How to Convert HEIC to PDF
Open the Image ↔ PDF Converter, switch to "Image → PDF", drop your HEIC files, and click Convert. On modern browsers (Chrome 121+, Edge 121+, Safari 17+) HEIC decodes natively — nothing is uploaded.
Key takeaways
- HEIC is the default photo format on iPhone and iPad.
- Browser support: Chrome 121+, Edge 121+ and Safari 17+ decode HEIC natively.
- Firefox does not decode HEIC — convert the photos to JPG first, or use Safari/Chrome.
- Batch: many HEIC photos become one PDF, one photo per page.
- No app needed: no iTunes, no third-party converter, no account.
- 100% private: decoding happens in your browser. Photos never leave your device.
What is a HEIC file?
HEIC (High Efficiency Image Container) is the format Apple uses by default for photos on iPhone and iPad. It stores the same picture as JPG in roughly half the space, which is why Apple switched to it. The catch is that many programs — and some browsers — cannot open it.
Browser support for HEIC
| Browser | Opens HEIC | Notes |
|---|---|---|
| Safari 17+ | Yes | Best support, including on iPhone and Mac |
| Chrome 121+ | Yes | Desktop and Android |
| Edge 121+ | Yes | Same engine as Chrome |
| Firefox | No | Convert the photo to JPG first |
How to convert HEIC to PDF
- On your iPhone, make sure the photos are saved to Files or transfer them to your computer (AirDrop, iCloud, or a cable).
- Open the Image ↔ PDF Converter and switch to "Image → PDF".
- Drag in your
.heicfiles, or click to browse. - Arrange the order — it becomes the page order.
- Click Convert, then Download.
If your browser cannot open HEIC
If the images fail to load, you are likely on Firefox or an older browser. Two options:
- Open the same page in Safari, Chrome or Edge, then convert as normal.
- Or export the photos as JPG first: on iPhone, Settings → Camera → Formats → Most Compatible makes new photos save as JPG; existing photos can be shared as JPG from the Photos app.
Caveats
- HEIC is already compressed. The tool decodes the photo and embeds it losslessly, so there is no extra visible loss — but it cannot add detail that the original HEIC did not contain.
- Live Photos and bursts export as single still images, not video.
- Large batches of 48MP photos can be heavy; convert in groups if your device slows down.
Is it private?
Yes. The photos are decoded and embedded into the PDF inside your browser. Nothing is uploaded, no account is created, and no copies are stored anywhere.
Frequently Asked Questions
Why won't my HEIC photos open in Firefox?+
Firefox does not include a HEIC decoder. Open this page in Safari, Chrome or Edge instead, or export the photos as JPG first.
Can I convert many HEIC photos into one PDF?+
Yes. Drop them all at once — each photo becomes one page, in the order you added them.
Does converting HEIC to PDF lose quality?+
No extra loss. HEIC is already a compressed format; the tool decodes it and embeds it losslessly, so the PDF looks the same as the photo on your phone.
Do I need to install an app or plug in my iPhone?+
No. Transfer the files however you like (AirDrop, iCloud, cable), then convert them in the browser. No app, no account, no plugin.
Where are HEIC files stored on an iPhone?+
In the Photos app. To get the actual files, use AirDrop to a Mac or PC, or open Files → On My iPhone. iCloud Photos can also download originals.
