Arduino file compresssion

I am currently working on a project that requires creating and sending text files (~1.5-3.0MB) using a SD cards and bluetooth connections. I was wondering if the Arduino Uno has an compression capabilities that would allow me to reduce the text file size. The text files consist mainly of numerical data, about 640x480 data values per file. Any help would be greatly appreciated!

Thank you

No, but you are free to develop something.
