When using the ImageMagick's convert, it is a good practice to use the eps2 format. This make the resulting eps file much smaller because it uses the JPEG compression algorithm (DCT).
So, to convert a.jpg to a.eps do:
convert a.jpg eps2:a.eps
This of course, can be used in a shell script, to convert multiple JPG to EPS.
#!/bin/bash
# example 1
convert myfile.jpg myfile.eps
# example 2
for file in file1.jpg file2.jpg file3.jpg; do
echo convert "$file" $(echo "$file" | sed 's/\.jpg$/\.eps/')
done
要使示例 2 运行，您需要删除 for 循环内的 echo。在删除它之前，请确保它输出的命令正确。
You can use many tools. I recommend using convert command from ImageMagick.
#!/bin/bash
# example 1
convert myfile.jpg myfile.eps
# example 2
for file in file1.jpg file2.jpg file3.jpg; do
echo convert "$file" $(echo "$file" | sed 's/\.jpg$/\.eps/')
done
To make example 2 run you need to remove the echo inside the for-loop. Make sure the commands it outputs are correct before removing it.
According to user1958943, I used the convert tool as well. However, as the eps3 format gives an even better compression with similar quality as eps2, I suggest to use
convert a.jpg eps3:a.eps
By the way, this tool also works for png files (and also others) ...
Does anybody know which compression eps3 is using?

使用 ImageMagick 的转换时，最好使用 eps2 格式。这使得生成的 eps 文件小得多，因为它使用 JPEG 压缩算法 (DCT)。
因此，要将
a.jpg转换为a.eps，请执行以下操作：这当然可以在 shell 脚本中使用，将多个 JPG 转换为 EPS。

您可以使用许多工具。我建议使用 ImageMagick 中的

有人知道 eps3 使用哪种压缩吗？

另一种选择是将 jpegtopnm 和 pnmtops 来自 netpbm 工具包。
然而，这将产生 PS，而不是 EPS。
Another option is to combine jpegtopnm and pnmtops from the netpbm toolkit.
This will however produce PS, not EPS.
ImageMagick 的 convert 可以为您做到这一点。
ImageMagick's convert can do that for you.
我经常这样做，有时在 Windows 上这样做。因此，我编写了一个小型在线转换器，它使用convert：
JPG to EPS Converter。
希望这也可以帮助其他人。
