PNG and GIFF
Convert it to a format that does not support transparency (for example jpeg) or use a tool to edit the transparent pixel value.
It is an image file, not video. GIF file format support more pictures in one file to create and view it as short animation, but this not a video.
A flattened image has only one layer. After the image is flattened, it has the same appearance it had before. The difference is that all of the image contents are in a single layer without transparency. If there are any areas which are transparent through all of the layers of the original image, the background color is visible. By flattening an image we introduce significant changes to the structure of the image. It is normally only necessary when you would like to save an image in a format which does not support levels or transparency (an alpha channel).
Only GIF images allow animation. There is APNG format, but in some browsers it displays it as a static image.
GIF image is a Graphics Interchangable Format. The interchangeable part of it's name means you can have a series of images "storyboard" shown as a mini movie in a .GIF image file.
.Gif is a file format itself. Gif files are normally short animations or images with short 5 second effects. Other common image files are: .Jpg and .Png
Yes, Adobe Photoshop does support GIF images. GIF (Graphics Interchange Format) is a popular image format that supports both static images and animations. In Photoshop, you can open and edit GIF files just like any other image format. You can also create and edit GIF animations using Photoshop's animation tools. Thanks!
Photoshop has ties with other Adobe software for media editing, animation, and authoring. The .PSD (Photoshop Document), Photoshop's native format, stores an image with support for most imaging options available in Photoshop. These include layers with masks, color spaces, ICC profiles, transparency, text, alpha channels and spot colors, clipping paths, and duotone settings. This is in contrast to many other file formats (e.g. .EPS or .GIF) that restrict content to provide streamlined, predictable functionality.
Normally delete the background in the image then when saving, save with the transparent option checked. This will give you a transparent background. PNG is different than GIF format because with PNG you get 256 levels of transparency which allows you to smoothly blend your image to the page background on a webpage. GIF has only one level of transparency so you get a pixelated edge to your image.
most good image editors can make or edit both formats - they are both similar but each has advantages - gif can be used to make animations and has one level of transparency either on or off - png can have 256 levels of transparency and some image editors can work with pngs in millions of colors gif was the original internet image format but it was copyrighted and the creeps that designed it wanted to start charging everyone that used gifs a fee to do so - that is why png format was created, to give a free image format for the internet - but the attempts to collect fees for gif use didnt work and jpgs came along so the png format has been mostly neglected - but png format is a good one and all browsers as far as i know still support it
You can format using an image editor as GIMP or Photoshop, they are programs optimized exactly for this purpose. Some image converters support also a limited set of image processing operations.
