Promise
NadirPatch.com founders team promise to do all the best to provide the tools using for free, as much as possible will be done to keep the tools free for use. The files processing gives heavy loading on server, the tools do complex manipulations, the server loading is rather high, unfortunately the 20 MB limit need to stay. But we will keep the work and promise to provide each tool use for free.
Files security and policy

When you open the page and uploading of first file is completed you have one hour timeline to finish the process, uploading other files, manipulate with tool and download ready new file. After the one hour is over, all uploaded files are removed from server and no ability to recover any of uploaded or created new file.
