How it Works

Three steps.
Zero uploads.

PDFToolbox processes everything locally using WebAssembly-powered PDF engines baked directly into the page. There is no step where your file leaves your device.

01 — Drop

Drop your PDF

Drag a PDF onto the dropzone, or click to browse. The file is read locally by your browser. No upload happens. File info appears instantly.

02 — Configure

Pick your operation

Switch between Split, Extract, or Merge. Set page ranges, click thumbnails to select, or queue files for merging. Everything is visual and immediate.

03 — Download

Download the result

Hit the action button. Your browser processes the PDF in milliseconds and hands the file directly to your downloads folder — no server ever involved.

What's Included

Three tools.
Free, always.

The essentials, done right. No watermarks, no timers, no account — just clean results in seconds.

Split with range syntax

Enter a range like 1–3, 5, 8–10 and extract exactly those pages. Individual pages, ranges, or mixed combos — all supported.

10 pages max

Visual page selector

See every page rendered as a thumbnail before extracting. Click to select, click again to deselect. Your click order is preserved in the output PDF.

10 pages max

Multi-file merge

Queue two PDFs and drag to reorder before merging. Each file shows page count and size. Merge runs entirely in your browser — zero server contact.

2 files · 10 pages each

Offline capable

Once the page loads, internet isn't required. The PDF engines cache locally. Works on planes, air-gapped networks, anywhere without connectivity.

Fully free

Zero-latency processing

No server roundtrip means no waiting. Operations complete in milliseconds for typical documents — limited only by your device's CPU.

Fully free

Unlimited pages, 10 tools including compress, watermark, rotate, encrypt, and PDF-to-image export. One payment, yours forever.

Privacy isn't a feature — it's the architecture.

Most "free" PDF tools upload your documents to servers you don't control. You hand over a sensitive contract or a medical record and hope for the best. PDFToolbox is structurally different: your files are read into browser memory, processed by JavaScript running on your machine, and downloaded directly to your device. There are no servers, no logs, no analytics on your files, and no way for us to see your documents even if we wanted to.

Zero HTTP requests carrying your file data — verifiable in DevTools
Files garbage-collected when you close the tab — no localStorage, no IndexedDB
Works fully offline once the page has loaded once
Fully auditable — no hidden logic or obfuscation
