- Mobile-friendly UI — works on iPhone, Android, Windows, and Mac.
What is a HEIC file?
HEIC (High Efficiency Image Container) is Apple’s image format that uses HEIF/HEVC compression. It saves storage space while preserving quality, but older tools and many websites still expect JPG.
- HEIC ~ HEIF container with HEVC-encoded images.
- Supports multiple images (Live Photos), alpha channels, and advanced metadata.
- Not universally supported — converting to JPG ensures wide compatibility.
Does converting HEIC to JPG reduce quality?
Converting from HEIC to JPG can be lossy depending on the chosen quality setting. Our tool lets you pick quality and output size to balance file size and image fidelity.
- Original HEIC: 3.2MB
- Converted JPG (High, 0.95): 2.9MB — visually identical in most cases
- Converted JPG (Normal, 0.80): 1.3MB — good quality and much smaller
Will EXIF metadata be preserved?
We preserve most EXIF metadata where possible. Some format conversions may strip non-standard or complex metadata (e.g., some proprietary Live Photo fields). If you need guaranteed metadata preservation, download converted files immediately and check with your preferred EXIF tool.
Batch conversion & ZIP download — limits & tips
The tool supports batch conversions; however, browser and device memory limit the practical size. For best results:
- Recommended batch size: up to 50 images for typical phones.
- For very large batches, convert in smaller chunks and create multiple ZIPs.
- Use the Original preset for lossless output when you only need container change.
How to convert HEIC online (3 steps)
- Add your HEIC images using the "Add Images" button or drag-and-drop.
- Choose output format (JPG/PNG/WebP), output size, and quality.
- Click Convert and download each file or click "Download ZIP" for all results.
Troubleshooting & mobile tips
Common issues and fixes:
- Files won’t open: Check that the file extension is .heic; try renaming lower-case. If iOS exported images as .heic.zip, extract first.
- Slow conversion: Use smaller batch sizes or switch to a higher-performance device. Close other browser tabs to free memory.
- EXIF missing: Some metadata may not survive format conversion — export with Original preset if metadata is critical.
- iPhone settings: On iPhone, go to Settings → Camera → Formats → keep "Most Compatible" off to keep .heic, or on to capture directly as JPG.
