Color depth reduction: 32-bit → 12-bit

HDR stores up to 32 bits per channel, but AVIF supports only 12 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.

En la era digital actual, donde la calidad visual y la eficiencia son primordiales, la conversión de formatos de imagen se ha vuelto una tarea cotidiana. Si trabajas con imágenes de alto rango dinámico (HDR) y buscas optimizar su almacenamiento o distribución sin sacrificar la riqueza de detalles y el color, el formato AVIF emerge como una solución robusta y de vanguardia. Este estándar, basado en la tecnología de compresión de video AV1, ofrece una calidad superior con tamaños de archivo significativamente menores en comparación con formatos más tradicionales. Entender cómo transformar tus archivos HDR a AVIF no solo te permitirá mejorar la gestión de tus activos visuales, sino que también asegurará que tus proyectos conserven su impacto visual con una carga más rápida y una mayor compatibilidad en diversas plataformas. Descubre con nosotros los beneficios de esta potente conversión y cómo implementarla eficazmente.

En Latinoamérica, la creciente penetración de internet móvil y la variabilidad en la velocidad de conexión hacen que la eficiencia del formato AVIF sea especialmente valiosa para una experiencia de usuario fluida. En España, su adopción es impulsada por la búsqueda de estándares abiertos y la optimización para dispositivos de última generación.

About HDR to AVIF Conversion

HDR (introduced 1985) and AVIF (introduced 2019) are both image formats, but they differ in important ways. HDR (Radiance) is a high-dynamic-range image format used in lighting and rendering. AVIF is the newest image format based on AV1 video codec, delivering exceptional compression — up to 50% smaller than JPEG at the same quality.

Full Name: HDR uses Radiance HDR Image, while AVIF uses AV1 Image File Format. Compression: HDR uses Lossless, while AVIF uses Lossy & Lossless. Transparency: HDR uses No, while AVIF uses Yes.

When you convert HDR to AVIF, the goal is to optimize files for fast web delivery. Converting HDR to AVIF maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.

Your HDR file is decoded and re-encoded as AVIF. The conversion involves 4 steps: (1) your hdr file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in avif format with optimal settings, (4) the converted file is ready for download.

CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.

This conversion is ideal when you You need a file that works in web browsers. For the opposite direction, CocoConvert also supports AVIF to HDR conversion.

How to Convert HDR to AVIF

  1. 1

    Upload .hdr file

    Select your HDR file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.

  2. 2

    Choose .avif

    Set AVIF as the output format. The converter uses optimal settings based on the HDR→AVIF conversion profile.

  3. 3

    Convert

    The server-side engine decodes your HDR file and re-encodes it as AVIF. Processing time depends on file size and complexity.

  4. 4

    Download result

    Grab your converted .avif file. Multiple output files can be downloaded together.

What Happens When You Convert HDR to AVIF

Your HDR image is decoded into raw pixel data, then re-encoded as AVIF.

1

Your HDR file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels

2

Pixels are re-encoded using AV1 Image File Format's lossless compression

3

Metadata (EXIF, ICC profiles) is transferred where AVIF supports it

4

The AVIF file is saved and ready for download

Full Name: HDR uses Radiance HDR Image, while AVIF uses AV1 Image File Format. Compression: HDR uses Lossless, while AVIF uses Lossy & Lossless. Transparency: HDR uses No, while AVIF uses Yes.

Does HDR to AVIF conversion affect quality?

Converting HDR to AVIF maintains high quality with CocoConvert's optimised encoder settings.

Which format has better compression, HDR or AVIF?

HDR uses lossless compression. AVIF uses both compression. The better choice depends on whether you prioritize file size or quality.

How long does HDR to AVIF conversion take?

Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.

Is HDR or AVIF better for long-term storage?

HDR is better for archival since it's lossless.
