onepdf

Your PDFs never leave your browser.

An open-source, browser-only PDF toolkit. Drop a file, merge or compress it entirely on your device, download the result. No uploads, no tracking.

Repo: github.com/rahmanashis01/ONEPDF

Features

• Merge PDFs — drop multiple files, reorder and delete pages across them, export one merged PDF.
• Compress PDFs — pick High / Medium / Low (150 / 110 / 80 DPI) and download a smaller file.
• Optional Clerk auth — the tools work for everyone; sign-in lives only in the navbar.
• Upcoming — Markdown → PDF, DOCX → PDF, more formats, in-place PDF text editing.

Why

• 100% client-side. Parsed with pdfjs-dist, rebuilt with pdf-lib. No API routes touch file bytes.
• Privacy by default. Nothing persists once you close the tab.
• Modern stack. Next.js 16 (App Router + Turbopack), React 19, TypeScript, Tailwind v4, shadcn/ui, @dnd-kit, motion.
