If you find that you want to increase the quality of your JPEG, please follow the steps below:
1. Click File Export when in your design.
2. Make sure Export to JPEG is selected.
3. Under JPEG settings, increase the height and width numbers.
4. Please note that you will have to use actual resolutions and not just random numbers.
For example, 3840 x 2160 is the standard 4K resolution.
5. It's also worth making sure that your JPEG quality is set to 100.
6. Lastly, be sure that you have selected a higher render in the render setting section.
Either Presentation, Presentation Plus or Publish are ideal.
