Features

Everything a document goes through, in one place.

Replace the converter tab, the e-sign subscription, the shared-drive scramble and the “which version is final?” email thread.

Answers with receipts

Ask anything about a contract, filing or report. Every answer links to the exact page and passage, highlighted in the document.

A searchable knowledge base

Every upload is indexed page by page. Search or chat across your entire library, in any language, including scans after OCR.

Extraction you can trust

Pull key terms, deadlines, obligations, parties, financials and tables into clean spreadsheets. Risk flags are checked against your own playbook.

Real PDF editing

Click any line to change it. Add text and images, highlight, and redact for real. Redacted pages are flattened, so hidden text is gone.

E-signatures built in

Place fields, route to signers in order, send reminders. Every signed PDF ships with a certificate of completion and a SHA-256 fingerprint.

Automations

Risk review on upload, weekday digests, renewal reminders 60 days out, and Slack or Teams webhooks. No-code, and it runs while you sleep.

Convert anything

Word, Excel, PowerPoint, text and images to PDF, and PDF back to Word, Excel, PowerPoint, JPG, PNG, WEBP and TIFF, with the formatting intact. Camera scans to PDF. Merge, split, reorder, watermark.

Team-grade control

Check-out locks prevent conflicting edits. Hand-offs keep ownership clear. Every version is kept, with a full activity trail.

Document requests

Collect NDAs, W-9s and certificates from clients through a secure upload link, with due dates and reminders. No account needed on their side.

How teams use pdftek

From inbox to executed, without leaving the page.

  • A vendor MSA lands. An automation extracts risk flags against your playbook and pings #legal.
  • Counsel asks “what's our exit path?” and gets the termination-for-convenience clause, with a link to page 2.
  • They check the document out, redline the notice period in place, and save v3. Nobody else can overwrite it.
  • They hand it to Contracts, who sends it for signature in order. Reminders go out automatically.
  • Once it's fully signed, key terms go to the tracker, and a renewal reminder is set for 60 days before expiry.

Workspace isolation
Every request is authorized against workspace membership and role.
Immutable versions
Each save is a new version with a SHA-256 fingerprint. Restore any version at any time.
True redaction
Redacted pages are rasterized, so the underlying text is removed, not just covered.
Audit trails
Activity logs, signer IP addresses and timestamps, and certificates of completion.
Private OCR
Text recognition runs in your browser. Scans never go to a third-party OCR service.
Self-hostable
Run pdftek on your own infrastructure, with your documents on your disks.
Security

Built for documents you can't afford to leak.

Contracts, financials and patient records need more than a free converter site. pdftek keeps your files in your workspace, logs who touched what, and can run entirely on your own servers.

Questions, answered

Does the AI make things up?

pdftek answers only from your documents and cites the page for every claim. Click a citation and the passage is highlighted in the viewer, so you can check any answer in seconds.

Can it read scanned documents and other languages?

Yes. The assistant reads scans directly, and in-browser OCR adds a searchable text layer in 13 languages. Search, read-aloud and conversions work across 40+ languages.

Are the e-signatures legally binding?

pdftek captures consent, signer identity via unique email links, IP addresses and timestamps, and adds a certificate of completion to the signed PDF. That's the standard evidence under ESIGN and eIDAS for simple electronic signatures. Check your jurisdiction's requirements for regulated documents.

What happens when two people edit at once?

They can't overwrite each other. Editing checks the document out to one person, and teammates see who holds the lock. You can hand it off or check it back in at any time, and admins can release a stale lock.

Can we host it ourselves?

Yes. pdftek ships as a single Docker image with a built-in database and file storage. Bring your own Anthropic API key for the AI features and your own SMTP server for email.

Your documents, finally under control.
