Bitcointalk Signature Designer

Build signatures visually inside a Bitcointalk-style canvas, keep the raw BBCode synchronized live, and preview exactly how close you are to the forum’s character and height limits.

Forum guardrails
~4000 chars, ~42px visible height, ~620px signature width.
Editing modes
Click and type directly in the visual canvas or edit the raw BBCode below.
The toolbar is filtered by rank. Unsupported tags already present in your BBCode are shown as plain text or flattened in the visual canvas and preview.

Character counter
Bitcointalk counts everything in the signature field, including spaces and line breaks.
0 / 4000
Forum count includes spaces and line breaks.

Height warning
Taller signatures are often clipped. The preview uses a visible cutoff line around 42px to mimic Bitcointalk behavior.

Link inserter

Create [url] or [url=...] quickly.

Use full HTTPS URLs. If link text is blank, the tool uses plain [url]https://...[/url].

Image inserter

Images are constrained to 42px tall.

Bitcointalk users often host signature images on stable HTTPS hosts such as TalkImg. Keep banners compact to avoid clipping.

Table builder

Critical for layout work and pixel art.

Tables are one of the most reliable ways to align columns, badges, and tiny block-character art in Bitcointalk signatures.

Visual editor

This is the WYSIWYG canvas. Click inside, type directly, and use the toolbar to apply BBCode-compatible formatting.

Tip: The visual canvas is synced to the raw BBCode editor below. If you prefer typing tags manually, edit the BBCode and the visual canvas will refresh automatically.

Raw BBCode editor

Paste existing code or fine-tune output by hand. The visual canvas and preview stay in sync.
