Image Compression

[dBradford]

Hello everyone,

This is my first post here so I am unsure of this is in the correct Thread or not, if not please kindly point me in the right direction.

So, my problem is this: I am compressing .jpg images using ACDSee Pro 10, the images reduce successfully, and I have them replace the original image. The images are reduced by about 60%. Now, after compressing the images, I move them to a network drive where the original images are located, I tried a few methods, The first method I tried was simply moving all the compressed images on to the network drive(drag and drop) and select replace all, after doing so it does successfully replace the images, HOWEVER it is taking up MORE space on the drive than before the images were compressed! I have also tried compressing the images directly on the network drive and the end result is the same, I also tried deleting the originals first then dropping the compressed images in, alas I am left with the same result, more space on the drive is taken up than before compression of the images. Does anyone have a clue as to why this is happening?

This is a work project and the drive is darn near full, so this is quite important and my boss is on me about fixing this issue as soon as possible( have been working on this for weeks now)

Thanks for the help,

I believe the reason you are having this issue is due to the fact that the jpeg aka jpg format is already an image in compressed form. Compressing images even further would likely reduce their quality below acceptable limits, hence the reason why your images are remaining at basically identical sizes when compared to the original.

Really the only fix I can suggest for this is to get a bigger storage drive tbh. If your boss cannot be arsed to buy a 2TB HDD for ~100ish dollars (and that's in Australian Dollars, in US it'll probly be something like 60-70), then I'm sorry but he/she is way too much of a tight arse.

Thanks for the reply, the images are .jpg format, but i am able to reduce their size by roughly 60% without any noticeable quality loss. The images are no doubt getting smaller in size, but I do not understand why they would be taking up more space than before the compression..

What are you using to measure the used disk space?

 

[dBradford]

the details of the file in file explorer, also through details within ACDSee

 

[dBradford]

for the disk space on the network drive, I am looking at the properties of the mapped drive.

Try using Windirstat and see if you still see the same anomaly

It's running, may take a while. I will let you know the results upon completion.

Is there any sort of built-in backup functionality of the network storage? Its possible when you put the original uncompressed images in the network storage a backup copy of those are made. Then when replacing them with the new compressed images the backup copies still exist as well as the newly compressed copies.

Just shooting guesses.

Could be Shadow Copies if that's the case.
