Fast, secure BMP to TGA conversion. No registration required.
Here is the short version — BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect. Hence the need for TGA. A BMP → TGA operation is one of the simplest image jobs there is: same pixel grid, different wrapper. What genuinely changes is how lossy the codec is, whether alpha survives, and how large the final file ends up. KaijuConverter picks safe defaults for each of those and lets you override them under Advanced. One more beat. BMP is the uncompressed Windows bitmap format — bulky but pixel-perfect. Receiving format: TGA (Targa) is a legacy raster format still common in game asset pipelines.
BMP Image
Source formatBMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.
TGA Image
Target formatTGA (Targa) is a raster graphics format used in game development and video editing.
Why convert BMP to TGA
The real reason to move from BMP to TGA is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking TGA solves those edge cases at the cost of a short conversion step.
HOW TO CONVERT
BMP → TGA
Provide the BMP
Click or drag to upload. We accept a single BMP file per job, with an optional queue of additional images for batch mode.
Encode to TGA
The conversion decodes the BMP, resolves the colour space to sRGB and writes the TGA container around the pixel data.
Save the TGA
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all TGA outputs is produced instead.
Common Use Cases
Share across platforms
Send TGA files to anyone without worrying about whether they have the right software for BMP.
Embed in documents
Drop TGA output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TGA often produces smaller files than BMP for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
BMP vs TGA — Strengths and limitations
What each format does best, and where it falls short.
BMP Strengths
- Dead-simple format — trivially easy to read and write.
- Lossless and uncompressed — perfect bit-exact pixel storage.
- Universally supported in Windows applications since 1985.
- Supports 1, 4, 8, 16, 24, and 32-bit color depths.
Limitations
- Enormous file sizes — no meaningful compression in typical use.
- Not a web format — browsers support it but nobody serves BMPs over HTTP.
- No metadata support (no EXIF, no ICC profile in practice).
TGA Strengths
- Extremely simple — trivially easy to read and write.
- Lossless with optional RLE compression.
- Supports 8, 16, 24, and 32-bit color with alpha channel.
- Universal in legacy game development and 3D rendering pipelines.
Limitations
- No metadata, no color profile, no gamma correction.
- Aging — PNG and EXR cover its use cases with better compression.
- Bottom-up pixel order trips up newcomer parsers.

Quality & Compatibility
BMP-to-TGA conversion does not change the visible content. Quality is capped by the BMP decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original BMP alongside the TGA copy.
Tips for Best Results
- Large BMP files may look identical to small TGA files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export TGA at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related BMP images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both BMP and TGA are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If TGA is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded BMP exactly, but cannot recover detail that BMP had already compressed away.
Often yes, especially when TGA is lossless. BMP tuned for efficient web delivery will usually produce smaller files than TGA's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
