Why Convert JPG to BMP?
BMP is a simple raster format that stores pixels without compression — useful for certain workflows:
- No JPEG artifacts: Avoid repeated lossy re-encodes during editing.
- Straightforward structure: Easy for low-level pixel manipulation.
- Legacy/embedded apps: Some Windows tools prefer BMP.
How to Convert JPG to BMP Online
- Click Upload JPG and select your file.
- Wait for processing to complete.
- Click Download BMP to save your image.
Defaults to 24-bit BMP with no compression.
BMP vs JPG: Key Differences
| Feature | JPG | BMP |
|---|---|---|
| Compression | Lossy (JPEG) | Typically uncompressed (lossless) |
| File size | Small | Large |
| Transparency | No | No (common 24-bit BMP) |
| Best for | Photos, web use | Editing workflows, legacy apps, pixel ops |
Supported Limits & Formats
- Accepted input: JPG/JPEG (
image/jpeg) - Maximum file size: up to 16 MB per file
- Output: BMP (
.bmp, MIMEimage/bmp) - Bit depth: 24-bit (no alpha)
Troubleshooting
- Very large output: BMP is uncompressed by design; consider JPG to PNG for smaller lossless files.
- Transparency needed: BMP (24-bit) has no alpha; use JPG to PNG.
- Upload fails: Ensure file is JPG/JPEG and ≤ 16 MB.
What is JPG?
JPG (JPEG) uses lossy compression to keep files small, ideal for photos and the web, but repeated saving can introduce artifacts.
What is BMP?
BMP is a simple bitmap format that typically stores raw pixels without compression. It’s large in size but easy for programs to read and manipulate.
Use Cases: When to Convert JPG to BMP
- Editing loops: Avoid cumulative JPEG artifacts.
- Legacy software: Older Windows tools that require BMP.
- Development: Direct pixel access in low-level processing.
- Yes, the converter is completely free with no hidden charges or subscriptions.
- BMP is widely supported on Windows and recognized by many other platforms. Some modern workflows prefer PNG/WebP for size efficiency.
- Often several times larger (e.g., 5–20×), since BMP is typically uncompressed.
- You can upload images up to 16 MB per file.
- Files are processed automatically and not retained longer than necessary for conversion.
- This page converts one file at a time. For bulk needs, repeat the process or use a batch tool.
- Common 24-bit BMP doesn’t include an alpha channel. For transparency, convert to PNG instead.
BMP output is intentionally large (uncompressed). For the web, prefer PNG/WebP/AVIF.
