How to convert JPG to PDF on iPhone
Fast, private conversion in Safari with no app install and no uploads.
Quick steps
- Open JPEGtoPDF.io in Safari.
- Tap Select images and choose photos from your camera roll.
- Drag cards to reorder pages, then rotate any sideways image.
- Set Page size to Letter or A4, and keep margins around 8 to 12 mm.
- Tap Convert to PDF, then share to Files, Mail, or Messages.
Best settings for iPhone documents
- Receipts and forms: 1 image per page, 144 to 200 DPI, medium compression.
- Photo-heavy PDFs: 1 image per page, 120 to 150 DPI, higher compression.
- Batch scans: 2 images per page when readability is still strong.
Common iPhone issues and fixes
Images look rotated incorrectly
Tap rotate on the thumbnail or enable Strip metadata to normalize orientation.
PDF is too large to email
Lower DPI, increase compression slightly, and avoid using Fill unless needed. See size reduction guide.
Safari tab reloads on large batches
Split the job into smaller batches (for example 20 to 40 images), then merge final files if needed.
