Save or publish as part of your Flow.
Note: Pyn's virus scanner may delay your ability to preview, realign, or resize the image.
Banner Image Dimensions
For banner-style images at the top of your message:
1200 x 250px (ideal banner format)
Because we use 600px as a common and reliable standard for broad compatibility, your content area is designed to render cleanly across devices.
For height:
We recommend ~240px
Avoid going over 350px in most cases
Given we use retina screens, it’s worth upsizing the image for higher quality.
1200px wide and 500px tall is a great target to ensure crisp rendering without distortion.
Quick Sizing Summary
Use Case | Recommended Size |
Standard banner | 1200 x 250px |
Flexible height | ~240px (max 350px) |
Retina-optimized | 1200 x 500px |
💡 Tip: Keep text minimal inside images to ensure accessibility and readability across devices.
