50 KB is below what quality alone can do to a JPG
The search walks the quality range downwards from 96% in ten steps, and for a photograph out of a phone every one of those steps still overshoots 50 KB. So the second half of the algorithm takes over: the image is redrawn 25% smaller on each side, a little over half the pixels, and the whole search runs again, up to six times. What comes back is typically a picture around a thousand pixels on its long edge, at a middling quality, looking entirely correct at the size it now is. The thing to watch for is a form asking for 50 KB and a minimum width in the same breath. That is a request no JPEG encoder can satisfy, and the honest move is to go back and check whether the width was really a minimum rather than a maximum.
Will my photo still be recognisable at 50 KB?
Yes, but it will be small rather than soft. Because quality alone cannot get a phone photograph to 50 KB, the tool falls back to reducing the pixels, so what you get is a genuinely smaller picture at a decent quality rather than a full-size one that has been destroyed. For a passport-style headshot on a form, that is exactly right. For anything that has to be looked at closely, 50 KB is the wrong budget and no tool will change that.
The form wants 50 KB and a minimum width. Now what?
This is the loop that catches people, and it usually has a solution. Crop tightly first: a headshot cropped to the face carries far fewer pixels than the same photo with a room around it, and it will meet a width minimum at a much smaller file size. Convert to JPEG if you are starting from a PNG. If it still will not fit, the form's two requirements may genuinely be incompatible and the photo needs retaking against a plain background, which compresses better than a busy one.
Does cropping help more than compressing?
Usually, and it is the least obvious lever on this page. File size follows pixel count, and cropping removes pixels without touching the ones you keep. A headshot cropped to the head can carry a quarter of the pixels of the same photo with a room behind it, which lets the quality search stop far earlier and leaves the face sharp. Compressing harder does the opposite: it keeps the room and degrades the face along with it. Crop first, then come back here.
More on where 50 KB comes from, and on what compressing JPG actually does.
Should the output stay JPG?
Yes, unless the file is going somewhere modern. JPEG is what every form, portal and ID system on earth accepts, and at 50 KB that compatibility is usually the entire reason the number exists in the first place. Auto would often reach 50 KB with less visible damage by encoding WebP instead, and where the far end takes WebP that is the better answer by a margin you can see. Where the far end is a government upload field, do not experiment: keep JPG and take the smaller picture.
A different budget
The same budget for PNG. With no format in mind, compress any image to 50 KB. With no limit in mind, compress JPG.
