Convert Radiance HDR (.hdr) to DDS for free. Choose files, review the available settings and download your results. No account needed.
An RGBE raster format that represents a wider brightness range than ordinary display images.
Exports contain a flattened raster image. Editing uses 8-bit browser display precision; original layers, metadata, HDR range, and scientific sample values are not retained.
HDR file format guideA texture container used in graphics and game development. DDS can carry compressed image surfaces and mipmaps.
Export writes a single flattened texture. Cubemaps, mipmap chains, and engine-specific texture properties are not preserved.
DDS file format guideChoose dimensions and image quality before converting. Still-image exports keep one frame. Unedited GIF, WebP, AVIF, JPEG XL and MNG conversions can retain animation. Animated edits use a GIF intermediate with a limited color palette. Canvas editing uses browser display precision and does not preserve original EXIF, HDR, or scientific image data.
Processing uses your device when possible and our servers when required. Browser files are limited to 256 MB each; server conversions to 64 MB; browser spreadsheets to 32 MB. Previews show supported content and do not guarantee identical rendering in every application.
