How JPEG to HDR Conversion Works
The JPEG Image format uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. Converting to HDR produces a document file that stores data in the HDR format. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. This makes HDR the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.

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 HDR？
了解将 JPEG 文件转换为 HDR 格式的优势
Expands dynamic range for brighter highlights and deeper shadows compared with standard JPEG tone mapping
Produces HDR metadata/encoding for compatible HDR displays to render stronger contrast
Keeps fine detail where JPEG artifacts are minimal (e.g., low-compression photos)
Improves grading workflow by providing an HDR baseline for further tone/contrast adjustments
Maintains compatibility with HDR-capable viewers and editors that recognize HDR transfer characteristics
