Compress an image to 180 KB
180 KB gives you a little headroom under a 200 KB cap, which is a smart target when a form is strict about staying below the limit. The tool below is set to 180 KB and finds the quality that hits it.

Headroom under a 200 KB cap
Aiming for 180 KB instead of exactly 200 leaves a margin, so a tiny size variation will not push you over the limit and get the upload rejected.
At 180 KB a properly sized photo or scan looks clean. If the original is oversized in pixels, resize it first so the budget is well spent.
How it reaches 180 KB
The tool steps JPG quality down and measures the result until it sits at or just under 180 KB. No repeated exporting and checking by hand.
Everything happens locally in your browser, so even a sensitive document image never uploads and stays on your device.
