Varint Calculator
Utilities
$29.99
Instantly decode and understand SQLite varints with live feedback, overflow detection, and an interactive tutorial for learning manual decoding.
Varint Calculator is a powerful utility for anyone working with SQLite databases, digital forensics, or low-level data analysis. More than just a simple decoder, it provides on-the-fly interpretation of varints, serial types, and payload calculations so you can decode, understand, and validate data with confidence.
Key Features:
Live Varint Decoding – As you type a hex string, the app automatically validates input, checks for complete byte pairs, and instantly converts to the correct integer value.
Smart Serial Type Detection – Automatically identifies SQLite serial types (e.g., integer, floating point, text, blob) and shows the corresponding length or interpretation.
MSB Guidance – Highlights when the Most Significant Bit indicates additional bytes are required, helping you learn to decode varints manually.
Overflow Page Calculations – Uses a default page size of 4096 bytes to determine when overflow occurs, and calculates exactly how many bytes remain in the local payload. Users can adjust page size with a long press for different database configurations.
Interactive Tutorial Mode – Step-by-step walkthrough of varint decoding, giving you the skills to manually interpret values as well as rely on the calculator.
History Tracking – Saves recent calculations for quick reuse. Clear individual entries or wipe the full history when needed.
Designed for Accuracy and Learning – Built for forensic examiners, database specialists, and students who want a reliable reference and teaching aid.
Whether you are analyzing SQLite files in a forensic case, validating database structures, or learning how varints work, Varint Calculator combines practical power with interactive education.

Fixed a bug where the K value for overflow calculation had the header value subtracted from it.
