Worth knowing.

Compression results depend on image content, output format and dimensions. This tool checks output bytes instead of promising a fixed percentage saving.

Your questions, answered.

Does Bulk Image Compressor upload my files?

No. Files are read and processed in your browser. Codecs and optional model files may download to the device; your source images are not sent with those requests.
