Simple Podcast Cloud will help you create quality, effective artwork the first time around, so you don't waste time remaking your design. 

Adobe Spark's (Free Plan) lets you create a custom-sized image and offers a wide selection of various templates, text styles, and pre-made color pallets to spark your creativity.

To get started, create an Adobe account. Click the + sign at the top left of the page and select Custom Size Graphic and enter your dimensions. 

Important Note:

The minimum podcast artwork size used to be just 300 x 300 pixels. Over the years, this standard has increased to the current 1400 x 1400 pixels minimum, and Apple's size standards may increase again in a few years.

To avoid having to redo your artwork in the future, make it future proof by submitting a larger image closer to the 3000 x 3000 pixels max. This way, your podcast is good to go if the standard rises again!

Once you're in the creator page, select the Add + button to upload your image and overlay it with custom effects and text, or browse hundreds of free templates and icons.  

In need of a little inspiration?

Try Spark's step-by-step logo maker and let the tool generate some ideas for your show's branding. It won't create podcast art for you, but it can get the ball rolling if you have a creative block!

When you're done with your design, selected Download at the top right of the screen and save the file as a .jpg or .png.
