Why HEIC Causes Upload Errors on iPhone
Apps and sites reject .heic uploads
Many web forms, ticketing systems, and non-Apple apps simply don't accept HEIC. Converting to PNG is the quickest fix.
Settings → Most Compatible only helps future shots
Camera → Formats → Most Compatible only changes how future photos are saved. HEIC photos already in your Camera Roll stay HEIC.
iMessage and AirDrop handle HEIC, the open web doesn't
HEIC works fine Apple-to-Apple, but the moment you leave the Apple ecosystem — email, Slack, a web form — you run into trouble.

Frequently Asked Questions
1
Can I stop my iPhone from saving HEIC entirely?
Yes — Settings → Camera → Formats → Most Compatible switches future photos to JPG. This does not convert photos already in your library; you still need a converter for those.
2
How do I convert old HEIC photos already on my iPhone?
Open Safari to heictopng.org, tap upload, pick photos from your Camera Roll, and save the PNGs to Photos or Files. Nothing uploads to a server — the conversion runs locally in Safari.
3
Does this work on iOS 15, 16, 17, and 18?
Yes. Any iPhone running iOS 15 or later supports the Web APIs this converter uses. iOS 18 is fully supported.
4
Will converted PNGs keep Portrait mode or Live Photo data?
PNG is a flat image format and does not store depth maps or Live Photo video. The visible photo is preserved at full resolution; the interactive layers are flattened.
5
How do I send a converted PNG via iMessage or WhatsApp?
After tapping Download, save to Photos or Files. Then in iMessage/WhatsApp tap the attach button and pick the PNG you just saved.
6
Is it safe to convert personal photos on this site?
Yes. Conversion runs entirely in Safari on your iPhone. Your photos never leave the device. Once you close the tab, nothing is stored anywhere.
7
Should I change Settings → Most Compatible or convert the existing photos?
Do both. Most Compatible only affects future shots — it will not touch the HEIC photos already in your Camera Roll. If you need PNGs for old photos (emailing to a friend, uploading to a site that rejects HEIC), run them through heictopng.org in Safari. To stop accumulating more HEIC files going forward, flip the Settings toggle too. One solves today's problem; the other prevents tomorrow's.
8
Where do the downloaded PNGs end up on my iPhone?
When you tap Download in Safari, iOS asks whether to save to Photos or Files. Photos is easiest for later sharing via iMessage, WhatsApp, or Instagram (those apps pick from your Camera Roll). Files is better if you want the PNG organized in a specific folder, AirDrop it to a Mac, or attach it from an email app that reads from Files. You can move between the two after download.
9
Will the converted PNGs sync through iCloud Photos to my Mac?
Yes, if you saved to Photos and have iCloud Photos enabled on both devices. The PNG appears in the camera roll on your Mac, iPad, and any other signed-in device within a few seconds to minutes. This is the easiest way to bulk-convert on iPhone and then edit on a larger screen. If you saved to Files instead, only items stored in iCloud Drive sync — Photos on other devices will not show them.
