Compress png to 100kb online free — Free & Private

Upload a PNG photo and compress toward 100 KB. The cap is fixed in the tool so you can meet limits on recruitment sites and ID-card workflows that ask for photos under 100 KB. You see the final file size in the workspace before downloading. The workflow targets 100 KB for PNG output — a limit often seen on recruitment sites and ID-card workflows that ask for photos under 100 KB.

You will see the final kilobyte reading before download. If the image cannot reach 100 KB without heavy artifacts, resize to fewer pixels first or choose the next larger KB preset in the same format.

Compression runs locally on rankify.in. Pair with a resize tool when a site lists both maximum pixels and 100 KB.

How It Works

Upload a PNG file (or a compatible image the tool accepts). The target is locked at 100 KB. Compression runs locally and the workspace shows the final kilobyte size before download. If the photo is too detailed to reach 100 KB without heavy artifacts, try resizing to fewer pixels first or pick a slightly higher KB preset.
