Android application to manipulate sd image from the site

Both ZIP and LZW are lossless compression methods. That means that no data is being lost in the compression, unlike a lossy format like JPG. You can open and save a TIFF file as many times you like without degrading the image. If you try that with JPG, the image quality will deteriorate more each time. So you can rest easy: using TIFF compression will not degrade your image quality.

TIFF can be a container for JPEG data. So… your point was?
