| Each file is compressed into separate archive and total size is a sum of those archives. |
| Test files are not available online (with exception of PSD). |
| Compression and decompression speeds computed using Timer 3.01 by Igor Pavlov (global/wall time) and current version of PexTimer by LovePimple. |
