# File Formats and Layering

# File formats and layering
Use whatever software you are comfortable with. Nobody needs Photoshop.
## Finished PNG — required
Full quality/lossless, transparent where appropriate, RGB/sRGB, and keep a high-resolution master.
## Original layered source — required when applicable
Submit the native layered file you actually worked in: `.kra`, `.clip`, `.xcf`, `.procreate`, `.afdesign`, `.afphoto`, `.psd`, or whatever your software uses.
## Open/interchange copy — optional
OpenRaster `.ora` is useful when supported. A layered TIFF or PSD export is welcome as an extra but is not required.
## Vector art
For logos, icons, buttons and UI, include `.svg` when possible.
Keep useful parts on sensible layers and work larger than the tiny legacy asset when practical. Engineering can handle SWF/game integration.
