在处理图像数据时，效率和文件大小常常是我们关注的焦点。RLE（行程编码）是一种历史悠久且广泛使用的无损压缩方法，尤其擅长处理包含大量重复数据的图像，例如早期的黑白扫描件或简单的图形。然而，当我们需要更极致的压缩比，特别是在传输或存储对带宽和空间敏感的单色图像时，JBIG（联合双层图像专家组）标准便展现出其卓越的优势。JBIG凭借其更先进的算法，能在保持图像质量的同时，将文件大小压缩到RLE难以企及的水平。本页面将深入探讨如何将RLE格式高效转换为JBIG，助您在各种场景下优化图像处理流程。

- 游戏界面黑白素材压缩
- 旧文档扫描件归档
在东亚地区，尤其是处理大量汉字或复杂图形的单色文档时，JBIG压缩比高且对细节保留良好，使其在电子文档、传真传输等领域比RLE更具实用价值，符合对文件体积和传输效率的普遍需求。
