Compress to Exact File Size
Switch to Target size (KB) mode when an upload form caps attachments at 200 KB or email providers reject large inline images. The compressor binary-searches JPEG or WebP quality until the output fits your budget — with a live before/after preview for single files and a CSV report for batches.
