Are my images uploaded?

No. Files are decoded, renamed, converted and packaged in your browser. LocalReach Tools does not send them to a server.

Which image formats are supported?

JPG, JPEG, PNG, WEBP and BMP files can be selected. Output can stay original or be encoded as PNG, JPG, JPEG, or WEBP when your browser supports it.

How are transparent images handled when converting to JPEG?

JPEG cannot contain transparency, so transparent pixels are composited over a white background before encoding.

What do I download for a batch?

A single processed image downloads directly. Two or more processed images are placed in a ZIP archive containing only the completed outputs.
