Why Convert HDR to AVIF?
HDR (Radiance) is typically produced by or used with 3D rendering and lighting tools, for lighting and environment maps for 3D rendering. AVIF is expected by modern browsers (Chrome, Firefox, Edge, Safari) instead, for high-efficiency images for fast-loading modern websites — converting bridges that gap.
Our engine reads a file built around lighting and environment maps for 3D rendering and rebuilds it aiming to preserve this: noticeably smaller files than PNG or JPG at comparable quality — rather than producing a generic, lowest-common-denominator result.
HDR (Radiance) works well for lighting and environment maps for 3D rendering, but has a real limitation: not a general-purpose photo format outside rendering workflows. Converting trades that for this: noticeably smaller files than PNG or JPG at comparable quality.

Frequent Questions
Can I convert the file back from AVIF to HDR afterward?
Only what AVIF actually carries can come back — anything specific to HDR (Radiance)'s role in lighting and environment maps for 3D rendering that didn't survive the original conversion won't reappear.
Will I lose anything converting HDR to AVIF?
Converting to AVIF means adapting to a real constraint: unsupported by older browsers and some legacy software. Anything HDR (Radiance) carries — built as it is for lighting and environment maps for 3D rendering — that has no equivalent there won't make the trip, but the core content converts faithfully.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
What software works with the converted AVIF file?
AVIF is used by modern browsers (Chrome, Firefox, Edge, Safari). If you were working with 3D rendering and lighting tools (which produces HDR (Radiance)), this conversion is the direct bridge between the two.
Do I need any special settings before uploading my HDR file?
No special setup is required — upload the file as-is. HDR (Radiance) files meant for lighting and environment maps for 3D rendering convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
