Question

png-8 greater than 8192 * 8192 in the current version of Photoshop?

I have Photoshop CS5, my PNG is 11,000 * 11,000 px and I want to save it with png-8.

If I save it with "For Web ...", then this is only for images with a maximum of 8,192 * 8,192 px. With "Save as ..." the image is saved in the original resolution, but only with png-24 - and thus the file becomes extremely large.

Is there a limitation of 8.192 px for png-8 in the current version of Photoshop?

How else can I compress such a large png (the usual online tools can only compress a maximum of 50 MB and my file is over 70 MB in size)?

Thanks in advance for a helpful answer

Open the "Save for Web" dialog
Change your output settings to the preferred format and quality
DO NOT interact with the size inputs
Click the "Preview" button in the lower left corner of the "Save for Web" dialog
Photoshop will generate the image at your original dimensions and open it in a web browser
Save out the generated image from the web browser

Works for me - You can thank Jordan Pagels for the info :-)

Sorry if I offended you, but to find a workaround we really need to know what you need and how to best get there. That's all.

You can't save PNG 8 at those dimensions, as you already found out. That's because PNG is a web format, not intended for print.

In Photoshop(!) you can not save it in png-8 - but in other (free!) Programs that works!

I say goodbye. I know now that Photoshop is the wrong program for me ...

Thank you.

Photoshop is not the problem – png-8 is not a sensible choice of format for images that are intended for print. (Edit: Though there may be exceptions, for example if the image is intended to look degraded/posterized/dithered/…, but in those cases it might still provide for better predictability and editability to try and achieve the effect in a layered file.)

What is the image’s content?

What is its Color Space?

Does it have transparency?

I think you need to explain what this is for. If this is for web - why does it need to be so huge?

It is NOT for web. It is for print.

I have just downloaded Photoshop CC. There I can choose between large, medium and small when saving in png - but the result is identical for a 75 MB file!?!

Even with the free software paint.net you can choose between png-8, -24 and -32 when saving - but it works there! At png-8 is from my picture a only 21 MB file!

I still don't get it. Why does it specifically have to be PNG-8? That's indexed color (max 256 colors), you're throwing out massive amounts of data. Do you need to reduce file size? Why?

I'm sorry, but this just doesn't make any sense. PNG is a web format.
