About PQB files
The .PQB file format is a backup archive created by the Pleco Chinese dictionary application for iOS and Android. It stores user-generated data, including custom flashcards, dictionary settings, and study history. Users typically manage .PQB files directly within the Pleco mobile app. Because the underlying structure is based on standard SQL databases, specialized database browsers can sometimes inspect the raw data. The main disadvantage of the .PQB format is its proprietary wrapper. You cannot natively open it in a standard text editor or spreadsheet software like Microsoft Excel. If you want to migrate your Chinese vocabulary lists to another flashcard app (like Anki) or analyze your study habits on a computer, the .PQB format locks your data inside the Pleco ecosystem. To make this data universally usable, you need to convert .PQB to CSV, TXT, or SQL. Converting to CSV extracts the raw vocabulary tables but will strip away Pleco-specific app settings and formatting. This file format is heavily guarded and difficult to open or convert externally. Often, only the original software can properly restore and read the backup data securely. Just drag and drop your file onto convert.guru to identify the format, inspect the underlying database structure, and convert it if standard table extraction is supported.
Convert.Guru analyzes your PQB file, detects the exact format, and lets you read the text inside.
If you want to convert PQB file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Pleco or similar software from the "Flashcard and Settings Backup" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to PQB, try Pleco or another comparable tool in the "Flashcard and Settings Backup" category.
The PQB Converter Story
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 PQB converter.
