Your TGA image is decoded into raw pixel data, then re-encoded as HDR. No quality loss — pixel data is preserved exactly.

1

Your TGA file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels

2

Transparency is resolved: transparent pixels are composited onto a white background

3

Pixels are re-encoded using Radiance HDR Image's lossless compression

4

Metadata (EXIF, ICC profiles) is transferred where HDR supports it

5

The HDR file is saved and ready for download
