“I was looking at different companies, like Canva and Venngage and whatnot, and what really interested me about Piktochart was that they had just as many features, but I felt the price was just right in a sense; we were able to get more for our money, for less than the competitors.”

How to Create a Diagram
1. Log into your Piktochart account
Log into Piktochart (or sign up for the Free plan if you don’t have one already) and go to the dashboard. Once you’re there, go to the sidebar to the left and click diagrams.
2. Pick a diagram template
Our high-quality diagramming templates save you time and make your visuals and presentations look as professional as possible. You also have the option to start from a blank canvas if you prefer it.
3. Customize the diagram
Once you pick a diagram template, modify the colors, adapt the fonts, insert your own text, and even add your company colors to make your visual content fit your organization or brand. Ask for feedback and connect with different teams or other collaborators effortlessly.
4. Add images, icons, and other assets to the diagram creator
Make engaging visuals by adding images, icons, illustrations, and gifs with the drag-and-drop editor. When working on reports, you can add a map and link your Excel file or Google Sheet from Google Docs.
5. Download and share
Once you’re done visualizing data and customizing your visual, download it as a JPG, PNG (with the free account), or PDF (with the paid plans). You can also iterate and collaborate on the asset with your organization or team directly in Piktochart.
