About

Built for privacy,
by design.

PurePDF was built because converting images to PDF shouldn't require uploading your files to a stranger's server. Your images are yours — they should stay on your device.

Our Mission

We believe file conversion tools should be fast, free, and private by default. PurePDF converts images to PDF entirely in your browser using the Canvas API and a hand-built PDF encoder. There are no servers, no accounts, no limits, and no data leaving your device.

How It Works

When you drop an image into PurePDF, your browser reads the file locally, renders it to a Canvas element, encodes it as JPEG data, then wraps it in a minimal valid PDF structure — all in memory. The resulting PDF is offered as a download directly from your browser. Nothing is sent over the network.

Zero uploads

Files are processed in your browser memory. No data ever leaves your device.

Instant results

No waiting for server responses. Conversion happens at the speed of your CPU.

No account

No signup, no email, no tracking. Just open and convert.

Works offline

Load the page once, then disconnect. PurePDF still works.

Our Principles

  • No server uploads — every byte stays on your device.
  • No registration — open the tool, convert, done.
  • No watermarks — the PDF you get is yours, clean.
  • No ads in the converter — we keep the tool distraction-free.
  • No file size limits — we trust your device.
  • Open forever — PurePDF will always be free.

Supported Formats

PurePDF currently supports converting:

  • JPG / JPEG — most common photo format
  • PNG — lossless format with transparency support
  • WebP — modern format used on the web
  • GIF — animated and static GIFs (first frame)
