HEIC Image Conversion: Batch Convert, Resize & Organize
High Efficiency Image Container (HEIC) is a modern image format developed by MPEG. It uses HEVC (H.265) compression and is the default photo format on iPhones and iPads running iOS 11 and later. HEIC files can also store image sequences, depth maps, and HDR data.
Contenta Converter PREMIUM lets you open, convert, and batch process HEIC files into modern formats like JPG, PNG, TIFF, PDF, and more. Optimize file size, keep important metadata, and prepare images for web, print, or long-term archiving in just a few clicks.

| 說明 | High Efficiency Image Container (HEIC) is a modern image format developed by MPEG. It uses HEVC (H.265) compression and is the default photo format on iPhones and iPads running iOS 11 and later. HEIC files can also store image sequences, depth maps, and HDR data. | 差不多所有數碼相機都會有把圖像保存為JPEG的選項。JPEG格式支持每色8位（紅，綠，藍），文件大小也比較小。只要不使用重度壓縮，圖像質量不會受太大的影響。不過JPEG文件如果不斷被修改，保存的話，很有可能會退化。若您計劃以後修改照片圖像，或不能接受圖像失真，把它們保存為非JPEG的無損圖像格式的話會比較好。話雖如此，JPEG大致上是最適合網絡發佈的格式。 |
| 優點 | Approximately 50% smaller file size than JPEG at equivalent visual quality. Supports 16-bit color depth, transparency, and image sequences. Preserves Live Photo data on Apple devices. | 小的文件大小，非常受歡迎 |
| 缺點 | Limited native support on Windows (requires HEVC codec from Microsoft Store) and older Android devices. Not universally accepted by web browsers, email clients, or social media upload forms. | 質量損失 |
| 相機 | Apple iPhone 7 and later, Apple iPad Pro, iPad Air, iPad mini (2017+), Samsung Galaxy S21+, Samsung Galaxy S22+, Samsung Galaxy S23+, Samsung Galaxy S24+, Google Pixel 6+ | |
| 元數據 | Full EXIF and XMP metadata including GPS, camera settings, depth map, and HDR gain map. Apple-specific properties like Live Photo motion data are embedded. | 處理XMP, EXIF 或 IPTC |

Frequently Asked Questions about HEIC
What is a HEIC image file?
A HEIC file is a type of image format used in various tools and workflows. With Contenta Converter PREMIUM you can convert HEIC files to more common formats like JPG, PNG, or PDF without losing control over quality.
How do I convert HEIC images to JPG?
Install Contenta Converter PREMIUM, add your HEIC files to the input list, choose JPG as the output format, and click Convert. The software will process all selected files in a single batch.
Can I batch-process many HEIC images at once?
Yes. Contenta Converter PREMIUM is built for batch processing and can handle hundreds or thousands of HEIC images in one operation, using all available CPU cores.
When should I convert HEIC images to another format?
Convert HEIC images when you need better compatibility with web browsers, design tools, or printing services. Exporting to formats like JPG, PNG, or TIFF from Contenta Converter PREMIUM makes sharing and archiving much easier.
Why are my iPhone photos in HEIC format?
Starting with iOS 11, Apple set HEIC as the default photo format because it produces files roughly 50% smaller than JPEG at the same quality. You can change this in Settings > Camera > Formats, choosing Most Compatible for JPEG instead.
Can I convert HEIC to JPG without losing quality?
Yes. Contenta Converter PREMIUM converts HEIC to JPG with adjustable quality settings (up to 100%). At quality 95-100%, the visual difference is imperceptible. The software also preserves EXIF metadata during conversion.
Can Windows open HEIC files natively?
Windows 10/11 can display HEIC files after installing the free HEIF Image Extensions and the paid HEVC Video Extensions from the Microsoft Store. For batch conversion without codec hassles, Contenta Converter PREMIUM handles HEIC natively.
