For images, you can upload a file, add alt text, choose cropping, corners, border, shadow and possibly a click destination. Video, audio and post blocks use the public URL of the hosted content.
Best practices
- Use a sharp, lightweight image that you own the rights to.
- Add useful alt text when the field is offered.
- Paste the public URL of the piece, video or post, not a private management URL.
- Test on mobile, as the height of a player or a post can vary.
- Provide a fallback link when embedding is essential to your journey.
Processing of main images
Profile photos, covers and contact cards accept common raster images, including JPEG, PNG, GIF, WebP, AVIF and BMP. They are standardized to JPEG. The profile photo is cropped to a square at 150 × 150 pixels, the contact photo at 84 × 84 pixels, and the cover is resized up to 580 pixels wide. The generated file aims for a maximum size of about 1.5 MB. Sources exceeding 16 megapixels are rejected.
