How to Convert HEIC to PDF Free: iPhone Photos to PDF

By Picovert Team2026-02-234 min read

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:

  1. Convert your HEIC file to JPEG first using a free online converter. Most image-to-PDF tools work with JPEG but not HEIC directly
  2. Use Image to PDF to convert the JPEG to a PDF. You can combine multiple photos into one PDF in a single step
  3. 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:

  1. Open the HEIC file in Preview (double-click, or right-click → Open With → Preview)
  2. Go to File → Export as PDF
  3. Choose a save location and click Save. The PDF is created immediately

For multiple HEIC photos into one PDF in Preview:

  1. Select all HEIC files in Finder, right-click, and choose Open With → Preview
  2. In Preview, open the sidebar (View → Thumbnails) — all photos appear as pages
  3. Go to File → Print → PDF → Save as PDF to export all photos as a single multi-page PDF

Method 3: Mac — Photos App Export

  1. Open Photos and select the HEIC images you want to convert
  2. Go to File → Export → Export [n] Photos
  3. In the export dialog, change the format to JPEG, then click Export
  4. 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:

  1. Open the HEIC file in Microsoft Photos or Paint
  2. In Microsoft Photos: click the three-dot menu → Print → Microsoft Print to PDF
  3. 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)

  1. Open the HEIC photo in the Photos app on iPhone
  2. Tap the Share button (box with upward arrow) → Print
  3. In the print preview, pinch-to-zoom or use two fingers to expand the preview — this triggers the Share sheet for the PDF
  4. 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
