How to Make a Flowchart Online for Free

Create a process flowchart, mind map, or UML sketch in your browser. Wikawe Canvas saves locally, needs no account, and exports PNG, SVG, or PDF.

Step-by-step

  1. 1

    Open the free online flowchart maker

    Go to Tools → Wikawe Canvas, or open /en/tools/online-flowchart-maker. The editor loads in the page — no download.

  2. 2

    Add process and decision shapes

    Drag Start/End, Process, Decision, and Database onto the canvas. Start from a template if you want a head start.

  3. 3

    Connect the steps

    Draw arrows between ports. Elbow connectors stay attached when you move boxes. Label Yes/No on decision edges.

  4. 4

    Export PNG, SVG, or PDF

    Download canvas contents (not a screenshot of the UI). Use Export JSON as a backup if you switch browsers.

Overview

A flowchart maker online should let you drop shapes, connect steps, and export — without installing Visio or creating an account. Wikawe Canvas is a free browser flowchart creator for process maps, mind maps, UML class sketches, and software architecture on one infinite canvas.

Product, support, and engineering teams draw registration flows, checkout, CI/CD, and incident playbooks. Students sketch UML. Founders map architecture. Doing that in the browser — with local save — is faster than a desktop suite for drafts you will export to PNG or PDF.

When to use an online flowchart maker

Product, support, and engineering teams draw registration flows, checkout, CI/CD, and incident playbooks. Students sketch UML. Founders map architecture. Doing that in the browser — with local save — is faster than a desktop suite for drafts you will export to PNG or PDF.

Common use cases

People search for how to make a flowchart online when they need a fast result without installing software. Mapping a user registration or checkout process with Yes/No decisions. Brainstorming a mind map from a central topic, then exporting SVG for slides. Sketching UML classes or a server–API–database architecture for a design doc.

wikawe handles these scenarios in seconds — open the tool, paste or upload, and copy the result. No account required.

Why browser-only processing matters

Many free online converters paste your code, images, or designs to a remote server. That is a poor fit for unpublished UI, API payloads, or personal photos.

wikawe utility tools run in your browser with JavaScript. Nothing is stored on our servers — open the tool, work locally, and copy or download the result.

Troubleshooting tips

If a result looks wrong, refresh and try a smaller sample first. Clear the field and paste again to rule out hidden characters.

Use an updated Chrome, Edge, Safari, or Firefox. For image tools, very large files may need more memory — close unused tabs first.

Pro tips

  • Use elbow connectors for flowcharts; keep decision labels short (Yes/No).
  • Mind maps use Topic, Subtopic, and Branch shapes — or the mind-map template.
  • Paste Mermaid graph TD / flowchart LR to convert it into editable shapes.
  • Workspace at /workspace/diagram-maker is a larger canvas without the article below.

Frequently asked questions

Does wikawe upload my data to a server?+

No. Formatting, conversion, and generation run in your browser. Your inputs stay on your device (currency rates use a short public rates request only).

Do I need to sign up to make a flowchart?+

No. Open the page and start drawing. Documents auto-save in this browser (IndexedDB).

Is this the same as draw.io?+

No. Wikawe Canvas is a native Wikawe editor. It is inspired by browser canvas tools, not a copy of diagrams.net.

Can I also make mind maps and UML?+

Yes. The same canvas includes mind-map, UML, architecture, and network shapes plus Mermaid flowchart import.
