convert current.jpg +profile xmp new.jpg --> lossless ?

[motivio]

Hi,
I'm removing the xmp information from some JPG files with the command:
"convert current.jpg +profile xmp new.jpg"

Is this a lossless action and will the new JPG file have the same quality???

Thanks and Regards,
JO

No it is not lossless; you can add a -quality 100 to try and keep the best quality.

I think my question could be also asked like:

Do I lose quality in an existing JPG file I add or change a profile in the file?

Is there any other way to remove the XMP profile and not losing quality in the JPG file?

Not in ImageMagcik. Image Magick is a raster image processor, NOT a profile processor.

Try looking at programs like jhead and such which are designed to modify profiles without decoding/encoding the image raster data.
