HTML represents structured web document content with elements and attributes.
PDF preserves a fixed page layout across devices and operating systems.
Chromium prints the uploaded HTML with configurable paper, orientation, margins, and background graphics.
JavaScript is disabled. Network, file, frame, media, font, and object requests are blocked, so only inline styles and data images can affect the output.
Choose A4, US Letter, or US Legal paper, portrait or landscape orientation, background graphics, and margins from 0 to 50 millimeters.
One HTML document up to 5 MB is processed per request. The input limit is 5 MB.
The web application validates the file before forwarding it to a private worker. The worker validates the signature again, processes the file inside a unique temporary directory, validates the output, and removes the job directory in a guaranteed cleanup path. Files are not written to the database or retained for analytics.
When you import from a URL, the application fetches only a validated public HTTP or HTTPS address, checks the downloaded file in memory, and applies the same worker cleanup rules. The URL, filename, and file contents are not sent to analytics.
