JPEG 到 BMP 转换器 — 快速免费
JPEG to BMP converts lossy, compressed JPEG pixels into BMP bitmaps (often uncompressed), preserving pixel appearance while typically increasing file size.

How JPEG to BMP Conversion Works
JPEG Image (JPEG) uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. Bitmap Image (BMP) stores uncompressed pixel data in a simple row-by-row grid, resulting in large file sizes but zero quality loss. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. The result is a standard BMP file readable by any compatible application. 1converter handles JPEG-to-BMP conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.

何时使用低/中质量：
- •网页上传和社交媒体分享
- •有大小限制的电子邮件附件
- •快速预览和缩略图
何时使用高/最高质量：
- •专业打印和出版
- •归档和长期存储
- •当质量比大小更重要时
图片提示：中等质量为照片提供最佳平衡。对于带文字的图形，使用高或最高质量以保持清晰度。
为什么要将 JPEG 转换为 BMP？
了解将 JPEG 文件转换为 BMP 格式的优势
BMP supports straightforward pixel-based workflows without JPEG’s lossy re-compression artifacts
Better choice for tools that expect bitmap headers and raw pixel arrays
Often improves compatibility with legacy imaging software and simple raster pipelines
Color depth can be kept as true-color for predictable bitmap rendering
Works well when you need uncompressed or minimally processed raster output
