Online Timing Diagram Tool

Create publication-ready timing diagrams without installing software. WavePaint runs entirely in your browser, giving you professional waveform editing tools instantly.

Why Choose an Online Timing Diagram Tool?

Traditional timing diagram software requires installation, licensing, and often runs only on specific operating systems. An online timing diagram tool eliminates these barriers:

• No installation – Open your browser and start creating
• Cross-platform – Works on Windows, Mac, Linux, and Chromebooks
• No licensing hassles – No dongles, activation codes, or subscription management
• Always up to date – Automatic updates without downloads
• Access anywhere – Use from any computer with a browser

WavePaint: Professional Online Waveform Editor

WavePaint is a powerful digital timing diagram editor that works directly in your browser. Unlike text-based tools like WaveDrom, WavePaint offers an intuitive graphical user interface (GUI) that lets you draw waveforms visually, without writing JSON code.

WavePaint isn’t a limited web demo – it’s a complete timing diagram editor with all the features you need:

• Multiple signal types – Bit signals, vector buses, blank rows
• Visual drawing tools – Click and paint waveforms directly
• Arrows and annotations – Show timing relationships and add labels
• Markers – Highlight timing events with vertical markers
