Manga Background Maker

Manga Speed Lines Generator

Create fast motion backgrounds for anime edits, comic panels, and high-energy thumbnails. Speed lines are rendered from seeded canvas strokes, so changing the seed gives a new layout while export remains deterministic.

Boiling loop: the background reseeds each frame while your subject stays still.

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.

How to use

Best uses

Where rush lines backgrounds work best

Action thumbnails

Use radial speed lines behind a character or product to signal motion, chase scenes, attacks, or fast reveals.

Panel transitions

Switch direction to left, right, top, or bottom when a manga panel needs a clear sense of travel.

Creator overlays

Export a clean PNG background for video thumbnails, meme panels, or social posts that need speed without animation.

How it works

Canvas rules behind this template

The canvas draws seeded strokes from a direction or from a radial center, so the same seed recreates the same line layout.

Line count changes density, thickness changes visual weight, and length controls how far each motion mark travels.

Jitter adds hand-drawn variation without moving the uploaded subject layer.

Tips

Quick ways to improve the PNG

Use radial mode for impact, and horizontal or vertical modes for clear movement direction.
Lower jitter when you need clean graphic lines around product images.
Try a dark line color on a warm background for classic black-and-white manga energy with better web contrast.

Questions

Rush Lines FAQ

Can I make horizontal or vertical speed lines?

Yes. Direction can be left, right, top, bottom, or radial depending on the kind of motion you need.

What does the seed control?

The seed changes the randomized spacing and offsets while keeping the same parameters reproducible for PNG export.

Can I export transparent speed lines?

Yes. Turn on transparent background in the export panel to keep only the ink strokes with an alpha channel, ready for compositing.
