Kinode PDF
The PDF editor that never sees your files.
A complete PDF editor that runs entirely in your browser. Edit text, draw, highlight, whiteout, and rearrange pages with nothing uploaded, then sign documents with real X.509 digital signatures from the Kinode Signing Authority and verify them in one click.
What it does
Most PDF editors ask you to upload the document first, which is a problem when the document is a contract, a medical record, or a term sheet. Kinode PDF runs entirely in your browser. Text edits, freehand drawing, highlights, whiteout, images, and page operations (rotate, reorder, delete, merge, split) all happen client-side, and the file never leaves your machine.
Signing goes further than the usual squiggle. You can draw, type, or upload a visual signature, and then the Kinode Signing Authority embeds a cryptographic X.509 digital signature (PKCS#7) that proves who signed and when. Verification takes one click: drop in any signed PDF and see whether the bytes are intact, who signed, and at what moment. Change one character of a signed file and verification fails.
Capabilities
Every tool, zero uploads
Text overlays, freehand drawing, highlights, shapes, images, and whiteout. Editing happens entirely in your browser, so your documents never touch a server.
Page surgery
Rotate, reorder, and delete pages. Merge documents together or split one apart, all without leaving the browser.
Signatures, three ways
Draw a signature, type one, or upload an image, then place it anywhere on any page.
Real digital signatures
The Kinode Signing Authority embeds cryptographic X.509 signatures with PKCS#7, the same standard Adobe uses. Tamper-evident proof of who signed and when.
One-click verification
Drop in any signed PDF and get an instant verdict: intact or altered, signed by whom, at what moment.
A CA you can install
Download the Kinode CA certificate once and every document you certify validates cleanly across your organization.
