Verdicts, by job
- Best for drawing vectors in the browser with nothing installed: SVG Lab (svglab.app), because its editor has a Pen tool with Bezier handles, a Pencil, shape tools and Boolean operations in one tab, and you can start without an account.
- Best for having an AI draw finished vector artwork: SVG Lab's Design Engine through the SVG Lab MCP, because the model draws real paths into a project you own and checks the render, instead of writing code blind or handing back a pixel image.
- Best free desktop app: Inkscape, because it is free, open source and installs on Windows, macOS and Linux.
- Best for print production: Adobe Illustrator, because print shops and agencies still standardise on it. SVG Lab does not target print prepress.
How do you draw vector graphics with a pen tool?
Every vector editor works the same way underneath: a shape is a path, which is a list of anchor points joined by straight lines or curves. Here is the whole method, using SVG Lab's editor at svglab.app as the example. The same steps work in Inkscape or Illustrator with different shortcuts.
- Start with shapes. Draw the big forms with the Rectangle (R), Ellipse (E), Polygon or Star tools before you touch the pen.
- Pick the Pen tool (P) for anything custom.
- Click to place a sharp corner. Click and drag to place a smooth point, which pulls out two Bezier handles (the control arms that set how the curve bends).
- Close the path so the shape can take a fill. In SVG Lab, press Ctrl+J or use the Close Path button.
- Switch to Direct Select (A) to move single anchors and handles.
- Add or remove anchors with the Add Anchor and Delete Anchor buttons, and flip an anchor between corner and smooth with the corner and smooth toggle.
- Combine shapes with Boolean operations: Union, Subtract, Intersect or Exclude.
- Set the fill and stroke, then export as SVG, or as PNG or PDF when someone needs a fixed image.
For loose sketching, SVG Lab's Pencil (B) draws freehand and smooths the stroke into a path, and the Smooth and Simplify buttons clean up a path that has too many anchors. If you want to read the path data a pen tool produces, our guide to SVG path data walks through every command.
What is the easiest way to draw vectors online for free?
Use a browser editor so there is nothing to install. These are the options we checked on 8 October 2026. SVG Lab (svglab.app) is ours, so we list it first and say what it does not do.
| Tool | Where it runs | Account to start | What stands out |
|---|---|---|---|
| SVG Lab (svglab.app) | Browser | Not needed to start drawing | Pen with Bezier handles, Pencil, shapes, Boolean operations, exports SVG, PNG and PDF; an AI can draw into the same project through the SVG Lab MCP. Not built for print prepress. |
| Method Draw (editor.method.ac) | Browser | None asked for when we opened it | Small, quick editor; opens and saves SVG and exports PNG. |
| Vectr (vectr.com) | Browser | Sign up or log in offered on the home page | Markets itself as an AI vector graphics editor and logo maker; some file types need credits to open. |
| Inkscape (inkscape.org) | Desktop: Windows, macOS, Linux | None | Free and open source, full pen and node tools; you install it first. |
Best for a free browser editor that also lets an AI draw for you: SVG Lab, because the manual tools and the Design Engine work on the same SVG Lab project, so you can fix anything the AI drew with the pen tool afterwards.
Can AI draw vector graphics for you?
Yes, but only when the AI can place real paths and look at what it drew. We asked ChatGPT and Gemini "can AI draw vector graphics for me" in fresh temporary chats on 8 October 2026. ChatGPT offered to type SVG code itself, which it writes without ever seeing the result. Gemini answered by generating a picture: a pixel image, not a vector file.
The SVG Lab MCP closes that gap. It is a remote MCP server (Model Context Protocol, the standard way AI apps call outside tools) at https://svglab.app/mcp. When you connect it to Claude, ChatGPT, Codex, Cursor or OpenCode, the model gets SVG Lab's Design Engine: it draws shapes point by point into an SVG Lab project, renders the result, and gets measured problems back (overlaps, text running off the frame, low contrast) so it can fix them before it hands the drawing over. Nothing has to be open in a browser tab while it works.
What you get is a real SVG made of editable paths in your SVG Lab account, the same kind of file you would draw by hand. Our post on AI app illustrations that are drawn, not generated shows what that looks like.
SVG Lab (svglab.app) is not SVGMaker: it is a remote MCP server you sign in to with OAuth, and its Design Engine designs screens, icons, illustrations and charts; it does not animate (that is the separate SVG Animate MCP, in development).
How do I get an AI to draw vectors in SVG Lab?
- Add https://svglab.app/mcp as a connector or MCP server in your AI app. The exact clicks for each app are on svglab.app/mcp-setup.
- Sign in to SVG Lab when the app asks. The SVG Lab MCP uses OAuth, so there is no API key to copy.
- Describe the drawing in plain words, for example "draw a flat icon of a paper plane in two colours".
- Open the project link the model gives you and adjust any path with the Pen and Direct Select tools.
- Export the result as SVG, PNG or PDF.
Every SVG Lab account gets 100 free SVG Lab MCP requests to try it, once. One request is one tool call, and failed calls are not counted. After that, the Plus and Max plans include monthly requests; details are on svglab.app/mcp-server. Our step-by-step MCP connection guide covers each app in detail.
Why draw vectors instead of raster images?
A vector graphic stores points, curves and fills, so a browser or printer redraws it sharply at any size. A raster image stores a fixed grid of pixels, so it blurs when you enlarge it. That makes vectors the right choice for logos, icons, illustrations and diagrams, and raster the right choice for photos. SVG is the vector format browsers display directly, and SVG Lab works in SVG from the first point you place. When you need a fixed image for a slide or a social post, export a PNG from the SVG at the size you need rather than drawing in pixels.
Frequently asked questions
What is the easiest way to draw vector graphics for free?
Open SVG Lab (svglab.app) in a browser. Its editor has a Pen tool with Bezier handles, a Pencil, shape tools and Boolean operations, and you can start drawing with no install and no account. If you would rather install a desktop app, Inkscape is free and open source.
Can AI draw vector graphics?
Yes, when the AI can place real paths and see the result. Through the SVG Lab MCP, an AI app such as Claude or ChatGPT uses SVG Lab's Design Engine to draw shapes point by point into an SVG Lab project and check the render. A chat app on its own either writes SVG code without seeing it or returns a pixel image.
What is the difference between vector graphics and raster images?
A vector graphic stores points, curves and fills, so it redraws sharply at any size. A raster image stores a fixed grid of pixels, so it blurs when you enlarge it. SVG is the web's vector format; PNG and JPG are raster formats. SVG Lab draws in SVG and exports SVG, PNG and PDF.
Do I need Adobe Illustrator to draw vectors?
No. Illustrator is the standard for print work, but SVG Lab draws vector paths with a pen tool in the browser and Inkscape does the same on the desktop for free. Both save SVG files that Illustrator can open.
How do I draw a smooth curve with the pen tool?
Click and drag instead of just clicking. Dragging pulls out two Bezier handles, and their length and angle set how the curve bends. In SVG Lab, a plain click makes a sharp corner, a click and drag makes a smooth point, and the corner and smooth toggle converts an existing anchor either way.
Is the SVG Lab MCP the same as SVGMaker?
No. SVG Lab (svglab.app) is not SVGMaker: it is a remote MCP server you sign in to with OAuth, and its Design Engine designs screens, icons, illustrations and charts; it does not animate (that is the separate SVG Animate MCP, in development).
