Decrypted IPAs have suspiciously low file sizes

An app I am trying to decrypt seems to have almost half the filesize as a decrypted IPA.

Decrypting the same app via CrackerXI results in a closer filesize of 700 MB, unlike 300 MB.

that's because these are packaged

@TBX3D CrackerXI decrypted ipa files are larger, does TrollDecrypt compress them unlike CrackerXI?
