## How to convert BMP to DDS

1. **Add your BMP files.** Drag and drop BMP files onto the converter, paste them, or click to browse. You can add several at once.
2. **Choose DDS.** DDS is already selected. Open Options if you want to change quality, size or metadata.
3. **Convert.** Click Convert. Your files are converted right in your browser in seconds.
4. **Download your DDS.** Download each DDS file, or everything at once as a ZIP.

## Good to know

- DDS uses lossy compression, so files get much smaller. The default quality is visually lossless for most content; lower it under Options for even smaller files.
- BMP files are typically used for legacy Windows software and raw pixel exchange, while DDS is best for textures for games and real-time 3D.
- This conversion runs on ImageMagick, running locally in your browser — nothing is uploaded and it works even on slow connections.

## BMP vs DDS

|  | BMP | DDS |
| --- | --- | --- |
| Full name | Windows Bitmap | DirectDraw Surface |
| Type | Image | Image |
| Extensions | .bmp | .dds |
| MIME type | image/bmp | image/vnd-ms.dds |
| Best for | legacy Windows software and raw pixel exchange | textures for games and real-time 3D |
| Properties | lossless, legacy format | lossy compression |

**BMP:** BMP is an uncompressed bitmap format from Windows. It's simple and lossless, which also makes files very large.

**DDS:** DDS stores GPU-compressed textures with mipmaps so games can load them directly into video memory.

### Is it safe to convert BMP to DDS here?

Yes. BMP to DDS conversion happens entirely inside your browser using WebAssembly, so your file is never uploaded to any server.

### Is the BMP to DDS converter free?

Yes — free with no watermark. Signed-out visitors can convert 25 files a day, and a free account raises that to 250.

### Will converting BMP to DDS reduce quality?

DDS is a lossy format, but our defaults are tuned to be visually indistinguishable for most files. You can raise the quality under Options.

### Can I convert multiple BMP files at once?

Yes. Add up to 5 files at a time without an account, 10 with a free account and up to 500 on paid plans, then download them individually or as a single ZIP.

### Can I convert DDS back to BMP?

Yes — use our DDS to BMP converter. Note that converting back and forth between formats can't recover detail lost to lossy compression.
