"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."

Got questions? We've got answers.
Learn about our PDF generation API – template features, free plan, and data privacy.
Is there a free plan?
Are failed requests charged?
How are document conversions counted?
- It's simple! On our Free plan, you can generate PDFs up to 2MB in size, with each conversion counting as 1 document.
- On Paid plans, you enjoy unlimited PDF file sizes – convert documents of any size, where each 5MB portion counts as 1 document.
- For example, a 7MB PDF uses 2 documents, and a 12MB PDF uses 3 documents from your monthly usage.
- For each conversion, we return an x-pdfbolt-conversion-cost response header showing exactly how many documents were counted for that particular conversion.
Can I customize the PDF output?
How do you handle data privacy?
- Template data is not stored – it's only used for PDF generation and immediately discarded.
- Your documents are processed on EU-based servers and we are fully GDPR compliant.
- By default, we do not collect sensitive parameters from requests. You can configure which parameters to redact for added privacy.
- Save files to your S3-compatible storage for added security. If you use our storage, documents are deleted after 24 hours.
- For more details, see our Privacy Policy and DPA.
Does PDFBolt store my credit card details?
What are PDF Templates and how do they work?
- Templates let you create reusable PDF layouts that separate design from data. Instead of sending complete HTML for each PDF, you design a template once using Handlebars syntax, then send only your template ID and JSON data to generate personalized PDFs.
- Choose from our professional Templates Gallery of ready-made templates, create custom designs in our visual designer, or generate templates with AI from a simple prompt or reference files.
- Learn more in our Templates Documentation.
