JPG to TGA Converter
Convert JPG to TGA in your browser. JPG files usually come from cameras, phones, scanners and almost every app that saves photos; TGA is the better fit for game textures and 3D software. You get a run-length encoded 32-bit TGA with alpha. Nothing is uploaded.

Why use Aback Images for jpg to tga
Where the TGA goes next
TGA opens in Unreal Engine, Unity, Blender, Photoshop, GIMP and Substance tools.
TGA next to JPG
The TGA keeps the decoded pixels without lossy compression, so expect it to be larger than the JPG.
No new artefacts
JPG is already lossy, since it stores lossy DCT coding in 8×8 pixel blocks, with colour usually stored at half resolution; the TGA keeps the 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.
JPG vs TGA
What changes from JPG to TGA
Encoding: the JPG uses lossy DCT coding in 8×8 pixel blocks, with colour usually stored at half resolution; TGA uses uncompressed or run-length encoded (RLE), and the download is a run-length encoded 32-bit TGA with alpha.
Bit depth: 8 bits per channel in the JPG; TGA allows 8, 15, 16, 24 or 32 bits per pixel, and the TGA written here has 32 bits per pixel.
Colour: YCbCr shown as RGB, greyscale, or CMYK from print software in the JPG; TGA supports RGB, greyscale or a colour map, written here as 8-bit sRGB.
Metadata: the JPG can carry EXIF (camera, date, GPS), XMP, IPTC and an ICC profile in APP segments; TGA can carry an image ID field and an optional extension area with author and date, but nothing is copied across.
About JPG
JPEG is the universal photo format. It compresses by discarding fine detail the eye is least sensitive to, which makes photos small but blurs sharp edges and text if pushed too far.
A JPEG starts with the bytes FF D8 and is a run of marker segments: APP1 carries EXIF and often a thumbnail, APP2 an ICC profile, DQT the quantization tables that decide the quality, and SOS the compressed scan, which ends at FF D9.
JPG files usually come from cameras, phones, scanners and almost every app that saves photos.
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 JPG to TGA makes sense
TGA is the better choice for game textures and 3D software, while JPG suits photographs that need to open anywhere.
TGA strengths: Reliable alpha channel; Fast and simple to load; Common in game engines. Drawbacks to weigh: Large files; Not viewable in browsers.
Limitations
- JPEG artefacts already in the file, such as blocking near edges and smeared colour, are kept as pixels: a lossless target preserves them faithfully rather than removing them.
- 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 JPG to TGA lose quality?
TGA is written losslessly, so the pixels are stored exactly as decoded. Artefacts already in the JPG stay, but nothing new is lost.
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.
