Batch converting PNG to JPEG is one of the fastest ways to reduce the total size of an image collection. Photographic PNGs can be 5-10x larger than their JPEG equivalents, so batch conversion provides massive savings.
With ImgTools, upload your PNG files, select JPEG as the output format, set your quality level (80-85% recommended), and process all files. The converter handles each image individually while applying consistent settings.
This is particularly useful when migrating a website, cleaning up a photo library, or preparing images for platforms that prefer JPEG format.
Remember that JPEG does not support transparency. Any transparent areas in your PNGs will be filled with white when converted.
