How to Add Page Numbers to PDF Offline & Privately

Processing and managing PDF documents is a daily operational task for legal, healthcare, and corporate departments. However, uploading file streams to typical remote servers puts your data confidentiality at risk. This step-by-step guide walks you through how to execute these functions locally in-browser with zero uploads.

Step-by-Step Instructions

1. Open the PDF Page Numberer: Select 'Number PDF' in the left navigation sidebar.
2. Add Your PDF: Drag and drop your document into the dashed box area or click to select from file storage.
3. Configure Settings: Select your page positioning alignment (e.g. Bottom Right), formatting template (e.g. Page X of Y), font size, start number, and color.
4. Add Numbers Locally: Click **'Add Page Numbers'**. The processing executes locally in browser memory.
5. Save PDF Output: The numbered file downloads automatically to your device.

Local Page Structure Modification

PDF page numbering inserts metadata-indexed text content streams. Using client-side scripts, PDFCraft computes layout coordinates directly on your device's CPU and renders the number layers on top of each page frame. Your files are processed entirely in temporary browser memory and never uploaded.

Custom Placements & Offsets

Select from 6 standard layout grid alignments (top-left, top-center, top-right, bottom-left, bottom-center, bottom-right) to match custom report formatting specifications. Enter start indices (e.g., beginning at 5) or specify custom page ranges (e.g., '3-10') to bypass numbering on cover sheets.
