iPhone photos are saved in HEIC format by default. HEIC is efficient for storage, but most PDF readers, email clients, and document workflows expect JPEG or PDF — not HEIC. Converting HEIC to PDF is useful when you need to share multiple photos as a single document, submit photos for a form, or archive iPhone photos in a universal format. Here are the fastest free methods for Mac, Windows, and online.
Method 1: Online Converter (Any Device)
The fastest method that works on any device — no app needed:
- Convert your HEIC file to JPEG first using a free online converter. Most image-to-PDF tools work with JPEG but not HEIC directly
- Use Image to PDF to convert the JPEG to a PDF. You can combine multiple photos into one PDF in a single step
- Download the PDF. No account or software required
This two-step process (HEIC → JPEG → PDF) takes under 2 minutes for a single photo and works on iPhone, iPad, Mac, Windows, and Android.
Method 2: Mac — Preview App (Built-in, Free)
Mac users can convert HEIC to PDF directly using the Preview app — no additional software needed:
- Open the HEIC file in Preview (double-click, or right-click → Open With → Preview)
- Go to File → Export as PDF
- Choose a save location and click Save. The PDF is created immediately
For multiple HEIC photos into one PDF in Preview:
- Select all HEIC files in Finder, right-click, and choose Open With → Preview
- In Preview, open the sidebar (View → Thumbnails) — all photos appear as pages
- Go to File → Print → PDF → Save as PDF to export all photos as a single multi-page PDF
Method 3: Mac — Photos App Export
- Open Photos and select the HEIC images you want to convert
- Go to File → Export → Export [n] Photos
- In the export dialog, change the format to JPEG, then click Export
- Use Preview or an online tool to convert the exported JPEGs to PDF
The Photos app exports HEIC as JPEG automatically when you choose JPEG format — you don't need a third-party converter for the HEIC step.
Method 4: Windows — Microsoft Photos or Paint
Windows 10/11 supports HEIC natively if you have the HEIC codec installed (free from the Microsoft Store, or included with some Windows 11 versions). Once installed:
- Open the HEIC file in Microsoft Photos or Paint
- In Microsoft Photos: click the three-dot menu → Print → Microsoft Print to PDF
- Set the paper size, orientation, and print. Windows saves a PDF to the chosen location
If HEIC files don't open on Windows, first convert them to JPEG using a free online HEIC-to-JPEG tool, then print to PDF from any image viewer.
Method 5: iPhone — Print to PDF (No Computer Needed)
- Open the HEIC photo in the Photos app on iPhone
- Tap the Share button (box with upward arrow) → Print
- In the print preview, pinch-to-zoom or use two fingers to expand the preview — this triggers the Share sheet for the PDF
- Tap the Share button in the print preview → Save to Files or share directly to email
This creates a PDF from the HEIC photo directly on your iPhone, no computer required.
Converting Multiple HEIC Photos to One PDF
If you need to combine multiple iPhone photos into a single PDF document:
- On Mac: select all photos in Finder → right-click → Quick Actions → Create PDF. macOS creates a multi-page PDF automatically
- Online: use Image to PDF converter. Upload multiple HEIC or JPEG files, arrange the order, and download as one PDF
- On iPhone: use the Files app — select multiple HEIC photos, tap Share → Create PDF. iOS 16+ supports this natively
File Size After HEIC to PDF Conversion
A single HEIC photo from a modern iPhone is typically 2–5 MB. After conversion:
- HEIC → PDF (via JPEG intermediate): typically 2–8 MB per photo — PDFs preserve image quality without additional compression
- For smaller PDFs, compress the JPEG before converting to PDF, or use PDF compression on the final file
- A 10-page PDF with iPhone photos at full quality is typically 20–50 MB. For email attachments, compress the images first or use a PDF compressor
HEIC to PDF Conversion Summary
- Fastest (any device): HEIC → JPEG online, then JPEG → PDF
- Mac (built-in): Preview → File → Export as PDF
- Mac (multiple photos): Finder → select all → Quick Actions → Create PDF
- iPhone (no computer): Photos app → Share → Print → pinch → Share PDF
- Windows: open in Photos or Paint → Print → Microsoft Print to PDF
