What's the story behind your product?

PDFdays's answer

Most popular online PDF tools charge costly subscriptions or restrict free users while requiring them to upload confidential documents to third-party cloud servers. PDFdays was built to provide a clean, modern alternative powered entirely by client-side browser technology. By running conversion, merging, and splitting algorithms directly on the user's device, PDFdays gives everyone a fast, secure, and confidential file toolkit without paywalls, accounts, or tracking.

How would you describe the primary audience of your product?

PDFdays's answer

Privacy-conscious professionals, remote workers, freelancers, students, and small business teams (especially in legal, financial, healthcare, and education fields) who regularly handle PDFs and images and need fast, reliable conversions without exposing sensitive records to third-party cloud servers.

Which are the primary technologies used for building your product?

PDFdays's answer

React 18, TypeScript, Vite, Tailwind CSS, pdf-lib, pdfjs-dist, HTML5 Canvas API, UTIF2, and fflate (for client-side ZIP archiving).

What makes your product unique?

PDFdays's answer

PDFdays processes all documents and images 100% inside your browser using client-side JavaScript, Canvas, and WebAssembly libraries. Unlike traditional online converters, files are never uploaded to any remote server, ensuring complete data privacy. There are no account requirements, no artificial file size or daily task limits, and no watermarks, with batch processing and single ZIP downloads fully supported in 26 languages.

Why should a person choose your product over its competitors?

PDFdays's answer

  1. Guaranteed Privacy: Files never leave your local device, making it safe for confidential contracts, financial statements, medical files, and identity documents.
  2. Truly Free: Major competitors limit free users to 1–2 tasks per day or gate batch downloads behind paywalls; PDFdays is completely free with zero sign-up required.
  3. No Queue Delays: Processing executes instantly on your device's hardware without waiting for slow cloud uploads or server queues.
