Quality is lowered only as far as the floor allows. If that still isn't enough, the image is scaled down in small steps instead — downscaling looks far better than heavy compression artifacts. EXIF metadata (location, camera, serial numbers) is always removed for your privacy; colour accuracy is kept.

Unlike quality-slider compressors, this tool works backwards from the file size you need. It binary-searches JPEG quality, and only scales the image down if the target can't be reached by compression alone — downscaling looks far better than heavy artifacts.

How it works

Set the exact target

Type the size your form demands — 20 KB, 50 KB, 1 MB — or pick a preset. The result always lands just under it.

Drop & resize

JPEG, PNG, WebP, GIF, BMP — one file or a whole batch. The engine finds the highest quality that fits your limit.

Nothing is uploaded

Every pixel is processed inside your browser. Your ID photos and signatures never leave your device.

Private by design

Nothing is uploaded — the compression runs inside your own browser using its built-in image engine. That means no size limits, no waiting for uploads, and no copies of your ID photos or signatures on anyone's server. EXIF metadata such as GPS location is removed from the output automatically, while colour profiles are preserved.
