I tried it 3 times and each time it starts off strong at about 200k download, then it drops to like 50k after a while.

"""With text files, size is less important because the files are full of “spaces” and can be compressed very tightly—a text file can be made at least 90 percent smaller, resulting in a high compression ratio (the ratio of compressed data to uncompressed data).
Other file types, like MPEG video or JPEG photos, hardly compress at all because they're in a format that's tightly compressed to begin with."""
But, if you get some compression, it will be expending image quality.
A technical explanation: when you decompress a image the pixel pattern never will be the same than the original one. Sometimes this is unnoticeable, sometimes not.
Example: An original file has 100K
After compression it has 30K
After decompression it has 100K again.
But the original pixel pattern had been changed forever.
