The tool lowers the quality step by step until the file fits, and only scales the image down when quality alone is not enough.
The real-world form requirement: an exact pixel size that also has to stay under a file size limit.

Resizing an Image to 300×300
300×300 is the size you need for small avatars, icons and thumbnail grids. At 300x300 the file is only a few kilobytes, which is why it is the default for comment avatars and listing thumbnails. Uploading a much larger photo and letting the platform scale it down usually costs sharpness, so it pays to resize to the exact size yourself.
Why Resize to 300×300?
Detail is lost quickly at this size - crop tightly to the subject before resizing rather than shrinking the whole scene. Keeping the aspect ratio fits your photo inside 300×300 without distortion; turning it off forces the exact dimensions, which is what some upload forms insist on.
Resizing to 300×300 Step by Step
Drop the image into the upload area, check that the width and height read 300×300, pick your output format and click resize. The result appears with its new dimensions and file size so you can verify it before downloading. Everything runs in your browser, so nothing is uploaded.
