Corrupt JPEG data: 34608 extraneous bytes before marker 0xda

Code: Select all

identify: Corrupt JPEG data: 34608 extraneous bytes before marker 0xda `blah.jpg' @ warning/jpeg.c/JPEGWarningHandler/346.
I've inherited a lot of JPEGs which have some extraneous information in them. Without recompressing the images, can ImageMagick strip these extraneous bytes without losing metadata?

If IM can read the jpgs, then it will decompress and recompress to make the output. You will likely need some other tool. see http://www.imagemagick.org/Usage/formats/#jpg_non-im
