Convert HDR to AVIF
Fast, free, and secure HDR to AVIF conversion. No registration required.
Ready to switch from hdr to avif? Drag your files into the converter and download the results immediately. HDR Image is best described as radiance hdr format for high dynamic range lighting data, primarily serving HDR photography, 3D lighting environments and tone mapping. AVIF Image takes over where HDR Image falls short: smallest file sizes of any image format at equivalent quality, royalty-free. This conversion bridges two ecosystems: Greg Ward's HDR Image and Alliance for Open Media's AVIF Image. No ads interrupt your conversion flow — Xonvert keeps the experience clean and distraction-free.
Why Choose AVIF Format for Your HDR Files?
There are strong reasons to convert HDR to AVIF:
Quality preservation: Converting from HDR Image to AVIF Image maintains excellent visual quality while reducing size.
Hardware acceleration: AVIF Image benefits from hardware-accelerated decoding on most modern devices, ensuring smooth playback and rendering.
Web optimization: AVIF Image is better suited for web delivery, loading faster and using less bandwidth than HDR Image.
Streaming support: AVIF Image is well-suited for streaming and progressive loading, making it ideal for web and mobile delivery.
Platform requirements: Many platforms and services specifically require AVIF Image format, making this conversion essential for submissions and uploads.

Conversion Quality Deep Dive
File size after conversion depends on the content complexity and your quality settings. AVIF Image's compression algorithm is highly efficient — expect output sizes 2-10x smaller than uncompressed data. Use AVIF with WebP and JPEG fallbacks in picture elements For the best results, start with the highest quality HDR Image source file available. AVIF Image is known for smallest file sizes of any image format at equivalent quality, royalty-free. This means your converted output will benefit from AVIF Image's core strengths. Meanwhile, the original HDR Image's advantage of captures extreme brightness ranges for realistic lighting may not fully carry over, depending on AVIF Image's capabilities.
Converting between image formats is one of the most common file operations. When moving from HDR Image to AVIF Image, key considerations include color depth preservation, transparency support, and compression artifacts. Moving from lossless HDR Image to lossy AVIF Image will reduce file size significantly, potentially by 50-90%. Some fine detail may be simplified during compression, but at Xonvert's default quality settings the difference is virtually imperceptible to the human eye.
Transparency: AVIF supports transparency channels. Since HDR does not contain transparency data, the output will have a fully opaque alpha channel.
Compression trade-off: Your lossless HDR source retains all original data. Converting to lossy AVIF will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.

Common Questions About HDR to AVIF
How long does HDR to AVIF conversion take?▼
Most files convert in under 5 seconds. Larger files may take 10-30 seconds depending on your device's processing speed.
Can I convert HDR to AVIF in bulk for free?▼
Yes. Free users can batch-convert multiple files. Simply drag all your HDR files into the converter at once. PRO users get higher batch limits and priority processing.
What's the difference between HDR and AVIF?▼
HDR Image is radiance hdr format for high dynamic range lighting data. AVIF Image is next-generation format based on av1 video codec offering best-in-class compression. Key difference: HDR Image excels at captures extreme brightness ranges for realistic lighting, while AVIF Image offers smallest file sizes of any image format at equivalent quality, royalty-free.
How does the HDR to AVIF conversion work technically?▼
Xonvert uses WebAssembly-compiled libraries to decode your HDR file in-browser, process the image data, and re-encode it as AVIF. All processing happens on your device's CPU.
What happens to my files after conversion?▼
Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.
What is HDR format?▼
HDR Image is Radiance HDR format for high dynamic range lighting data. It is primarily used for HDR photography, 3D lighting environments and tone mapping. Stores luminance data in RGBE (RGB + exponent) encoding
Will the conversion strip my EXIF or metadata?▼
Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target AVIF format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.
