<h3>MoGuan is a local PDF toolkit designed for users who handle sensitive documents. It offers a comprehensive suite of tools that operate entirely within your browser, ensuring your files never leave your computer. This privacy-focused approach makes it ideal for sensitive contracts, resumes, and financial reports.</h3><ul><li>Classic Tools (100% Local &amp; Free): Compress PDF to reduce file size while keeping text searchable or rasterizing for larger savings. Merge multiple PDFs into a single document in your preferred order. Split PDFs by extracting pages or creating individual files. Rotate pages by 90, 180, or 270 degrees. Edit pages by deleting unwanted ones, adding page numbers, watermarks, or reordering them. Encrypt and decrypt PDFs with passwords. Crop pages by trimming margins or auto-trimming whitespace. Sign PDFs by drawing or uploading a signature. Remove blank pages automatically. Add images or stamps. Apply Bates numbering for legal and audit purposes.</li><li>Conversion Tools: Convert images (JPG, PNG) to PDF, stitch PDF pages into a single long image, export PDF pages as JPG/PNG, convert PDF to editable Word (.docx) with optional AI re-flow, and convert PDF tables to Excel (.xlsx).</li><li>OCR: Extract text from scanned PDFs or images, supporting Chinese and English, running locally in your browser.</li><li>AI Tools (Powered by DeepSeek): Convert PDF to Markdown, generate AI summaries of documents, translate PDFs between 7 languages (Chinese, English, Japanese, Korean, French, Spanish, German), and ask questions directly to your PDF content. AI features send only extracted text, never the original PDF, and offer 5 free uses per day.</li></ul>MoGuan requires no login or installation and works offline for its classic tools. The user interface is bilingual, and AI prompts are optimized for Chinese content.
