Trust check
How to verify no upload
Open your browser Network panel before choosing a PDF or image. Add a file, export it, and inspect the requests. The tool may send anonymous page/tool events, but it should not send PDF/image bytes, file names, page text, thumbnails, or local paths.
Newsletter signup only runs if you enter an email after export. The PDF download itself is not gated by signup.

FAQ
What this tool does and does not do
Does Private PDF Workbench upload my PDFs or images?+
No. The V1 tool reads and writes files in your browser. Entroparc does not receive PDF bytes, image bytes, file names, page text, thumbnails, or local file paths.
Is export free?+
Yes. You can download the edited PDF after local processing without creating an account or joining the newsletter.
Can it redact text or edit PDF text?+
No. Redaction, OCR, compression, password tools, and PDF text editing are intentionally excluded until they can be handled correctly.
Is the signature tool a legal e-signature?+
No. Sign / Mark adds a visual signature stamp only. It does not create a cryptographic or legal e-signature.
Which PDFs need extra checking after export?+
Check files with forms, bookmarks, attachments, existing digital signatures, unusual page boxes, or very complex document structures before relying on the result.
