Verifiable documents · Editor + API · Beta

Generate documents.
Prove they're real.

Design visually or generate by API. Every PDF is sealed — so anyone can verify it’s authentic, no login.

No credit card. 500 documents/month free in beta.

The problem

Anyone can fake a PDF.

A logo, a total, a signature — copied in seconds. Invoices, certificates, contracts: whoever receives yours has no real way to know it’s genuine. So a “document” proves nothing.

Verifiable by anyone

Every document proves itself.

Each PDF is sealed with a SHA-256 fingerprint and a QR. Drop it at /verify and it confirms — in a second, no account — who issued it and that not a byte changed.

  • Tamper-evident — change one pixel and verification fails
  • Public check — your client verifies without logging in
  • Provenance on record — issuer, template and timestamp
  • The proof is a QR, right on the document

Design without code

A visual editor that speaks API.

Drag blocks to build any document. Mark the dynamic parts with {{variables}} — then generate thousands by API.

  • Figma-style drag-and-drop
  • Tables, charts, QR, signatures
  • {{variables}} bind to your JSON
  • What you design is what ships
Renderly visual editor
How it works

Three steps from editor to API.

  1. 01

    Design in the editor

    Build an invoice, receipt or certificate by dragging blocks. Mark dynamic fields with {{variables}}.

  2. 02

    Send the data

    A POST to /v1/render with your JSON. No browser or render server to maintain.

  3. 03

    Get a sealed PDF

    Back in the response — sealed and verifiable, with a QR that checks out at /verify.

POST /v1/render
curl -X POST https://api.renderly.dev/v1/render \
  -H "Authorization: Bearer rndr_live_..." \
  -H "Content-Type: application/json" \
  -d '{ "template": "invoice", "data": { "client": "Acme", "total": "$1,480.00" } }' \
  --output invoice.pdf

Built to be trusted

Security isn’t a feature here. It’s the foundation.

Cryptographic integrity

Every document is SHA-256 sealed on issue. Verification is math, not trust.

Tenant isolation

Your templates and data are scoped to your org — no cross-tenant leaks, by design.

Deterministic engine

Same document, same bytes, same hash, every time. That’s what makes the proof reliable.

We don’t keep your PDFs

Documents are generated and handed back. We store the fingerprint to verify — not your content.

And yes — it’s fast

A native engine. No headless browser.

Most PDF APIs boot a whole browser per request. Renderly draws documents directly — milliseconds, deterministic, cheap to scale. Fast is nice. Verifiable is the point.
