About Blob Maker
Blob Maker generates organic blob shapes for websites and designs: the soft, fluid forms behind hero portraits, section decoration, cards, posters and slides. Pick one of six blob styles - classic round, wobbly, melty, scalloped, spiky or ink-splat - then shape the silhouette with the points and distortion sliders. Where most blob generators stop at a flat color, Blob Maker paints the blob eight different ways: solid, linear or radial gradients, concentric nested copies, outline rings, a single outline, stripes cycling through your palette, or a pattern from a 20-pattern library - dots, lines, crosshatch, bricks, scales, zigzags, waves and more, each with scale and angle controls - and stacks up to six layers spreading out behind the blob for the layered depth look, with spread, twist and contrast controls.
Every blob is seeded, so the Reshape button explores endless new shapes with the same settings while the sliders keep doing exactly what they say. Colors come from a palette of two to six stops - fifteen curated palettes give a designed look in one click, or build your own color by color - over a custom or fully transparent background. For wave-shaped section dividers instead of blobs, try our Wave Maker - or browse the other Create tools.
How it works
-
Pick a blob style
Start the app and choose round, wobbly, melty, scalloped, spiky or ink-splat - then shape the silhouette with the points and distortion sliders.
-
Fill and stack it
Pick a fill - gradients, rings, stripes or one of 20 patterns - a curated color palette, and optionally a layered stack with spread and twist. Randomize and Reshape explore new looks in one click.
-
Export and use anywhere
Save as scalable SVG, PNG at any size - with presets for social posts, banners and wallpapers - or a ready-to-paste CSS class. Everything copies straight to the clipboard too.
What can I use the blobs for?
Hero and section backgrounds, image masks and portrait backdrops, card and button decoration, slide and video-call backgrounds, social media graphics, stickers, print accents or wallpapers. The SVG export is a real vector, so it stays crisp at any size and is easy to recolor in design tools like Figma, Illustrator or Inkscape. Everything you generate is yours to use freely, for personal and commercial projects alike - no attribution required.
Frequently asked questions
Is Blob Maker free?
Yes, completely free, with no account, watermark or usage limits. The blobs you make are yours to use in your own work, commercial projects included - see our License.
What kinds of blobs can I make?
Six styles: classic smooth rounds, wobbly edges with fine detail, asymmetric melty forms, scalloped cloud silhouettes, sharp spiky splashes and ink-splat lobes. Each is shaped by points and distortion sliders plus its own controls, filled eight different ways - solid, linear or radial gradients, nested copies, rings, outline, stripes or a pattern from a 20-pattern library - and stacked up to six layers deep.
How is this different from other blob generators?
Beyond the classic random blob, Blob Maker adds multiple silhouette styles, eight fill modes, layered stacks with spread and twist, curated multi-stop palettes, seeded reproducible shapes, social-size previews and PNG, SVG and CSS export with copy to clipboard - all free and entirely in your browser.
Which format should I save in?
SVG keeps the blob as vector art that scales to any size without quality loss - ideal for websites and design tools. PNG gives you an image at exactly the size you choose, with presets for common social and wallpaper sizes; a transparent background is preserved. CSS gives you a ready-to-paste class with the blob embedded as a data URI - drop it onto a section or card element. Every format can also be copied straight to the clipboard.
Is anything uploaded to a server?
No. The blobs are generated and exported entirely in your browser; nothing is stored when you close the page.
Which browsers are supported?
All modern browsers: Chrome, Edge, Firefox and Safari, on desktop and mobile.
