# AI Agent reads HEIC and HEIF images

Your AI Agent now reads HEIC and HEIF images, the default photo format on iPhone. An end user who emails a photo straight from their camera roll no longer needs to convert it first.

## What's new

HEIC and HEIF join PNG, JPEG, and GIF as image formats the Agent reads on Email.

* **Converted on receipt**: each HEIC or HEIF image the Agent reads is converted to JPEG when it arrives. The JPEG is what the Agent reads and what human agents receive on handoff.
* **Large photos are scaled**: images wider or taller than 4096 pixels are scaled down during conversion. Images over 50 megapixels are not read.
* **Same rules as other images**: the inbox's attachment handling setting, the 3-image limit, sensitive-image detection, and your redaction rules apply unchanged. See [Images](/docs/other/images).
