Compress Image

Why exact targets beat “compression levels”

Most compressors offer low/medium/high settings — and leave you guessing whether the result passes your form. KBWise works backwards from the rule you’re trying to satisfy: you state the limit, the engine finds the best quality that fits under it. No retry loop, no guessing.

Every tool here shares the same engine: binary search on quality, controlled dimension stepping only when the target demands it, an honest verdict when a target isn’t reachable, and a before/after preview so you judge the quality yourself.

Quality vs dimensions — the two dials

Image size is controlled by two things: encoding quality (how aggressively detail is approximated) and pixel dimensions (how much image there is to encode). Lowering quality is nearly invisible until it suddenly isn’t; reducing dimensions is invisible as long as you stay above the size anything will display.

The engine therefore spends quality first — it’s the cheaper currency — and touches dimensions only when a target can’t be met otherwise. You’ll see the choice it made in the result panel every time: final quality verdict, final dimensions, no surprises. And because the output is freshly encoded, EXIF metadata (camera, settings, GPS) is stripped along the way.
