ShreePdf

Radiant, intelligent PDF generation for .NET — built for the AI era.

Generate beautifully designed PDFs directly from C#, Markdown, or HTML — no headless browser, no native print stack, no external services.

Install

dotnet add package ShreePdf

Hello, PDF

using ShreePdf.Fluent;

Document.Create("Welcome")
    .AddText("Hello, ShreePdf 👋", fontSize: 24, isBold: true)
    .AddText("Beautiful, themed PDFs — straight from C#.")
    .Save("welcome.pdf");

Markdown & LLM output → themed PDF

Perfect for turning AI assistant responses or docs into polished output.

string markdown = """
# Quarterly Review
- Revenue up **24%**
- Churn down **3%**

> Prepared by our AI assistant.
""";

Document.FromMarkdown(markdown, ThemePresets.SaaSAnalytics)
    .EnableAutoFit()
    .Save("review.pdf");

Ingestion understands inline images — Markdown ![alt](src) and HTML <img>, resolved from a file path, URL, or data URI — and Markdown links ([text](url)). A broken image source is skipped rather than failing the whole document.

Rich documents with the fluent API

var pdf = Document.Create("Invoice #1042")
    .WithTheme(ThemePresets.ExecutiveMinimal)
    .AddImageFromFile("logo.png", width: 120)
    .AddText("Invoice #1042", fontSize: 20, isBold: true)
    .AddBulletList("Design services", "Cloud hosting", "Priority support")
    .AddTable(t =>
    {
        t.Columns.Add(new TableColumn { Header = "Item" });
        t.Columns.Add(new TableColumn { Header = "Amount", Alignment = Alignment.Right });

        var row = new TableRow();
        row.Cells.Add("Total due");
        row.Cells.Add(new TableCell("$4,200.00") { IsBold = true, Alignment = Alignment.Right });
        t.Rows.Add(row);
    })
    .AddPageNumber("Page {page} of {pages}")
    .GenerateBytes();

Native charts, KPIs & barcodes

Embed native vector visuals, metric cards, barcodes, and multi-column text with single-line fluent helpers.

Document.Create("Executive Dashboard")
    .WithTheme(ThemePresets.SaaSAnalytics)
    // KPI Stat Cards & Status Badges
    .AddStatCards(
        new StatCard("Revenue", "$1.24M", "+14.2%", deltaPositive: true),
        new StatCard("Active Users", "42.5K", "+8.1%", deltaPositive: true),
        new StatCard("Churn Rate", "1.2%", "-0.4%", deltaPositive: true))
    .AddBadge("Target Achieved", BadgeStatus.Success)

    // Vector Charts (Bar, Line, Area, Pie, Donut)
    .AddBarChart("Quarterly Sales", ("Q1", 240), ("Q2", 310), ("Q3", 280), ("Q4", 410))
    .AddPieChart("Traffic Share", ("Direct", 45), ("Search", 35), ("Social", 20))

    // Sparklines & KPI Progress Meters
    .AddSparkline(SparklineType.Line, 12, 18, 15, 22, 28, 34)
    .AddProgressBar("Storage Quota", value: 78, max: 100)

    // Barcodes & QR Codes
    .AddBarcode(BarcodeType.Code128, "INV-2026-9901")
    .AddQrCode("https://example.com/invoice/9901")

    // Multi-Column Text Flow
    .AddMultiColumn("ShreePdf automatically wraps and balances long text across multiple newspaper-style columns.", columns: 2, height: 100)
    .Save("dashboard.pdf");

Navigation: bookmarks & table of contents

Headings automatically become a reader-sidebar bookmark outline, and a one-liner drops in an auto table of contents with page numbers and clickable rows.

Document.Create("Handbook")
    .AddTableOfContents("Contents")     // page numbers + links, filled automatically
    .AddHeading("Getting Started", 1)   // becomes a bookmark + a TOC row
    .AddText("Welcome to the handbook.")
    .AddHeading("Installation", 2)      // nested under the previous heading
    .AddText("Add the NuGet package and you're set.")
    .AddHeading("Advanced Usage", 1)
    .Save("handbook.pdf");

Enterprise security & AES-256 encryption

Protect confidential documents with ISO 32000-1 AES-256 encryption, password controls, permissions, and security watermarks.

using ShreePdf.Fluent;
using ShreePdf.Security;

var doc = Document.Create("Confidential Strategy")
    .WithTheme(ThemePresets.ExecutiveMinimal)
    .AddHeading("Confidential Executive Review", 1)
    .AddText("This document is protected and confidential.");

// Enable AES-256 encryption & permission flags
doc.Security.IsEncryptionEnabled = true;
doc.Security.UserPassword = "UserPassword123";
doc.Security.OwnerPassword = "MasterOwnerKey!";
doc.Security.EncryptionAlgorithm = PdfEncryptionAlgorithm.AES_256Bit;
doc.Security.Permissions = DocumentPermissions.Print | DocumentPermissions.Copy;

// Add dynamic anti-leak security watermark
doc.Security.EnableWatermark = true;
doc.Security.WatermarkText = "CONFIDENTIAL - INTERNAL ONLY";

doc.Save("secured-review.pdf");

PDF manipulation, merging & dynamic stamping (v1.14.0)

using ShreePdf.Manipulation;

// 1. Merge multiple PDF byte streams while preserving & fusing RAG metadata
byte[] mergedPdf = PdfDocumentModifier.MergeDocuments(new[] { doc1Bytes, doc2Bytes });

// 2. Extract specific page ranges or permute page order
byte[] slicePdf = PdfDocumentModifier.ExtractPages(mergedPdf, new[] { 1, 3, 5 });
byte[] reorderedPdf = PdfDocumentModifier.ReorderPages(mergedPdf, new[] { 3, 1, 2 });

// 3. Stamp dynamic watermarks, Bates numbers, and headers/footers
byte[] batesStamped = PdfPageStamper.StampBatesNumber(reorderedPdf, prefix: "ACME-CONF-", startNumber: 1001);
byte[] finalPdf = PdfPageStamper.StampWatermark(batesStamped, "INTERNAL REVIEW ONLY", opacity: 0.25f);

var data = new Dictionary<string, string?> { ["customer"] = "Ada Lovelace", ["total"] = "$4,200" };

Document.FromMarkdownTemplate("# Statement for {{customer}}\n\nBalance: **{{total}}**", data)
    .Save("statement.pdf");

Output anywhere

doc.Save("report.pdf");                    // to a file
byte[] bytes = doc.GenerateBytes();        // in memory
await doc.GenerateBytesAsync();            // async (web / serverless)
doc.GenerateToStream(httpResponseStream);  // stream directly, bounded memory
