iPhone photos saved as HEIC files that won't open on Windows or Android? Learn how to convert HEIC to JPG instantly for free — entirely in your browser, no upload, no app download, and no quality loss.
You took hundreds of photos on your iPhone. Now you're trying to send them on WhatsApp, upload them to a government form, share them with a Windows user, or post them on a website — and nothing works. The files end up as grey boxes or "unsupported format" errors.
The culprit is HEIC — Apple's proprietary image format. And the fix is simple: convert them to JPG. In this guide, we show you the fastest, most private way to do it for free using the MojoDocs Image Converter.
What is HEIC and Why Does iPhone Use It?
HEIC stands for High Efficiency Image Container — it's Apple's implementation of the HEIF image standard, introduced with iOS 11 in 2017. Apple switched to HEIC because it delivers:
- 50% smaller file size than JPG at equivalent visual quality.
- Better HDR and depth data storage for Portrait mode photos.
- Live Photo encoding in a single file container.
In simple terms: HEIC photos look identical to JPG but take up half the storage space on your iPhone. That's excellent for Apple users. But it creates a nightmare the moment you try to use those photos anywhere outside Apple's ecosystem.
Why HEIC Files Don't Open Everywhere
| Platform / Use Case | HEIC Support | Notes |
|---|---|---|
| Windows 10/11 | ~ Partial | Requires paid HEVC Video Extensions from Microsoft Store (~₹250) |
| Android Phones | ✗ No support | Most Android gallery apps cannot open HEIC files at all |
| WhatsApp / Telegram | ✗ No | Will not send HEIC — shows error or sends as unviewable file |
| Government / Bank forms | ✗ No | Almost all portals only accept JPG or PNG |
| WordPress / Webflow | ✗ No | CMS platforms reject HEIC uploads |
| Mac / iPhone / iPad | ✓ Full support | Apple devices open HEIC natively — no conversion needed within Apple ecosystem |
How to Convert HEIC to JPG on MojoDocs (Step by Step)
The MojoDocs Image Converter handles HEIC conversion entirely in your browser. No upload, no signup, no limit.
- Go to mojodocs.in/image/image-converter — no account or download needed.
- Drop your HEIC files into the drop zone. You can select multiple files at once for batch conversion.
- Choose JPG as the output format from the format dropdown. You can also choose PNG, WebP, or AVIF.
- Adjust quality if needed (80% is the sweet spot — looks identical to full quality but smaller file size).
- Click Convert and download. Your JPGs are ready. All processing happened locally on your device.
Privacy Note
Your iPhone photos often contain sensitive EXIF metadata: GPS location where the photo was taken, the exact time, your device model. When you upload HEIC files to online converters that use servers, this data travels to a third party. MojoDocs processes everything locally — your photos and their embedded location data never leave your browser.
HEIC to JPG: Quality Comparison
Many people worry that converting HEIC to JPG will degrade quality. Here's the reality:
- At 90–100% JPG quality: The output is visually indistinguishable from the original HEIC. File size will be slightly larger than HEIC (this is normal — JPG is less efficient).
- At 75–85% JPG quality: Excellent quality for WhatsApp, social media, or web use. File size is comparable to the original HEIC.
- At 60–70% JPG quality: Slight compression visible on close inspection, but fine for thumbnails, form uploads, or email attachments.
For government form uploads (where file size limits are strict, like 100KB), set quality to 65–70% and the HEIC portrait photo will compress down to the required size while remaining clear and legible.
Alternative: Change iPhone Settings to Save as JPG
If you regularly need JPG files and don't want to convert every time, you can change your iPhone to save photos in JPG format instead of HEIC:
- Open Settings on your iPhone.
- Scroll down and tap Camera.
- Tap Formats.
- Select Most Compatible (instead of "High Efficiency").
From now on, your iPhone will save new photos as JPG. Note: this does not convert your existing HEIC photos — you'll still need MojoDocs for those.
Sending HEIC Photos from iPhone Without Converting
When you AirDrop photos to another iPhone, or share via iCloud Photos, HEIC works fine. The problem only occurs when sharing with non-Apple devices or uploading to websites. In those cases, use MojoDocs to convert first.
Batch Convert Hundreds of HEIC Files
If you've been shooting in HEIC for years and need to convert your entire photo library, MojoDocs supports unlimited batch conversion. Drop all your HEIC files at once, set JPG as output, and convert them all in a single operation — all locally, without any rate limits or file count restrictions.
Other Converters: Why Not Use Them?
- iMazing HEIC Converter (Desktop app): Free but requires a Windows/Mac app download. Not available on mobile.
- HEICtoJPEG.com / FreeConvert.com: Upload your photos to their server. Your iPhone photos — with embedded GPS data — travel to a third-party server. Privacy risk.
- Windows HEVC Extension: Paid (₹250), only works on Windows, and only for viewing — not bulk converting.
- MojoDocs: Free, browser-based, works on any device (Mac, Windows, Android, iPhone), no upload, no limit.
