Convert BMP to TGA Online
Massive file sizes (a 1920x1080 image is ~6 MB uncompressed) make it impractical for web or sharing. Converting to TGA gives you a key advantage: simple uncompressed format with native alpha channel support — fast to load and directly usable as gpu texture data. TGA is best for game development texture assets and video post-production frame sequences.
Why Convert BMP to TGA?
Massive file sizes (a 1920x1080 image is ~6 MB uncompressed) make it impractical for web or sharing — converting to TGA overcomes this by providing simple uncompressed format with native alpha channel support — fast to load and directly usable as gpu texture data
TGA is the right choice when you need to: exporting texture maps for 3d game assets with alpha transparency
Gain broader compatibility — TGA works with Game engines (Unity, Unreal), After Effects, Photoshop, GIMP, Blender, FFmpeg
Your BMP files were created for legacy windows application resources and system icon bitmaps, but now you need a format suited to different workflows
BMP vs TGA — Format Comparison
Windows Bitmap (.bmp)
Truevision TGA (TARGA) (.tga)
How to Convert BMP to TGA
Upload your BMP file
Drag your .bmp file onto the upload area or click to browse. We accept BMP files up to 100 MB.
Choose TGA as output format
Select .tga (Truevision TGA (TARGA)) from the format list. TGA uses lossless compression, so your output quality matches the source.
Convert and download
Click Convert and wait for processing. Your TGA file will be ready to download in seconds. The result is optimized for game development texture assets and video post-production frame sequences.
Frequently Asked Questions
Is the BMP to TGA conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. 32-bit RGBA uncompressed or RLE-compressed; no color management or metadata.
How large will my TGA file be compared to the original BMP?
expand_more
BMP files are typically 1 MB – 100 MB, while TGA files are typically 1 MB – 50 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted TGA file?
expand_more
TGA is compatible with: Game engines (Unity, Unreal), After Effects, Photoshop, GIMP, Blender, FFmpeg.
What is the maximum file size I can convert?
expand_more
PureConverter accepts BMP files up to 100 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between BMP and TGA?
expand_more
BMP (Windows Bitmap) is best for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access. TGA (Truevision TGA (TARGA)) is best for game development texture assets and video post-production frame sequences. Key tradeoff: BMP's advantage is zero processing overhead — raw pixel data can be read directly into memory without a decompression step, while TGA's advantage is simple uncompressed format with native alpha channel support — fast to load and directly usable as gpu texture data.
Pro Tips for BMP to TGA Conversion
TGA preserves full quality, so your output file will be as good as the BMP source — no need to worry about compression artifacts
If your BMP file has transparency, make sure TGA supports it — TGA supports transparency
TGA works especially well for: storing video effects render passes with embedded alpha channels
Did you know? TGA was originally designed for Truevision's TARGA graphics cards — one of the first PC cards capable of displaying true-color images, which is why the format natively supports 32-bit RGBA.
