Convert decimal numbers to Hexadecimal, Base64, GUID, and Binary in real time. 100% private, browser-side processing.
NUMBER TRANSFORMER
Bidirectional Hex, Base64 & GUID Converter
Key Features
Bidirectional Dual-Pane
Edit either side of the panel in real-time. Input decimal values on the left or paste Hex/Base64/GUID on the right to decode back instantly.
Multi-Format Support
Seamlessly convert between Decimal, Hexadecimal (0x), Base64 bytes, Binary sequences, and formatted 128-bit GUID structures.
BigInt Precision Engine
Built on JavaScript BigInt primitives to handle arbitrarily large integers and 128-bit byte representations without arithmetic overflow or precision loss.
Binary & Byte Operations
Inspect padded raw byte representations and bit layouts directly across hexadecimal and binary encodings for low-level debugging.
Instant One-Click Exports
Copy individual outputs or raw binary inputs straight to your clipboard with built-in toast alerts to accelerate your developer workflow.
Zero-Latency Local Privacy
Your data, numeric inputs, and transformed outputs stay completely on your machine. All calculations run 100% locally in your browser.
100% Client-Side Processing
Privacy is a feature. Your input values and converted data are calculated entirely in your browser using local JavaScript. We never upload, store, or see your data. It stays exactly where it belongs: with you.
