Uniquely Powerful PDF Generation

Only DocRaptor's HTML-to-PDF API has these advanced styling and layout capabilities:

Easy Headers & Footers

Instead of a separate HTML file, DocRaptor headers and footers are part of your document HTML. And easily show (or hide) different headers and footers for different pages.

Mixed Layout, Sizes & Headers

DocRaptor lets you control the style, sizing, headers, and layouts of individual pages in your document. You can even style left and right pages differently, or the first and last pages.

CSS Flexbox

DocRaptor lets you make PDFs with advanced CSS layout tools, including flexbox. You won't need to radically adjust your website to get a great PDF.

Accessible, Tagged PDFs

Create more accessible PDFs by using PDF profiles PDF/A-1a, PDF/A-3a, or PDF/UA-1. Tagged PDFs optimize the reading experience for assistive technology such as screen readers.

Fine-Tune Page Breaks

Our rendering engine was built specifically for making PDFs and we fully support CSS3 Paged Media. This allows much greater control over page breaks, especially when dealing with tables and images.

โ€ฆand more!

Add crop marks, specify PDF bookmarks, or create standards-compliant documents.

Unmatched Scale & Reliability

We back our API with a 99.999% uptime guarantee. If you need reliability, DocRaptor is the service you can trust. We also have no limits on document input or output size.

Questions & Answers

As answered by people managing DocRaptor and DevToolKit.site.

Why should a person choose your product over its competitors?

DevToolKit.site's answer:

DevToolKit runs 100% in the browser with zero signup. Unlike CyberChef, which has a steep learning curve with its recipe-based interface, DevToolKit gives you 19 standalone tools โ€” each with a clean, focused UI for a single task. Unlike DevToys, it works on any device with a browser โ€” no desktop app installation needed. And unlike SmallDevTools or similar online toolkits, DevToolKit includes unique tools like a PostgreSQL Config Generator (a free PGTune alternative), a Cron Expression Parser that calculates next 10 actual run times, and a JSON Tree Viewer with click-to-copy node paths. Every tool uses native browser APIs like Web Crypto for hashing โ€” no data is ever sent to a server, which matters if you're working with production JWTs, API keys, or database configs.

How would you describe the primary audience of your product?

DevToolKit.site's answer:

Backend and full-stack developers who deal with JSON, JWTs, SQL, cron jobs, and PostgreSQL configuration on a daily basis. DevOps engineers who need quick encoding, hashing, or regex testing without installing CLI tools. Developers who care about data privacy and don't want to paste production tokens or API responses into random websites that may log input data.

What's the story behind your product?

DevToolKit.site's answer:

I'm a backend developer with 10+ years of experience in Python and Go, working on distributed systems and microservices. Every day I was jumping between 5-6 different sites to format JSON, decode a JWT, test a regex, or convert a timestamp โ€” each one bloated with ads, cookie banners, and signup walls. One evening I decided to build all the tools I actually use into a single place where everything runs client-side. The first version had 15 tools and took a weekend to build with Next.js and Tailwind CSS. After getting feedback, I added a PostgreSQL Config Generator (because PGTune hasn't been updated in years), a JSON Tree Viewer, and an HTTP Status Code Reference. It's now at 19 tools and growing based on what developers ask for.

Which are the primary technologies used for building your product?

DevToolKit.site's answer:

Next.js 14 with App Router for server-side rendering and per-page SEO metadata. Tailwind CSS for styling with a custom dark theme. Web Crypto API (crypto.subtle) for SHA-1/256/384/512 hashing and cryptographically secure password generation โ€” zero external crypto libraries. FileReader API for client-side Base64 file encoding. All tools are React components with no backend โ€” the entire app is static and deployed on Vercel. Each tool is a separate route with its own metadata, canonical URL, and sitemap entry for independent Google indexing.

Who are some of the biggest customers of your product?

DevToolKit.site's answer:

DevToolKit is a free tool with no accounts, so we don't track individual users. It's used by individual developers and small teams who need quick, private access to common dev utilities without enterprise overhead. The tool is designed for anyone who works with APIs, databases, or web development and wants a fast, ad-free, privacy-respecting alternative to existing online tools.

What makes your product unique?

DevToolKit.site's answer:

Three things set DevToolKit apart. First, it includes tools you won't find in other online toolkits โ€” a PostgreSQL Config Generator that replaces PGTune with hardware-aware tuning calculations, a Cron Expression Parser that doesn't just describe the schedule but calculates the next 10 actual execution timestamps, and a JSON Tree Viewer where you click any node to copy its full JavaScript path like data.users[0].email. Second, every tool uses native browser APIs instead of external libraries โ€” hashing runs through Web Crypto API with hardware acceleration, passwords use crypto.getRandomValues(), file encoding uses FileReader โ€” meaning zero dependencies and zero data transmission. Third, each of the 19 tools lives on its own URL with dedicated SEO metadata, so you can bookmark devtoolkit.site/jwt-decoder/ and go straight to it โ€” no navigating through menus or loading tools you don't need.

DocRaptor Reviews

  1. Cool app

    I've been using it for a while. It's great to create contracts.

    Great app - resolves the limitations of other doc/merge apps

    We wanted an app that would allow for custom branding and layout, the font of our choice, and merge fields across our main SF objects. Previously we used DocGen, which led to a morass of configuration to put fields in exactly the place they needed to be for the tables, as well as a bunch of SOQL queries to manage conditional logic. The VF doc generator can't accommodate the fonts we use in our branding. And so DocRaptor has been the perfect solution.

    Our developer built the contracts, and we went live within weeks with complete branding, flexibility in the data merges (we were able to remove a ton of bad config) and it's easy to manage.

    ๐Ÿ‘ Pros:    Flexible|Great customer support|Super fast

    The best HTML to PDF solution

    I have been using DocRaptor for 6 years, both for my professionnal and personnal projects. After trying several free and/or open source HTML to PDF solutions, I was happy to find this service. It's the most efficient solution, which generates the most accurate PDF documents.

    Since it's a SaaS service, there is nothing to install, no library dependencies nor experimental software that you're not sure it will be supported in the future.

    There is a lot of options and CSS rules to dig in if you want to get PDF files that exactly matches what you want. But the other solutions I tried didn't have these options, and the result was not good enough.

    ๐Ÿ Competitors: pdfmatrix.com, SelectPdf, pdflayer, Api2Pdf, PDFCrowd
    ๐Ÿ‘ Pros:    Simple api|No dependencies|Best pdf result|A lot of options to help you create the pdf you need|Good customer support
    ๐Ÿ‘Ž Cons:    A lot of css rules to learn if you want to get the perfect pdf of your dreams... but at least these rules exist!

  • Launch HN: Onedoc (YC W24) โ€“ A better way to create PDFs
    It sounds like this is as advanced as DocRaptor[1]. They have what I consider to be the best PDF generation API, giving complete control over the documents you need to create. The pricing is similar. If you'd rather do it for free weasyprint[2] is the best open source alternative. Another more affordable option you might want to consider is Urlbox[3].

  • How do you generate PDF reports from HTML?
    We built the DocRaptor API to let developers have affordable access to the commercial Prince PDF engine. We have Node code examples throughout the documentation. Source: almost 4 years ago
  • What is the best online HTML to PDF converter?
    I'd argue our service, DocRaptor, is the best because it's the only one powered by the Prince PDF engine. Unlike open-source, browser-based conversion engines, Prince was custom-built just for converting HTML into PDFs and offers a lot of unique functionality for making more complex PDFs.

  • Is it possible to render a RazorPage (inc. CSS) to a PDF file and download via WebAPI?
