Flowchart Maker
Draw flowcharts right in the browser with the classic notation's standard shapes: start/end (pill), process (rectangle), decision (diamond) and input/output (parallelogram). Connect blocks with arrows, add labels like "Yes" and "No" on decision branches, drag everything freely and export the result as a high-resolution PNG — with a fullscreen mode for working comfortably on larger diagrams.
Tap a shape to add it and drag to position. Select a block or an arrow to edit its text in the bar above. Decision arrows take labels like "Yes" and "No".
Your flowchart is saved in the browser automatically.
The notation's proper shapes
Each step type has its established shape — and its own color here, so the diagram reads from a distance: green for start/end, blue for processes, purple for decisions and amber for input/output. Each block's text wraps into lines automatically.
Smart labeled arrows
Arrows leave and arrive through the nearest border between blocks, and reposition themselves when you drag shapes around. Select any arrow to give it a label — essential on a decision's two branches ("Yes" / "No").
How to use
Tap a shape in the palette to add it and drag to position. To connect two blocks, click the dot on the side of the first and then anywhere on the second. Select a block or arrow and edit its text in the bar field. Use fullscreen for large diagrams and, when done, click "Download PNG".
Autosaved, exported in high resolution
Your diagram is stored in the browser — close and come back whenever. The export produces a double-resolution PNG, ready to paste into documents, slides and wikis.
Frequently asked questions
Is my flowchart saved on any server?
No. It is saved automatically only in your browser, with no sign-up and nothing sent to the internet.
Can I label a decision's arrows?
Yes. Select the arrow and type the label in the text field — "Yes", "No" or anything else.
What format is the diagram exported in?
PNG at double resolution (2400×1400), with a dark background that keeps texts readable in any document.
Does it work on mobile?
Yes. Adding, dragging, connecting and editing all work by touch, and the drawing area scrolls to fit larger diagrams.
