This is not fully offline: extracted text is sent to the configured Worker. Summaries can omit or misstate facts and must be checked against the PDF.

Frequently asked questions

Is the PDF uploaded?

No PDF bytes are sent, but the extracted text is sent to the AI service.

Can it summarize scans?

Run OCR first because image-only pages contain no extractable text.

PDFPerch processes files locally unless this guide explicitly identifies a cloud-dependent feature. Always keep an original copy and verify critical output before submission, printing, signing, or accounting use.
