How can I convert JPEG to RGB?

Question

I don't have photoshop... I have a macbook pro with iPhoto and anything i can download off the internet would help. The only problem is that I tried a converter online and it worked but then when I tried to download the image in RGB format it said my computer couldn't read the type of photo? Thanks for the help.

Answer 1

What do you mean by "RGB". RGB usually refers to the colour separation of an optical display. Red Green and Blue. There are many file formats which support images in this form, either as RGB32 or RGB24. Some examples would be PNG, TIFF, TGA, PBM, BMP, PSD. Jpeg is stored as YUV data, not RGB.



Sounds like you are coming from a Mac, (never seen iPhoto for any other OS, lol) so Preview will support PNG and TGA for sure. I think it can read BMPs and many TIFF images as well.



Many digital camera RAW formats are also RGB, but each one is different, so you really need to use the software that comes with your camera (or can hopefully be downloaded from the manufacturer) to read those.



But you say you want to convert TO RGB, FROM Jpeg...? As I say, what form of RGB?



Googles Picassa will convert Jpegs to many of the file formats I listed above, and will display, and allow you to edit any of them.

Answer 2

Rgb File Format

Answer 3

There is no such thing as a RGB file format. There are only .jpg or. tiff formats in RGB mode. You need to redo the online converter and get it to save the file back into the same original format. Your computer doesn't read whatever format you created online, but it has nothing to do with it being RGB or otherwise - it's all to do with it not being a .jpg. Save it as a .jpg again, and away you go.

Answer 4

It's a file format developed and used by Silicon Graphics International Corp. or SGI for short. If you have a jpeg and need to convert it to RGB format. (Like Senior Pictures) you can go to http://www.xnview.com/ and download this program and you will be able to convert the file.
