# AiLoveKit > AiLoveKit is a privacy-first browser productivity suite of free PDF, image, text, developer, security, color/design and calculator tools. Core file-processing tools run locally in the user's browser, so files are never uploaded to AiLoveKit servers. AiLoveKit is built around client-side processing, no account requirement for the core tools, and practical browser-based utilities. The current site contains 81 free tools and calculators across the PDF, image, text, developer, security, color/design and calculator categories (65 file/design tools and 16 calculators), plus 9 construction calculators on AiLoveKit Build, downloadable templates, educational content and legal information. Use the linked Markdown resources (each page has an `index.md` counterpart) as the authoritative machine-readable content. Human-readable HTML pages remain the canonical public pages. The exhaustive inventory is in [/llms-full.txt](https://www.ailovekit.com/llms-full.txt). Tool capabilities, limits, privacy practices and availability can change; consult the relevant current resource rather than inferring undocumented behavior. ## Core - [AiLoveKit](https://www.ailovekit.com/): Main website and primary entry point. - [All Tools](https://www.ailovekit.com/#tools): Browse the full AiLoveKit tool suite. - [Calculators](https://www.ailovekit.com/calculators/): Hub for the 16 general calculators. - [How It Works](https://www.ailovekit.com/#how): Explains browser-based processing and the zero-upload architecture. - [FAQ](https://www.ailovekit.com/faq/): Questions about privacy, formats, limits, browsers and tool behavior. - [About AiLoveKit](https://www.ailovekit.com/about-us/): Product background, architecture principles and company information. - [Privacy Policy](https://www.ailovekit.com/privacy/): Detailed data-handling and zero-upload policy. - [Sitemap](https://www.ailovekit.com/sitemap/): Current public index of tools, pages and legal resources. ## High-Value PDF Tools - [Merge PDF](https://www.ailovekit.com/pdf/merge-pdf/): Combine multiple PDF files locally in the browser. - [Split PDF](https://www.ailovekit.com/pdf/split-pdf/): Extract page ranges or split PDFs into smaller files. - [Compress PDF](https://www.ailovekit.com/pdf/compress-pdf/): Reduce PDF file size while preserving quality. - [PDF to Word](https://www.ailovekit.com/pdf/pdf-to-word/): Convert PDF documents to editable DOCX. - [PDF to Excel](https://www.ailovekit.com/pdf/pdf-to-excel/): Extract PDF tables into XLSX. - [PDF to Markdown](https://www.ailovekit.com/pdf/pdf-to-markdown/): Convert PDF content into structured Markdown. - [OCR PDF](https://www.ailovekit.com/pdf/ocr-pdf/): Recognize text in scanned PDFs on-device. - [Protect PDF](https://www.ailovekit.com/pdf/protect-pdf/): Password-protect PDFs locally. - [Redact PDF](https://www.ailovekit.com/pdf/redact-pdf/): Permanently redact sensitive PDF content. - [Remove PDF Metadata](https://www.ailovekit.com/pdf/remove-metadata/): Remove hidden PDF metadata. - [All PDF Tools](https://www.ailovekit.com/pdf/merge-pdf/): 24 browser-based PDF tools;
