Remove “Metadata” From Your Files Before Sharing Them

Whenever you create, open, or save a file or document, that file will store information — known as metadata — that you had no intention of including or disclosing to others. Taking a conscientious “extra step” can prevent  embarrassment, and also make you a bit more secure. Here’s the “how to”.

Hidden Attributes and Tags Might Reveal More Than You Would Like

You may not be aware that the documents you generate, and the photos you edit on your computer are “stamped” (if you will) with little bits and pieces of information that the computer thinks are useful — called “metadata“. This metadata is not out in plain site for you to notice, but it’s there. Fortunately, it is not difficult to remove.

[note: “Metadata is not necessarily “bad”. Metadata is essentially there to help the computers do their jobs better and faster, and can be helpful to us as well.]

Metadata for a photograph would typically include the date and time at which it was taken and details of the camera settings, such as focal length, aperture, exposure. It would also contain any titles or keyword “tags” we’ve added to help us organize our albums. (If your camera/smartphone has “geotagging”, your location is pinpointed.)

Metadata for a document would typically include the date and time at which it was created, title, author, subject, number of pages, and the language of the text.

But the metadata will also contain the number of revisions, how long you spent working on it, (possibly) hidden markups/edits, who it is “shared” with, who else it’s been sent to, the Save path (which usually reveals your User Name), computer name, and more.

This can open you up to embarrassment (What? They took 4 hours and 16 revisions to write this ??? And why did they show it Joe?) and/or provide info a hacker might use to gain control of your PC.

Tip of the day: Before you e-mail off your file as an attachment, or turn it in to the boss, it might be a good idea to strip it of the metadata. To do this:
1) right-click of the file and select “Properties” from the context menu. In my example, I’ll use a Word document named BarbaraInvoice.doc.

2) Click on the “Details” tab, and look to the bottom area. Click on “Remove Properties and Personal Information”.

3) A new window will open. Here you will see two choices represented by radio buttons. ‘Remove it all’ is the default, but you can be selective by clicking the second button, and using the window scroll, and remove just certain tags.

4) Click “OK”, and the metadata is gone.

If anyone should know better than that, it should be IT Pros, working at a place like Yahoo..? Ya’ think?

One program that fixes everything. (I’d be out of a job!) Advanced SystemCare Free from IObit comes pretty close to fitting that bill. One click will help restore your computer to its youthful vigor, and keep it running smoothly.

Another Photo Shrinking Tip

Sooner or later – if you haven’t already – you will try to send or receive an e-mail attachment.. and bump into the problem of size limitation. (Usually, it is photos that give us the headaches.) E-mail simply isn’t the proper method for transferring large files, but there are tricks that can help you get those files where you want them.

I provided tips and solutions for solving these problems in this prior article, How to send big files (updated); and since it is fairly “in depth”, I highly recommend you click the link and give it a look-see.
Today, I want to provide you with another little tip for shrinking the file size of photos, so they are easier to send.

Because the common image format JPEG is already “compressed”, putting your photo.jpg into a Zip file will not shrink the file size enough to make it worth the effort. So, one must then mess with using an image editing program to “resize” the image and/or change the dpi “resolution” and/or select a poorer quality jpeg setting to get the Megabytes down to a e-mail-able size.

Tip of the day: Copy > Paste the image into WordPad, and Save the resulting .rtf file (Rich Text Format). Now you can right-click > Send To > Compressed (zipped) folder.
If you have never tried this technique before, you will be amazed at the size reduction.
(I know, it is a little strange to use a text program for pictures.. but it works!)

You don’t have to worry that your recipient will not be able to Open your file either. All PCs come with a text utility that can read/write .rtf. (WordPad is a Standard part of Windows, and it can be found in your Accessories folder.)

Today’s free link: 7-Zip File Compression Utility. The main features of 7-Zip:High compression ratio
Supported formats:

For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
Strong AES-256 encryption in 7z and ZIP formats
Self-extracting capability for 7z format
Integration with Windows Shell

Photoshop online– use the Web to edit pictures*

“Made You Look” is the marketing catchphrase for the new online Photoshop Website, and yes– I did take a look. Adobe Photoshop Express (Beta) is a Web 2.0 application for editing and sharing your digital images, and is seen to be a replacement for a program you buy and load onto your computer. It is — at this time, anyway — a free service (and surprisingly, has no ads).

I would be very surprised if you haven’t heard of Photoshop; it has been around so long, it has become a verb in today’s language (meaning “to create a fake image”). Photoshop is the tool which allows you to put your head on someone else’s body.. or make it look like you’re standing on the moon.. or remove your Ex from your old vacation pictures. (With the right starting photos, there’s almost nothing I can’t fake in Photoshop.)

Photoshop has long been considered the premier digital image manipulation program. As I discussed in this article, “Web 2.0” is all about us regular folks being able to ‘upload’ to the Web (and “share”/collaborate) instead of simply viewing (‘downloading’) content. And frankly, Adobe is not the first to the market of online photo sharing Websites, nor sites that let you edit your pictures once you’ve loaded them.. Picassa and Photobucket have been around for a while now (to name a few).

Considering Photoshop’s reputation, I wanted to know if Adobe’s online service had superior editing capabilities. To use Express, you must “join” the club, by providing an e-mail address and creating a user account. While you do that, you create a personalized URL (like, http://yourname.photoshop.com) where you can post your pictures in “galleries”, if you want to share them (which is not required). Once you’re a member, you “upload” your pictures, and you can now edit them, and organize them into galleries, e-mail them, or use them as images on (other) Websites.

The screenshot above shows the image editing screen. Those of you who have ever used Photoshop Elements will be very familiar with this interface. The editing options (left column) provide a thumbnail range above your original so you can see, and select from, adjustments. This makes ‘tweaking’ your image quite easy and straight-forward, and allows you to experiment without ruining your original.

Is this for you? Well, as it stands, I find that there are some basic image editing features which are missing (it is possible I just couldn’t find the menu..) such as image resizing and dots-per-inch adjustment. You can crop, but not shrink.. nor adjust file type or size. I am an advanced Photoshop user, and so I find the tools in Photoshop Elements overly simplified, and these even more so– which is precisely what many people want.

While this (at least, in its current state) tool will not let you paste your head onto a super-model’s body, or pose on the moon, it will let you smoothly and easily tweak your images, remove the red-eye effect, and share your pictures with far away friends and relatives. If you are not already using a similar service.. or are not satisfied with the one you’re using.. you should give this a tryout. It is very slick and easy to use. Click the link in the second sentence, and get started.
