Add highlights, text, signatures, and opaque covers, or fill compatible PDF form fields. Undo app-created marks, blocks, and page changes before saving a new copy.
Scan a multi-page document, turn selected photos into a PDF, merge files, or extract, rotate, delete, and reorder pages.
Search extractable text by page, listen with Read Aloud, export rendered pages as PNG, run OCR to TXT, print, share, compress, or protect a compatible copy.
Ask questions about extractable document text or make a concise summary without sending the PDF to a cloud AI service.
Straightforward by design
Help when something gets in the way
Start with the matching step below. If it does not resolve the issue, send the requested device details and we will investigate.
Confirm the file has finished downloading in Files. For a password-protected PDF, choose Tools → Unlock PDF and enter the known password to create an unlocked copy. Damaged PDFs and some uncommon formats may not be compatible.
Those tools require selectable PDF text. Recognize Text can export a separate TXT file, but it does not make the original PDF searchable. Ask PDF attempts local OCR automatically when a document has no native text.
Open the PDF and tap inside an app-created block to select it. Drag anywhere inside the selected block to move it, or drag the blue bottom-right handle to resize it. Content already baked into the source page is not directly editable.
Choose Save Copy, select a writable Files location, and confirm the device has free storage. Your original remains unchanged if an export is cancelled or fails.
They require iOS or iPadOS 26, an eligible Apple Intelligence device, and supported language and system settings. PDF Pro AI Editor shows its local extractive fallback when those requirements are not met; it does not send the document to a cloud fallback.
For scanning, open Settings, find PDF Pro AI, and allow Camera access. For Photos to PDF, reopen the system photo picker and review Screen Time or device restrictions if selection remains unavailable. Neither is required for opening PDFs from Files.
Clear output expectations
These details help you choose the right workflow before you export a new copy.
Covers visible content in a flattened output. It is not certified redaction.
Works with compatible AcroForm fields. XFA, JavaScript, calculations, and certificate signatures are not supported.
Exports recognized text as a UTF-8 text file. It does not create a searchable PDF.
Small File mode creates an image-based copy. High Quality and Balanced preserve structure where PDFKit supports it. A reduction is reported only when measured output is smaller.
