Blob generator for colorful blur backgrounds

Tool powered by bbblurry on fffuel.

Free blob generator for colorful blur and blurry gradient backgrounds. Tune blur color, shape size, and opacity, then export SVG for glassmorphism and modern UI.

What is a blob generator for blur backgrounds?

A blob generator places soft, blurred shapes on a canvas so you can build colorful blur and blurry gradient backdrops without illustration apps. Run bbblurry by fffuel (https://www.fffuel.co/bbblurry/): add blobs, tune blur color and intensity, and export lightweight SVG for glassmorphism heroes, cards, and modals. Related workflows include Squoosh (/squoosh) for SVG-to-PNG conversion.

Generator features

Controls in the bbblurry editor on this page.

  • Blob shape canvas

    Add, move, and layer blurred balls to build a colorful blur composition.

  • Blur color per shape

    Set blur color on each blob so your backdrop mixes hues instead of a single fill.

  • Blur amount and size

    Dial blur intensity and stretch size X or Y for circle blur or wide soft glows.

  • Opacity and layering

    Stack shapes for a blurry gradient effect that stays subtle behind text.

  • Aspect ratio presets

    Export a blurry color background sized for square, portrait, or widescreen layouts.

  • SVG export

    Copy markup or save SVG, then open Squoosh when stakeholders need PNG.

How to create a colorful blur background

Three steps using the editor above.

  1. Step 1: Add blobs

    Place blurred shapes and assign a blur color to each one.

  2. Step 2: Tune blur and size

    Adjust blur amount, size X and Y, and opacity until the blurry gradient feels balanced.

  3. Step 3: Export

    Copy or save SVG. Use Squoosh when you need a raster file.

Design tips

Practical ways to get stronger colorful blur results.
  • 01

    Edge placement

    Keep blobs near corners and sides so the center stays clear for headlines and UI.

  • 02

    Pair blur colors

    Two or three related hues read as a smooth color blur; avoid too many competing accents.

  • 03

    Glassmorphism stacks

    Place your SVG behind a frosted panel—the blur color background adds depth without noise.

  • 04

    Circle blur scale

    Larger blobs with high blur amount create dreamy backgrounds; smaller ones add accent glows.

  • 05

    Reset and iterate

    Use reset to try new blob layouts quickly when exploring blurry gradient options.

Who uses colorful blur backgrounds?

Common projects that benefit from blob-based blur art.

  1. UI designers: Glassmorphism cards, modals, and dashboards with soft color blur.

  2. Web designers: Hero sections and feature blocks with blurry color atmosphere.

  3. Developers: Inline SVG backdrops that stay sharp at any viewport size.

  4. App designers: Onboarding and profile screens with circle blur accents.

  5. Marketers: Landing pages and slides that need modern blur without stock photos.

  6. Content creators: Stream overlays and thumbnails with a quick blob generator workflow.
