Everything you need for PDF generation

From simple HTML-to-PDF conversion to complex template-based document creation with barcodes, images, and custom fonts.

HTML to PDF

Send raw HTML and receive a perfectly rendered PDF. Full CSS support including Flexbox, Grid, and custom fonts via a headless Chromium engine.

URL to PDF

Point to any URL and get a PDF snapshot. Supports custom viewports, page sizes, landscape mode, and print-optimized rendering.

File Merging

Merge multiple files — PDF, DOCX, XLSX, PPTX, ODT, HTML, images, and emails — into a single unified PDF document.

Template Engine

Create PDFs from templates with positioned text, images, barcodes (Code 128), custom fonts, rotation, and multi-page layouts.

Form Filling

Fill AcroForm PDF fields programmatically. Map data to form fields, insert images, and batch-process multiple documents at once.

REST API

Clean, well-documented REST endpoints with Swagger/OpenAPI specs. Simple JSON request/response format with base64 or buffer output.
