Essential file formast you will use.
EPS
Encapsulated Post Script. This is a resizable file format that is commonly used for vector designs. Due to its high quality, it’s commonly used with print elements such as logos, business cards or brochures.
Portable Document Format developed by Adobe that can be universally downloaded and viewed by any computer. PDFs are most suitable for sharing previews of work and are universally viewable. It is also the preferred method for delivery to printers.
SVG
Scalable Vector Graphics is a web-friendly vector file format. As opposed to pixel-based raster files like JPEGs, vector files store images via mathematical formulas based on points and lines on a grid. This means that vector files like SVG can be significantly resized without losing any of their quality, which makes them ideal for logos and complex online graphics.
PSD
PhotoShop Native Format
JPEG
Joint Photographic Experts Group, the most widely used raster file type for web-based designs. JPEGs are compressed files that load quickly. You’ll typically see them used for emails, banner ads, online photos, and pretty much anything else online. Unlike GIFs, they cannot have a transparent background (a white background will be added automatically).
GIF
Graphics Interchange Format is a raster file format that supports animation and transparency. They can only display up to 256 colors, allowing for very small file sizes
PNG
Portable Network Graphics, a web-based format that does not lose quality when compressed. These files were created to improve on the quality of GIF files. Often used when transparency is needed.
ZIP
Is a format that compresses files (or multiple files together) for easy transfer or storage.
