OpenEXR Files and Web Browsers

EXR files store high dynamic range images used in film production, visual effects, and professional photography. The problem: no web browser can display them natively. When you try to view an EXR file in a browser, nothing happens.

Converting EXR to HTML solves this by creating a web page with an embedded, viewable version of your image. In our testing, the conversion preserves visual quality while making your HDR content accessible to anyone with a browser. For other EXR file conversions, we support multiple output formats.

How to Convert EXR to HTML

  1. Upload your EXR file - Drag and drop or click to select your OpenEXR image
  2. Select HTML as output - Choose HTML from the format options
  3. Download your HTML file - Open it in any browser or embed it in your website

The entire process runs in your browser. Your professional images stay private on your device.

Why EXR Needs Conversion

OpenEXR was developed by Industrial Light & Magic for film production. It stores 16-bit or 32-bit floating-point color data per channel-far beyond what standard web formats support:

  • Dynamic range - EXR captures light values from deep shadows to bright highlights that monitors cannot display directly
  • Color depth - 16-bit half-float or 32-bit float versus JPG's 8-bit integer values
  • Multi-channel - EXR can store depth, normals, motion vectors alongside color data
  • File size - Raw EXR files are typically too large for web delivery

HTML conversion tone-maps the HDR data into viewable range while creating a self-contained web page.

Common Use Cases

Sharing VFX Work

You rendered a scene in Nuke or After Effects and need to show a client who does not have professional software. Convert to HTML and send a single file they can open in Chrome or Safari.

Portfolio Websites

Display your HDR photography or CGI renders on a web portfolio. The HTML output embeds cleanly into existing pages.

Quick Previews

Need to review EXR renders without launching heavy software? Convert to HTML for instant browser-based viewing. For permanent archival, consider EXR to PNG which preserves more data.

Alternative Output Formats

HTML works well for sharing and quick viewing, but other formats may suit specific needs:

  • EXR to JPG - Smaller files for general sharing, some quality loss
  • EXR to PNG - Lossless compression, better for graphics with sharp edges
  • EXR to TIFF - Professional print workflows requiring high bit depth

Choose HTML when you need instant viewing in any browser without requiring additional software.

Works on Any Device

Our EXR to HTML converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPad and Android tablets

No plugins, no installations, no account required.

Pro Tip

When sharing EXR renders with clients, convert to HTML for quick browser viewing but also provide PNG versions for reference. The HTML gives instant access while PNG preserves more tonal accuracy for approval decisions.

Common Mistake

Expecting HTML output to show the full dynamic range of EXR files. Monitors have limited brightness range-the conversion necessarily compresses highlights and shadows to fit displayable values.

Best For

Sharing VFX renders, CGI work, or HDR photography with people who don't have OpenEXR-compatible software. Perfect for client reviews, portfolio previews, and quick file checks.

Not Recommended

Don't use HTML conversion as your archive format. If you need to preserve EXR data for future editing, keep the original EXR files. HTML is for viewing and sharing, not storage.

Frequently Asked Questions

EXR (OpenEXR) is a high dynamic range image format created by Industrial Light & Magic. It stores floating-point color values with much greater range and precision than standard image formats, making it the industry standard for film visual effects and CGI.

Web browsers only support standard formats like JPG, PNG, GIF, and WebP. EXR's 16-bit or 32-bit floating-point data and multi-channel structure require specialized software to decode and display properly.

The conversion applies tone mapping to fit EXR's high dynamic range into displayable values. You'll see a representative version of your image, though the extreme highlight and shadow detail that exceeds monitor capabilities will be compressed.

Yes. The converted HTML file contains everything needed to display the image. You can use it standalone or extract the relevant code to embed in your existing web pages.

The primary color channels (RGB) are converted and displayed. Additional EXR channels like depth, alpha, or motion vectors are not rendered in the HTML output-those require specialized software.

No. The conversion happens entirely in your browser using client-side processing. Your files never leave your device, which matters for proprietary VFX work or unreleased film assets.

Browser-based conversion depends on your device's available memory. Most systems handle EXR files up to 100-200MB without issues. Very large multi-layer EXR files may require desktop software.

Yes. Upload multiple EXR files and convert them to HTML in a single batch. This is useful when preparing a series of renders for client review.

EXR is output by professional tools including Nuke, After Effects, Blender, Maya, Houdini, DaVinci Resolve, and most 3D rendering engines. High-end cameras and HDR photography software also export EXR.
