Convert PB to another file type
To convert PB files to another format, you need TensorFlow or other Data software.
Convert a file to PB
To convert other file formats to the "Serialized Protocol Buffer File" file type, you need software like TensorFlow or a similar tool.
About PB files
The .PB file extension is primarily associated with Google Protocol Buffers (Protobuf) and stores structured, serialized data. These files are extensively used to store pre-trained machine learning models in TensorFlow (as SavedModels or frozen inference graphs), transmit real-time public transit data like GTFS Realtime feeds, and log profiling data. The main disadvantage of a .PB file is that it is typically compiled into a highly optimized binary format. Unlike standard text formats, you cannot easily open it in a text editor to verify the contents. Without the original schema definition file (PROTO), reverse-engineering the exact field names and structures is extremely difficult, making data extraction frustrating for developers. Users frequently need to convert .PB data payloads to human-readable formats like JSON or XML for debugging and analysis. If the file is a TensorFlow model, data scientists often convert it to .ONNX or .TFLITE to deploy the model on different edge hardware or mobile devices. Because Protobuf files are schema-dependent binary blobs, standard online converters usually fail to process them. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your PB file, detects the exact format, and lets you read the text inside.
Users also converted PREFERENCES_PB, GOODNOTES, PROTO, PB1, ZIP, ATTACHMENTS, M4S, PBE, TFLITE, KOTLIN_MODULE, DATA-00000-OF-00001, DB and BINARYPB files.
FAQ
If you want to convert PB file to TB, GB, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB or GO, you can use TensorFlow or similar software from the "Serialized Data and ML Models" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to PB, try TensorFlow or another comparable tool in the "Serialized Data and ML Models" category.
The PB 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 PB converter.
