TGA to DNG Converter
Convert TGA to DNG in your browser. TGA files usually come from game engines, 3D renderers and texture painting tools; DNG is the better fit for raw editing and archiving raw files in an open format. You get a Linear DNG: demosaiced 8-bit RGB with the colour matrices raw editors need. Nothing is uploaded.

How to use TGA to DNG
- 1
Add your TGA files: drop them here, choose them, or paste from the clipboard.
- 2
Pick the colour that replaces transparent areas, since DNG has none.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .dng files one at a time or together as a ZIP.
Why use Aback Images for tga to dng
Where the DNG goes next
DNG opens in Lightroom, Photoshop Camera Raw, Capture One, darktable, RawTherapee, Affinity Photo and macOS Photos.
DNG next to TGA
Neither format compresses much, so the DNG lands close to the TGA in size.
Written without a lossy pass
The DNG is written uncompressed, so the pixels decoded from the TGA arrive unchanged.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
TGA vs DNG
What changes from TGA to DNG
Encoding: the TGA uses uncompressed or run-length encoded (RLE); DNG uses lossless (or lossy) JPEG-compressed sensor data, plus optional JPEG previews, and the download is a Linear DNG: demosaiced 8-bit RGB with the colour matrices raw editors need.
Bit depth: 8, 15, 16, 24 or 32 bits per pixel in the TGA; DNG allows 8 to 16 bits per channel, and the DNG written here has 8 bits per channel, linearised.
Colour: RGB, greyscale or a colour map in the TGA; DNG supports camera RGB plus the colour matrices that map it to XYZ (demosaiced linear RGB in a Linear DNG), written here as 8-bit sRGB.
Transparency: the TGA stores it as the fourth byte of each 32-bit pixel (or one bit in 16-bit files); the DNG has none, so transparent areas are filled with the colour you choose.
Metadata: the TGA can carry an image ID field and an optional extension area with author and date; DNG can carry EXIF, XMP and DNG tags for colour matrices, calibration and lens corrections, but nothing is copied across.
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.
TGA files usually come from game engines, 3D renderers and texture painting tools.
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.
When converting TGA to DNG makes sense
DNG is the better choice for raw editing and archiving raw files in an open format, while TGA suits game textures and 3D software.
DNG strengths: Open specification read by every raw editor; Lossless compression and optional previews; Recorded directly by Leica, Pentax, DJI drones and phones. Drawbacks to weigh: Large files; No browser or ordinary photo viewer support on every platform.
Limitations
- Some writers store rows bottom-up and some top-down; the descriptor byte says which, and the decoder follows it, so orientation is preserved.
- Game textures often hide data in the alpha byte (gloss or height); a target without transparency discards it.
- The DNG holds the decoded 8-bit pixels, so it adds no dynamic range or detail beyond the TGA.
- Raw editors apply their own default profile and tone curve to a DNG, so it can look slightly different from the source until you adjust it.
- A Linear DNG has no sensor mosaic, so demosaicing settings in your raw editor have no effect on it.

Frequently asked questions
Does converting TGA to DNG lose quality?
DNG is written uncompressed, so the pixels are stored exactly as decoded.
What happens to transparency when converting TGA to DNG?
TGA stores transparency as the fourth byte of each 32-bit pixel (or one bit in 16-bit files). DNG has no alpha channel, so transparent pixels are composited onto a solid colour, white unless you pick another. To keep transparency, convert to PNG, WebP or AVIF instead.
Can Lightroom edit this DNG like a camera raw file?
It opens with the full raw controls in Lightroom, Photoshop Camera Raw, Capture One and darktable, because it is a valid Linear DNG. It holds the decoded 8-bit pixels, though, so it has no more dynamic range or detail than the image it came from.
Which apps open DNG files?
Lightroom, Photoshop Camera Raw, Capture One, darktable, RawTherapee, Affinity Photo and macOS Photos. 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.
