Why Convert Photos to PDF on Mobile?
In India and around the world, smartphones have become our primary cameras. We capture everything—from important documents to precious memories—using our phones. When it comes to sharing or submitting these images, PDF format often becomes necessary.
Government Form Submissions
Most government portals (UPSC, SSC, passport, visa applications) require documents in PDF format. Converting directly on mobile saves the step of transferring to a computer.
Professional Sharing
Sending photos as PDFs appears more professional than loose image files. Documents, proposals, and portfolios benefit from PDF's universal compatibility.
WhatsApp & Messaging
Converting WhatsApp images to PDF maintains quality and allows easy printing. PDFs don't get recompressed when forwarded.
Bank & Office Submissions
KYC documents, loan applications, and office forms often require ID proofs and photos in PDF format.
The convenience of handling everything on your phone—from taking the photo to generating and sharing the PDF—eliminates friction and speeds up your workflow significantly.
No App Needed: The Browser-Based Revolution
Many users automatically search for apps when they need to convert photos to PDF. But app-based solutions come with significant drawbacks:
⚠️ Problems with PDF Converter Apps
- Intrusive Ads: Most free apps display full-screen ads, interrupting your workflow
- Privacy Risks: Apps often upload your photos to their servers for processing
- Storage Space: Apps consume precious phone storage (50-200MB+)
- Permissions: Many request unnecessary permissions (contacts, location, etc.)
- Limited Features: Free tiers often add watermarks or limit conversions
- Performance: Poorly coded apps drain battery and slow your phone
âś… Browser-Based Solution Benefits
- Zero Installation: Works instantly in any mobile browser
- Maximum Privacy: Files never leave your device
- No Storage Used: No app to install or update
- No Permissions: Only accesses photos you explicitly select
- No Watermarks: Clean, professional output every time
- Always Updated: You always get the latest version automatically
Photo to PDF is built specifically with mobile users in mind. The interface is touch-optimized, buttons are sized for fingers (not mouse cursors), and the entire experience is designed for the vertical mobile screen.
Step-by-Step Guide for Android
Whether you use a Samsung, Xiaomi, Redmi, Realme, OnePlus, or any other Android phone, here's how to convert photos to PDF:
Open Your Browser
Launch Chrome, Firefox, Samsung Internet, or any browser you prefer. All modern Android browsers support the required features.
Navigate to Photo to PDF
Type phototopdf.in in the address bar and press enter. The mobile-optimized site loads instantly.
Tap the Upload Area
Tap the large upload box in the center. You'll see options to choose from your gallery or take a new photo with your camera.
Select Your Photos
Navigate to your photos and tap to select. Hold down on one photo, then tap others to select multiple images at once. Tap "Done" or "Select" when finished.
Arrange & Configure
Reorder photos by long-pressing and dragging. Scroll down to adjust quality, page size, and orientation settings.
Generate & Download
Tap "Generate PDF". The file downloads automatically to your Downloads folder. Find it in File Manager → Downloads.
Android Tip: After downloading, you can directly share the PDF from the notification or through your file manager by long-pressing on the file.
Step-by-Step Guide for iPhone
iPhone users (including iPad) can follow these steps to convert photos to PDF using Safari or Chrome:
Open Safari or Chrome
Safari works best for iOS integration, but Chrome and Firefox also work perfectly.
Go to Photo to PDF
Enter phototopdf.in in the address bar. The site is optimized for iOS and follows Apple's design guidelines.

Select Multiple Photos
In the iOS photo picker, tap to select individual photos. A blue checkmark appears on selected images. Tap "Add" when finished.
Reorder & Customize
Touch and hold a photo to drag it to a new position. Adjust quality, page size, and margins using the options below the photos.
