JPG to PDF on Mobile: Convert Photos to PDFs on iPhone & Android

Converting JPG images to PDF on your phone is fast and useful—whether you’re saving receipts, combining photos into a single document, or preparing files for sharing. Below are simple, reliable methods for both iPhone and Android, plus tips for quality, file size, and organizing pages.

iPhone (iOS)

1. Using the Files app (no download)

   • Open the Photos app and select the images you want.
   • Tap the Share icon → Save to Files → choose a folder → Save.
   • Open the Files app, navigate to the folder, tap the three-dot menu → Select → choose the images → tap the three-dot menu → Create PDF.
   • The PDF will appear in that folder; tap to open, share, or rename.

2. Using the Shortcuts app (combine & automate)

   • Open Shortcuts → Gallery → add “Make PDF” or create a shortcut that takes Photos as input and uses Make PDF.
   • Run the shortcut, select photos, then save or share the resulting PDF.

3. Using Print to PDF (for single or multiple images)

   • In Photos, select images → Share → Print.
   • Pinch-out on the print preview to create a PDF, then tap Share to save to Files or send via Mail/Message.

4. Third-party apps (when you need features)

   • Recommended: Adobe Scan, Microsoft Lens, or Scanner Pro for OCR, auto-cropping, and advanced compression.
   • Use app settings to adjust image quality and page order before exporting.

Android

1. Using Google Photos or Photos app (Save as PDF)

   • Open Google Photos, select images → tap Share → Print.
   • In the print preview, choose Save as PDF (printer dropdown) → Save.
   • Choose folder in device storage or Google Drive.

2. Using Files by Google or Files app

   • Save images to a single folder.
   • Open the folder, select images → tap the three-dot menu → Print or Save as PDF (option names vary by device).
   • Save the PDF locally or to cloud storage.

3. Using Microsoft Lens or Adobe Scan

   • Scan or import photos, reorder pages, crop, and adjust quality.
   • Export directly as PDF, with optional OCR for searchable text.

4. Built-in Share to PDF (some OEMs)

   • Many Samsung and other OEM Gallery apps include “Save as PDF” in the Share or More menu—use that for a quick conversion.

Tips for Best Results

• Order pages before creating the PDF by arranging photos in the app’s selection view.
• Crop and rotate images to remove backgrounds and align content.
• Reduce file size: lower image quality or use compression in app settings; export grayscale if color isn’t necessary.
• Combine different formats: most apps accept JPG, PNG, and HEIC—convert HEIC to JPG first if an app doesn’t support it.
• Use OCR (Adobe Scan, Microsoft Lens) to make PDFs searchable if you need text extraction.
• Privacy: delete temporary images or scans from the app if they contain sensitive info.

Quick Comparison (when to use what)

• Files/Print method: Fast, no extra apps.
• Shortcuts (iOS): Automates repetitive conversions.
• Scanner apps: Best for OCR, cropping, and clean scans.
• Google Drive/Cloud save: Convenient for backups and sharing.
