Professional Client-Side PDF Editing with Uncompromising Privacy
Most online PDF editors (such as Sejda or Smallpdf) require you to upload your files to remote cloud servers for server-side processing. For confidential legal contracts, business proposals, medical charts, and tax filings, uploading sensitive files introduces serious data privacy and compliance risks.
AirPDF solves this by executing the entire editing workflow 100% client-side directly in your browser. Using modern WebAssembly and native PDF vector streams, your files are loaded, parsed, modified, and saved inside local device memory. Zero bytes are uploaded to our servers, and no document is ever logged or stored.
Sejda-Parity Toolbar Built on Native Vector Operations
AirPDF features an expansive 11-tool suite designed for professional document workflows:
- Text: Click anywhere on a page to insert custom text. Choose from multiple font sizes (12pt to 32pt) and colors (Obsidian Black, Deep Blue, Crimson Red, Crisp White).
- Edit Existing Text: Click any detected text line to automatically cover it with a matched whiteout box and type replacement text seamlessly at the same coordinates.
- Images: Insert PNG and JPEG image assets with fluid drag handles for resizing and positioning.
- Annotate: Add vibrant 35% opacity highlighter boxes (yellow, green, cyan) or strikethrough lines.
- Shapes: Draw vector rectangles and ellipses with adjustable border widths and optional fills.
- Whiteout (Visual Cover Only): Draw opaque white rectangles to obscure unwanted headers, margins, or visual elements.
- Interactive Forms: Fill out existing AcroForm text fields and checkboxes, or create new interactive form inputs.
- Links: Define clickable rectangular hyperlinks linking to external web URLs.
- Signatures: Create signatures by drawing freehand vector lines, typing your name in handwriting script, or uploading an image.
- Find & Replace: Search document text and automatically replace target occurrences with visual whiteout and replacement text.
- Page Management: Reorder pages (
▲/▼), rotate individual sheets (↻90°), and delete unnecessary pages (🗑️).
TrueType Bengali (বাংলা) Typography Support
Standard PDF generation engines frequently fail when handling South Asian complex scripts, displaying empty boxes or throwing character encoding exceptions. AirPDF integrates @pdf-lib/fontkit with embedded Noto Sans Bengali TrueType font assets. Whether adding English notes or writing Bengali text (বাংলা নথি সম্পাদনা), every conjunct and glyph renders with typographic fidelity.
Honest Security & Redaction Disclosure
We believe in complete technical transparency with our users. When using our Whiteout tool, an on-screen notice explicitly reminds you that whiteout is visual cover only. Because underlying text streams remain extractable from raw PDF streams, visual whiteout should never be substituted for cryptographic data sanitization when submitting court documents or regulatory filings.
