Cyber Grid Background Generator

Make a retro-futuristic anime grid for synthwave edits, sci-fi thumbnails, virtual idol graphics, or tech product shots. Horizon, spacing, perspective, line width, and glow all feed the same canvas renderer used for PNG export.

PNG sequence and animated PNG keep the alpha channel. WebM is opaque and records in real time.

PNG export runs entirely in your browser. Nothing is uploaded.

Best uses

Where signal grid backgrounds work best

Sci-fi thumbnails

Place a character, gadget, or logo in front of the horizon line for cyberpunk video thumbnails and stream covers.

Virtual idol graphics

Use a low horizon and bright glow for stage-like backgrounds behind VTuber, avatar, or music artwork.

Tech product shots

Reduce glow and line width to make a cleaner grid behind phones, laptops, keyboards, or app screenshots.

How it works

Canvas rules behind this template

The template paints a dark gradient sky, adds a soft neon radial wash, then draws the horizon and perspective grid lines.

Horizon Y places the vanishing line, while perspective changes how quickly horizontal grid rows compress with depth.

Glow applies canvas shadow blur to the grid strokes without changing the uploaded subject layer.

Tips

Quick ways to improve the PNG

Keep the subject near the vanishing point when you want the grid to frame it naturally.
Turn glow below 0.4 for cleaner product mockups and above 0.7 for retro anime energy.
Use wider grid spacing on portrait exports so the floor does not become too busy.

Questions

Signal Grid FAQ

Can I move the cyber grid horizon?

Yes. Horizon Y places the vanishing line higher or lower so your subject can sit inside the perspective grid.

Can I turn the glow down?

Yes. Glow ranges from clean line art to bright neon bloom.

Is the grid an external image?

No. The grid is generated locally with canvas drawing commands.
