| Editable project | .lunar preserves the canvas, resolution, layers, groups, masks, live adjustments, visibility, opacity, blend modes, locks, and color-space metadata. Current projects remain compatible with earlier project files. |
| Everyday images | PNG, JPEG, WebP, GIF, BMP, and TGA cover transparent graphics, photos, modern web images, indexed-color stills, classic bitmaps, and lossless alpha-capable creative workflows. |
| Advanced conversions | Direct builds handle AVIF, HEIC, DDS, TIFF, and flattened PSD with platform-native or bundled conversion support where available. |
| Icons and documents | ICO creates multi-resolution Windows icons. PDF places the flattened image on a page sized to the artwork at its document resolution. SVG wraps the flattened artwork as an embedded PNG. |
| PSD notice | PSD import and export are flattened. Lunar Paint does not preserve PSD layer structure; use .lunar for editable groups, masks, adjustments, and layers. |
| Color workflow | Supported imports are normalized into an sRGB working canvas. Wide-gamut and CMYK documents are converted for the sRGB workflow, so the original should be retained when exact press-profile or HDR values are required. |
