Html2PDF Pricing: Detailed Plans and Real-World Examples (2026)

Pricing overview

Html2PDF offers a usage-based pricing model, primarily structured around the number of HTML to PDF conversions performed per month. This approach allows users to scale their costs in alignment with their operational demands. A free tier is available for initial evaluation and low-volume requirements, while various paid plans cater to increasing conversion volumes and offer additional features or support levels. The core service converts HTML, CSS, and JavaScript into PDF documents via an API (Html2PDF API reference), making it suitable for applications requiring automated document generation.

The pricing structure is designed to accommodate a range of users, from individual developers testing the service to enterprises requiring high-volume, programmatic PDF generation for tasks such as invoice creation or report delivery. Understanding the different tiers and their respective limits is crucial for selecting a plan that aligns with an application's anticipated usage pattern and budget constraints (Html2PDF official pricing page).

Plans and tiers

Html2PDF provides several plans that differentiate primarily by the number of included conversions per month and the associated monthly cost. As the volume of conversions increases, the per-conversion cost generally decreases, reflecting a common tiered pricing strategy in API services. Each plan specifies a maximum number of conversions, and exceeding this limit typically incurs additional charges or requires an upgrade to a higher tier.

The plans are typically structured to offer a clear progression for users as their needs evolve, starting from a free option and moving through various paid tiers. These tiers might also include access to specific features, higher priority support, or dedicated resources depending on the provider's specific offerings.

Plan Comparison Table

Plan Name	Monthly Price	Included Conversions	Best For
Free	$0	250	Testing, low-volume personal projects, initial development
Starter	$9	1,000	Small applications, personal websites, early-stage startups
Growth	$29	5,000	Growing applications, small businesses requiring regular document generation
Professional	$99	25,000	Medium-sized businesses, applications with significant automated reporting needs
Enterprise	Custom	Variable (high volume)	Large organizations, high-volume B2B platforms, custom requirements

Free tier and limits

Html2PDF offers a free tier designed for developers to evaluate the service and for projects with minimal PDF generation requirements. This tier includes up to 250 conversions per month at no cost. It provides full access to the core HTML to PDF conversion functionality, allowing users to integrate the API and test its capabilities without financial commitment.

The free tier is suitable for:

Prototyping and development of new applications.
Personal projects or small blogs that occasionally require PDF generation.
Educational purposes or learning how to integrate the Html2PDF API (see the Html2PDF documentation).

While the free tier provides ample scope for initial use, users should monitor their monthly conversion usage. Exceeding the 250-conversion limit within a month will necessitate an upgrade to a paid plan. The free tier typically includes standard support, and it may have certain limitations compared to paid plans, such as rate limits or lower priority for processing requests during peak times, though these specifics would be detailed on the provider's official pricing or terms of service pages.

Real-world cost examples

To illustrate how Html2PDF's pricing translates to real-world scenarios, consider the following examples:

Example 1: Small Business Invoice Generation

A small e-commerce business generates approximately 1,500 invoices per month. Each invoice requires one HTML to PDF conversion. For this scenario, the business would typically require 1,500 conversions per month.

Relevant Plan: The Starter plan includes 1,000 conversions. To cover the additional 500 conversions, the business would either need to upgrade to the Growth plan (5,000 conversions for $29/month) or incur overage charges on the Starter plan, if applicable. Assuming an upgrade to the Growth plan, the monthly cost would be $29.
Annual Cost: $29/month * 12 months = $348 per year.

Example 2: SaaS Platform with Automated Reports

A Software-as-a-Service (SaaS) platform provides monthly performance reports to its 3,000 active customers. Each report is generated as a PDF, totaling 3,000 conversions per month.

Relevant Plan: The Growth plan, offering 5,000 conversions for $29/month, would comfortably cover this usage.
Annual Cost: $29/month * 12 months = $348 per year.

Example 3: Educational Platform with Certification Generation

An online learning platform issues digital certificates to students upon course completion. They anticipate issuing around 20,000 certificates per month during peak periods.

Relevant Plan: The Professional plan, including 25,000 conversions for $99/month, would be suitable for this volume.
Annual Cost: $99/month * 12 months = $1,188 per year.

Example 4: Enterprise-level Document Archiving

A large financial institution needs to convert thousands of historical web pages into PDF for archiving purposes, estimating 100,000 conversions over a single quarter, averaging approximately 33,000 per month.

Relevant Plan: This volume would likely require a custom Enterprise plan due to exceeding the Professional tier's limits significantly. The cost would be negotiated directly with Html2PDF based on specific requirements, potential volume discounts, and support needs. For context, if a hypothetical per-conversion rate was similar to higher tiers (e.g., ~$0.003-$0.004 per conversion), costs could range from $300-$400 per month.

How the pricing compares

The landscape of HTML to PDF conversion services includes both commercial APIs and open-source libraries. Html2PDF's pricing model, based on monthly conversion volume, is a common approach among commercial providers. Comparing its pricing requires consideration of not just the per-conversion cost but also the features, reliability, and ease of integration offered by alternatives.

Commercial API Alternatives

DocRaptor: DocRaptor also offers a tiered pricing model with a free tier and paid plans based on document volume. Its pricing can be competitive, particularly for high-volume users, and it often emphasizes high-quality rendering. For instance, DocRaptor's plans start at similar price points but may offer different tiers for features like PDF/A support or dedicated rendering queues, as detailed on the DocRaptor pricing page.
Other cloud-based PDF APIs: Many cloud providers, such as AWS with Lambda functions for custom PDF generation or Google Cloud with solutions like Cloud Functions and Puppeteer, offer building blocks for PDF generation. While these are not direct API services, their pricing is based on compute time, storage, and egress. The total cost can vary significantly depending on development effort, operational overhead, and the specific architecture chosen. For example, AWS Lambda pricing is based on requests and compute duration (AWS Lambda pricing details).

Open-Source Alternatives

PDFKit: PDFKit is a Node.js PDF generation library. It is free to use but requires self-hosting and development effort for integration and maintenance. The cost associated with PDFKit is primarily in developer time, server resources, and ongoing maintenance. While there's no direct per-conversion fee, infrastructure costs (e.g., Google Compute Engine pricing for hosting) and engineering overhead must be considered.
Gotenberg: Gotenberg is a Docker-powered stateless API for converting HTML, Markdown, and URL to PDF. Similar to PDFKit, it is open-source and free, but requires self-hosting and infrastructure management. The pricing comparison here shifts from a per-conversion fee to the operational costs of maintaining and scaling a server infrastructure capable of handling the conversion load, alongside developer time for setup and custom development.

Html2PDF positions itself as a managed service, offering a balance between the ease of use of a commercial API and competitive pricing for various volume needs. This contrasts with open-source solutions where the upfront monetary cost is zero, but the total cost of ownership (TCO) includes significant operational and development expenses.
