Honest comparison

Why Majorsilence.Pdf?

There is no shortage of PDF libraries for .NET. Here is a clear-eyed look at where Majorsilence.Pdf fits, where it excels, and when you should reach for something else instead.

Library comparison

The table below covers the most commonly reached-for .NET PDF libraries. All information is based on publicly available documentation as of mid-2026.

Library License Dependencies Package size API model .NET support
Majorsilence.Pdf MIT / Apache / BSD Zero ~75 KB Canvas / fluent NS2.0, .NET 8 & 10
iText 7 AGPL or commercial Several NuGet refs ~6 MB Document/element tree .NET Standard 2.0+
QuestPDF Community / commercial SkiaSharp (native) ~10 MB (incl. native) Fluent layout engine .NET 6+
PdfSharp MIT None (for core) ~400 KB GDI-style drawing .NET 6+ (v0.1.x NS2.0)
Syncfusion PDF Commercial / community Syncfusion suite ~4 MB Document/element tree .NET Standard 2.0+
Puppeteer / wkhtmltopdf MIT (Puppeteer) Native binary required 50–150 MB (browser) HTML → PDF render Any (via CLI/bridge)

The "Community" tier of QuestPDF is free for organisations with annual revenue under $1 M USD; above that, a paid license is required. iText 7 requires a commercial license for closed-source software. Syncfusion has a free community licence for individual developers and small teams.

When to choose Majorsilence.Pdf

Good fit
  • Zero runtime dependencies is a hard requirement — containers, AWS Lambda, AOT compilation, or strict security audits
  • You need MIT, Apache-2.0, or BSD-3-Clause licensing with no AGPL complications
  • You want a small, auditable codebase with no native binaries to manage
  • Your mental model is canvas-coordinate drawing — place text at (x, y), draw lines, embed images
  • You're building invoices, reports, certificates, receipts, or data exports where you control the layout
  • Trim-friendliness or AOT compilation matters (serverless cold starts, embedded .NET)
  • You want to ship to Windows, Linux, and macOS without worrying about native font rendering libraries
Less ideal fit
  • You need to read, edit, or merge complex existing PDFs with annotations, AcroForms, or XFA
  • PDF/A or PDF/UA compliance certification is required by a regulatory body
  • You prefer a flow-based layout model (paragraphs that wrap automatically, tables that paginate) over explicit coordinates
  • You need production-grade Arabic shaping or complex BiDi text rendering
  • Your content already lives in HTML/CSS templates and pixel-perfect browser rendering is essential
  • You need advanced timestamped digital signatures (PKCS#12 with TSA) or long-term validation (PAdES LTV)

When to reach for something else

These are honest recommendations. Pick the right tool for your constraints.

iText 7
If you need the most complete PDF feature set available in .NET — AcroForm manipulation, PAdES/LTV digital signatures, PDF/A and PDF/UA creation, redaction, or reading and modifying complex existing PDFs — and you can use the AGPL license or purchase a commercial one.
QuestPDF
If you prefer thinking in terms of rows, columns, and flowing content (a layout engine rather than a drawing canvas), and your revenue is below the community tier threshold. QuestPDF's fluent document model is excellent for rich, content-heavy documents where automatic pagination matters more than pixel-precise placement.
PdfSharp
If you want another zero-dependency MIT library with a GDI-style drawing API and are targeting .NET 6+. PdfSharp is a solid alternative with a larger community and longer history. The two libraries have similar strengths; evaluate the API style to see which fits your team better.
Puppeteer / Playwright / wkhtmltopdf
If your document content is already authored as HTML + CSS — e.g. a templated invoice rendered by a Razor view — and you need pixel-perfect browser-engine rendering (web fonts, CSS grid, background images). The trade-off is a large native binary dependency and slower generation times.
Syncfusion / DevExpress / Telerik
If you are already licensed for one of these component suites and want a single vendor for all your UI and document-generation needs. The PDF libraries bundled in these suites are full-featured and well-supported within their ecosystems.

Design philosophy

Most PDF libraries grew up when .NET meant Windows, NuGet was young, and "zero dependencies" was not a design goal. They accumulated features, native code, and license complexity over time.

Majorsilence.Pdf starts from different constraints:

Production-proven. Majorsilence.Pdf is the PDF rendering engine that powers Majorsilence Reporting. It is not a side project — it is the library that runs when Reporting generates real documents.

Make the boring simple.

Generating a PDF — an invoice, a certificate, a data export — should take a handful of lines, not a page of boilerplate. The library surface is intentionally small: a document, pages, a canvas. You place things. You save. Done.

Zero should mean zero.

Not "zero at runtime if you install the platform pack" or "zero unless you use fonts." One dotnet add package and nothing else. No transitive tree to audit, no native binaries to include in your container image, no AGPL risk to review with legal.

Pure managed code.

The whole library is IL. It trims cleanly, compiles ahead-of-time, and runs the same on Windows, Linux, macOS, ARM, and x64 — without conditional native asset selection or runtime feature detection.

Tri-licensed. Pick whichever of MIT, Apache-2.0, or BSD-3-Clause suits your project. There is no AGPL tier, no community-vs-commercial split, and no revenue threshold that changes your obligations.
