: Saving large PSD as JPG I have a 180cm × 900cm document in 300dpi RGB 8-bit and I want to save it as a JPG, but when I try to "Save As", the only available choices are PSB, RAW and

@Harper654

What will be the final print size? And how will you be sending them the image? I assume FTP, because there will probably be size restrictions for emailing it.

Tiff is probably the best output format. Or else pdf. Or if the final print size will be small, you could probably get away with a smaller jpg.

Even you asked for a .jpeg, i can assure you that .tif will do all the things way better - even Facebook best practices encourage .tif upload for high quality images.
From that size (180cm × 900cm) i can tell that you need it for print and DTP work. Normally, print factories will ask you for a .pdf to keep the color profile intact and the text as a vector but when that is not possible, .tif is the alternative.
You also have the advantage of saving the .tif with layers for future modifications at the print factory or without them for fast trade.

With 300 dpi the file is too large to produce a jpg image but you can produce a png file out of it. Otherwise you can decrease the resolution into 72 dpi and save as jpg .

The JPG format has a pixel size limit of 65,535 x 65,535 pixels. Photoshop however limits JPGs and most formats to 30,000 x 30,000 pixels.

For any images larger than 30,000 x 30,000 pixels you are stuck with the PSB, RAW or TIFF formats, there's no way around that.

From Photoshop Help / Saving Images:


Photoshop supports documents up to 300,000 pixels in either dimension and offers three file formats for saving documents with images having more than 30,000 pixels in either dimension. Keep in mind that most other applications, including versions of Photoshop earlier than Photoshop CS, cannot handle files larger than 2 GB or images exceeding 30,000 pixels in either dimension.


A 180cm x 900cm image at 300PPI is 21,260 x 106,299 pixels. Which is way too big to save as a JPG and I suspect bigger than you need.

For more realistic printing dimensions, read through this related Q&A:
I need to print an image at a certain size. What dimensions and resolution should I use?

If you really need a JPG at that size and resolution you will need to break the image in to smaller sections, but I suspect you can probably work at a lower resolution.
