Preview first, create copies second

Bulk Filename Fixer

Normalize inconsistent filenames or create a numbered sequence, inspect the complete mapping, then download renamed copies without touching the originals.

Normalize mode uses Unicode NFC, lowercase letters/numbers and dashes, preserves extensions and resolves collisions deterministically.

Preview consistent filenames across a file set

Bulk Filename Fixer helps when filenames contain inconsistent spaces, separators, capitalization or numbering and you want a predictable naming plan before creating corrected copies. It is useful after a folder review identifies naming inconsistency that is genuinely unintended.

No in-place rename

A browser tool should not pretend it safely renamed files on your disk. TaskThimble creates a rename plan and, when you generate renamed copies, those copies can become the current local file set while the originals stay unchanged and remain recoverable in local history.

Review the mapping before generating copies

The preview shows how each source filename maps to its proposed output name. Check for collisions, lost distinctions and unwanted changes before creating anything.

Business identifiers need extra care

Filename normalization is syntactic. If a filename contains a meaningful SKU, version, case number, contractual reference or externally required naming pattern, verify the preview before creating copies.

Normalization is not a universal naming standard

A consistent pattern can make a set easier to manage, but the correct convention depends on the destination and business context. Use explicit client or platform requirements when they exist.
