## What it is
SubRenamer is a cross-platform desktop GUI tool that batch renames subtitle files to match their corresponding video file names with one click, so media players auto-load subtitles. It also supports automatic subtitle timeline syncing via integrated FFsubsync and FFmpeg.

## Use cases
- batch rename subtitle files to match video names
- auto-load subtitles in any video player by matching filenames
- sync subtitle timing with video audio automatically
- organize anime episode subtitles for Emby or Jellyfin
- match multilingual subtitle files to videos
- manually match video and subtitle files with custom rules or regex

## When to choose
- you have many episodes with mismatched video and subtitle filenames
- you want one-click automatic matching instead of manual renaming
- you need subtitle timeline auto-sync alongside renaming
- you want a small cross-platform GUI tool for subtitle management

## When to avoid
- you need general-purpose batch file renaming beyond subtitles
- you only need a CLI/scripted renaming workflow
- you need subtitle format conversion or editing of subtitle content
