Jawapan ringkas
The most direct native method: in the Files app, long-press any image file (JPEG, HEIC, PNG) and choose Quick Actions → Create PDF; the PDF appears in the same folder instantly, entirely on-device. Alternatively from Photos: tap Share → Print → pinch outward on the preview thumbnail to open a PDF view → tap Share again → Save to Files. Both methods are built into iOS, require no additional app, and produce a one-page PDF containing the image.
ScanTo Pro does this on your iPhone: it scans to a clean PDF, runs on-device OCR, and can lock files with Face ID — a pay-once app with no subscription. Check the App Store listing for current features.
Apa yang perlu dipertimbangkan sebelum memilih
- Files app 'Quick Actions → Create PDF' is the fastest native method — one long-press, done
- Photos app Share → Print → Pinch method also works and allows multi-image PDFs
- Both methods are entirely on-device: the image data never leaves your iPhone
- The resulting PDF embeds the image at approximately screen resolution (Print method) or original resolution (Quick Actions)
- For batch conversion or custom page sizing, a dedicated app provides more control

Soalan Lazim
Can I convert a HEIC photo (iPhone's default format) to PDF the same way?
Yes. The Files app Quick Actions → Create PDF and the Photos Print method both handle HEIC natively on-device, so you do not need to convert to JPEG first.
Does converting a photo to PDF affect its image quality?
The Quick Actions method in Files generally preserves the original image quality; the Print-to-PDF method re-renders at screen resolution (typically 72–150 effective DPI), which may reduce quality compared to the source photo.
Can I set a custom page size (A4, Letter) when converting a photo to PDF on iPhone natively?
The native iOS methods do not offer page-size selection — the PDF page is sized to the image dimensions. A third-party scanner or PDF app is required if you need an A4 or Letter-sized output.
