I Added PDF-to-Word, PDF-to-JPG, and PDF-to-PowerPoint to My Privacy-First File Tools Site

Short summary

A developer launched privacy-first PDF conversion tools (PDF to JPG, Word, PowerPoint, Google Docs) that run entirely in-browser using pdf.js, with no files uploaded to servers. The post shares two real bundling gotchas: pptxgenjs needs a Webpack module replacement plugin to strip Node built-ins, and pdf.js requires manually copied font/cMap data files to avoid broken glyphs. Built with Next.js 14 on Vercel.

  • •Four new in-browser PDF conversion tools with zero server uploads
  • •pptxgenjs bundling fix: strip node: scheme via NormalModuleReplacementPlugin
  • •pdf.js font/cMap files must be copied to /public to avoid silent glyph breakage
