Convert, compress, and edit PDFs instantly in your browser.
If you've ever tried to share a photo from your iPhone and the recipient couldn't open it, there's a good chance it was a HEIC file. Apple uses HEIC as its default camera ssbecause it saves storage space — but it isn't universally supported outside Apple devices.
Converting HEIC to PDF is the fastest way to make your photos shareable, printable, and easy to open on any device — Windows, Android, or the web.
If you want the fastest option in your browser, use iConvertOnline HEIC to PDF.
What is a HEIC file?
HEIC (High Efficiency Image Container) is Apple's default camera format, introduced with iOS 11. It delivers better image quality at roughly half the file size of JPG. The problem is that Windows support can vary unless the right extensions are installed, and many web platforms, email clients, and document tools don't recognise it either.
Converting to PDF solves this instantly — PDFs open on every device, every operating system, and every browser without needing any special software.
Why convert HEIC to PDF instead of JPG?
JPG is fine for a single photo. But PDF makes more sense when:
You're sharing multiple photos at once: One PDF keeps everything together instead of a folder of loose image files.
You need to print: PDF preserves layout and margins better than JPG.
You're submitting documents: Insurance claims, rental applications, and compliance uploads almost always prefer PDF.
You want to protect the image: PDFs are harder to accidentally edit than image files.

Try it freeTip: If you're converting multiple HEIC photos into one PDF, check the page order before downloading. The tool arranges them in upload order, so name your files 01-, 02-, 03- if sequence matters.
Common mistakes to avoid
Skipping the page order check: If sequence matters — for a claim, application, or report — rename your files 01-, 02-, 03- before uploading so the order is obvious.
Ignoring file size after converting: Multiple high-res HEIC photos can produce a large PDF. If you hit an upload limit, run it through Compress PDF before submitting.
What if my HEIC file won't upload?
A few common reasons this happens:
File is too large: Try converting one file at a time, or compress the image first.
Wrong file extension: Some HEIC files are saved as .heif — these are the same format and should still convert correctly.
Corrupted file: If the photo won't open on your iPhone either, the file itself may be damaged.
Can I convert iPhone HEIC photos to PDF on mobile?
Yes. Open the HEIC photo in your Photos app, tap Share, and select Print. From the print preview, pinch outward on the preview thumbnail — this converts it to a PDF you can save or share. It's a bit hidden, but it works without any third-party app.
Alternatively, use iConvertOnline HEIC to PDF in your mobile browser — it works just as well on iPhone as on desktop.
Real-world reasons people convert HEIC to PDF
Rental applications: Landlords and agencies often request ID, payslips, and photos as a single PDF.
Insurance claims: Submit photo evidence of damage alongside claim forms in one file.
Medical records: Share scan photos with clinics that only accept PDF uploads.
School submissions: Convert assignment photos taken on iPhone into a submittable PDF.
