TGA to 7Z Converter
Processing entirely on your device — large files may take a moment.
TGA (Targa) is the texture format of classic 3D and game pipelines — simple raster data, often with an alpha channel. 7Z is ideal for big archives you store or share with power users; convert to ZIP when the recipient just needs to double-click.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How TGA compares to 7Z

About the TGA format
TGA (Truevision Targa, 1984) was the file format of early video digitizer boards and became the texture standard of classic game and 3D pipelines. It is raster data with almost no ceremony: a small header, optional RLE compression, 8/24/32-bit pixels, alpha optional. Half the 3D engines of the 90s read nothing else.
Modern design and web tools have quietly dropped it, but art asset dumps, texture mods and game extracts still arrive as TGA. Converting to PNG (lossless, with alpha intact) or JPG brings these assets into anything current.
+Strengths
- ✓Trivially simple, lossless raster storage
- ✓Alpha channel support
- ✓The texture format of classic game pipelines
!Limitations
- −Dropped by modern design and web tools
- −No metadata ecosystem
- −Files can be large when uncompressed
About the 7Z format
7Z is the native format of Igor Pavlov's 7-Zip (1999), built around LZMA/LZMA2 compression — for years the ratio king against ZIP and RAR — with AES-256 encryption, solid archiving (similar files compress as one stream) and open, unpatented specifications. A 7Z of the same photos or code is routinely 20–40% smaller than its ZIP.
The trade-off is platform defaults: Windows Explorer and macOS Archive Utility do not open 7Z without third-party tools (7-Zip, PeaZip, Keka). It is the format for maximizing compression on your own terms, and for encrypted archives done properly (header encryption included).
+Strengths
- ✓Top-tier compression ratio (LZMA2)
- ✓Real AES-256 encryption, optional header encryption
- ✓Open format, free tooling everywhere
!Limitations
- −No native OS support — recipients need tools
- −Solid mode makes single-file extraction costly
Why convert TGA to 7Z?
There is a concrete reason this conversion exists: Dropped by modern design and web tools 7Z sidesteps that — Top-tier compression ratio (LZMA2) If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this TGA to 7Z converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting TGA to 7Z?
No — 7Z is a lossless format, so every pixel of the converted image matches your original TGA file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to 7Z?
Transparency is kept whenever 7Z actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your TGA files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
