DNG to TGA Converter
Convert DNG to TGA in your browser. A DNG from Adobe DNG Converter may carry only a medium 1024 px preview, and the largest preview in the file is what gets converted. No raw development happens here. You get a run-length encoded 32-bit TGA with alpha. Nothing is uploaded.

Where the TGA goes next
TGA opens in Unreal Engine, Unity, Blender, Photoshop, GIMP and Substance tools.
TGA next to DNG
The TGA holds the camera preview's pixels with lossless compression: usually smaller than a 15 to 40 MB raw file, though far larger than a JPEG of the same photo.
No new artefacts
The preview inside the DNG is a camera JPEG; the TGA stores its decoded pixels losslessly, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
DNG vs TGA
What changes from DNG to TGA
Encoding: the DNG uses lossless (or lossy) JPEG-compressed sensor data, plus optional JPEG previews; TGA uses uncompressed or run-length encoded (RLE), and the download is a run-length encoded 32-bit TGA with alpha.
Bit depth: 8 to 16 bits per channel in the DNG; TGA allows 8, 15, 16, 24 or 32 bits per pixel, and the TGA written here has 32 bits per pixel. The raw data's 12 to 16 bits are not used: the embedded 8-bit preview is converted.
Colour: camera RGB plus the colour matrices that map it to XYZ (demosaiced linear RGB in a Linear DNG) in the DNG; TGA supports RGB, greyscale or a colour map, written here as 8-bit sRGB.
Metadata: the DNG can carry EXIF, XMP and DNG tags for colour matrices, calibration and lens corrections; TGA can carry an image ID field and an optional extension area with author and date, but nothing is copied across.
About DNG
DNG is Adobe's openly documented raw format. Some cameras and phones record it directly, Adobe DNG Converter turns other brands' raw files into it, and a Linear DNG holds already-demosaiced RGB that raw editors treat like any other raw file.
DNG is built on TIFF/EP. The raw image sits in a sub-IFD marked as the main image, with tags for black and white levels, colour matrices and the colour filter pattern; a Linear DNG (PhotometricInterpretation 34892) stores demosaiced RGB instead of a mosaic. Previews are optional, and Adobe DNG Converter can write a medium (1024 px), full-size or no preview.
DNG files usually come from Leica, Pentax and Ricoh cameras, DJI drones, Google Pixel and iPhone ProRAW, and Adobe DNG Converter.
About TGA
TGA is a simple raster format still widely used for game textures and 3D rendering pipelines because it stores alpha channels reliably and loads fast.
A TGA has an 18-byte header (ID length, colour map type, image type 2 for true colour or 10 for RLE, origin, size, bits per pixel and a descriptor byte whose bits give the alpha depth and whether rows run top-down), then the pixels; version 2 files end with a 'TRUEVISION-XFILE' footer.
When converting DNG to TGA makes sense
TGA is the better choice for game textures and 3D software, while DNG suits raw editing and archiving raw files in an open format.
TGA strengths: Reliable alpha channel; Fast and simple to load; Common in game engines. Drawbacks to weigh: Large files; Not viewable in browsers.
Limitations
- Phone DNGs such as Apple ProRAW and Pixel raw are already computationally processed; the preview shows that processed result.
- A Linear DNG without a preview, such as one written by this site, is read from its RGB data instead.
- The run-length encoding used here is lossless, and game engines read compressed and uncompressed TGA alike.
- TGA files do not open in browsers, so keep a PNG for previews.

Frequently asked questions
Does converting DNG to TGA lose quality?
TGA is written losslessly, so the pixels are stored exactly as decoded. Those pixels come from the camera's JPEG preview, so its compression stays, but nothing new is lost. The raw data's 12 to 16 bits are not used: the embedded 8-bit preview is converted.
Which apps open TGA files?
Unreal Engine, Unity, Blender, Photoshop, GIMP and Substance tools. It does not open in web browsers.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
