- Choose a Quality Preset — Select from Highest, Very High (Recommended), High, Medium, Low, Very Low, or Lowest.

Why Convert AVIF to AV1 Video?
AVIF and AV1 share the same underlying codec — AVIF is the still image format based on AV1 video compression. Converting AVIF images to AV1 video creates animated content, slideshows, and timelapses using the most efficient video codec available. AV1 delivers roughly 50% better compression than H.264 and 30% better than H.265, making it ideal for web streaming where bandwidth matters.
AVIF vs AV1
| Feature | AVIF (image) | AV1 (video output) |
|---|---|---|
| Underlying codec | AV1 (still frame) | AV1 (video stream) |
| Type | Still image | Video |
| Animation | ❌ (single frame) | ✅ |
| Multiple images | Separate files | ✅ Merged into one video |
| Web streaming | N/A | ✅ (YouTube, Netflix, etc.) |
| Compression | Best for images | Best for video |
| Browser support | ~93% | ~93% |
Use Cases
- Web video content — Create AV1 videos from AVIF images for maximum compression efficiency on web platforms that support AV1 (YouTube, Netflix, Twitch).
- Timelapse — Assemble a sequence of AVIF photos into an AV1 timelapse at 1/24s or 1/30s per frame for the smallest possible file size.
- Photo slideshows — Combine AVIF photos into an AV1 slideshow with 3–5 seconds per image for bandwidth-efficient delivery.
- Codec consistency — Since AVIF uses AV1 compression for images, converting to AV1 video keeps the entire pipeline in the same codec family.
What is the relationship between AVIF and AV1?
AVIF (AV1 Image File Format) uses the AV1 video codec to compress still images. Converting AVIF to AV1 video essentially takes still frames compressed with AV1 and packages them into a video stream using the same codec.
How long will each image display?
You control this with the Image Duration setting. Options range from 1/60s (a single frame) to 10 seconds per image.
Can I merge multiple AVIF images into one video?
Yes. Select "Merge images" under Merge Strategy. All uploaded AVIF files are combined into a single AV1 video in upload order.
Is AV1 widely supported?
AV1 is supported by Chrome, Firefox, Edge, Safari 17+, YouTube, Netflix, and most modern streaming platforms. Hardware decoding is available on newer GPUs and mobile chips.
Can I set a background color?
Yes. Under Background Color, choose from Black (default), White, and other colors. This fills the space around images that don't match the output resolution.
