About
In the digital age, file hygiene is not merely aesthetic; it is a critical component of data integrity and workflow efficiency. Disorganized file naming conventions lead to retrieval latency, version control errors, and systemic entropy. This tool acts as a deterministic transformation engine, mapping a set of chaotic input filenames Fin to a structured, semantic output set Fout.
Unlike server-side tools, this application operates entirely within your browser's local sandbox using the DOM File API. This ensures zero latency and absolute privacy - your data never leaves your machine. Whether you are a developer normalizing asset names with RegEx or a photographer serializing thousands of raw images, this engine provides the logic depth required for professional batch processing.
Formulas
The renaming process follows a strict transformation pipeline function T applied to each filename x:
The serialization index Si is calculated as:
If a collision occurs where x'a = x'b, a conflict resolution delta δ is appended to preserve uniqueness.
