There are plenty of photo-improvement tools on the market, but few are as specialised or effective as this one. It sounds like hokum, but UnJpeg is surprisingly good at restoring images saved in the lossy JPEG format at less than 100 per cent quality – back to as much as 98 per cent of their original state. A low-level data analysis process reveals damaged image regions, which are then recovered using interpolation and heuristic image-building technology, all of which can be fine-tuned. JPEG artefacts are removed and you can even, uniquely to the best of our knowledge, remove median noise in heavily damaged images using the included tool. It isn’t cheap, but it does ‘just work’, and for the hard-pressed web designer it represents a useful addition to the armoury against over-compressed images.
