The Slack profile picture size Slack asks for is a minimum of 512 × 512 pixels and no larger than 1024 × 1024 pixels. This guide covers that range, where your photo appears in a workspace and how to choose one colleagues will recognise at a glance.

Slack Profile Picture Size Range
- Minimum: 512 × 512 pixels.
- Maximum: 1024 × 1024 pixels.
- Shape: use a square image so Slack doesn't crop your face.
- Framing: keep your head and shoulders in the centre of the square.
The size range is from Slack's Help Center article on uploading a profile photo, checked when this page was last updated. Slack's article doesn't list file types, so use a standard JPG or PNG.
Where Your Slack Photo Shows Up
Your photo appears next to every message, in mentions, in the member directory and in huddles. In busy channels it is the fastest way for colleagues to see who posted.
In large or remote companies, people often meet in Slack first. A clear, friendly photo helps new colleagues recognise you later on video calls or in the office.
Choosing a Photo for Your Workspace
Slack shows profile photos as small rounded squares, so frame your head and shoulders and keep the background simple. Smart-casual clothing fits most company cultures.
If your company shares headshots across tools, such as Google Workspace, Zoom and the intranet, using the same photo everywhere keeps things consistent.
The generator makes square headshots you can resize into Slack's 512 to 1024 pixel range.
Preparing a Photo for Slack
Phone photos are usually much larger than 1024 × 1024 pixels, so crop your headshot to a square and resize it into Slack's range before uploading. Keeping a copy at about 1024 pixels gives the sharpest result on high-resolution screens.
Check the result in a channel and in the member directory, where the photo is shown at different sizes.
