Pixlr and Fotor are popular cloud-based image editing software that offer basic editing tools and effects, making them a popular choice for casual users or those who do not require advanced features. Canva is primarily a graphic design platform, but it also offers basic image editing tools and is popular among social media marketers and small business owners for creating visual content.
