Supported Image Formats
PNG (Portable Network Graphics)
Best for images requiring transparency (like logos or icons) and lossless quality. Creates larger file sizes than JPEG.
JPEG / JPG
The standard format for photographs. It uses lossy compression to keep file sizes very small, but does not support transparency.
WebP
A modern format by Google that provides superior lossless and lossy compression. Often 30% smaller than JPEGs with identical quality.
BMP (Bitmap)
An uncompressed raster format. Rarely used on the web due to massive file sizes, but sometimes required for legacy software.
