PDF Editor & Reader: Sign PDF

AppChunks PDF Editor is a complete PDF toolkit that runs entirely on your phone. Edit, sign, scan, convert, merge and protect PDF files — 49 professional tools in one app, and every one of them works offline.

Most PDF apps upload your document to a server first. AppChunks PDF Editor never does. Contracts, tax forms, medical records and IDs are processed on your device and stay there. No account, no cloud, no connection required.

▶ PDF EDITOR — CHANGE THE ACTUAL CONTENT
• Tap a paragraph and retype it — real text editing, not just a text box on top
• Swap fonts, replace images, and white out anything you don't want
• Add text, images, shapes, arrows and freehand drawing
• Highlight, underline, strikethrough and leave sticky notes
• Undo and redo up to 24 steps, then flatten it all into the page

▶ FILL & SIGN — E-SIGNATURE
• Fill PDF forms, including interactive AcroForm fields
• Draw, type or import your signature and drag it into place
• Certificate-based digital signature (PKCS#7) when one is required
• Sign a PDF and send it back in under a minute

▶ DOCUMENT SCANNER & OCR
• Scan to PDF with the camera — automatic edge detection and perspective fix
• On-device text recognition (OCR) turns a scanned PDF into searchable, copyable text
• Deskew crooked scans and clean up the page
• Scan QR codes and barcodes, or generate your own
