Why we built PDF Toolkit AI
Every PDF tool we tried either wanted an account, slapped a watermark on the output, capped file size at 5MB, or — worst — uploaded our financial statements to a server somewhere.
So we built PDF Toolkit AI: ten tools, no signup, no watermark, and (this is the part we're proudest of) every file stays in your browser. We literally can't see your documents. There's nothing to see.
What's under the hood
- pdf-lib — PDF assembly, metadata, watermarks
- PDF.js — rendering, text extraction, image extraction
- Tesseract.js — on-device OCR for 100+ languages
- JSZip — bulk download
- Web Workers — keep big files off the UI thread
Who makes this
A small team that hates signup walls and loves the open web. We launched in 2026 and ship improvements weekly.
