WebP format: webp package provides webpmux command, which manage XMP/EXIF metadata and ICC profile.Summary of the bug: According to the man page, the -metadata option can be used to set or remove the encoder tag on the output file.To remove only GPS data use exiftool -gps:all= -xmp:geotag= *.jpg. If you prefer Exiftool, you might find useful creating an alias to exiftool -all= *.jpg & rm *original, or with -overwrite_original option.Metadata Cleaner: Desktop app to view and clean metadata in files (not only images).Alternatives: jhead ( only for JPEGs) and exiv2 ( man suggested on Wikipedia).mat2 (Metadata anonymization toolkit v2): Removes metadata from a lot of formats ( -list).You might ask yourself if these costs are noticeable or relevant in your case.Īnother tool about steganography on images is steghide. Compared with diff -y newimage.jpgĪlso, to avoid losing color profile ( ICC metadata, which causes richer colors ): convert image.jpg profile.icm & convert image.jpg -strip -profile profile.icm newimage.jpg Since you will lose the orientation metadata, maybe you'll want to mogrify -auto-orient image.jpg first.ĪFAIK the only difference with exiftool is that mogrify won't remove this metadata: strip strip the image of any profiles, comments or these PNG chunks: bKGD, cHRM, EXIF, gAMA, iCCP, iTXt, sRGB, tEXt, zCCP, zTXt, date. With imagemagick package installed you can do this ( not only for JPEGs): mogrify -strip *.jpg # Optionally: -verbose To read identify -verbose image.jpg | grep exif Instead of Exiftool, to handle Exif metadata (IPTC, XMP and ICC image metadata also) I found Imagemagick more useful and command easier to remember.
