How to use, limits & privacy

Select up to 10,000 files. Run to see total selected bytes, extension groups and a per-file manifest in JSON and CSV. The report uses file properties without reading contents. It covers selected files only, not your entire disk. It does not detect duplicates, delete files, or modify them. Browser-provided modification dates may be unavailable or imprecise.

File inventory reads properties only. Byte Inspector reads bounded slices. Extension Renamer creates separate downloads.

Inputs are never uploaded. Results are rendered as text or a locally generated image. Original files remain unchanged. Changing input invalidates previous results.
