LightningPDF vs LightPDF: Two Different Products, One Confusing Letter

Search for our name and you will likely also find LightPDF. The two products share most of a name and nothing else. This short page exists so you can tell in ten seconds which one you need.

The short version

LightningPDF (this site, lightningpdf.dev) is a developer product: a REST API and MCP server that turns HTML, CSS, Markdown, and templates into PDFs. You integrate it into your application, your billing system, or your AI agent. Nobody edits a document by hand here.

LightPDF (lightpdf.com) is an end-user product: a browser-based PDF editor and converter with OCR. You open a PDF in it and edit, annotate, or convert that one document. It also sells a conversion API, but its center of gravity is the editor.

You want LightningPDF if

• You are a developer generating PDFs programmatically: invoices, reports, certificates, delivery notes
• You need HTML and CSS rendered faithfully, including Tailwind, at API speed
• You want an AI agent (Claude, Cursor, or any MCP client) to produce PDFs through a hosted MCP server
• You need compliant e-invoices: Peppol BIS 3.0, ZUGFeRD/Factur-X, ZATCA, or India GST, with the structured XML leg
• You want post-processing as endpoints: merge, split, compress, protect, PDF/A

You want LightPDF if

• You have a PDF on your desktop and want to edit, annotate, or sign it
• You need OCR on a scanned document
• You want a point-and-click converter between PDF and Office formats
