🧪 PDF Alchemy

A beautiful PDF tool that works entirely in your browser. No uploads, no servers, no tracking.

What it does

Manipulate PDFs right in your browser without uploading anything to a server. Your files stay on your device.

11 Tools:

• Merge multiple PDFs
• Split PDFs by page range or burst into individual pages
• Organize pages (drag to reorder, rotate, delete)
• Compress PDFs (rasterize or lossless re-save)
• PDF ↔️ Images (JPG / PNG / WebP)
• Add text watermarks (size, color, opacity, position)
• Add page numbers (formats, position, start at, skip first)
• Edit metadata (title, author, subject, keywords)
• Extract text
• Unlock PDFs (removes owner restrictions; rasterizes when needed)
• In-app PDF preview

Why it's cool

Known Limits

• Very large PDFs (500+ pages) may be slow without Web Workers
