Nothing is uploaded
The converter runs inside this page. Cut your network after it loads and it still works.
No account, no daily limit
No sign-up, no daily limit, no watermark, no queue behind other people's files. Batch as many HDR files as you like.
Real DDS output
Encoded by magick, the same library the command-line tools use — not a renamed extension.
About HDR
Radiance HDR
The HDR format from the Radiance renderer, storing each pixel as red, green and blue values with a shared exponent byte, so it holds a far wider brightness range than 8-bit images. Most HDRI environment maps ship in this format. Use it to light 3D scenes, or convert from it to get an ordinary 8-bit preview.
About DDS
DirectDraw Surface
Microsoft's DirectX texture container. It usually stores GPU-compressed data (the DXT or BCn formats) with mipmaps, so a graphics card can load it without decoding. Convert to DDS for game textures and mods; convert from it to view or edit a texture.
