When batch compression saves real time
Compressing images one at a time is fine for a single photo and tedious for thirty. Product catalogues, event galleries, property listings, portfolio pages, and blog archives all tend to arrive as a folder of large files straight off a camera or phone, and every one of them needs the same treatment.
The bulk tool applies one set of settings across every file you upload and returns the results as a single ZIP archive. That turns a repetitive half-hour of uploading, waiting, and downloading into one pass.
