SEOAnalytics Lab：我打造了 50+ 款免費 SEO、文字、圖片及 PDF 網上工具（大多在瀏覽器內運行）
I built 50+ free online tools for SEO, text, images and PDF (most run in your browser)
一名網頁開發學生建立 SEOAnalytics Lab，提供 50 多款免費 SEO、文字、圖片及 PDF 網上工具。大部分工具在瀏覽器內運行，檔案和文字不會離開用戶裝置；少數工具（例如 Word 轉 PDF）則需經伺服器安全轉換，檔案不會儲存。網站免費使用，毋須註冊。
I am a web development student, and I built SEOAnalytics Lab, a website with free online tools that I wanted for my own work.
It has more than 50 tools in a few groups:
- Text tools: word counter, case converter, text summarizer
- Image tools: image compressor, resizer, background remover, upscaler
- PDF tools: merge PDF, split PDF, JPG to PDF, Word to PDF, PDF to Excel
- SEO tools: meta tag generator, Open Graph generator, canonical tag and hreflang generators, robots.txt generator
- Calculators: age, BMI, loan, GPA, compound interest
How it works
Most tools run entirely in your browser, so your files and text never leave your device. A few tools, such as converting Word files to PDF, need a server, so those files are sent securely, converted and not stored.
What I used
- Next.js and Tailwind CSS for the website
- Express and MongoDB for accounts and the contact form
- Gotenberg (LibreOffice) and a small Python service for the document converters

It is free and needs no signup. I would love your feedback, especially on which tool you would like to see next.
