What fits in 50 KB
50 KB holds a small, clear photo, often around 1000 to 1500 px on its longer side. That is plenty for a portrait on a form or an ID card, and too little for a full-size photo from a phone.

Plain backgrounds compress better
A plain wall behind the face takes almost no bytes; leaves, patterns or a busy room take many. If a photo will not get under 50 KB in good quality, a photo with a calmer background will.
Quality first, then pixels
A JPG or WebP file gets smaller in two ways: a lower quality, which drops fine detail the eye hardly sees, or fewer pixels. The tool lowers the quality first, only as far as the photo still looks good, and then makes the photo smaller. Tick “Keep the dimensions” when the size in pixels must stay; then only the quality goes down.
When the photo itself is the problem
Compression makes a photo lighter, not better: it cannot fix a blurry, dark or badly framed picture. If the photo is for a CV, a profile or an application and you have no good one, a professional headshot made from a few selfies gives you one.
