This guide focuses on the practical decisions behind image editing: pixel dimensions, file formats, compression settings, browser support and the final destination of the image. The goal is to help you choose a workflow based on the actual requirement rather than simply producing the smallest possible file.
PNG in practical terms
PNG is a lossless image format and can preserve transparency. It is often useful for screenshots, logos, interface graphics and illustrations where sharp edges or exact pixel information matters. Its files can become large when used for detailed photographs.
JPG in practical terms
JPG uses lossy compression and is commonly used for photographs. The encoder discards some information to reduce file size, so quality settings matter. JPG cannot store transparency.
Which format for a photograph?
JPG is a practical starting point when compatibility and compact photographic files matter. WebP is another option for web delivery when supported. Compare the actual outputs because image content strongly affects the final file size.
Which format for transparency?
If an image genuinely needs transparent pixels, PNG is a common choice. Converting a JPG to PNG does not create transparency because the JPG has already flattened its background.
Which format for screenshots?
PNG is often useful for screenshots containing text, sharp interface elements and flat colors. The priority is preserving readable edges rather than achieving the smallest possible file.
