Extract text from Android media markers (NOMEDIA)
To convert NOMEDIA Media markers to another format, you need Android OS or other System software.
To convert other file formats to the "Android Hidden Marker" file type, you need software like Android OS or a similar tool.
The .nomedia file is primarily a directory marker used by the Android operating system. When placed inside a folder, it instructs the Android OS media scanner to ignore that directory, preventing any contained images, videos, or audio from showing up in your gallery or media player apps. This mechanism is standard practice for hiding app caches, voice notes, or raw system assets.
While traditional .nomedia files are completely empty (0 bytes), certain apps like Snapchat or WhatsApp exploit this extension to intentionally disguise downloaded media. In these edge cases, the file actually contains raw MP4 video data, JPG image data, or PNG overlays disguised under a false file extension.
The main disadvantage of the .nomedia format is that it intentionally breaks media playback. You cannot open these files natively on a desktop computer, and they remain invisible on mobile devices without a specialized file manager. If you are extracting cached files from a smartphone backup, dealing with disguised .nomedia files is highly frustrating because the operating system does not know which application to use to decode the hidden data.
If your file is larger than 0 bytes, it likely contains hidden media. For hidden videos, convert to MP4. For hidden images, convert to JPG or PNG for instant viewing. If the file is 0 bytes, no conversion is necessary; you can simply delete it from your Android device to unhide the folder's contents.

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 NOMEDIA converter.
