Profile Picture Size for Slack, Zoom, Teams, Discord and WhatsApp: What Each App Actually Publishes

Most size guides give an exact pixel number for every app. For work apps, most of those numbers are invented: only one of the five apps below publishes pixel limits. Here is what each one actually states, checked against its own help pages, and the single upload that works everywhere.

The short answer

Checked 29 October 2026 against Slack's help center and API docs, Zoom's in app upload message and Microsoft's community answers.

Why one 1024 pixel square works everywhere

1. It sits at Slack's ceiling. Slack accepts up to 1024 x 1024, the strictest published limit of the five.
2. It stays under Zoom's 2 MB cap as a JPG at normal quality. A 1024 pixel headshot is usually a few hundred kilobytes.
3. It is sharp on high density screens. Avatars display small, but phones and laptops render them at two or three times the pixel density.
4. It survives the circle crop in Zoom, Teams, Discord and WhatsApp, and Slack's rounded square, if your face is centered with a little space above your head.

App by app

Slack

Slack's help center states the photo must be at least 512 x 512 pixels and no larger than 1024 x 1024. Its developer documentation for the users.setPhoto method gives the same bounds. If your Slack email matches a Gravatar account, Slack shows your Gravatar until you upload a photo of your own.

Zoom

Zoom's upload dialog asks for a JPG, JPEG, GIF or PNG file smaller than 2 MB, then lets you crop it. Zoom does not publish a pixel size. Profile photos are usually changed in the Zoom web portal under your profile, which is why many people cannot find the option in the desktop app.

Microsoft Teams

Microsoft does not publish a pixel size for Teams profile photos. Two practical points from Microsoft's own community answers: the photo is shown as a small circle, and an administrator can switch off photo changes through a mailbox policy, in which case no upload will work and you need IT to change it.

Discord

Discord's help center does not publish an avatar pixel size. The avatar is shown as a circle in chat and a larger circle on your profile card. A square 1024 pixel upload covers both.

WhatsApp

WhatsApp does not publish a pixel size for profile photos. The app shows the photo as a circle in chats and lets you view it full screen, so a square 1024 pixel image looks sharp in both places.

Framing for the circle crop

Preview the circle before you upload with our circle cropper, and export the square at the right size with the profile picture resizer.

Use the same photo in every work app

Colleagues see you in Slack, then on a Zoom or Teams call, then in an email. One consistent photo across all of them makes you easier to recognise and is the simplest thing a remote team can do to put faces to names. If your company uses a shared look on its team page, match it.

The bottom line

Export one square photo at 1024 x 1024 pixels, save it as a JPG under 2 MB, center your face with a little room above your head, and use it in Slack, Zoom, Teams, Discord and WhatsApp. Treat any guide that quotes an exact "official" pixel size for Teams, Discord or WhatsApp with caution: those apps do not publish one.
