EXR to AVIF — Format Comparison & Online Converter
Fast, instant OPENEXR to AVIF conversion. No signup required. Just drop your .exr file and get .avif in seconds.
Batch Settings
Layers will be flattened
EXR supports multiple layers, but AVIF does not. All layers will be merged into a single flat image. Keep your original EXR file if you need to edit individual layers later.
Some metadata may not survive
Your EXR file may contain extensive custom attributes metadata. AVIF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 32-bit → 12-bit
EXR 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.
映像制作の現場で広く使われるEXRファイルは、その豊かな色深度と広いダイナミックレンジで、クリエイターの皆様に計り知れない表現の自由をもたらしてきました。しかし、ウェブ上での共有やモバイルデバイスでの閲覧を考慮すると、ファイルサイズの大きさや対応状況が課題となることも少なくありません。そこで注目されるのが、次世代の画像フォーマットであるAVIFです。AVIFは、EXRが持つ高品質な情報を保ちつつ、驚異的な圧縮率を実現します。これにより、読み込み速度の向上はもちろんのこと、ストレージの効率化にも貢献。繊細なグラデーションから鮮やかな色彩まで、EXRの魅力を損なうことなく、より多くの人々に届けるための最適な選択肢となるでしょう。当社の変換ツールは、このEXRからAVIFへの移行をスムーズにサポートし、皆様の創造的なワークフローを加速させます。

About OPENEXR to AVIF Conversion
EXR (introduced 2003) and AVIF (introduced 2019) are both image formats, but they differ in important ways. EXR (OpenEXR) is a high-dynamic-range format used in VFX, film, and 3D rendering pipelines. 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: EXR uses OpenEXR Image, while AVIF uses AV1 Image File Format. Compression: EXR uses Lossy & Lossless, while AVIF uses Lossy & Lossless. Transparency: EXR uses Yes, while AVIF uses Yes.
When you convert EXR to AVIF, the goal is to optimize files for fast web delivery. Converting EXR 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 EXR file is decoded and re-encoded as AVIF. The conversion involves 4 steps: (1) your exr 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 EXR conversion.
How to Convert OPENEXR to AVIF
- 1
Upload .exr file
Select your EXR file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .avif
Set AVIF as the output format. The converter uses optimal settings based on the EXR→AVIF conversion profile.
- 3
Convert
The server-side engine decodes your EXR file and re-encodes it as AVIF. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .avif file. Multiple output files can be downloaded together.
What Happens When You Convert OPENEXR to AVIF
Your EXR image is decoded into raw pixel data, then re-encoded as AVIF.
Your EXR file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Pixels are re-encoded using AV1 Image File Format's lossless compression
Metadata (EXIF, ICC profiles) is transferred where AVIF supports it
The AVIF file is saved and ready for download
