What is HEIC?

HEIC (High Efficiency Image Container) is Apple's default photo format since iPhone iOS 11 (2017). It stores photos in roughly half the file size of JPEG while maintaining the same visual quality.

The problem: Windows, Android, and most web platforms cannot open HEIC files natively. Converting to PDF creates a universally accessible, shareable format that works on every device and operating system.

Pro Tips

Use "All images → One PDF" for photo albums, reports, and portfolios.
Use "Fit to image" page size to preserve the original photo dimensions without any cropping.
Drag the file cards to reorder which photo appears on which page before converting.
Set quality to 90% for the best balance — visually identical to 100% but with a noticeably smaller PDF file.
On iOS Safari, tap the share icon and select "Save to Files" to get your HEIC photos to use with this tool.

How to Convert HEIC to PDF — Step by Step

Get your HEIC files ready

Transfer HEIC photos from your iPhone to your computer. On Windows, connect via USB or use AirDrop to Mac then transfer. On iOS you can use this tool directly from mobile Safari — tap "Browse Files" and select from Files or Photos.

Upload your HEIC files

Drag and drop your HEIC files into the upload area, or click "Browse Files". You can select multiple files at once. Each file appears as a card showing the file name and size.

Reorder if needed

Drag the file cards to set the order of pages in your PDF. The card at the top becomes page 1. Use "Add More" to upload additional files.

Choose your PDF settings

Select whether to combine all images into one PDF or get separate PDFs. Choose page size, orientation, margin, and quality. For most uses, the defaults work well.

Convert and download

Click "Convert to PDF". The tool decodes each HEIC to JPEG in your browser and builds the PDF locally. When done, click Download to save your PDF.

Why Convert HEIC to PDF?

Windows compatibility: Windows 10/11 cannot open HEIC files without the HEVC Video Extensions ($0.99 from Microsoft Store). PDF opens on every Windows PC instantly.
Email attachments: Many email clients display a blank icon for HEIC attachments. PDFs open in every email client and browser without issues.
Documents and forms: Government portals, job applications, and insurance forms require JPG or PDF uploads — not HEIC.
Portfolio and presentations: Combine multiple iPhone photos into one clean, professional PDF to share with clients, employers, or teachers.
Long-term archiving: PDF is an ISO standard (ISO 32000) guaranteed to remain accessible for decades. HEIC may become obsolete.
Print shops: Most online print services accept PDF or JPG, not HEIC. Converting ensures your photos print correctly.

Frequently Asked Questions

Why can't I open HEIC files on my Windows PC?

HEIC uses HEVC (H.265) video compression technology. Windows requires the HEVC Video Extensions codec to decode HEIC files, which Microsoft sells for $0.99 in the Microsoft Store. Without it, HEIC files appear as blank icons. Converting to PDF bypasses this entirely — PDFs open natively on every Windows version without any additional software.

Does converting HEIC to PDF reduce image quality?

At 90% quality (the default), the converted PDF is visually indistinguishable from the original HEIC photo. The conversion process: HEIC → JPEG (via heic2any) → embedded in PDF. Some minor quality reduction is inherent in re-encoding as JPEG, but at 90%+ it is imperceptible. Use 100% quality if you need archival-grade output.

Is my iPhone photos uploaded to any server?

Never. This tool uses heic2any — an open-source JavaScript library that decodes HEIC files entirely in your browser memory — and jsPDF to build the PDF locally. Your photos never leave your device. Safe for personal, medical, legal, and confidential photos. See our Zero Data Storage Policy.

How do I get HEIC files from my iPhone?

On Windows: Connect via USB and open File Explorer — navigate to iPhone → DCIM → your photos are in HEIC format. On Mac: AirDrop or USB transfer. On iOS: Use this tool directly from Safari on your iPhone — tap Browse Files → Photos to select directly. Note: iOS automatically converts to JPEG when you email or AirDrop photos "Most Compatible" — to keep HEIC for this tool, transfer via USB or Files app.

Can I combine multiple HEIC photos into one PDF?

Yes. Upload multiple HEIC files, select "All images → One PDF" in Output Mode, drag to set the page order, and click Convert. All photos are combined into a single PDF — one photo per page. This is ideal for photo albums, portfolios, insurance claim photos, and reports.

Is this tool completely free?

Yes — 100% free, no account required, no file limits, no daily caps, no watermark. Convert as many HEIC files as you need.
