Extract text from Index files (IDX)
To convert IDX Indexes to another format, you need VLC media player or other Data software.
To convert other file formats to the "Index File" file type, you need software like VLC media player or a similar tool.
An .idx file is primarily an index file used by various software to speed up database searches, cache thumbnails, or map data to a larger companion file. The most common user-facing applications are VobSub subtitle indexes (paired with sub files), Dahua Technology DVR security camera metadata, and thumbnail caches for older software like Google Picasa.
Because .idx is a generic extension, it is highly fragmented and causes significant confusion. A VobSub .idx file is completely useless on its own; it requires the companion sub file to display anything. Furthermore, VobSub subtitles are extracted DVD image bitmaps, not text. You cannot easily edit them, fix typos, or change their font size in standard media players. Similarly, a Dahua security camera .idx file is not a playable video - it only tells the DVR player where the motion events are located inside a massive, proprietary raw video file. System index files (like Git packs, Microsoft FoxPro databases, or Antivirus signatures) are entirely binary and cannot be read by humans.
You cannot just "play" or "read" an .idx file. For video use, you must convert VobSub .idx and sub pairs to a universally supported text format like SRT or VTT. Because the source is image-based, this requires Optical Character Recognition (OCR) software. For DVR files, you must use proprietary tools to export the bundle into standard MP4 or AVI files for viewing. If you have an unknown .idx file, drop your file here to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your IDX file, detects the exact format, and lets you read the text inside.
Users also converted SUB, DAV, 264, INDEX, IDDX, IDX3-UBYTE, LGH, DAT, IDX_, PACK, IDX00, TXT and IDX2 files.
If you want to convert IDX file to SRT, MP4, JPG, CSV, PDF, JSON, XML, YAML, YML, TOML, INI or CFG, you can use VLC media player or similar software from the "Data Indexing and Subtitle Mapping" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to IDX, try VLC media player or another comparable tool in the "Data Indexing and Subtitle Mapping" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IDX converter.
