You take a photo on your iPhone and email it. The recipient on Windows or Android replies: "I can't open this file." HEIC attachments are the most common reason this happens. While newer Apple devices handle HEIC fine, most Windows email clients, Android mail apps, and older Mac users cannot open .heic attachments.
The fix: convert to PNG before you send. WildandFree's HEIC to PNG converter takes under a minute. The recipient gets a file they can open on any device — and you get lossless quality with no recompression.
Why HEIC Files Don't Open for Email Recipients
When you email a photo from your iPhone, iOS sends the file in its original format — HEIC. The email arrives at the recipient's inbox as a .heic attachment. Whether they can open it depends entirely on their device and email setup:
- Windows + Outlook: Outlook on Windows cannot open HEIC thumbnails or attachments without the Microsoft HEIF extensions. Most Windows users have not installed this codec.
- Android email clients: Gmail for Android, Outlook for Android, and Samsung Email cannot display HEIC inline or open the attachment in the gallery.
- Older Macs: macOS before High Sierra (2017) cannot open HEIC. Older iMacs and MacBooks running Sierra or earlier will fail.
- Web email (Gmail, Outlook.com): Gmail's web client cannot display HEIC inline. The recipient sees a download link but may still be unable to open it once downloaded.
The safest approach for any email containing photos that need to be viewed by the recipient: convert to PNG (lossless) or JPG (smaller file) before attaching.
Should You Email PNG or JPG? (Converting from HEIC)
Both PNG and JPG are universally supported in email clients. The choice depends on your use case:
| Scenario | Best Format | Why |
|---|---|---|
| Sharing personal photos | JPG | Smaller file — faster to download on mobile |
| Sending to a designer or printer | PNG | Lossless — no quality loss for editing or print |
| Attaching a screenshot | PNG | Text stays sharp; JPG blurs text edges |
| Sending multiple photos | JPG | Smaller file sizes reduce email size limits |
| Photos for documentation | PNG | Pixel-accurate — good for reference and archiving |
| Casual sharing, fast viewing | JPG | Recipients see inline previews faster |
For most personal and business photo emails, JPG is the practical choice. Use PNG when quality and accuracy matter more than file size — design work, documentation, printed materials.
The HEIC to PNG converter gives you lossless PNG output. If you need JPG specifically, use the HEIC to JPG converter instead.

The fastest workflow:
- Get the HEIC file on your computer. AirDrop to Mac, cable transfer to PC, or save from iCloud. The photo will be a .heic file.
- Open the converter. Go to wildandfreetools.com/converter-tools/heic-to-png/ in Chrome, Safari, or Edge.
- Drop the file(s) and convert. Multiple photos for one email? Drop them all at once.
- Download the PNG files. They land in your Downloads folder.
- Attach to your email. Use the PNG files as attachments. Your recipient sees a universally-compatible image file.
The whole process takes about 90 seconds. For a batch of 5–10 photos, under 3 minutes.
iPhone tip: If you're emailing directly from your iPhone, iOS automatically converts HEIC to JPG when you share via email. Tap "Share" → "Mail" and iOS handles the conversion for you. This guide is for when you need to email from a desktop or need PNG specifically.
Permanently Prevent HEIC Email Problems — Change Your iPhone's Camera Format
If you frequently email photos from your iPhone and constantly deal with compatibility issues, changing your iPhone's camera format to JPG prevents the problem at the source:
- Open Settings on your iPhone.
- Tap Camera.
- Tap Formats.
- Select Most Compatible (instead of High Efficiency).
Your iPhone will now shoot in JPG. Photos are slightly larger on your device but fully compatible with every email client and device. The trade-off: you lose the ~50% storage efficiency of HEIC.
If storage matters, keep HEIC on (High Efficiency) and convert selectively when you need to send photos by email. The converter handles this in under a minute per batch.

Open Free HEIC to PNG ConverterFrequently Asked Questions
Why can't my email recipient open the iPhone photo I sent?
Your iPhone sent the photo as a HEIC file. HEIC is not supported by most Windows email clients, Android email apps, or older Macs. Convert to PNG or JPG before attaching, and every email client will be able to open it.
How do I convert iPhone photos to PNG for email?
Transfer the HEIC photo to your computer, go to wildandfreetools.com/converter-tools/heic-to-png/ in your browser, drop the file, and download the PNG. The whole process takes under 2 minutes. Attach the PNG file to your email instead of the HEIC.
Does iOS automatically convert HEIC when emailing from an iPhone?
Yes, when you share a photo via the iOS Mail app, iOS converts HEIC to JPEG automatically. The conversion issue arises when you email photos from a computer after transferring them from your iPhone — in that case, they stay as HEIC and you need to convert manually.
Should I send PNG or JPG in email?
JPG for casual photo sharing — smaller files, faster loading in email previews. PNG when you need lossless quality for print, design, or documentation purposes. Both are universally supported by all email clients.
