EmEditor is a lightweight extensible commercial text editor for Microsoft Windows. It was developed by Yutaka Emura of Emurasoft, Inc. EmEditor includes full Unicode support, 32-bit and 64-bit builds, syntax highlighting, find and replace with regular expressions, vertical selection editing, editing of large files (up to 248 GB or 2.1 billion lines), and is extensible via plugins and scripts.[1][2]


Unicode support[edit]

EmEditor supports Unicode and provides tools for work with various character encodings. These features include automatic encoding detection, byte order mark support, file reload with a different encoding, and detection of encoding errors. EmEditor can use any encoding supported by Windows and easily converts from one encoding to another. The program opens Unicode file names and searches for Unicode characters.

Large files[edit]

EmEditor is capable of supporting very large file sizes without losing functionality.[3] Instead of opening large files in memory, EmEditor spills out large files into disk space. This allows the program to handle files up to 248 GB. For files larger than this, the program uses its Large File Controller which opens sections of a large file at a time for editing.


EmEditor is extensible via plug-ins written in C/C++. The editor's API is available, so that users can write their own plug-ins.

The following plug-ins are installed with EmEditor by default:

  • HTMLBar
  • Open Documents
  • Outline
  • Projects
  • Search
  • Snippets
  • WebPreview
  • WordComplete
  • Word Count

An optional 32-bit plug-in for CSE HTML Validator support is also available.[4]

Scripting macros[edit]

The program is scriptable using the Windows Script Host. The program's scripts are written in either JScript or VBScript. EmEditor can generally be scripted in any scripting language that supports Active Scripting. The program includes powerful macros.[5]

Awards and nominations[edit]

  • EmEditor Professional has been nominated for the Epsilon Award 2010. Later it won the second place of the award.[6]
  • EmEditor 10.0 was awarded a 5/5 cows Editor's Rating on tucows.[7]
