What size you actually get
X keeps every avatar in several sizes and serves a small one in the timeline. The largest is the file exactly as it was uploaded, with no reduction applied, and that is what this tool asks for.
Measured on a real account, the difference is large. The timeline version came back at 7 KB and the medium one at 21 KB, while the untouched upload was 25 KB, roughly three and a half times the timeline version. Each candidate is checked against the server before you are offered a link.
| Version | File size |
|---|---|
| Shown in the timeline | 7 KB |
| Medium size | 21 KB |
| Original upload (what you get here) | 25 KB |
An honest ceiling. X caps avatars at 400 by 400 pixels during upload, so "original" here means the uncompressed 400-pixel file rather than something dramatically larger. Any tool promising a 1000-pixel X avatar is either upscaling it afterwards or describing a different platform.
Handles change, accounts do not
An X handle can be changed at any time, and the old one becomes available for someone else to claim. That has two consequences. A lookup on an old handle may return nothing, or it may return a completely different person who has since taken the name.
Opening the profile and copying the handle from the address bar is the reliable fix. If you are checking whether an account is genuine, compare the numeric account ID rather than the handle, since only the ID is permanent.
Protected accounts
Avatars on protected accounts stay publicly visible. Protection covers posts, not the profile picture, which is why a locked account still shows a picture to people who do not follow it. When a lookup on a protected account fails, a stale handle is the usual cause rather than the privacy setting.
Header images are separate
The wide banner behind the top of a profile is a different image with a different shape, stored separately. This tool handles the round avatar only.
Saving the file on your device
iPhone. Download opens the image in Safari. Long press it and choose Add to Photos.
Android. The file goes to your Downloads folder and appears in your gallery.
Desktop. Right click Download and choose Save link as to rename it first.
When a lookup fails
The handle changed or the account was renamed. Copy the current one from the address bar.
The account is suspended or deleted. Nothing public remains.
The account never set a picture. X shows a generated grey placeholder, which is drawn rather than stored.
Using the picture afterwards
Profile photographs are usually copyrighted by whoever took them. Saving one for personal reference is ordinary use. Adopting someone else's avatar as your own can mislead people and breaches X's rules on impersonation, which are enforced against accounts rather than individual images.
