With the binary split and merge web application you can easily split the input file into several segments. Likewise, if you have several file chunks, this app can merge all segments. Please adjust the settings for each part before operate.
Please wait for the app to loads completely, then start using the app by adding a file(s) to the designated area (top section). For the split operation, you only need one file and for the merge operation, more than two file-pieces are required. Once you import the file, please adjust the settings before the operation. For the split task, all the settings are available on the bottom left side of the app. Likewise, for the merge task, settings are available on the bottom right side. Please note that, once you import your files, wait for the import operation to finishes before pressing on the split or merge buttons. When the operation is complete, all the resulting file(s) will be downloaded to your machine.
