About this utility
How to use Portable Filename Normalizer
Create a collision-safe cross-platform rename plan for pasted filenames without touching the filesystem.
What to provide
Enter one filename per line. Paths are treated as literal names and directory separators are removed.
- Paste, type, or drag and drop a supported text file into the input area.
- Choose the options that match your intended result.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
An original-to-normalized mapping with deterministic collision suffixes.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- All input and output remains in this browser tab and is never uploaded or saved. The plan does not rename files. Destination filesystems can impose stricter byte-length, normalization, case, or reserved-name rules.

Select “Load example” at any time to restore this tested sample.
