400 x 400 pixels is a 1:1 square and the size commonly recommended for profile pictures. X (Twitter) recommends 400 x 400 for the profile photo, and many other sites accept a square of this size for an avatar. A profile picture is shown small, next to every post and comment, but it is also opened full size when someone taps it, so 400 pixels gives enough sharpness for that without being needlessly large.
Open the photo you want to use, or several to compare. The size boxes already read 400 x 400 and the preview shows the square you will get. Download saves a picture exactly 400 pixels on each side, named after the original with -400x400 added: me.jpg becomes me-400x400.jpg.
A profile photo is almost always taller or wider than a square, and many sites also show it inside a circle, which hides the corners. Keep that in mind when you choose a mode and place the crop.
Crop to fill is the default and the right choice for a face. The photo is scaled to cover the whole square and the extra is trimmed. The preview shows the full photo with the kept square lit and the rest dimmed: drag the lit square, or tap where it should go, until your face sits in the middle with a little room around it. Leave space above the head and keep the chin clear of the bottom edge, since a circular frame cuts the corners away. If you prepare several pictures, each keeps its own crop; pick its thumbnail to set it.
Fit inside keeps the whole picture and fills the empty bands with white, black, any colour from the picker, or transparent. It suits a logo or a brand mark used as an avatar, where cutting a letter off would look wrong. A JPG given a transparent background is saved as a PNG, because JPG cannot store transparency.
Stretch forces the photo to 400 x 400 without cutting anything. Faces are the easiest thing to notice when they are squashed, so it is best left for pictures that are already square.
To make avatars for a whole team, add every photo with the + tile after the thumbnails; each gets the same size and its own crop. With two or more, Download as gives one ZIP, separate images (the share sheet on a phone) or, in Chrome and Edge on a computer, a folder you pick where the files are written directly.
Each file keeps its format by default: JPG stays JPG, PNG stays PNG, WebP stays WebP. The menu beside Download converts them to JPG, PNG or WebP, and the Quality slider sets JPG and WebP quality. A phone photo shrunk to 400 pixels loses most of its pixels, so the resizing uses a Lanczos filter, which keeps eyes, hair and edges crisp rather than mushy. Phone photos are turned upright from their EXIF orientation before anything is cropped. A file that is already 400 x 400 in the format you chose is handed back untouched.
Need another size? Type it into the boxes or open a page made for it: 512x512 for icons, 600x600 for thumbnails, 1080x1080 for a square post, or 1500x500 for an X header. For one picture with every option, use Resize Image.
X (Twitter) recommends a 400 x 400 pixel square. The file this page saves is already that size and shape, so what you framed in the preview is what people see, minus the corners the round frame hides.
Use Crop to fill and drag the lit square until your face is in the middle with space around it. The corners of the square are hidden by a circular frame, so nothing important should sit near them.
Yes, it is enlarged to fill the square. Enlarging cannot add detail, so the result may look slightly soft; a larger original gives a sharper avatar.
No. The cropping and resizing happen in your browser, on your own device, and nothing is sent to a server.
