Compress a photo to an exact KB size

The tool searches encoder settings and, when needed, scale until the file meets the cap. The result screen states whether the target was reached; very noisy PNG screenshots can still struggle on tiny limits.

Portals change rules by year and post. This page implements the size logic described here — always read the live form instructions before you submit.

The search stops at or under the number you type. If the form says “maximum 100 KB”, entering 100 is correct; the result screen shows the final size.

The file never leaves your browser. Open the Network tab while you convert if you want to verify that.
