PSD huge size even tho it has nothing huge in it......?

Hi,

 

So basically i have PSD that is 1080x1920, 72 ppi, Working RGB profile, 8 bits. Nothing unusual.

It has about 24 layers, all of them variously resized photos. The folder with the photos says 50MB, while the PSD is showing circa 7 GB??? When i delete all the layers it goes to 11 MB, so where is the problem?

I tried to do frame by frame animation, but i created different PSD with completely different photos and without converting it to video timeline and it was the same problem even tho the photos were also not anything big, so the video is not the problem, niether is the file itself.

 

There is no way this PSD should be this huge. Anyone has any advice?

 

Thanks.

Correct answer D Fosse

yes, but the problem is, i didnt change any settings and never had this issue with files before. so im not sure jpeg decompression ia at fault. and the images are from stock so im not sure if they compress the jpegs that heavy.

 

If i rasterize the layers the decompression should go away tho right? since it stops storing the full original data of the photo/layer?

The size reduction with jpeg compression is dramatic! A typical, normal quality jpeg will be around 2 - 5% of the full native size as PSD or TIFF. At a steep price, of course, but the sheer effectiveness is probably the main reason the jpeg format still survives despite the serious drawbacks.

 

No, the decompression doesn't go away if you rasterize. If you put this in a PSD, it's no longer jpeg-compressed, and so it's ten to twenty times bigger.

 

As Dave says, PSD/PSB/TIFF can also be compressed, but non-destructively and a lot less aggressively, so the size saving is nowhere near as much.

Are the layers smart objects? If they are, each smart object has its content stored at whatever the original size was, regardless of the 1920 x 1080 final document

    Hi Dave,

    the layers are all rasterized. Even tho Smart objects would size up the document, the original photos are 50 MB total, so even with smart objects the PSD shouldnt be 4 GB. I worked with a lot bigger photos and multiple very complex smart objects very often and never had a file this inflated up until now. Even with this latest Ps update.

    Are those other files jpegs? If so they will be heavily compressed (even the highest quality jpegs use extensive lossy compression) to the extent that a PSD which is lossless will not be.

    OK, its 4 GB, not 7, my mistake, somehow it got converted into 16bits when i tried to fix this, its 4 GB on 8bits

    this didnt solve anything, i just corrected my initial info, the file is still about 100x bigger than it should be 🙂
