A collection of browser-based utilities designed for hardware enthusiasts, retro-coders, and BIOS modders. These JavaScript-powered tools allow you to perform common file manipulations – such as splitting, merging, and doubling – directly in your browser without uploading your data to a server.
Binary File Tools (Even/Odd Splitter, Merger, & Doubler)
Split a File
Upload a binary file, and it will be split into even and odd bytes. Downloads will start automatically after processing.
Note: High = Odd, Low = Even
Merge Files
Upload the even and odd binary files, and they will be merged by interleaving bytes (odd byte, even byte, etc.). Download will start automatically after processing.
Double File Size
Upload a binary file, and its content will be duplicated (repeated twice) to create a file twice the size. Download will start automatically after processing.
