Slack Profile Photo Resizer

What matters

Slack Profile Photo dimensions at a glance

Slack profile photos display as rounded squares at various sizes — 36px in messages, larger in profiles and the team directory. 512×512 covers all contexts.

Profile photos help teammates identify each other quickly in busy channels. A clear headshot is more useful than a logo or illustration.

Low-res photos look unprofessional in a work context. Missing photos show a generic colored initial, making it harder to scan conversations.

Best practices

Use the crop intentionally

• Use a clear headshot for personal accounts.
• Ensure the image is well-lit and the face is recognizable at small sizes.
• Square crop centered on the face works best for the rounded square display.
