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 Diffract.

What makes your product unique?

Diffract's answer:

Diffract is a purpose-built desktop diff tool that handles far more than plain text. A single app compares text, binary (hex view), images, PDFs, Word documents, Excel spreadsheets, ZIP/tar archives, and Git commits - all in a multi-tab interface. On top of the standard Myers diff, it offers Patience and Histogram algorithms per comparison, AST-based semantic diff that understands code structure (not just line changes), and automatic moved-block detection. It also runs fully headless as a CLI tool for use in CI pipelines.

Why should a person choose your product over its competitors?

Diffract's answer:

Diffract is purpose-built, so it supports file types (PDF, Word, Excel, archives), workflows (three-way merge, Git browsing, semantic diff), and UX features (drag-and-drop, OS context menus, in-panel editing with undo/redo, minimap, search) that e.g. an IDE's diff panel simply doesn't cover.

How would you describe the primary audience of your product?

Diffract's answer:

Software developers and DevOps/SRE engineers who compare code, config files, and build artifacts daily. A secondary audience includes QA and release engineers who need to diff generated outputs and directory trees, and technical writers or analysts who compare Word documents, PDFs, or Excel exports without wanting a cloud-based or subscription tool.

Which are the primary technologies used for building your product?

Diffract's answer:

Flutter and Dart (cross-platform desktop UI, targeting Windows, macOS, and Linux).

  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?
