Add Page Numbers to Your PDFs Instantly

Whether you're organizing a long report, preparing a manuscript, or simply keeping your documents structured, adding page numbers is essential. Our free online tool makes it incredibly easy to insert page numbers into your PDF files in seconds. You have full control over the placement, size, and starting number, ensuring your document looks professional and is easy to navigate.

What This Tool Does

This client-side tool allows you to insert customized header or footer page numbers to PDF directly in your browser. Without requiring any installation or software downloads, you can securely select your documents, apply your desired parameters, and obtain a high-fidelity numbered PDF in seconds.

Who Should Use It

Ideal for students compiling homework, legal professionals handling sensitive client files, healthcare administrators matching HIPAA standards, and businesses protecting intellectual property. If you need absolute data confidentiality and cannot risk uploading files to a public cloud, this is your solution.

Supported File Types

  • Input format: Standard PDF files (.pdf) , as well as source documents like image files or Office spreadsheets.
  • Output format: Clean numbered PDF format.
  • Constraint: Fully preserves original vector shapes, metadata structures, and hyperlinks.

Privacy Model

100% Local-First. Your files are never uploaded to our servers. We do not operate external caches, databases, or third-party tracking mechanisms. All data resides in temporary device memory.

Processing Method

Operations are computed inside the browser’s secure sandbox environment. WebAssembly (Wasm) and Javascript modules read and re-compile document byte streams at near-native execution speed.

Browser Compatibility

Fully compatible with Google Chrome, Apple Safari, Mozilla Firefox, Microsoft Edge, and mobile browsers on Windows, macOS, Linux, ChromeOS, iOS, and Android.

Security Standards

Files remain isolated inside the browser tab’s execution threads. We employ symmetric AES-256 standards when handling passwords and encrypting outputs.

Performance limits

Sub-second response times for typical documents. Since memory allocation happens locally, performance scales directly with your device's processor and free RAM.

Common Use Cases

Consolidating research papers, compressing visa documents under consulates’ limits, hiding confidential digits via black box shapes, or e-signing client receipts offline.

Troubleshooting
