Stop Playing Defense. Eliminate the Attack Surface.

Every vulnerability above was preventable with memory-safe code. OxidPDF isn't just "more secure" – it's architecturally immune to the entire class of vulnerabilities that plague C++ PDF viewers.

See How We Solved It
MEMORY-SAFE ARCHITECTURE

How OxidPDF Works

Three fundamental design decisions that eliminate PDF vulnerabilities at the language level. Not patches, not mitigations – architectural immunity.

1

Built in Rust

Every line of our 126,000+ codebase is written in Rust, a systems programming language that prevents memory corruption at compile time.

// Memory-safe by design
fn
parse_pdf
(data: &[u8]) -> Result<
PDF
,
Error
>
// No buffer overflows possible
// No use-after-free possible
// Compiler guarantees it
2

Memory Safety

Rust's ownership system eliminates entire classes of vulnerabilities. No garbage collector needed, no runtime overhead.

Buffer Overflow ❌ C++
Use-After-Free ❌ C++
Memory Safety ✅ Rust

Zero CVEs

Not a single memory corruption vulnerability is possible. This isn't a promise – it's a mathematical guarantee from the type system.

The Technical Details

Why Rust Eliminates Vulnerabilities

  • Ownership System: Every piece of memory has exactly one owner. No double-free, no memory leaks.
  • Borrowing Rules: References are checked at compile time. No dangling pointers possible.
  • Zero-Cost Abstractions: Memory safety with no runtime overhead.
  • Thread Safety: Data races prevented at compile time.

The Rust Advantage

We didn't just build a better PDF editor. We eliminated entire classes of vulnerabilities that have plagued document processing for decades.

Memory Safety by Design

No Buffer Overflows

Rust's ownership system prevents reading/writing beyond allocated memory bounds — eliminating the #1 cause of PDF vulnerabilities.

No Use-After-Free

Memory is automatically freed when no longer needed. No dangling pointers, no accessing freed memory — entire vulnerability class eliminated.

No JavaScript Execution

PDFs are documents, not applications. We strip all JavaScript, embedded files, and remote actions that turn documents into attack vectors.

vulnerable-pdf-reader.c
// Typical C++ PDF parsing (vulnerable)
char buffer[1024];
strcpy(buffer, user_input); // 🚨 Buffer overflow
PDF_Object* obj = malloc(...);
process(obj);
free(obj); // 🚨 Use after free possible
execute_javascript(pdf); // 🚨 Code execution
oxidpdf.rs
// OxidPDF Rust implementation (secure)
let buffer = Vec::with_capacity(user_input.len());
buffer.extend_from_slice(&user_input); // ✅ Bounds checked
let obj = PdfObject::new(...); // ✅ No manual memory
process(&obj); // ✅ Borrow checker prevents use-after-free
// ✅ No JavaScript execution - stripped by design

Local-First Privacy

Your documents never leave your machine unless you choose to share them. No cloud uploads, no server processing, no privacy compromises.

Questions & Answers

Everything you need to know about OxidPDF's security, performance, and enterprise features. Can't find your answer? Contact us directly.

Security & Privacy

OxidPDF is built entirely in Rust, a memory-safe programming language that prevents buffer overflows, use-after-free, and other memory corruption bugs at compile time. These vulnerabilities account for 70-80% of all CVEs in traditional C++ PDF viewers like Adobe Acrobat. By using Rust, we architecturally eliminate this entire class of security issues.

Additionally, we disable JavaScript execution by default, strip potentially malicious embedded content, and process everything locally on your machine – never uploading documents to cloud servers unless you explicitly choose to share them.

Local-first means your PDFs are processed entirely on your device. When you open, edit, or manipulate a PDF in OxidPDF, the document never leaves your computer unless you explicitly save it elsewhere or share it.

This is different from cloud-based solutions like SmallPDF where your documents are uploaded to remote servers. With OxidPDF, you maintain complete control over your data, making it ideal for regulated industries like healthcare (HIPAA), finance (SOX), and legal (attorney-client privilege).

Yes, absolutely. OxidPDF is designed to work completely offline. All PDF processing, rendering, editing, and security features work without any internet connection. This makes it perfect for:

Government and defense contractors with security clearance requirements
Healthcare systems with strict data isolation policies
Financial institutions in air-gapped trading environments
Any organization that needs to process sensitive documents offline

The only time OxidPDF needs internet is for software updates and optional cloud integrations (if you choose to enable them).

OxidPDF's local-first architecture makes compliance much simpler:

**HIPAA (Healthcare)**: No PHI ever leaves your infrastructure, eliminating most data breach risks and reducing audit scope
**SOX (Financial)**: Complete audit logging of document access and modifications, with local storage preventing unauthorized access
**GDPR (Privacy)**: No personal data transmitted to third parties; users have complete control over their documents
**FedRAMP (Government)**: Air-gap compatibility and security architecture designed for high-security environments

We provide compliance documentation and can work with your legal/compliance team to validate our security model for your specific requirements.

Performance & Technical

Three main reasons:

1. Rust's Zero-Cost Abstractions: Rust compiles to highly optimized machine code without runtime overhead, unlike interpreted languages or garbage-collected languages
2. Modern Architecture: We built OxidPDF from scratch using modern algorithms and data structures, while Adobe Acrobat carries 30+ years of legacy code
3. Local Processing: No network latency or server round-trips – everything happens on your local hardware at maximum speed

Our benchmarks show opening a 1000-page PDF in 2.2ms versus Adobe's ~1,200ms – over 500x faster. These aren't synthetic benchmarks; they're real-world performance measurements.

Our browser version uses the same Rust codebase compiled to WebAssembly (WASM), so you get identical functionality and security in your web browser. Performance is slightly slower than the native desktop app but still significantly faster than server-based solutions.

Key benefits of the WASM version:

No software installation required
Same local-first processing (no uploads)
Works across all modern browsers
Perfect for occasional users or shared computers
Identical security guarantees as the desktop version

Currently in beta with ~85% of desktop performance. We're actively optimizing the WASM build for production release.

OxidPDF supports all major PDF features:

Fully Supported::

PDF viewing and navigation (all versions 1.4-2.0)
Text editing and formatting
13 annotation types with 23 standard stamps
Form fields (creation, editing, persistence)
Digital signatures (PKCS#7/CMS standard)
Document merge, split, and reorder
OCR (Optical Character Recognition)
PDF/A compliance for archival
Accessibility features (PDF/UA-2)
Print production (CMYK, crop marks)
Security policies and content stripping

Currently Limited::

Some advanced multimedia features (video/audio embedding)
3D model support
Certain specialized form widgets

We maintain a public roadmap and prioritize features based on user feedback. Enterprise customers can request specific feature development.

We've built an extensive conformance testing pipeline:

**26,000+ real-world PDFs** tested against the industry-standard PDFium engine
**SSIM (Structural Similarity) analysis** to measure visual accuracy
**Continuous testing** – every code commit is validated against our entire corpus
**500 million+ PDF access** from consulting operations for ongoing validation

Currently achieving 85%+ conformance on business documents, with 68 documents scoring SSIM ≥ 0.95 (essentially pixel-perfect). We prioritize conformance improvements based on the most commonly encountered document types in enterprise environments.

If you encounter a PDF that doesn't render correctly, send it to us – we typically fix rendering issues within 24-48 hours.
