What is a JPG size increaser?

A JPG size increaser raises the file size of a JPEG in kilobytes—searched as “increase jpeg size,” “jpg size increase,” “how to increase file size of jpeg,” and “image file size increaser.” People need it when a portal rejects photos that are too small in KB. This free local-first tool re-encodes the image and pads the JPEG so the download lands on 100KB or 200KB without changing the picture layout. It does not upscale megapixels.
