Generation loss — quality may degrade
HEIC uses lossy compression, and so does HEIF. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Default format on iPhone 7+ (iOS 11+)
Your device saves files in HEIC by default (iPhone 7+ (iOS 11+), iPad Pro 2017+, macOS High Sierra+). Most people convert because the files won't open on other devices — HEIF is universally supported and will work everywhere.
What compression artifacts to expect
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

About HEIC to HEIF Conversion
Whether you're one of the many photographers, designers, and content creators who work with HEIC files daily, there comes a time when you need HEIF instead. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG.
Here's a typical scenario: you receive a .heic file but your project, platform, or client requires .heif. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices. Rather than searching for desktop software or wrestling with command-line tools, you can convert HEIC to HEIF online in seconds with CocoConvert.
This conversion is ideal when you Your HEIC file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts HEIF uploads. The conversion helps you improve file compatibility across devices.
HEIC uses lossy compression, and so does HEIF. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. Common misconception: ""I'll convert to HEIF and then back to HEIC — it'll be the same"" — in reality, each lossy conversion cycle permanently degrades quality. going heic → heif → heic will produce a noticeably worse file than the original. always keep your source file.
Behind the scenes, CocoConvert uses industry-standard tools — FFmpeg for audio and video, Sharp for images, qpdf for documents. Your file is uploaded securely (TLS encryption), processed on isolated servers in Germany, and auto-deleted within 24 hours. No account, no watermark, no hidden fees.
Power users can batch convert up to 100 files simultaneously with a Pro subscription, making it practical for production workflows.

What Happens When You Convert HEIC to HEIF
Your HEIC image is decoded into raw pixel data, then re-encoded as HEIF. Quality degrades each time lossy data is re-encoded. Convert from the original source when possible.
Your HEIC file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using High Efficiency Image Format's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIF supports it
The HEIF file is saved and ready for download

Should You Convert HEIC to HEIF?
When to Convert
- ✓Your HEIC file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts HEIF uploads
- ✓You captured this file on iPhone 7+ (iOS 11+) and need to share it with others
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
Common Mistakes When Converting HEIC to HEIF
"I'll convert to HEIF and then back to HEIC — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going HEIC → HEIF → HEIC will produce a noticeably worse file than the original. Always keep your source file.
