Convert heic to dds
Converted on your device. Files never leave this tab.
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 HEIC files as you like.
Real DDS output
Encoded by magick, the same library the command-line tools use — not a renamed extension.
About HEIC
HEIC (HEVC-coded HEIF image)
HEVC-compressed images in a HEIF container. iPhones have saved photos this way by default since iOS 11 in 2017, at much smaller sizes than JPG, but Windows and many websites cannot open them without extra codecs. Convert HEIC to JPG or PNG to open iPhone photos on Windows, upload them to sites that reject HEIC, or share them.
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.
