Profile picture sizes: exact pixels and safe crop zones

When a profile picture looks blurry on LinkedIn or has the edges of a company logo chopped off on Instagram, the problem is almost never your camera. It happens for two mechanical reasons: either you uploaded a rectangular photo and let the platform’s automated server script squash and re-⁠compress it, or you placed important details in the outer corners of the square where the circular avatar mask trims them away.

Profile picture pixel dimensions across major platforms

Every platform below displays avatars inside a 1:1 square that gets masked into a circle (or a softly rounded square on Slack and GitHub):

Notice the pattern: one clean 800 × 800 px (or 1080 × 1080 px) square file under 1 MB satisfies every single platform on this list.

The circular crop rule: why 21.5% of your square disappears

Even though every upload form asks for a square image, almost every app displays that square inside a circle (border-radius: 50%). By basic geometry, a circle inscribed inside a square covers about 78.5% of the square’s area. The remaining 21.5% in the four corners is invisible.

For a portrait headshot, leave comfortable breathing room above your hair and outside both shoulders so your face occupies roughly the middle 60% to 70% of the square. For a wordmark or square company logo, shrink the mark so its widest corners stay inside a circle measuring 75% to 80% of the canvas width.

How to crop and resize a profile picture in two steps

Instead of uploading a 12-⁠megapixel phone portrait (complete with home GPS coordinates) to a random cloud “avatar maker”, prepare the file locally inside your browser:

1. Open the image cropper, choose your portrait or logo, select the 1:1 square ratio, and position the frame so your face or mark sits comfortably away from all four corners, then click Save crop.
2. Open the image resizer, select the cropped square, type 800 (or 1080) into the width field with aspect ratio locked, and choose JPEG for a headshot or PNG for a graphic logo.
3. Click Download to save your finished 800 by 800 pixel avatar with all EXIF and GPS metadata automatically stripped.

Because our image cropper and image resizer step large reductions down progressively on a local HTML canvas, fine details like eyelashes, glasses frames and shirt collars stay crisp instead of turning jagged.

Privacy note: what your raw portrait file carries before you resize it

When you upload an unedited portrait straight from your phone to a company directory, forum or intranet that does not strip metadata, the uploaded file often retains:

• Exact GPS coordinates and altitude of the bedroom, home office or garden where you took the selfie.
• Full uncropped preview thumbnails stored inside the EXIF IFD1 segment if you used an editor that forgot to rebuild the thumbnail header.
• Device model and timestamp showing which phone you carry and when the photo was taken.

Running your portrait through the image resizer or the lossless photo metadata remover before uploading ensures the public file contains only the square avatar pixels you meant to publish.
