Each time we send an image attached to an e-mail or we upload one on the internet, we need to ensure that our personal data & files are not going away in the same time with it.
jStrip is a free tool to reduce the file size of JPEG images without sacrificing image quality. High-traffic websites with many JPEG images can benefit from decreased bandwidth costs. Less hard disk space will be used by image collectors.
jStrip works by removing unneeded data from JPEG files. This data is unused by web browsers and image viewing software. jStrip does not re-compress an image, so there is no image quality loss.
Features
jStrip removes the following from JPEG files:
- Comments (optionally)
- EXIF Data (optionally)
- JFIF Header (optionally)
- Photoshop Image Resource Block (optionally)
- ICC color profile
- Adobe APP14 tag (optionally)
- XMP data (optionally)
- Extra bytes at end of file
- Extra bytes or header at beginning of file
- Extra bytes between JPEG blocks
- Application-specific APPx blocks
- Photoshop thumbnails
- Any other unknown blocks in the JPEG files
jStrip also has the following features:
- Option to retain original time-stamp of modified files
- Ability to process a single file, or batch processing, including recursing a folder tree
- Option to attempt to clear read-only bit
- Includes a full help file
- Allows browsing and processing of UNC paths
- A command line version for batch processing
- Can change case of filenames, and change %20 and underscores to spaces in filenames

* Windows 95 and NT4 require IE 4 or greater for the HTML help to work correctly.
Extract the content of the archive that you downloaded from here (click) and then start the installation process by clicking setup.exe.
After installation, run the program and the open the configuration window (File | Options ).
In the General Tab you are allowed to activate the option Clear read-only bit which suppresses write protection, if any.
In File Selection Tab , check Select files (classic interface). This enables you to choose the files later.
The settings for the information that must be eliminated from an image are located in the JPEG Tab.
By using the default settings of the application, jStrip also deletes the ICC color profiles and the information that is added when a program like Photoshop was used to edit an image.
Confirm all the changes with a click on the OK button.
Now select from the tree structure the folder that contains the images and click Start to clean the files.
A direct effect to the files is that their dimension will be significantly decreased.
As an advice, make sure that you work with copies of the images, because the application overwrites the new files to the old ones and in this way there might be a possibility to lose some important data. If you want to edit the picture once again or you want to put them back on a camera, it would be better to remove the specified information.
