TextureView

A macOS app for viewing and converting textures and images.

TextureView opens DDS, KTX2, OpenEXR, HDR, QOI, and the common image formats, and shows what an ordinary viewer doesn't: array slices, cube faces, mip levels, and raw HDR values. It can save textures losslessly to DDS or KTX2, or re‑encode the current image to another format.

• Formats. DDS (legacy and DX10, BC1–BC7, cube maps, arrays, mip chains), KTX2, OpenEXR (single and multi-part), Radiance HDR, QOI, PNG, JPEG, BMP, TGA, PSD, GIF, and Netpbm.
• Viewing. Browse array slices and cube faces, play array slices and animated GIFs as a flipbook, show a single mip level or the whole chain, and switch between point, linear, and trilinear sampling. View panoramas in a 360° equirectangular mode and look around cube maps from inside the cube.
• Inspect. Hold Ctrl to read the texel under the pointer: its color, channel values, and the same value across float, sRGB, HSV, and packed encodings.
• HDR. Adjust exposure and the tone‑mapping operator; output HDR on displays that have the headroom.
• Create. File ▸ New builds an array texture from a set of input files, resampling or transcoding each to a chosen size and pixel format.
• Export. Write the current slice and mip to QOI, PNG, BMP, TGA, JPEG, HDR, GIF, DDS, KTX2, or EXR, optionally generating a mip chain and BC compression; multi-slice textures can be written as an animated GIF or multi-part EXR. Or save the whole texture losslessly to a DDS or KTX2 container with Save As.
• Finder. Adds Quick Look previews and thumbnails for the formats macOS doesn't preview itself.
