About My PDF Toolkit

Every PDF Tool You Need. Completely Free.

Creator

Built by Mannu Yadav. The “My” in the name is personal — Mannu — on a platform meant to compete with commercial PDF suites on usability, while beating them on privacy.

Why browser-only?

Most online PDF sites upload your files to their servers. We process with pdf.js (render / preview) and pdf-lib (mutate / export) entirely in the browser. That means lower latency, zero server storage risk, and a clear answer when someone asks where their document went: nowhere.

Architecture (judge-ready)

  1. Upload stays local via the File API (never POSTed).
  2. Shared PdfWorkspace shell: thumbnails + preview canvas + options panel.
  3. Tools call the same PDF library layer under src/lib/pdf.
  4. Download returns a Blob from memory — no cloud round-trip.
  5. Hosted on Vercel as a Next.js App Router frontend.

What makes the UX different

Organize and edit tools show real page thumbnails. Watermark has live preview. Annotate, highlight, and sign place content by clicking or dragging on the page — not by typing PDF coordinates.
