I shoot using a medium format camera in its raw file format (Phase One 100mp . iiq files). Photoshop will not open this file type on its own and converting to DNG for processing is out of the question for the amount of work I need to get through.

1. Zip It. If you need to send a really big file, or lots of little files, one neat trick is to simply compress the file. This means, you're sending the actual PDF or PSD, or whatever, but you're compressing the data so that the file size is smaller.

JPEG compression works by identification of "similar" areas of color inside the image and converting them to actually the same color code. For example if you have an image that is 24-bit color this means each pixel of the image should be able to store the color value out of 16,777,216 colors.

To add to what the others have said - file size from jpeg compression is image dependant. Some images compress really well, others result in bigger files. Use Export save for web (Legacy) and adjust the compression slider whilst looking at the image in the preview.

The file size is smaller but the original data is now gone forever. This is why lossy compression is able to compress to smaller file sizes then lossless. Lossy file formats include: MP3, MP4, AAC, WMA, Ogg and image formats such as JPEG (can be lossy or lossless).
