The SVG format is a flexible, script oriented format so it can be used in interactive web pages. SVG ( Scalable Vector Graphics) is an open source standard for an all-purpose vector graphics format. PNG works very well in web browsers and on screen but is rarely suitable for printing.Д¬ommonly used file formats capable of storing raster and vector graphics are SVG, EPS and PDF. PNG is particularly useful for presentation slides thanks to the possibility of having a transparent background in the image that helps fit it seamlessly into a design.

PNG is best suited to store images with large, uniformly coloured areas but it is appropriate even for complex images like photographs вЂ“ where JPEG is the traditional choice вЂ“ thanks to its lossless compression. The PNG file format supports RGB colour and transparency.

PNG ( Portable Networks Graphics) format was created as a free, open-source alternative to GIF. Due to GIFвЂ™s widespread support by image viewer software, it is still commonly used to provide image animation effects, despite its low compression ratio compared to modern video formats. Similarly to the TIFF format, it uses the LZW compression. It performs best when storing graphics with few uniform colours, such as simple diagrams, logos, and cartoon type of images. Furthermore, GIF supports multiple images so it can be used for image animation. GIF ( Graphics Interchange Format) image format is a small size format for images limited to 256 colours (so called indexed-colour images) where one of the colours can be semi or fully transparent.

A version of the TIFF format, the OME TIFF format tries to establish itself as a standard storage format for microscopy imaging. However, the TIFF format is not widely supported by web browsers and remains more common in the printing business. As TIFF supports both RGB and CMYK colour models, it could be in principle useful for both printing and web destinations. TIFFs can be losslessly compressed with LZW compression which tends to be most effective for images composed of uniform areas of a single colour, but lacks performance for complex photographic images. TIFF sizes can be substantial so a compression is often required. As TIFF supports multiple images, it can be used for image stacks. TIFF or TIF ( Tagged Image File Format) format is very flexible as it supports both CMYK and RGB colour models and, in addition, allows for transparency (which is enabled by a so called alpha channel). As the RGB colour model is meant for on screen rendering, JPGs are best suited for web and screen usage. JPG format is most adapted to complex images like photographs and performs very poorly for line art images, simple plots and diagrams. For example, if you have an 3000-px-wide image and you need a 900-px-wide preview image and a 150-px-wide thumbnail image, then create both images starting from the 3000-px one instead of scaling down first to 900px and from 900px to 150px. Therefore, if it is necessary to create different sizes of JPG images, it is better to scale the same high resolution file for each of them. However, JPG file quality deteriorates over time when repeatedly edited and saved again. Compression does not necessarily affect the imageвЂ™s quality if it is applied moderately. JPGs are routinely compressed in a lossy way which enables to considerably decrease the file size. JPG or JPEG ( Joint Photographic Experts Group) format can handle only RGB colour model and does not allow for transparency. LetвЂ™s have a closer look at image formats first. Here is a quick visual overview for the most commonly used formats: A file format on the other hand is a format that can contain raster image data but also other elements like editable text or vector graphics. The image format contains data about every pixel in the image and the image metadata like the creation date and camera settings, for example. To clarify one thing up-front: a digital image format is a storage format for a bitmap or raster graphics. One file format to rule them all? вЂ¦ Nope!
