Image Format Guide
PNG (Portable Network Graphics)
PNG is a lossless format that supports transparency. It's ideal for logos, icons, screenshots, and graphics with text. PNG files are larger than JPEG but preserve all image data perfectly.
JPEG (Joint Photographic Experts Group)
JPEG is a lossy format optimized for photographs and complex images. It offers adjustable compression to balance file size and quality. JPEG doesn't support transparency.
WebP
WebP is a modern format developed by Google that provides superior compression for web images. It supports both lossy and lossless compression, as well as transparency, making it an excellent all-purpose format.
BMP (Bitmap)
BMP is an uncompressed format that stores image data without any compression. It produces very large files but maintains perfect quality. Best used for archival or when no quality loss is acceptable.
