We’re excited to share another free tool with the digital forensics community: Calculatrice VarInt. Created by forensic practitioners for practitioners, VarInt Calculator is designed to make decoding and understanding variable-length integers (VarInts) faster and more intuitive.
VarInts appear frequently in mobile app databases, messaging protocols, and structured formats like protobufs. Manually decoding them, especially during reverse engineering, can be time-consuming and prone to error. VarInt Calculator simplifies the process so you can focus on deeper analysis.
What VarInt Calculator Does:
- Convert VarInts from hex to decimal and back
- Instantly view decimal interpretations
- Understand field sizes for strings and blobs in database records and protobufs
- Save time during manual validation and reverse engineering
By removing unnecessary complexity, VarInt Calculator supports faster, more confident mobile artifact analysis.
The Value of Using VarInt Calculator:
Accurately interpreting VarInts is a small but critical step in many forensic investigations, especially when analyzing app artifacts or unknown database structures. VarInt Calculator gives examiners an easy, reliable way to validate values — no custom scripting required.

The tool is free to download and available to the entire forensic community.
