TIFF files are usually used for preparing files for printing. JPEG files are compressed files so that they take up less space on the computer and are ideal for using as graphics on the web. If you plan on printing out the pictures later and want good quality, keep them as TIFFs, otherwise if you just want to store a bunch on the computer to back up, change them to JPEG.

I'm sure if you don't have Adobe Photoshop you can always open the already scanned TIFF files in Gimp (google it!) and just save it as a JPEG. Hope this helps!

I'm sure Preview can do the conversion, just open the image and then select save as or export. If they are already in iPhoto, then iPhoto should also do the trick easily (export). Unless the size is a problem, i would leave them in TIFF.

One thing to be really careful of is working on jpeg images .. and saving them again and again. (say you want to crop them, fix colours etc) Everytime a jpeg is saved it recompresses the file and loses quality (jpeg is a lossy compression format and pixels are lost).
So best to work on them as tif files and then save them to tif (print) or jpeg (online) AT THE END.

You could also check out Automator. It can convert them automatically for you. Also, if you enable folder actions, and add an applescript to it, any file that you drop in will automatically get converted to JPEG or whatever.

If you drag your images out of Iphoto into another folder, Iphoto will automatically convert them to JPG.

JPEG at highest setting - TIFFS are used because if the image (TIFF) is 'bleeding' out of a box. Whatever can't be seen, doesn't get RIP'ed. Therefore keeping the PS (Postscript files) down to a minimum file size.

I ONLY use JPG (highest) commercially!

You were smart to save the original scans as TIFF (a lossless format). Burn a copy of those onto a CD or DVD to preserve them, then convert your working ones (I assume you're done editing them) into JPGs.

Maybe I'm stupid, but on OSX you can "open" TIFF using Preview app and "save as" it as JPEG in one click.
