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.

Questions & Answers

As answered by people managing DocRaptor and UnitDocs.

What makes your product unique?

UnitDocs's answer:

UnitDocs has a Tenant Timeline — a feature no other landlord tool offers. It gives you a single chronological feed of every event across all your units: rent payments, repairs, move-ins, move-outs, and inspections. When a tenant disputes something or the CRA/IRS audits you, you can find exactly what happened in seconds, not hours.

Unlike full-featured property management platforms, UnitDocs deliberately does one thing really well: keeping all your rental records organized and instantly searchable. No bloat, no complexity — just your docs, expenses, and tenant history, always at your fingertips.

Why should a person choose your product over its competitors?

UnitDocs's answer:

Most competitors are built for professional property managers with 50+ units, and come loaded with rent collection, tenant screening, accounting, and maintenance ticketing. That's a lot of complexity for a DIY landlord with a few units.

UnitDocs is built for a different use case: staying organized. If you're tired of hunting through Gmail for a lease, digging through your phone for a repair photo, or scrambling at tax time for receipts — UnitDocs solves exactly that.

  • Simpler: No learning curve, no setup complexity
  • Cheaper: Free for up to 3 leases, $9.99/month for up to 50
  • Focused: Does one thing really well instead of many things poorly
  • Tenant Timeline: No competitor offers a chronological event history per unit
  • Free forever plan: Genuinely free, no credit card required

How would you describe the primary audience of your product?

UnitDocs's answer:

UnitDocs is built for DIY landlords — individuals who self-manage a small number of rental properties (up to 50 units) without a property management company.

Typically: - Individual landlords with 1–10 rental units - Small-scale real estate investors managing their own properties - Landlords in Canada and the US who need to stay organized for tax season (CRA/IRS) - People who currently manage documents through email, Google Drive, phone photos, or a shoebox - Anyone who wants a simple, affordable alternative to bloated property management software

What's the story behind your product?

UnitDocs's answer:

UnitDocs was born out of a frustration that every DIY landlord knows well: your rental documents are scattered everywhere — leases buried in email, receipts on your phone, inspection notes in a random folder, and repair invoices somewhere in a shoebox.

When a tenant dispute arose or tax season hit, finding the right document was a stressful, time-consuming hunt. Property management platforms existed, but they were designed for professional managers with large portfolios — bloated, expensive, and overkill for a small landlord.

So UnitDocs was built: a focused, simple tool that puts your docs, expenses, and tenant history in one place. The goal was never to build another all-in-one platform. It was to solve one problem really well — organization — for the millions of landlords who just need to stop losing things.

Which are the primary technologies used for building your product?

UnitDocs's answer:

UnitDocs is a web-based SaaS application built on modern, enterprise-grade infrastructure:

  • Authentication: Auth0 (enterprise-grade authentication)
  • Cloud Hosting: Enterprise cloud infrastructure
  • Security: 256-bit encryption in transit and at rest
  • Email: Resend
  • Frontend: Modern web technologies (React-based)
  • Storage: Secure cloud file storage for documents, photos, and videos

Who are some of the biggest customers of your product?

UnitDocs's answer:

UnitDocs serves individual DIY landlords, not large enterprises. Our customers are self-managing landlords in Canada and the US with portfolios ranging from 1 to 50 units.

Some of our users include: - Individual landlords in Toronto, ON and New York, NY managing small multi-unit properties - Small-scale real estate investors who self-manage their rental portfolio - First-time landlords looking for a simple, organized way to manage their documents and expenses

    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!

    I'd argue our service, DocRaptor, is the best because it's the only one powered by the Prince PDF engine.
