitations need removing, and photoshop's compression abilities also need to up their game.

Now, we need more detail on just what you're trying to save, and what you are trying to do with those images.

In the age of sprite sheets, surely it's time to remove the 8192px limit on save for web? Keep getting stung by this..
