No — resizing happens in your browser and the file never leaves your device.
300×300 is the standard size for thumbnails and lightweight avatar images where a small file size matters.
A smaller target size like this also naturally produces a smaller file — helpful if the platform has a small avatar upload limit.
Need a different size? The image resizer accepts any custom width and height.
