How it works

A screenshot, assembled into pages

Renders in a sandbox
Your HTML loads in an isolated iframe so styles apply normally but scripts never execute.
Captured locally
The rendered page is captured as an image on your device — never sent to a server.
Split into A4 pages
Tall content is automatically paginated across as many pages as it needs.
FAQ

Common questions

No. The HTML is rendered in a sandboxed iframe in your own browser, captured as an image locally, and assembled into a PDF locally — nothing you paste or upload ever leaves your device.
