Need help?How to Convert HEVC to AVIF
- Upload your HEVC video — Click "+ Add Files" or drag and drop your HEVC (H.265) video files. Batch upload is supported.
- Choose frame extraction mode — Under "Frame Selection," pick "Specific Frame" and enter a timestamp in seconds (e.g., 2.5 for 2 seconds and 500ms into the video), or choose "Multiple Screenshots" to extract frames at a set rate (every 0.1s up to every 10s).
- Adjust image 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 video resolution, scale by percentage (1–100%), pick a preset (4320p down to 144p), or enter exact width/height.
- Convert and download — Click "Convert" and download your AVIF images.
Why Convert HEVC to AVIF?
HEVC (H.265) is the leading video codec for 4K and HDR content, offering 50% better compression than H.264. AVIF is the image counterpart — developed by the Alliance for Open Media using AV1 compression technology, it delivers the smallest image files at any given quality level. Extracting frames from HEVC video as AVIF gives you the best of both worlds: you capture stills from high-quality video and save them in the most efficient image format available.
This conversion is particularly useful for creating thumbnails from 4K video, extracting key frames for video previews on websites, or pulling still images from drone footage, security cameras, or screen recordings encoded in HEVC. AVIF's superior compression means these extracted frames load faster on web pages than equivalent JPEG or PNG files.
HEVC Frame Extraction to AVIF vs Other Formats
| Output Format | Compression | Transparency | Typical 1080p Frame | Best For |
|---|---|---|---|---|
| AVIF | Best (AV1-based) | Yes | ~60–100 KB | Web thumbnails, modern browsers |
| WebP | Very good | Yes | ~80–140 KB | Broad browser support |
| JPEG | Good (lossy) | No | ~150–300 KB | Universal compatibility |
| PNG | Lossless only | Yes | ~2–5 MB | Pixel-perfect screenshots |
Frequently Asked Questions
What is HEVC?
HEVC (High Efficiency Video Coding), also known as H.265, is a video compression standard that succeeds H.264. It can store video at the same quality with up to 50% less data, making it the standard codec for 4K, 8K, and HDR content on streaming platforms, cameras, and mobile devices.
Can I extract multiple frames at once?
Yes. Under "Frame Selection," choose "Multiple Screenshots" and set a capture rate — from every 0.1 seconds (10 FPS) to every 10 seconds. This generates a batch of AVIF images from your video, useful for creating image sequences or selecting the best frame later.
What quality setting should I use?
"Very High (Recommended)" preserves excellent detail for most use cases. For web thumbnails where file size matters more, try "High" or "Medium." The "Image Quality (%)" slider gives fine-grained control — 80% is a good balance, 95%+ is near-lossless.
Is AVIF supported in all browsers?
AVIF is supported in Chrome, Firefox, Safari (16.4+), Edge, and Opera — over 95% of web users as of 2026. For older browser support, consider extracting frames as JPEG or WebP instead.
Can I extract a frame at a specific timestamp?
Yes. Under "Frame Selection," choose "Specific Frame" and enter the exact time in seconds. For example, entering 5.0 captures the frame at exactly 5 seconds into the video. Decimal values are supported for sub-second precision (e.g., 2.100 = 2 seconds and 100 milliseconds).
