About PDF Toolkit
We believe handling PDF shouldn’t mean installing heavy software, paying subscriptions, or uploading sensitive files to someone else’s server.
PDF Toolkit is a private, fast and free document workspace that runs 100% in your browser. 100 tools, 19 languages, 0 files leave your device.
Why we built this
We were frustrated. To do something as simple as merge two PDFs or compress a file for email, you had to: download a 500MB installer, create an account, upload a contract to an unknown server, wait, and then hit a paywall for the next file.
For students, freelancers, teachers, lawyers and teams handling resumes, invoices, contracts and research papers every day, that experience is broken. It’s expensive, fragmented and — most importantly — unsafe for private documents.
So we asked: what if the browser itself could be the PDF engine? With modern WebAssembly, pdf-lib and pdf.js, it can. We rebuilt the essential PDF workflow as a static, serverless site where the page is the app and your device is the server.
What problems we solve
Every tool is a direct answer to a real Google search and a real workflow. Not SEO fluff — real “I need this now” tasks:
📄 Organize
Merge, split, delete, extract, reorder, rotate, duplicate and repair pages. The plumbing of everyday PDF work.
🔄 Convert
PDF ↔ Word / Excel / PowerPoint / JPG / PNG / WebP / HTML / CSV / Markdown / PDF/A and back. Lossless where it matters.
✏️ Edit
Crop, resize, add page numbers, headers/footers, text, images, highlights and links without touching the original fonts.
🗜️ Compress
Reduce size for email, e-filing and web upload — with a clear before/after saving.
🔒 Security
Password-protect, remove restrictions, redact and flatten. Privacy is not a feature, it’s the default.
🖼️ Image to PDF
JPG, PNG, WebP, SVG to PDF and back, plus extract images and text from any PDF.
✍️ Sign
Fill forms, type or draw a signature, add it to any page and download.
🔍 OCR
Make scanned PDFs searchable and turn them into editable Word/Excel/text — all locally.
From “compress PDF for Gmail” to “scanned PDF to Word for thesis”, the job is done in three steps: Upload → Process → Download. No signup, no watermark, no “free for 2 files”.
Our principles
- Private by design — Files never leave your browser. No upload server to hack, no retention policy to trust. Close the tab and the data is gone.
- Free for core tasks — 100 tools are free today and will stay free for individuals. We earn via non-intrusive AdSense, not by holding your files hostage.
- Fast and honest — WebAssembly + static CDN = desktop-class speed with honest progress, error messages and 44px touch targets.
- Accessible and global — 19 languages, keyboard-navigable, screen-reader labels, dark mode and mobile-first. Default is English, but everyone is at home.
Technology you can inspect
We are fully static and auditable: HTML generated at build, hosted on Cloudflare Workers, no database, no backend conversion API. Heavy work is done by pdf-lib, pdf.js, docx, xlsx and pptxgen loaded as self-hosted scripts — no third-party CDN unless it is truly global. This is why we can promise privacy and still pass Google’s SEO and performance checks.
Who we serve
Students merging lecture notes, job seekers exporting resumes, ops compressing invoices, lawyers redacting contracts, designers cropping and watermarking proofs — if you touch a PDF, this is built for you. No account, no tracking beyond anonymous AdSense.
Roadmap
100 tools today is the foundation. Next: higher-fidelity Office rendering, true outline/bookmark editing, and on-device OCR with WebAssembly Tesseract — all still 100% local. We ship a little every week; your feedback decides the order.
