Tiff is good. Even with LZW it is lossless.

Well, yes. That’s the point of "lossless".

However, once saved into JPEG, the image doesn’t lose anything again unless you re-save it in a lossy format. Images don’t degrade unless you do something to them.

To restate,
o you download photo.jpg
o you edit this file in some application
o don’t resave as newphoto.jpg (though most of us wouldn’t be able to see the
degradation); instead, ‘Save As’ newversion.tif.
o edit the tif, and only go back to the jpg if you mess up the tif.
