Convert HEIC Photos to PDF — Straight from iPhone

Turn HEIC photos from an iPhone or iPad into a PDF — no need to convert them to JPG first. Drop them in, drag the pages into order, and get one document that opens on Windows, Android, and every website that refuses HEIC. Everything happens on your device; nothing is uploaded.

Two problems solved at once: HEIC will not open on most non-Apple systems, and a pile of loose photos is awkward to send. A PDF fixes both — universal compatibility and one file instead of many.

Why HEIC Causes Trouble

Since iOS 11, iPhones have saved photos as HEIC (High Efficiency Image Container). It is genuinely clever — roughly half the size of JPEG at the same quality, which is why Apple adopted it. The problem is everything else: Windows needs an extra codec, Android support is patchy, older software simply refuses, and a great many upload forms reject the format outright.

People usually discover this at the worst moment: uploading documents to an application portal, or emailing photos to someone who cannot open them.

Why PDF Rather Than JPG

Converting HEIC to JPG solves the compatibility problem but leaves you with a folder of separate files. A PDF goes further:

What Happens to the Image

PDF cannot store HEIC natively, so each photo is decoded in your browser and then embedded losslessly. Nothing is degraded in that second step, and the result is visually identical to what you see on your phone. Decoding does take a moment per photo — noticeably longer than JPG, because it runs in JavaScript rather than in hardware.

Common Uses

Frequently Asked Questions

How do I convert HEIC photos to PDF?

Drop your HEIC files straight in - no need to convert them to JPG first. They are decoded in your browser, and each becomes a page of a single PDF you can reorder before saving.

Why will my iPhone photos not open on Windows?

Because iPhones save in HEIC by default, a newer format that Windows, Android and many websites still cannot read. Putting the photos into a PDF sidesteps the problem entirely - a PDF opens on absolutely everything.

Do I have to convert HEIC to JPG first?

No. Many tools require that extra step; here HEIC is decoded directly. If you do want the JPGs as well, use the HEIC to JPG converter separately.

Is the photo quality preserved?

HEIC has to be decoded before it can go into a PDF, since PDF cannot store HEIC natively. It is then embedded losslessly, so nothing is lost at that stage. The result is visually identical to the photo on your phone.

Can I mix HEIC photos with JPGs and screenshots?

Yes. Add HEIC, JPG, PNG and other formats together and each becomes a page in the order you arrange them - useful when part of a document was photographed on a phone and part was screenshotted.

Why is HEIC conversion slower than JPG?

HEIC decoding runs in JavaScript in your browser rather than being handled natively, so each photo takes a moment. A large batch of iPhone photos will take noticeably longer than the same number of JPGs.

Does it work on an iPhone or iPad?

Yes. The page works in Safari and Chrome on iOS, so you can turn photos into a PDF on the phone that took them, without installing anything.

Are my photos uploaded anywhere?

No. Decoding and PDF assembly both happen on your device - which matters, because HEIC files are almost always personal photos.
