Scan documents, edit PDFs, sign forms, and convert files — all in one fast, secure app. New: AI summary, multi-page highlights, and one-tap Word export.
PDF Tools Editor is the only PDF app you will ever need on iPhone. Scan, view, edit, annotate, sign, convert, merge, split, compress, and protect — every PDF task in one beautifully designed app.
EVERYTHING YOU CAN DO WITH PDFs
SCAN ANYTHING TO PDF
Auto-detect document edges with your camera. Capture multi-page scans into a single crisp PDF. Choose color, grayscale, or black-and-white modes. Built-in OCR makes every scan searchable.
POWERFUL PDF EDITOR
Highlight text in twelve colors. Draw freehand with adjustable pen widths. Add text using custom fonts and sizes. Insert shapes such as rectangle, circle, and line. Place handwritten signatures anywhere on the page. Recolor any annotation in one tap. Apply multi-page annotations such as highlights that span across pages. Undo or redo every change. Resize and rotate any element.
SIGN PDFs LIKE A PRO
Draw your signature with finger or Apple Pencil. Save signatures for reuse. Place them on any page with a single tap. Capture works correctly in both light and dark mode without changing your ink color.
CONVERT PDF AND BACK AGAIN
Convert PDF to Word using real on-device RTF conversion. Convert PDF to images, Excel, or PowerPoint. Convert Word, Excel, PowerPoint, and images back to PDF. Choose the page size when converting images. Edit converted Word files inside the app.
ORGANIZE AND MANAGE
Merge multiple PDFs into one. Split a PDF by page ranges. Compress files to shrink size. Rotate pages individually. Add page numbers automatically. Add custom watermarks. Multi-select files for batch share or delete.
SECURE YOUR DOCUMENTS
Password-protect any PDF. Remove passwords from your own PDFs. Files stay on your device by default — nothing is uploaded.
AI ASSISTANT
AI Summarize condenses long PDFs into key points. AI Chat lets you ask questions about your document. Save summaries as new PDFs in your library.
