I have compressed an image in python2.7 using PIL library like this:
picture.save("Compressed_"+file,"JPEG",quality=85)
Can I decompress it? I have searched so many sites, but couldn't find decompression related information.
I have to compress an image (should reduce file size) and decompress it back,what to do?
No.
JPEG use a lossy compression method to do compression, which means there will be some data lost during compression. This data lost is irreversible.
You may try some lossless compressing image format, for example PNG.
