1 KB means 1,024 bytes here. The tool tests a bounded set of native quality settings and never pads a file to pretend an exact size. If your target is missed, download stays disabled.

Still images only, up to 10 MiB, 8,192 pixels per side and 16 million pixels. SVG, GIF, HEIC and animated images are refused before decoding. Source orientation is applied by the browser.

Keeps the whole image and its aspect ratio within the maximum dimensions. Never enlarges a smaller source.

Whole KB, 1–10,000. Required target. Dimensions remain fixed during quality search.

Output is bounded to 4,096 pixels per side and 8 million pixels. Transparency becomes white. JPEG and WebP may lose detail; PNG size is not controlled by quality. Browser encoders can differ.
