File Size Limits

- For GIFs, we recommend keeping the size under 100 kB for best performance.
Recommended Image Dimensions
- Images (excluding GIFs) are automatically resized by Swim POS on send.
- For best display, maintain a 1:1 aspect ratio (e.g. 300 × 300 pixels).
Note: Staying within the recommended file sizes and dimensions helps ensure images display clearly and are reliably delivered to all recipients.
