Merge report.pdf and budget.pdf, then add "CONFIDENTIAL" as a watermark.
Done — merged and watermarked. Here is your file: final-report.pdf

Everything you need, nothing you don't.

A full suite of document tools — no servers, no uploads, no compromise.

Agentic Chat

Use natural language. The AI understands context and chains commands for you.

Edit & Organize

Rotate, reorder, crop, and redact pages with simple instructions.

Merge & Split

Combine multiple PDFs into one, or split a large file into smaller parts.

Sign & Watermark

Apply your digital signature or add text and image watermarks.

Protect & Unlock

Encrypt your sensitive documents with a password, or remove protection.

Convert Files

Turn images into PDFs or convert your PDFs into different formats.

Privacy First. Always.

All file processing happens directly in your browser. Your documents are never uploaded to a server. Your data remains private and under your control.

Zero-Server File Processing

We leverage browser WASM modules (qpdf, pdf-lib) and client-side models to process documents locally. Your private contracts, financial worksheets, and tax files remain entirely under your local possession.
