Rename PDF Files Using Text

Extract native text first, use the existing OCR pipeline only when required, then review every filename before downloading unchanged source PDFs.

OCR-derived low-confidence values are marked for review and cannot be included in the ZIP until approved. Invalid characters, blank values, long names, and collisions are handled deterministically.

Frequently asked questions

Does this change the original PDF?

No. It only changes the downloaded filename.

What if no match is found?

The item remains marked for review instead of being silently renamed.

Can scanned PDFs work?

Yes. The existing OCR pipeline can be used when native text is unavailable.

How are duplicate names handled?

Filename collisions are resolved deterministically.

Can I rename multiple PDFs?

Yes. Approved files can be downloaded together as a ZIP.
