Q: Can I convert HEIC to other formats?

Yes! Use our free tools: HEIC to PNG , HEIC to JPG , or HEIC to WebP . All conversions happen in your browser.

If you've transferred photos from an iPhone to a Windows PC, you've probably encountered .heic files that won't open. Here's everything you need to know about this format and how to deal with it.

HEIC Explained

HEIC stands for High Efficiency Image Container. It's a file format based on the HEIF (High Efficiency Image Format) standard, using HEVC (H.265) video compression technology to encode still images.

In simpler terms: HEIC is a modern image format that produces much smaller files than JPEG while maintaining equal or better image quality. Apple made it the default photo format on iPhones and iPads starting with iOS 11 in September 2017.

Key Features of HEIC

50% smaller than JPEG at the same visual quality
16-bit color depth for richer colors and better HDR support
Transparency support (alpha channel), unlike JPEG
Multiple images in a single file (used for Live Photos, burst sequences)
Non-destructive editing — edits are stored as instructions, preserving the original
EXIF metadata support for camera settings, GPS, dates

Why It's a Problem

Despite its technical advantages, HEIC isn't universally supported:

Windows requires a paid extension ($0.99) for full support
Web browsers have limited support (Safari works, Chrome doesn't natively)
Social media and many websites don't accept HEIC uploads
Older software can't open HEIC at all
Email attachments may not display for recipients without HEIC support

How to Convert HEIC Files

The easiest solution for HEIC compatibility issues is to convert to a universal format. Our free online tools handle this instantly:

HEIC to PNG — lossless quality, universal support
HEIC to JPG — smaller files, maximum compatibility
HEIC to WebP — modern format, best compression

All conversions happen in your browser — your photos are never uploaded to any server.

How to Stop iPhone from Saving HEIC

If you'd rather avoid HEIC entirely, change your iPhone camera settings:

Open Settings → Camera → Formats
Select Most Compatible (saves as JPEG instead of HEIC)

Note: This roughly doubles the storage space your photos use.

Frequently Asked Questions

Why does my iPhone save photos as HEIC?

Apple adopted HEIC as the default format in iOS 11 (2017) because it produces files about 50% smaller than JPEG at equivalent quality. This saves significant storage space on your device and iCloud.

How do I open HEIC files on Windows?

Install the free HEIF Image Extensions from the Microsoft Store. You may also need the HEVC Video Extensions ($0.99). Alternatively, convert to PNG or JPG for instant compatibility.

How do I open HEIC files on Android?

Most modern Android phones (Android 10+) can open HEIC files natively. For older versions, use Google Photos or convert to JPG/PNG.

Is HEIC the same as HEIF?

Nearly. HEIF (High Efficiency Image Format) is the container standard; HEIC is a specific variant that uses HEVC compression. Apple uses the .heic extension for HEIF files encoded with HEVC. In practice, they're used interchangeably.

Can I convert HEIC to other formats?

Yes! Use our free tools: HEIC to PNG, HEIC to JPG, or HEIC to WebP. All conversions happen in your browser.
