About how much file space does metadata add to a file? I have some friends who strip MD from thier files because they say it add too much space. I say the extra spave is tiny unless you have extensive and detailed info, descriptions, etc. in the MD.
For a saved jpg that is around 200 kb I would guess basic MD is probably a kb.
Any thoughts?
It is not easily determined as each image is not the same. When you click Save As the program tries to estimate it.
If you use save for web you can choose to exclude the metadata. If you saved the same file with same resoultion with and without metadata would think you could find out.
If you do this report back your findings as it will be of interest to others.

Just tried it quickly on a file that saved as jpeg Max and 1,8 MB large and normal metadata with description, copyright, exif and a few keywords.
original:
1.781.638 bytes
second test file (select all, copy, create new document, paste - same file and size but stripped from metadata):
1.772.431 bytes
Third test file, same as before but now with also deselect sRGB color profile attached to the file (a very bad idea and to my opinion stripping metadata is just as bad but that aside)
1.775.566 bytes.
Strangely enough without the sRGB profile the file is again a bit larger but different color profiles can add very different sizes to the file.
Like Curt said, no image is the same and yes, metadata is usually a matter of a few kb's, some specific colorspaces can add far more to the size.
Bottom line:
Nowadays space is really not an issue anymore, on the other hand, preserving quality files for the future should be an issue for everyone.
The price of a good quality 1TB Hard drive (even with higher prices of this last half year) are still less then a tenth of the price you paid for a Compact Flashcard sized 128 MB 10 years ago....
Keep your originals in as good a quality as you can and if needed distribute files at the sizes needed (and save for web without metadata can create very small files with good screen viewing quality) but be sure to have your originals in good quality and also have a proper back up of them ![]()

I, too, did a little experiment. Took a jpg image in PS and did a Save for Web and Devices. One save with metadata and one without. Both were saved down to around 745 KB. The metadata only made a difference of about 3 to 4 KB. Nothing to worry about and i see no reason not to save the metadata. My friend tells me that it takes too much room and most Professionals strip the metadata. I totally disagree, especially with large hardrives widely and economically available. I think my friend is crazy
I guess if you save down to a very tiny file size like 80 KB the metadata will take proportionally more room but think those tiny file sizes are not necessary these days.
Appreciate all the comments/info!
most Professionals strip the metadata.
If a 'professional' should do so I would not call it a professional.
Without metadata you have no copyright info, no description, no keywords.
You are not likely to earn money if no one can see who has copyright of the image and if they can't find your files at all because there is nothing to look for so not even a change to earn money and therefore not able to be a pro.... ![]()

I cannot put a Description in without Bridge giving me an error message that it cannot write to my file.
Sounds like a permission error from the OS. External drive?
Right click on Bridge icon and start as "run as administator". If this works you need to find the permission problem.
Might check this past post to see if you have ownership of your HD.
The key to solving this issue lies is understanding that in terms of Windows 7 Security, every internal or external hard drive, plus folders, sub-folders and files thereon has an OWNER. Also each OWNER has a certain level of PERMISSION to do things such as moving files to a different folder, deleting or re-naming them etc. If you try to do things that you don't currently have Permission to do, that is when you get an ‘Access Denied’ error message. Also your system has an Admistrator or Administrators and at the outset you need to ensure through the Control Panel that you are listed as one of them. .
If, like me, you didn't realise these things, (and why would you if Microsoft or your computer or hard drive suppliers couldn't be bothered to really make sure you knew about them), then trying to fathom the ‘Access Denied’ problem becomes a stressful and frustrating nightmare as I can testify having spent a week at it!
The steps that I took to resolve the issue and which I believe now constitute the 'Correct Answer' are as follows:
First select the folder in finder and choose cmd + i or Get Info. In the info window at the bottom the permission are showing, it should state read and write permissions for you as user.
Also open Apple Disk utility ( in the application folder / utilities folder) and run a check and repair permissions on your start up disk
