Reduce file size from 80MB to 5MB - jpg

[Krista]

I need to reduce a file that is 80MB to 5MB so that they can upload it to a card company.  Can’t quite figure out how to do it.  Thank you for your help in advance!

[Damien Symonds]

What file format is it saved in presently?

And what are its pixel dimensions?

[Krista]

When I go into Photoshop and look in “image size” it says 103.4M and 492 px - 7306px

That's pretty much meaningless.

What size is it on your hard drive?

[Krista]

26.4 MB - hard drive, same dimensions as above

 

correction to dimensions above - 4912 x 7360

Was this a typo, somehow?  Or is a REALLY long and skinny file?

[Damien Symonds]

By the way, in your thread title you mentioned 80MB.  Where did that size come from?

[Krista]

correction to dimensions above - 4912 x 7360 - just incase you didn’t see correction above

Thanks, that's more like it.

Next, can you show me a 100% crop from the image?

Also, when you saved the jpeg from your PSD master file, do you remember what quality level you chose?

[Damien Symonds]

I'm sorry, I can't hang around any longer.  I have to dash to get the kids.

I'm asking for the 100% crop because I want to be sure you've removed all the noise.   Noise is a HUGE factor in file size: https://www.damiensymonds.net/2015/08/about-jpeg-file-size.html

As long as it's clean, then all you need to do is choose a low enough quality level for the save, so that it's below 5MB.  It shouldn't be any trouble at all.

[Krista]

I’m sure I saved it at 12 quality.  I’ll go look up your 100% crop instructions now.

 

[Krista]

I figured it out.  Hope your kids are doing well.  Thanks for the help!

[Damien Symonds]

Yeah, 12 is ridiculous.

They're great, thanks. Hope you and yours are well too.

[Krista]

Just a follow up question  - you are right 12 is ridiculous...how should i be saving these then in photoshop.  I just started guessing on the pixel lengths for the above picture.  Is there a a place to look for what standard sizes are for each size?

 

I am off to bed but will check back in tomorrow morning.

[Damien Symonds]

To answer that, I need to know more about the purpose for which you're saving.  You mentioned a "card company".  What are you working on, exactly?

[Krista]

I sell digital images to clients.  The above client just happened to be making a graduation card on Minted.com.  How I can I be saving smaller files with still great quality for my clients.

 

Would I do it in bridge through the “image processor” or in photo shop?

The digital files that you're selling shouldn't be over 5MB anyway.  What quality level did you end up choosing, to get it under that mark?

Whichever suits your workflow.  They're the same in terms of quality.
