Frequently Asked Questions
PNG and WebP formats support transparent backgrounds, while JPEG and BMP formats do not. If the original image has a transparent background, it will become white when converted to JPEG.
PNG to PNG is lossless, other conversions may have slight quality loss. You can control the loss by adjusting quality parameters.
WebP is a modern format developed by Google with 25-35% better compression than JPEG and better quality, but relatively poor compatibility.
Currently supports single image conversion. For batch processing, please upload and convert images one by one.
