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.

…and 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.

ExpressJS features and specs

  • Fast Setup
    ExpressJS provides a minimal and flexible framework that allows rapid setup and development of web and mobile applications.
  • Middleware Support
    ExpressJS has a robust middleware system, allowing developers to add reusable functions to the request-handling pipeline.
  • Extensibility
    ExpressJS is highly extensible through third-party libraries and built-in functionality, catering to the needs of various applications.
  • Performance
    Due to its minimalist core, ExpressJS provides efficient performance and is capable of handling a high number of requests per second.
  • Community and Ecosystem
    A large and active community provides extensive documentation, support, and a wide array of open-source packages to extend functionality.
  • Flexibility
    Compared to full-stack frameworks, ExpressJS gives developers the freedom to structure their applications as they see fit.
  • Compatibility
    ExpressJS works seamlessly with various template engines, databases, and other frameworks, making it versatile for different project requirements.

Possible disadvantages of ExpressJS

  • Minimalist Core
    The minimalist nature of ExpressJS may require additional time and effort to integrate required plugins and libraries for specific features.
  • Learning Curve
    While ExpressJS is straightforward, mastering the middleware pattern and effective usage can have a learning curve for new developers.
  • Callback Hell
    Developers can encounter 'callback hell' due to nested callback functions, though this can be mitigated using Promises and async/await in modern JavaScript.
  • Lack of Convention
    Unlike opinionated frameworks, ExpressJS lacks conventions, which can lead to inconsistent code structure and maintenance challenges across different projects.
  • Security
    ExpressJS does not have built-in security features and relies on third-party solutions, requiring developers to be vigilant about applying best security practices.
  • Scalability
    While ExpressJS can handle high traffic, building and maintaining a highly scalable application might require significant additional effort, particularly in terms of codebase organization and resource management.

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.

    👍 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.

    👍 Pros:    Simple api|No dependencies|Best pdf result|A lot of options to help you create the pdf you need|Good customer support
    👎 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!
