Browser Automation Platform
Browserless
Browserless provides headless browser APIs for automation through a managed cloud service or a self-hosted Docker deployment. Developers can connect Puppeteer or Playwright over WebSocket, use Selenium, or call BrowserQL and REST APIs for scraping, screenshots, and PDFs. Its REST /pdf endpoint accepts either a URL or raw HTML and returns a binary PDF without requiring a browser library in your application. This comparison focuses specifically on the Browserless PDF API.
PDF Generation API
PDFBolt
PDFBolt is a managed Chromium PDF generation API for repeatable document workflows. It converts HTTPS URLs, Base64-encoded HTML, and published Handlebars templates with JSON data. AI can generate templates from prompts or reference files. Direct returns PDF data, Sync provides a temporary URL, and Async returns a request ID before sending a signed completion webhook. PDFBolt also supports S3‑compatible delivery, four compression levels, and PDF/X output with CMYK conversion and ICC profiles.

When PDFBolt Is the Better Fit
for PDF Generation
Managed templates, flexible delivery, compression, and print-ready output are built into PDFBolt.
Manage reusable templates from code
Use the Template API to create, validate, preview, compare, save, and publish reusable templates without opening the Dashboard Template Designer.
Design templates with live preview and AI
Start with a gallery layout, edit it with live preview, or use AI to create a first draft from a prompt and reference files.
Choose how each PDF is delivered
Use Direct for PDF bytes, Sync for a temporary download URL, or Async for background generation. Browserless's documented /pdf endpoint returns the file directly in the HTTP response.
Verify Async callbacks
PDFBolt signs every Async webhook with HMAC-SHA256. Configure retries for failed conversion attempts, then receive one callback when the conversion succeeds or all retries fail.
Compress PDFs as they are generated
Apply lossless, low, medium, or high compression while each PDF is generated. Browserless's PDF endpoint does not document a configurable compression option.
Generate print-ready PDFs
Generate PDF/X-1a or PDF/X-4 with RGB-to-CMYK conversion and FOGRA39, FOGRA51, SWOP, or GRACoL ICC profiles.
Browserless vs PDFBolt: A Closer Look
How the two platforms handle reusable document layouts, developer workflows, and PDF output.
Managing Reusable Document Layouts
Browserless
Browserless renders a URL or raw HTML and lets each request configure navigation, waits, authentication, cookies, headers, scripts, and styles. This works well when the application already owns the page or HTML. Reusable layouts stay in the application, which supplies the current URL or HTML for each render.
PDFBolt
PDFBolt stores reusable Handlebars templates and combines the published version with templateData for each API conversion. The Template Designer supports drafts, PDF previews, published versions, version history, and restoring an earlier version as a new draft. A template can start from scratch, from the template gallery, or from AI generation based on a prompt and reference files.
Developer Experience
Browserless
Browserless's stateless /pdf endpoint accepts a URL or raw HTML and returns a binary PDF in the same HTTP response. Its guides and OpenAPI reference include examples for cURL, JavaScript/Node.js, Python, Java, C#, PHP, Go, and Ruby. The OpenAPI-based REST API Playground lets you configure and run requests, inspect responses, and copy cURL commands. For more control over the browser, developers can use BrowserQL or connect with Puppeteer or Playwright.
PDFBolt
PDFBolt provides official SDKs for Node.js, Python, and PHP. REST Quick Starts cover Node.js, Python, PHP, Java, C#, Go, and Rust, with cURL examples and a Postman collection. The Template API lets applications, CI workflows, and AI coding agents such as Codex and Claude Code manage reusable templates programmatically. The Playground lets you configure and preview URL, HTML, or template conversions, then copy API code for the selected settings. PDFBolt also provides a verified n8n Community Node and integration guides for Make, Zapier, and other automation platforms. Direct returns PDF bytes, Sync returns a temporary URL, and Async returns an immediate request ID followed by a signed completion webhook. Sync and Async can upload directly to an S3-compatible bucket through a presigned URL.
PDF-Specific Features
Browserless
Browserless's /pdf endpoint supports PDF options based on Puppeteer's interface, including standard and custom page sizes, margins, landscape orientation, page ranges, background graphics, HTML header and footer templates, tagged PDFs, and document outlines.
PDFBolt
PDFBolt also supports standard page formats, custom dimensions, margins, orientation, HTML headers and footers, and background printing. It supports tagged PDFs and applies lossless, low, medium, or high compression as part of PDF generation. For commercial print, it can produce PDF/X-1a or PDF/X-4 output, convert RGB content to CMYK, and use FOGRA39, FOGRA51, SWOP, or GRACoL ICC profiles. Tagged output adds document structure but does not by itself guarantee PDF/UA conformance.
How to Migrate from Browserless to PDFBolt
Replace simple Browserless /pdf calls with PDFBolt Direct using a few API changes.
Browserless REST /pdf
import fs from 'fs';
const response = await fetch(
'https://production-sfo.browserless.io/pdf?token=YOUR_TOKEN',
{
method: 'POST',
headers: {
'Cache-Control': 'no-cache',
'Content-Type': 'application/json',
},
body: JSON.stringify({
url: 'https://example.com',
options: {
printBackground: true,
format: 'A4',
},
}),
}
);
const buffer = await response.arrayBuffer();
fs.writeFileSync('output.pdf', Buffer.from(buffer));
PDFBolt
const fs = require('fs');
async function generatePdf() {
const response = await fetch('https://api.pdfbolt.com/v1/direct', {
method: 'POST',
headers: {
'API-KEY': 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX',
'Content-Type': 'application/json'
},
body: JSON.stringify({
url: 'https://example.com',
format: 'A4',
printBackground: true
})
});
if (!response.ok) {
const errorText = await response.text();
throw new Error(`HTTP ${response.status} - ${errorText}`);
}
const pdfBuffer = await response.arrayBuffer();
fs.writeFileSync('webpage.pdf', Buffer.from(pdfBuffer));
}
generatePdf().catch(console.error);

What Developers Say About PDFBolt
See how teams save time and reduce complexity with our developer‑first PDF solution.
"It has a very intuitive User Interface and easy to use API with a great documentation. What's best, that the support is super fast and even feature requests are discussed and implemented in just a couple of days. It helps us to create individualised PDF gift cards both for digital use as well as print production on the base of modern HTML / CSS."
"Amazingly, the owner personally helped solve the issues I was having creating an exported lesson plan with hyperlinks and complex styling. This is a great piece of software. But more importantly, it’s the people behind a product that truly make a company great. His willingness to support my project without payment is truly unique – a rare product and a rare individual. This product just works. Thank you, PDFBolt!"
"There's a lot of products that convert to PDF out there, but this one stood out to me, because the output quality is good, it's very easy to use, and pay per use. I also love the interactive API documentation, my request just worked out of the box in my app. And of course the focus on privacy, which is important when working with GDPR data. (...) PDFBolt just works, so I can focus on the business logic."
