Free flowchart maker
A free online flowchart maker, without sign up
TempCanvas is a browser flowchart tool for sketching a process, decision tree, or workflow. Place labeled nodes and drag connections between them. No account, installation, or cloud project is needed; ordinary editing stays in your browser.
Example: a simple approval workflow
How to make a flowchart in three steps
Add your nodes
Open the canvas and expand Flowchart in the top toolbar, or press S. Choose a rectangle for a process, a diamond for a decision, or a circle or ellipse for a start or end. Drag on the canvas to size the node.
Label and connect the steps
Double-click anywhere on a flowchart node to edit its centered title on the canvas. Drag one of its four connection points to another node, then double-click the line to add a connection title. Enter adds a line; Ctrl/⌘+Enter or clicking outside finishes; Esc cancels. Connections and their titles follow the nodes.
Style and save the diagram
Set border, background, and text colors in the bottom panel. Select a connection to change its color or delete it; drag an endpoint to reconnect it. Download a PNG to add the finished flowchart to a document or message.
Flowchart symbols: process, decision, start and end
Rectangles commonly represent actions, diamonds mark questions or branches, and circles or ellipses can mark start and end points. Arrows show the direction of the workflow. These node types are separate from the ordinary drawing shapes and include centered titles and four connection points.
Connections that follow your nodes
Connections attached to nodes use automatically routed bends and rounded corners. You can move and resize nodes using their four corner handles. A bound connection can be selected, recolored, deleted, or reattached by its endpoints; its whole line cannot be dragged away from the nodes. Automatic routing does not arrange the nodes for you.
For quick workflows and decision trees
Map an approval process, a customer support handoff, a simple algorithm, or a yes/no decision. Combine flowchart nodes with freehand notes and pasted images on the same canvas. TempCanvas is a manual diagram editor; it does not generate flowcharts from prompts or code.
Local recovery and PNG export
The current diagram is stored in this browser for recovery after a refresh. Download a PNG for a copy you can share; clearing browser data can remove the local drawing. Live presentation Beta is optional and shares the whole canvas with read-only viewers when you start it. There is no simultaneous editing or cloud document storage.
Is this flowchart maker free and available without sign up?
Yes. Open TempCanvas in your browser to draw a flowchart without an account, payment, download, or installation.
How do I connect flowchart nodes?
Select a flowchart node and drag from one of its four connection points to another node. The connection stays attached when you move or resize the nodes. Drag a line endpoint to reconnect it.
What are the flowchart keyboard shortcuts?
S opens the flowchart menu. Shift+R selects a process rectangle, Shift+D a decision diamond, Shift+O a circle, and Shift+E an ellipse. L selects a line and A an arrow. R and O still select ordinary drawing shapes; number keys 1–4 do not select nodes.
Can I export a flowchart or edit it with a team?
You can download a PNG and export canvas data for later import. Ordinary editing is local and limited to one editor. Live presentation Beta lets others watch in read-only mode; it does not support team editing.
Does it generate or automatically lay out flowcharts?
No. You place and label the nodes yourself. Connections route automatically between nodes, but TempCanvas does not generate diagrams from text, execute workflows, or automatically lay out the whole diagram.
