SVG Shape Generator

This tool is a free application that allows you to easily generate SVG shapes like waves and blobs (organic circles) through intuitive slider operations. You can instantly create "wave dividers between sections" or "organic shapes placed behind hero images" — trends currently popular in web design — without needing dedicated design software.

The generated graphics are output as "SVG data", which is highly lightweight and maintains image quality even on high-resolution displays without deterioration. Inline code for direct HTML embedding, CSS code for background images, and Tailwind CSS utility classes are automatically generated, significantly improving frontend development efficiency.

Since all graphic generation processing is done entirely within your browser, it is safe to work in environments containing confidential information, and you are free to use the materials for both commercial and non-commercial purposes.

SVG (Scalable Vector Graphics)

Vector-format image data that expresses images using points, lines, and mathematical formulas. Unlike JPEG or PNG, it never becomes pixelated no matter how much you enlarge it, and the file size is very small, making it ideal for web design.

Blob

In the IT and design industry, it refers to an "amoeba-like organic soft shape". It is a highly popular design element recently used as a background accent on websites or as a clipping mask for photographs.

viewBox

An attribute specified in an SVG tag that defines the "canvas ratio and coordinates" for drawing the SVG image. By setting this properly, the image can flexibly scale up or down to fit the width of its container when embedded in HTML.

Tailwind CSS

A utility-first CSS framework that applies styles by writing class names directly in HTML. This tool can directly output code in Tailwind's `bg-[url('...')]` format, setting the Data URI converted SVG image as a background.

Perlin Noise

An algorithm that generates natural and smooth pseudo-random numbers. Inside this tool, a similar noise generation and interpolation algorithm is applied to calculate beautifully smooth, albeit randomized, curves for waves and blobs.

Q.Should I use PNG or SVG?

For web design, we recommend using SVG because it maintains high image quality regardless of resolution and has a very small file size. On the other hand, use PNG for systems that do not allow direct SVG uploads or for purposes like OGP images. PNGs downloaded from this tool are exported at a Retina-ready 2x resolution.

Q.How can I make the wave automatically scale to screen width?

When you use the generated SVG or CSS code, the wave is designed to automatically be responsive (scale to the screen width) by default. Internally, the SVG uses the `preserveAspectRatio="none"` setting.

Q.Are the generated shape data sent to a server?

No, they are not sent anywhere. All processes, from shape generation and SVG code output to PNG image rendering, are completed entirely within your browser (on your computer or smartphone). You can use it safely.

Q.Can I use the generated shapes for commercial purposes?

Yes, you can use the SVG shapes and PNG images created with this tool for both commercial and non-commercial purposes for free. No credit attribution is required.

Q.How do I use the generated SVG in a CMS like WordPress?

You can either use a plugin that allows direct uploading of SVG images to the media library, or directly paste the 'Inline' or 'CSS' code from this tool into your HTML/CSS editor screen.

Generated SVG shapes can be utilized in various web design scenarios. Below are representative use cases.
