Cut an image down to fill a shape
Cropping removes what falls outside the shape rather than padding around it. The cut is taken from the centre.

What happens when you drop a file in
The file stays put. Your browser opens it the same way an image viewer would. There is no transfer, which is why there is no upload bar to watch.
An encoder arrives once. The first job on this site pulls down a compiled build of FFmpeg, roughly 30 MB. It is kept afterwards, so every job after the first starts immediately.
Your own hardware does the job. The work happens in this tab, on your processor. A laptop from the last few years handles short clips in well under real time.
The result lands in Downloads. Assembled in memory and handed straight to your browser. Close the tab and every trace of it is gone.
Two operations people constantly confuse
Resizing keeps the entire picture and alters how large it is. Cropping keeps the scale and discards whatever lies outside the requested shape. Mixing the two up is how people end up with bars they never wanted.
For a profile photograph, a square thumbnail or any fixed slot, cropping is what is actually wanted. The image fills its frame and reads as intentional rather than accidental.
What it costs is the edges. On a centred subject that is nothing at all. On a composition where something important sits near the border, it can remove the reason the photograph was taken.
Centre, and why
Deciding which portion of an image to keep is a compositional call, and calls like that need to be seen as they are made. A page cannot offer a draggable preview without turning into an editor. The centre is correct far more often than not, and when it is not, that is precisely the moment an editor earns its place.
Common questions
Can I pick the region?
No, the crop is centred. That suits most images; off-centre subjects want an editor.
Does it resize too?
No. What remains is at its original scale — only the edges go.
Which ratio for an avatar?
Square, almost always. Most platforms cut a circle from a square.
Is it uploaded?
No, cropping happens in your browser.
