We will have the following formats: • square: from 600 x 600 pixels to a maximum of 1936 x 1936 pixels. • landscape: from 600 x 315 pixels to a maximum of 1936 x 1936 pixels. • portrait: 1080 x 1350 pixels. • instastories: 1080 x 1920 pixels in jpg/png formats up to a maximum of 30 mb. On facebook: • profile: 320 x 320 • posts: 1200 x 630 pixels • page cover: 820 x 312 pixels • event: 1920 x 1080 twitter: • profile: 400 x 400 pixels • cover: 1500 x 1500 pixels • posts: maximum weight of up to 5mb. • .gif posts: up to 15 mb, but only 5 mb maximum on mobile devices. If, when designing, we create work spaces with these dimensions, according to each social network, we will have guaranteed that our E Commerce Photo Editing composition does not have an adaptability problem. Optimize the resolutions of your images when publishing on social networks. We have to know the format in which we work. For social media posts , the most suitable format will always be jpg. This format allows compression without losing quality. So it makes it ideal for a social network. Another format option will be png or gif. But be careful, the png is usually much heavier, since it stores capacity to save transparency. This is unnecessary data, due to the fact that social media posts have nothing to show behind them. Gifs can be interesting depending on the moment . Showing an animation of a design can be an attractive resource for the public. When using the gif format we have to optimize the resolution very well, so that it does not exceed in weight as if it were a video, but taking care of the quality of the image without pixelating. When designing for screens, the color space will always be rgb. It will be a mistake to consider our design with color spaces dedicated to printing such as cmyk, since, when publishing our design on networks, this format will be automatically changed and the color will be modified.
