Hi everyone,
If you regularly manage large media libraries, sanitize messy datasets, or prepare code assets, you know the pain: cloud batch tools hit file size caps, queue up slow uploads, and expose raw client files to the internet.
BulkFileFixer was created to eliminate the cloud bottleneck entirely.
By leveraging client-side WebAssembly and modern browser APIs, it processes directories, media folders, and code files directly on your hardware. You get the speed and volume capacity of a local script with the accessibility of a web app - no terminal setup, no software installs, and zero bytes leaving your system.
