What size an Instagram profile picture really is
The avatar on a profile is a small square file, and that square is the whole of what exists.

The avatar is stored as a small square
Instagram takes the photograph somebody uploads as their picture and publishes a square copy at modest dimensions. It has to load beside a name in a feed, in a comment thread and in a list of followers, so it is kept deliberately small.
The larger original stays with the person who uploaded it. What the site serves to a reader is the small square, and that square is the ceiling on anything you can save from a profile.
Instagram serves profile photos at modest pixel sizes. The circular crop you see on the site is layout, not extra resolution in the file. Saving the avatar gives you that published square, not a studio portrait.
Paste a public profile address. Private profiles and accounts that hide the avatar from logged-out viewers return no useful picture.
The round frame is drawn by the page
Avatars appear as circles everywhere on Instagram, and the file behind them is not circular. The rounding is styling applied by the page while it draws, in the same way a border or a shadow is.
The saved file is the square as published, with the corners the photographer took. Nothing has been cropped away by the download, and nothing needs restoring afterwards.
Enlarging the square does not create detail
A picture holds a fixed number of pixels. Stretching it to fill a bigger frame spreads those pixels over more space and invents nothing, so the result is soft edges and blocky skin rather than a clearer face.
Software that offers to enlarge a photograph is guessing at the pixels between the ones it has. The guesses can look tidy at a glance and they are not the detail from the original camera file. A small square is a small square, and the person who uploaded it holds the only sharp copy.
Profiles that hand back no picture
A private account limits what a signed-out reader receives, and on many profiles the avatar is part of what is withheld. The profile page loads with the name and a note about the account being private, and no image address is served with it.
An account that has never set a picture shows the grey placeholder Instagram draws for an empty slot. That placeholder is not a photograph, so there is nothing behind it to save.
Both cases produce an empty result, and the empty result is the accurate answer for a profile with no public picture attached.
What a profile address returns in the results
Paste the address of the profile itself, the one holding the account name after the site name. A post address points at a post and will not give you the avatar.
The list that comes back is short, because a profile page carries one picture rather than a ladder of encodings. Press Download file on it and the square is written to your device: the Downloads folder on a desktop, or device storage on a phone. The tab needs to stay open until that write has finished.
Free use for a file this small
An image of these dimensions is a few dozen kilobytes, so the 150 MB limit on a single free download is irrelevant here. Free use covers 3 downloads a day and that count returns to three at midnight UTC, and a saved picture spends one of them exactly as a video would. A Pro account drops the count, drops the ceiling and drops the advertising.
The photograph belongs to the person in it
An avatar is usually a picture of somebody, taken by somebody, and being able to see it on a public profile is not permission to publish it elsewhere. Reusing a person's face carries obligations that have nothing to do with file sizes, and Vidzilla is not connected to Instagram and grants no rights over anyone's picture.
Keep this tab open until the browser finishes writing the file for instagram profile picture downloader. A prepared file only waits a short time before it expires from the temporary store.
Free use on Vidzilla covers three downloads a day and files up to 150 MB on video tools unless a converter page states its own quota. Pro raises those limits and removes advertising where ads appear.
Questions about profile pictures
Can I get the full-resolution version of somebody's avatar?
No. Instagram publishes a small square and keeps nothing larger available to readers, so the square is the largest copy in existence outside the uploader's own device.
The picture I saved looks blurry when I open it full screen.
Your screen is far wider than the image, so the viewer is stretching it. Displayed at its own dimensions the file is sharp.
Why is my saved image square when the profile showed a circle?
The circle is styling drawn by the page around a square file. The download hands you the file, and the styling stays behind.
Nothing came back for a profile I can open in my browser.
A private account withholds the picture from a signed-out reader, and every page here is read signed out, so no image address is served.
Does an upscaling tool fix the resolution afterwards?
It invents pixels between the ones that exist. The output is larger and it is not the detail from the photograph the person uploaded.
Should I paste the profile address or one of the posts?
The profile address, which ends with the account name. A post address points at that post and returns the post's media instead.
