Some good comic strip makers online are BitStrip, Pixton, and MarvelKids. Each of these free websites allow users to access a gallery of comic style images and arrange the images in different ways, adding speech bubbles and other comic book effects.
BitStrip has sections for users to edit the panel layout and color, characters and other graphics, and add speech and action bubbles and special effects to the comic strip. Marvel Kids comic maker allows users to create comic books up to 22 pages in length with an art gallery of many Marvel characters and superheroes. However, there is no option to save work and return later. Finally, Pixton is one of the most dynamic and customizable comic strip makers, as it allows users to edit minute details of characters and fine-tune positioning and facial expression.
