How to split and rename PDF files in bulk

  1. Choose the source PDF from your device.
  2. Split it every N pages or enter complete, nonoverlapping ranges.
  3. Import CSV or TXT filenames and select the correct column.
  4. Verify every document-to-filename association before creating the batch.
  5. Download the locally generated ZIP and optional CSV manifest.

Strict document-to-filename validation

Export remains blocked when a mapping is missing, filenames collide after safe normalization, page groups overlap, source pages are omitted, or imported rows remain unresolved.

Visual matching prevents silent reassignment

Each group shows its first page, source range, imported row, proposed filename, and validation result together.

Private local batch processing

The source PDF, filename list, previews, outputs, and ZIP remain in your browser and are not sent to a PDFMech processing server.

Verified ZIP and manifest

Generated pages and archive entries are checked before success is reported. The optional manifest records each output filename and its source pages.

Split a PDF into Multiple Files and Automatically Rename Them FAQ

Are my PDF and filename list uploaded?

No. The source PDF, page previews, CSV or TXT data, generated files, and ZIP remain in your browser during supported processing.

What happens if a filename is missing?

Export remains blocked. The missing association must be assigned manually without shifting later rows onto the wrong documents.

Can PDFMech detect duplicate filenames?

Yes. Filenames are safely normalized and checked case-insensitively for collisions before any batch export begins.

How can I verify the generated files?

PDFMech validates source-page identity, checks every ZIP entry, and can include a CSV manifest listing each output file and its source pages.
