Workflow

Execution Pipeline

Three local steps from messy files to organized names.

  1. 1

    Load files

    Drop or pick a batch — everything stays in browser memory, never uploaded.

  2. 2

    Preview & transform

    Apply patterns, RegEx, or Smart OCR and review every rename before you commit.

  3. 3

    Apply & export

    Confirm once — rename in place when you pick a folder (Chrome/Edge), or export a ZIP for uploaded files.

Trust & Security

Your Files Never Leave Your Device. Ever.

Local-first by design — rename, preview, and apply without sending a single byte to our servers.

Local processing: Rename logic, OCR, and previews run in your browser tab using WebAssembly and in-memory buffers — not on a remote VM.

No backend for files: We do not operate an upload endpoint for your documents. There is no server copy to breach, subpoena, or leak.

You control apply: Every batch requires explicit confirmation before renames are applied and exported. Preview first, apply when ready.

Powerful tools

Built for high-volume, real-world batches.

Rename thousands of files with pattern templates, RegEx find & replace, and local Smart OCR — all with live previews before you apply.

Pattern rename.
Template tokens for sequences and dates rename thousands of files in one pass — sequence + date tokens, folder-aware grouping, and dry-run validation with live previews.
Find & replace with RegEx.
Clean noisy names with plain text or full regular expressions — RegEx capture groups, batch-wide replace, and safe-character enforcement with group-aware previews.
Smart OCR beta.
Extract dates and labels from PDF and image content with an in-browser Tesseract pipeline — confidence thresholds and manual approval before every apply.
