Export WebP or AVIF for web delivery, JPEG for photos, or PNG when lossless output is needed.

Compression is the default task, so images stay at their current width and height unless you choose to resize them.
Review the size saved before downloading
Compare input and output sizes for each image, then collect the finished files in one ZIP download.
