Nothing is uploaded
The converter runs inside this page. Cut your network after it loads and it still works.

No sign-up, no daily limit, no watermark, no queue behind other people's files. Batch as many DDS files as you like.
Real FITS output
Encoded by magick, the same library the command-line tools use — not a renamed extension.
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.
About FITS
Flexible Image Transport System
The standard data format in astronomy since 1981, storing images and tables behind plain-text headers that record telescope and observation details. Convert from FITS to get a viewable PNG or JPG of telescope data; convert to it for astronomy software.
