Need help?How to Convert MP4 to HEIF
- Upload your MP4 video — Click "+ Add Files" or drag and drop your MP4 or M4V files.
- Choose frame extraction — Under "Frame Selection," pick "Specific Frame" and enter a timestamp in seconds, or choose "Multiple Screenshots" to extract frames at intervals from every 0.1 seconds to every 10 seconds.
- Adjust quality — Under "Image Compression," select "Quality Preset" (Highest to Lowest), "Specific file size" in KB/MB with Smart Scaling, or "Image Quality (%)" with a 1–100 slider.
- Set resolution — Keep original, scale by percentage (1–100%), pick a preset (4320p to 144p), or enter exact width/height.
- Convert and download — Click "Convert" and download your HEIF images.
Why Convert MP4 to HEIF?
HEIF (High Efficiency Image Format) uses HEVC compression to produce images roughly half the size of JPEG at equivalent quality, with support for 10-bit color depth. Extracting frames from MP4 video as HEIF gives you the most storage-efficient still images — ideal for Apple device users where HEIF is natively supported since iOS 11.
This is useful for creating thumbnails from video content, extracting key frames for social media, or pulling still photos from iPhone recordings where HEIF matches the native photo format.
HEIF vs Other Frame Extraction Formats
| Format | Compression | Typical 1080p Frame | Color Depth | Apple Native |
|---|---|---|---|---|
| HEIF | HEVC | 80–150 KB | 10-bit | Yes (iOS 11+) |
| AVIF | AV1 | 60–100 KB | 10-bit | Safari 16.4+ |
| JPEG | DCT | 150–300 KB | 8-bit | Universal |
| PNG | Lossless | 2–5 MB | 8/16-bit | Universal |
Frequently Asked Questions
Can I extract a frame at a specific timestamp?
Yes. Choose "Specific Frame" and enter the time in seconds. Decimal values work — 3.5 captures the frame at 3 seconds and 500 milliseconds.
Can I batch-extract multiple frames?
Yes. Choose "Multiple Screenshots" and set the capture rate from every 0.1 seconds (10 FPS) to every 10 seconds.
What's the difference between HEIF and HEIC?
HEIF is the format standard; HEIC is a specific file type within it that uses HEVC compression. In practice they're used interchangeably — Apple devices save photos as .heic files within the HEIF standard.
Will HEIF files open on Windows?
Windows 11 supports HEIF natively. Windows 10 requires the free "HEIF Image Extensions" from the Microsoft Store. For universal compatibility, extract as JPEG instead.
Can I also upload M4V files?
Yes. This tool accepts both MP4 and M4V files — M4V is Apple's variant of the MP4 container.
