(using ExifTool, preserves original file as backup) Jimpl will strip all EXIF metadata and location data recorded in the photo and you can download it fully cleared. Hint for convenience: If you are on Windows, you can apply a REG file to the registry, to install an entry in the context menu, so you can easily remove metadata by right-clicking the file and selecting the command.įor example (remember to edit the paths to point to where the executables are installed on your computer):įor JPEG,JPG,JPE,JFIF files: command " Remove metadata" Call me old fashioned, but when I remove something from a file, I want a file size the be smaller if not the same size. Use these tools to remove metadata like GPS location and other identifying information from photos and files you share. This leads me to believe that Imagemagick is encoding the data you want stripped away, and is storing it somewhere else in the file. If your image file uses little endian, some adjustments need to be made.ģ) When trying to use ImageMagick to strip exif data, I noticed that I ended up with a larger file than what I started with. Nikon has information after this which my program truncates.Ģ) Because this is for Nikon format, it assumes big endian byte order. Normally image programs read up to the first EOI marker found. They encode this data on to the end of the image file by creating a second EOI marker. Nikon's JPEG format adds somthing to the very end of each file it creates. The code below does the following:ġ) Gets the current orientation of the image.Ģ) Removes all data contained in APP1 (Exif data) and APP2 (Flashpix data) by blanking.ģ) Recreates the APP1 orientation marker and sets it to the original value.Ĥ) Finds the first EOI marker (End of Image) and truncates the file if nessasary.ġ) This program is used for my Nikon camera. This segment may be copied or deleted as a block using the Extra "Adobe" tag, but note that it is not deleted by default when deleting all metadata because it may affect the appearance of the image.I recently undertook this project in C. From the tag documentation: The APP14 "Adobe" segment stores image encoding information for DCT filters. The data in is from the file system and can not be removed, is the data defining the JPG (and thus can not be removed), and is a special segment that actually can be removed, but doing so may alter the appearance of the image. YCbCrSubSampling : YCbCr4:4:4 (1 1)Īs you can see there is still some metadata, but that metadata is all required.
