Diagram Studio

PixelOkay Diagram Studio helps you build flowcharts, mind maps, organizational diagrams, and technical illustrations directly in your browser. Arrange shapes, connect processes, customize styles, and save an editable project to reopen later.

How to create a diagram

  1. Select a shape or start from a template.
  2. Double-click to edit text; drag shapes to position them.
  3. Connect nodes using connection handles or select two shapes and choose Connect.
  4. Export an SVG, PNG or editable project when finished.

Diagram files are edited locally in your browser without uploads. Browser autosave can be cleared by storage policies, so download editable project backups. Single-page compressed or uncompressed draw.io files with supported basic shapes and connectors can be imported; complex styles, embedded media and multiple pages are not supported.

Using Diagram Studio

Choose shapes or a starter diagram, connect the steps and edit their labels or appearance. Download a project file so the diagram remains editable after you leave the browser.

The diagram engine is self-hosted with the tool. Browser storage is not a guaranteed backup, imported formats support a bounded subset, and browser printing is separate from a downloadable PDF export.

Choose an editable diagram or a visual export

Practice: a small support flowchart

  1. Create three labeled steps: Request, Review and Reply. Connect them in order.
  2. Adjust the labels and arrangement so another person can follow the flow.
  3. Save a project file before exporting an image. Keep the project independently of browser recovery storage.

This is an authored diagram exercise, not a tested project or a generated export.

Diagram import questions

Can I open any draw.io file directly?

Single-page draw.io XML files with basic shapes, labels, geometry and connectors are supported, including compressed pages when the browser supports raw Deflate. Multi-page files, images, arbitrary HTML labels, advanced routing and other unsupported elements may be rejected or simplified. Keep the original draw.io file as a backup.

Why might a large PNG export fail?

Raster exports have dimension and memory limits. Try a smaller diagram or a suitable zoom level, or use SVG for a vector handoff. Keep the editable project before changing the view or simplifying the diagram.
