Under the premise of keeping the video quality acceptable, compressing the video file size is very beneficial. Because that will dramatically reduce the disk space required to store these video files; At the same time, this also saves a lot of bandwidth and time spent on uploading it to the online storage space. At this point, a video compression application is always necessary.

First of all, please note that: UHARC/GUI (finished in 2007) is far from being WinUHA (finished in 2005) with a similar alias 'UHARC GUI' (most software download sites mixed them up). It has a compression ratio even higher than 7-Zip - basically we are sure it's the only multimedia archiver in the world now that supports the maximum compression rate (UHARC/GUI > 7-Zip > WinUHA >> WinZIP/WinRAR).

The PSP supported game ROM formats are mainly ISO/CSO which generally have very big file size. PSP ISO Compressor is a fairly powerful and the most commonly-used PSP game image compression and conversion tool. It's simple, practical and fast along with fewer problems, we strongly recommend it for handheld game console players.

For some webmasters or web designers, most often they need to make the webpage image smaller, in order to get a faster network transmission (faster page loading and faster image downloading) and the corresponding lower bandwidth bills.
