If you are happy with it and you would like the support the developer, you can purchase the ad-free pro version.

Note : This is not an audio/video/pdf splitter or merger.
After splitting complex files (audio, video, pdf etc), individual files may be corrupt, and should be merged back to work as before.
Similarly, merging these types of files will only work if the files have been previously split.

The purpose of this application is to provide a way to split large files which are difficult to send/upload and deal with size restrictions and limitations. After splitting, the initial file can be recreated using the merger function.
Works for files of all types and sizes.
