Supported formats
This tool accepts JPG, PNG, WebP, HEIC as input and gives you a 30KB image as output. Everything happens on your device in seconds — your file is never uploaded, so there is nothing for anyone to keep.
Generation loss: why the starting JPEG matters
JPEG compression is lossy, and the losses stack. Each time a JPG is opened and saved again, the encoder makes fresh approximations on top of the previous ones. After a few rounds — a chat app, an editor, a screenshot — faint blocks and colour smudges start to show, and they eat into a 30KB budget because the encoder treats them as detail.
So the best 30KB file comes from the best source: the photo straight from the camera, or the highest-quality copy you have. The tool re-encodes it only once, at the single quality setting that fits.
