Extensive shape library

Drag and drop from a thorough library of shapes including network diagrams, UML, user interface, process flow, entity-relationship, floor plans, and basic shapes.

Upload your own /images

Import your own /images, like logos and backgrounds, to complement your diagrams. Gliffy Premium accounts include unlimited space for image uploads.

Save as JPG, .PNG, .SVG

Easily import a picture of your diagram into another document in a desktop or online application, or open it with an illustration application.

Large drawing area

Why confine yourself? Gliffy has a large default drawing area, 5000x5000 pixels. When you're ready to publish or print, Gliffy automatically resizes the area to match the perimeter of the diagram.

Printing

Easily print your diagrams.

Auto-line connectors

Connect shapes with lines and the lines will automatically shift when you move the shapes.

Auto-centering on zoom

When you zoom in, Gliffy keeps the image centered, making it easier to navigate.

Document manager with tagging and preview

Just like your "My Docs" folder, Gliffy helps you organize and find your diagrams. Assign tags to your documents to make them easier to sort and search. See a thumbnail of your documents so you can find one quickly without opening numerous files.

Lock shape

When you lock a shape, it stays put while you move other objects on the screen.

Color and gradient fill options

Choose colors and gradient fills to make your diagrams easy to read and professional-looking.

Auto-formatting

Gliffy remembers your last color and text formatting so you can repeat the formatting more quickly on additional objects.

No Gliffy logo

With a Gliffy Premium Account, your diagrams will not contain the Gliffy logo or wording.
