# Image Formats for ScreenshotKit Captures

> Compare PNG, TGA, JPEG, and EXR export formats and learn which to use for transparency, HDR, compression, and compositing workflows.

Set the format under **Settings > File Format**. It applies to screenshots, sequences, and matte passes (with one exception noted below).

| Format   | Alpha | HDR | Lossy    | Use when                                                                                      |
| -------- | ----- | --- | -------- | --------------------------------------------------------------------------------------------- |
| **PNG**  | Yes   | No  | No       | General use, transparent screenshots, sharing. Default.                                       |
| **TGA**  | Yes   | No  | No       | Pipelines that prefer TGA (some game engines, older comp tools).                              |
| **JPEG** | No    | No  | Yes      | Smallest files, social media, when alpha is not needed. Quality slider 1 to 100.              |
| **EXR**  | Yes   | Yes | Lossless | HDR captures, linear-light compositing. Compression: None / ZIP / RLE. Optional 32-bit float. |

<Note>
  Multi-layer EXR Cryptomatte mode forces `.exr` for ID passes regardless of the global format, because Cryptomatte data only exists as EXR.
</Note>

<Tip>
  For HDR sequences, pick **EXR** with **32-bit Float** enabled, and use **ZIP** or **RLE** compression to keep file sizes sensible.
