Sometimes, you find a drawing or similar image useful for a Wikipedia article, that was saved as a JPEG but should have been saved as a PNG.JPEG is good for images where the color changes fluidly throughout the image, like in a photograph, whereas PNG files are good for images with relatively few colors, such as a drawing of a flag, a chart, or a map; note that sometimes SVG is better.
Photopea (/ ˈ f oʊ t ə ˈ p iː / FOH-tə-PEE) is a web-based photo and graphics editor. It is used for image editing, making illustrations, web design or converting between different image formats. Photopea is advertising-supported software. It is compatible with all modern web browsers, including Opera, Edge, Chrome, and Firefox. [5]
Many image file formats use data compression to reduce file size and save storage space. Digital compression of images may take place in the camera, or can be done on the computer with the image editor. When images are stored in JPEG format, compression has already taken place.
The GNU Image Manipulation Program, commonly known by its acronym GIMP (/ ɡ ɪ m p / GHIMP), is a free and open-source raster graphics editor [3] used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is extensible by means of plugins, and ...
an image that is not rectangular can be filled to the required rectangle using transparent surroundings; the image can even have holes (e.g. be ring-shaped) in a run of text, a special symbol for which an image is used because it is not available in the character set, can be given a transparent background, resulting in a matching background.
JPEG compression works better on slightly blurred images, so don't sharpen the images too much as it will result in a higher footprint. Always work from the original image and not from the already saved JPEG file, as quality gradually decreases the more you save it; this is known as digital generation loss .
The compressed files can be opened as normal image files. Since version 4, the image data can be compressed by zlib instead. The XCF file format is backward compatible (all versions of GIMP can open earlier versions' files) and in some cases, forward compatible. For example, GIMP 2.0 can save text in text layers while GIMP 1.2 cannot.
[1] A number of vector graphics editors exist for various platforms. Potential users of these editors will make a comparison of vector graphics editors based on factors such as the availability for the user's platform, the software license, the feature set, the merits of the user interface (UI) and the focus of the program.
