Soft, irregular blobs are the friendly backbone of modern landing pages — behind hero images, inside feature sections, framing avatars and testimonials. Drawing a good one by hand in a vector editor is fiddly; this generator creates them mathematically instead, scattering points around a circle and smoothing them into a closed organic curve. Randomise until a shape feels right, tune its complexity, choose a fill colour, and copy the SVG markup or download the file. Blobs earn their keep in the small moments of a design system: behind testimonial photos, inside empty-state illustrations, as the hover shape on pricing cards. Because the output is a single path, it recolours with one fill change and themes effortlessly — generate a family of blobs at the same complexity with different seeds and you have a coherent shape language for an entire site. Designers often save three favourites (gentle, medium, wild) and reuse them rather than randomising fresh shapes on every page.
Quick Answer: Click Randomise until you like the blob, adjust points and smoothness for a wilder or calmer shape, pick a colour, then copy the SVG code or download the file.

How to Use the SVG Blob Generator
- Click Randomise to generate a fresh blob shape.
- Raise Points for a more complex, wobbly outline; lower them for a calmer pebble.
- Adjust Smoothness to sharpen or soften the curves.
- Choose a fill colour that suits your design.
- Copy the SVG markup into your HTML, or download the .svg file.

- Copy-ready inline SVG and a downloadable file
- Free with no sign-up
Best Practices and Tips
- Blobs work best as backgrounds: place text or an image above the shape, not inside it.
- Low point counts (5–7) give modern, minimal pebbles; high counts feel playful and organic.
- Use your brand colour at full strength for hero sections, or pale tints behind content cards.
- Inline SVG (copy method) lets you recolour the blob later with CSS fill rules.
- Pair two overlapping blobs at low opacity for a soft gradient-like effect without images.
- For photo masks, keep complexity low and smoothness high — busy edges fight the photo’s subject; a calm four-to-five-point blob frames faces far better.
Common Mistakes to Avoid
- Expecting the same random blob twice — note the seed behaviour: re-rolls are intentionally fresh each time.
- Stretching the SVG non-uniformly in HTML, which distorts the shape; keep the viewBox aspect.
- Using a busy blob behind body text, which hurts readability.
- Forgetting that downloaded SVG files reference no external assets — they just work anywhere.
Frequently Asked Questions
How are the blobs generated?
Points are placed around a circle at varying radii, then connected with smooth quadratic curves through their midpoints to form a closed organic path.
Can I edit the blob after downloading?
Yes. The SVG is ordinary markup: open it in any vector editor, or tweak the path and fill attributes directly in code.
What size is the generated SVG?
It uses a 200×200 viewBox and scales to any display size without losing sharpness, like all vector graphics.
Can I use the blobs commercially?
The shapes are generated mathematically in your browser; you are free to use the output in personal and commercial designs.
Is this generator free?
Yes — free, unlimited and no sign-up required.
Can I animate the blob shape?
Yes — morphing between two paths works smoothly when generated with the same point count; keep complexity fixed and randomise the seed for each keyframe state.
