Scanning a document on your iPhone does not require a bulky flatbed scanner. The camera in your pocket, combined with the right software, can detect page edges, straighten the page, and produce a clean PDF or image in seconds. In 2026, every iPhone has a free built-in scanner, and dedicated apps add OCR, multi-page PDFs, and better export options.<\/p>\n

Two ways to scan documents on iPhone<\/h2>\n

There are two main approaches, and which one you pick depends on what you need from the scan.<\/p>\n\n\n\n\n\n\n
Method<\/th>\nBest for<\/th>\nOCR<\/th>\nMulti-page PDF<\/th>\nCost<\/th>\n<\/tr>\n<\/thead>\n
Apple Notes (built-in)<\/td>\nQuick, occasional scans<\/td>\nBasic (Live Text)<\/td>\nVia share sheet<\/td>\nFree<\/td>\n<\/tr>\n
Dedicated app (e.g. AlignScan)<\/td>\nRegular scanning, OCR, batch PDFs<\/td>\nYes<\/td>\nYes<\/td>\n20 free saves, then monthly\/yearly\/lifetime<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Method 1: Scan with Apple Notes (free, built-in)<\/h2>\n

The Notes app on every iPhone includes a document scanner. It is the easiest option if you need a quick scan and do not want to install anything.<\/p>\n

    \n
  1. Open the Notes<\/strong> app and create a new note, or open an existing one.<\/li>\n
  2. Tap the camera icon<\/strong> above the keyboard, then choose Scan Documents<\/strong>.<\/li>\n
  3. Point your camera at the document. The app highlights the page edges automatically.<\/li>\n
  4. If the corners are off, drag the dots to adjust. Tap Keep Scan<\/strong>.<\/li>\n
  5. To add more pages, scan the next sheet. When finished, tap Save<\/strong>.<\/li>\n
  6. To export a PDF, open the scan, tap the share icon, and choose Save to Files<\/strong> or another destination.<\/li>\n<\/ol>\n
    Tip:<\/strong> For text you want to copy, open the scan and long-press a word \u2014 iPhone’s Live Text lets you select and copy recognized characters.<\/div>\n

    Method 2: Scan with a dedicated app for OCR, PDFs, and editing<\/h2>\n

    If you scan regularly, need to copy text from the page, want multi-page PDFs, or need to edit PDFs (sign, merge, compress, convert), a dedicated scanner app is faster and produces cleaner results. We will use AlignScan<\/a> as an example since it combines scanning, OCR, and a full PDF toolkit with on-device processing.<\/p>\n

      \n
    1. Download AlignScan from the App Store and open it.<\/li>\n
    2. Choose Scan<\/strong> to use the camera, or import an existing image from your Photos.<\/li>\n
    3. The app detects the document edges automatically. Adjust the corners if needed.<\/li>\n
    4. Review the corrected, enhanced preview \u2014 AlignScan straightens perspective, improves readability, and formats the page in a clean A4 layout.<\/li>\n
    5. Tap OCR<\/strong> to extract text, then copy it or save it as a TXT file.<\/li>\n
    6. From your document, you can also sign, merge, split, compress, password-protect, or convert the PDF.<\/li>\n
    7. Choose your export: JPG<\/strong>, single-page PDF<\/strong>, or add more pages for a multi-page PDF<\/strong>. Save to Files, Photos, or share directly.<\/li>\n<\/ol>\n

      AlignScan is free for your first 20 saves; after that you can subscribe monthly or yearly, or unlock everything with a one-time lifetime purchase.<\/p>\n

      Tips for a clean scan every time<\/h2>\n
        \n
      • Good lighting.<\/strong> Even, soft light avoids harsh shadows across the page.<\/li>\n
      • Hold the camera parallel<\/strong> to the document for the least distortion.<\/li>\n
      • Keep the page flat.<\/strong> Curled corners are harder to detect; weigh the page down if needed.<\/li>\n
      • Leave a margin<\/strong> between the document edges and the frame so the app can find the corners.<\/li>\n
      • Use a contrasting background.<\/strong> A dark desk under a white sheet makes edge detection easier.<\/li>\n<\/ul>\n

        When to use the built-in scanner vs. an app<\/h2>\n

        The built-in Notes scanner is perfect for an occasional receipt or a single page you need to email quickly. A dedicated app earns its place when you scan several times a week, need searchable text from the page, or regularly combine multiple pages into one PDF.<\/p>\n

        Privacy note:<\/strong> AlignScan runs its scanning and OCR on the device. Your documents are not uploaded to a server unless you choose to share or export them to cloud storage.<\/div>\n

        FAQ<\/h2>\n
        \n
        \nWhere is the document scanner on my iPhone?<\/summary>\n

        The built-in scanner lives inside the Notes app. Open a note, tap the camera icon, and choose “Scan Documents”.<\/p>\n<\/details>\n

        \nCan I scan a document to PDF for free on iPhone?<\/summary>\n

        Yes. Apple Notes scans can be exported as PDF through the share sheet at no cost. AlignScan offers 20 free saves, then monthly\/yearly subscriptions or a one-time lifetime unlock.<\/p>\n<\/details>\n

        \nHow do I scan a multi-page document into one PDF?<\/summary>\n

        With a dedicated scanner app, capture each page and the app combines them into a single PDF. In Notes, scan each page into one note and share the whole note as a PDF.<\/p>\n<\/details>\n

        \nCan the iPhone scanner recognize text?<\/summary>\n

        Yes. iPhone’s Live Text can select text in a scan, and apps like AlignScan include OCR that extracts text into a copyable or savable text file.<\/p>\n<\/details>\n

        \nAre scanned documents uploaded to the cloud?<\/summary>\n

        Only if you choose to. Apple stores Notes scans in your iCloud if Notes sync is on. AlignScan processes on the device by default and only uploads when you export to a cloud service.<\/p>\n<\/details>\n<\/div>\n
