NGPDFs offers a suite of PDF tools designed for maximum privacy and efficiency. All standard operations are performed locally within your browser, ensuring your files never leave your device. This means no uploads, no watermarks, and no account creation are necessary.

• Page Management: Merge multiple PDFs, split existing ones into separate files, reorder, rotate, duplicate, or delete pages visually, and crop or resize pages.
• Compression: Shrink PDF file sizes locally with options to target specific sizes like 100 KB, 200 KB, or 2 MB, while maintaining honest quality.
• Editing & Annotation: Add watermarks, page numbers, edit text directly, add text boxes, images, and whiteout. Sign PDFs, fill forms, and add custom headers/footers. Transform typed notes into handwriting and combine note photos into PDFs.
• Conversion to PDF: Convert images (JPG, PNG, WebP), Markdown, DOCX, XLSX, PPTX, HTML, CSV, eBooks (EPUB, TXT), audio transcripts, and scanned documents into PDF format locally.
• Conversion from PDF: Convert PDF pages to JPG or PNG images, extract pages as images into a ZIP file, recover text into TXT, Markdown, or JSON formats, invert PDF colors, convert PDF to editable Word documents, Excel tables, PowerPoint slides, HTML, EPUB ebooks, or audio.
• OCR & Security: Make scanned PDFs searchable with on-device OCR. Remove metadata, compute file fingerprints (SHA-256), flatten forms, encrypt PDFs with AES-256, remove passwords, unlock permissions, redact sensitive content, and scan for privacy risks.

The application works offline once loaded and is ideal for sensitive documents or when internet connectivity is unreliable. Experience a truly local-first approach to PDF manipulation.
