File Organizer — Rename, Sort and Find Duplicates

Short answer: To organise files, select them, review the suggested names, categories and duplicate flags, then edit names before downloading a ZIP. QuickMerge processes the files in your browser and keeps the originals.

Drop a batch of files. On-device analysis reads each document, suggests a real name (not “scan_0423.pdf”), sorts it into a category, and flags exact and near-duplicates — then hands you renamed copies in a ZIP. Nothing is uploaded.

A checked example

Synthetic examples checked in Chromium on Linux, September 9, 2026. The HEIC input is a licensed sample.

Inputs scan-0001.txt, copy.txt, revision.txt and note.txt produced invoice names beginning invoice-2026-09-01-Orchard-invoice, with numeric suffixes for repeated names. The first two files were exact duplicates; the revised invoice was marked similar to #2. The meeting note was classified as document and proposed as Garden-meeting-agenda.txt.

The first name was edited to reviewed-orchard-invoice.txt before saving the reviewed ZIP. Reopening confirmed four copies with original contents, including the duplicate. No original was renamed or deleted.

Frequently Asked Questions

Is this “AI” or a gimmick?

It is deterministic document analysis: cryptographic hashing for duplicates, word-overlap similarity for near-duplicates, keyword scoring for classification, and layout heuristics for naming. No cloud model receives the document; required processing libraries still need to load in the browser.

What counts as a duplicate?

Files with byte-for-byte identical content are flagged as exact duplicates even if their names differ. Documents whose extracted text overlaps more than ~82% are flagged as similar — typically re-exports or minor revisions of the same document.

Which files can be classified and renamed?

PDFs with a text layer and plain-text files. Scanned PDFs without text can still be checked for exact duplicates by their hash — run them through our OCR tool first to give them a text layer. Images are included in duplicate checking too.

Are my files modified?

No. The downloaded ZIP contains exact copies of your original files under the new names. Your originals on disk are never touched.

How do I rename a folder of scanned documents automatically?

Load the batch and let the analysis read each file; suggested names come from the content, so scan-0001.pdf can become something you can search for later.

Are my documents uploaded for analysis?

No. Reading, classification and duplicate detection all run in your browser. For a batch of invoices or contracts this is the whole point.

Review suggested names and duplicates before saving

Analyze a batch of PDFs, TXT files or images, edit proposed names and download a ZIP of copies. The tool reads files locally in the tab; it does not monitor folders or rename originals.

How names are proposed

PDF analysis reads up to the first three pages and looks for a title on page one. TXT analysis reads up to 20,000 characters. Date patterns and category keywords contribute to the proposed name. Scans without a text layer and images get weaker filename-based suggestions; OCR is separate.

Exact and similar have different meanings

Exact duplicates share a SHA-256 digest. Similarity compares sets of words longer than three characters in sampled text and flags overlap above 0.82. This is not visual comparison. A changed amount or a later PDF page can matter even when files are flagged similar.

Keep the review reversible

Inspect each source, edit proposed names, then export. The ZIP includes all analyzed files, including flagged duplicates. No files are deleted. Reopen the copies before manually reorganizing originals.
