Why ToFormat?
Lossless RLE Compression
TGA supports Run‑Length Encoding (RLE) compression that reduces file size without losing quality. Ideal for archiving or distributing graphics where every pixel matters.
Alpha Channel Support
TGA natively supports transparency (alpha channel). If your BMP has an alpha layer (rare), we preserve it. You can also add transparency from a color key.
Batch Processing
Upload up to 20 BMP files at once. We'll convert them to TGA with your chosen settings and package them in a ZIP for easy download.
About the Formats
🖼️ What is BMP?
BMP (Bitmap) is a raster graphics format developed by Microsoft. It stores pixel data uncompressed (usually), resulting in large files but exact fidelity. It's the simplest format, supported everywhere, but impractical for web use due to size.
All BMP conversion tools →🎮 What is TGA?
TGA (Truevision TGA) is a raster format originally designed for Truevision video boards. It supports 8, 16, 24, and 32 bits per pixel (including alpha), and uses lossless RLE compression. TGA is widely used in video editing, 3D graphics, texture mapping, and legacy game development.

Upload your BMP
Click or drag and drop your BMP files. You can select up to 20 at once.
Choose TGA options
Select compression (RLE or uncompressed). Enable transparency if needed (alpha from source or set a color key). Choose color depth (24‑bit RGB or 32‑bit RGBA).
Download TGA
Your TGA files are ready. Download individually or as ZIP. Files auto‑delete in 10 minutes.
When to Convert BMP to TGA
🎮 Game Development
TGA is a common texture format in game engines (Unreal, Unity). Convert BMP to TGA with RLE compression for faster loading and smaller package sizes.
💡 Need modern format? Try BMP to WebP →🎬 Video Editing
TGA sequences are used in video production for high‑quality frames. Convert BMP sequences to TGA for import into After Effects, Premiere, or DaVinci Resolve.
💡 For photos: BMP to JPG →🖥️ Legacy Software
Older graphics applications often require TGA. Convert your modern BMPs to TGA to use in vintage software or hardware.
💡 Also try BMP to PNG →🔄 3D Rendering
TGA is supported by many 3D renderers for texture maps, including alpha channels. Convert BMP to 32‑bit TGA for transparent textures.

💡 Pro Tips
- Use RLE compression for lossless size reduction – typical savings 20-40% without any quality loss. It’s widely supported in TGA readers.
- For transparency, use 32‑bit TGA with alpha channel. If your BMP has no alpha, you can set a specific color (e.g., magenta) to become transparent using the color‑key option.
- TGA supports different color depths: 24‑bit RGB (no alpha) or 32‑bit RGBA (with alpha). Choose based on your needs.
- Convert in batch mode – upload multiple BMPs and download all TGAs as a ZIP archive. Great for texture packs.
- We strip metadata by default for privacy. TGA rarely contains EXIF, but any metadata from BMP is removed.
- If you are targeting older software, uncompressed TGA may be more compatible. Test with your target application.
- TGA files can also be used as image sequences in video post‑production. Upload BMPs in order to maintain the sequence.
How BMP to TGA Conversion Works
BMP stores pixel data uncompressed, making it a reliable source for lossless conversion. TGA is a flexible format that can store pixels in various depths and optionally apply RLE compression. When you convert, our server decodes the BMP to raw pixel data, then encodes it as a TGA with your chosen settings: bit depth, compression, and transparency options. RLE compression works by replacing repeated pixel sequences with shorter codes, reducing file size without altering image data.
All processing is done in memory, and your files are permanently deleted after 10 minutes.
BMP vs TGA: Key Differences
Compression: BMP is usually uncompressed → large files. TGA supports lossless RLE compression → smaller files.
Alpha channel: BMP rarely supports alpha; TGA natively supports 32‑bit with alpha (8‑bit per channel + 8‑bit alpha).
Color depth: BMP typically up to 24‑bit; TGA supports 8, 16, 24, and 32‑bit.
Use cases: BMP for simple storage; TGA for game development, video editing, and 3D graphics.
When to Convert BMP to TGA
Convert BMP to TGA when you need a format compatible with game engines, video software, or legacy systems. TGA’s RLE compression saves space while maintaining perfect quality – ideal for texture atlases, sprite sheets, and image sequences. Always keep the original BMP for archival purposes, but for production pipelines TGA is often required.
