What is a TGA file?

TGA (Truevision TARGA) is a 1984 raster format that became the de-facto texture container for the game industry through the late 1990s and 2000s. Unreal Engine 4 and 5 still accept TGA as a primary texture format, id Tech (Doom 3, Quake 4), Source (Half-Life 2, CSGO), and CryEngine all build pipelines around it, and Substance Painter exports TGA by default for albedo, normal, and roughness maps. Visual effects shops at ILM, Weta, and DNEG continue to use TGA for matte paintings because the format supports uncompressed 24-bit and 32-bit alpha without colour-management surprises.

Converting TGA to JPG is typically for sharing texture work outside the production pipeline: ArtStation portfolios, client review PDFs, Discord previews, or stock-asset marketplaces like Unity Asset Store and Unreal Marketplace which often want JPG thumbnails alongside the TGA source. Indie game devs working in Blender or Maya export TGA for in-engine use and convert to JPG for promotional screenshots. A typical 4K diffuse map TGA is 48MB uncompressed; the same content as quality-92 JPG drops to 1.8MB without visible loss for portfolio display.

The trap is the alpha channel: 32-bit TGA files carry alpha that JPG cannot store. If you have a texture with embedded transparency (foliage cards, decals, UI elements), tga-to-jpg flattens against the background colour you choose. For foliage cards rendered against magenta or green keying, pick black or white to match your portfolio site's theme. If you need transparency preserved, target PNG instead and keep the TGA as the engine-side master. Substance Painter users should export channel-by-channel rather than packed RGBA to avoid alpha contamination.

Reasons to convert TGA to JPG usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts JPG uploads.
• You need a feature unique to JPG (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that TGA doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the TGA → JPG tool on jpg.now.
2. Drag your TGA file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to JPG. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Strip the alpha before conversion if you don't need it - 32-bit TGA flattened against the wrong colour produces visible halos around foliage cutouts.
• For Unreal Engine portfolio shots, render at the original 4K texture resolution then downscale to 2048 in the JPG - keeps detail while cutting size to portfolio-friendly KBs.
• Substance Painter exports RLE-compressed TGA by default - our converter handles both RLE and uncompressed TGA transparently.
• If exporting from id Tech games, the TGA may be flipped vertically (legacy quirk) - some converters auto-correct, ours follows the TGA header flag.
• For Unity Asset Store thumbnails, the spec is 1200x630 JPG quality 85 - resize TGA to match before submission or the listing flags as low quality.
