About Bisnep

Free, private, browser-based PDF and image tools for everyone.

What is Bisnep?

Bisnep is a free, browser-based collection of PDF and image tools built for anyone who needs to work with documents quickly and privately. Whether you're a student, a professional, or just someone dealing with a tricky PDF, our tools are designed to be simple — no software to install, no account to create, no file uploaded to any server.

Every tool runs entirely in your browser using JavaScript. Your files are processed locally on your device and never leave it. We believe useful tools should be free and private for everyone.

Private by Design

Files never leave your browser. Nothing is uploaded to any server at any point. You can verify this yourself by opening your browser's network tab.

Always Free

No fees, no subscriptions, no premium tiers. Every tool on Bisnep is completely free to use with no limits on how many files you process.

Works Everywhere

All tools work on desktop, tablet, and mobile. No app to install — open your browser and start using any tool immediately.

No Sign-up

Use any tool without creating an account. We don't ask for your email, your name, or any personal information to use the site.

How do the tools work?

All tools use JavaScript libraries that run directly in your browser:

  • PDF.js — reads and renders PDF files (the same library used by Firefox)
  • pdf-lib — creates, modifies and saves PDF files
  • JSZip — packages multiple output files into a ZIP archive
  • SheetJS — reads Excel spreadsheets
  • Mammoth.js — reads Word documents

None of these libraries send your data anywhere. Everything stays on your device.
