# Supported Files & Limits

> Review supported file types, input requirements, and processing limits.

## Supported file types

| Category | Supported formats                                             |
| -------- | ------------------------------------------------------------- |
| Images   | `.jpg`, `.png`, `.bmp`, `.webp`, `.tiff`, single-frame `.gif` |
| PDF      | `.pdf`                                                        |

<Note>
  Each request processes a single image and returns one result synchronously. For multi-page or multi-frame input (PDF, multi-frame GIF), only the first page or frame is processed. Only single-frame GIFs are supported.
</Note>

## Input requirements

| Requirement       | Limit                        |
| ----------------- | ---------------------------- |
| Maximum file size | 50 MB                        |
| Image width       | Between 20 and 10,000 pixels |
| Image height      | Between 20 and 10,000 pixels |

## How to send the input

The endpoint accepts input in one of two ways, selected by the `Content-Type` header:

| Content-Type               | Request body                                                            |
| -------------------------- | ----------------------------------------------------------------------- |
| `application/octet-stream` | Send the raw bytes of the file, not FormData or any other wrapper.      |
| `text/plain`               | The URL of a remote file, as plain text (http and https are supported). |

<Note>
  For URL input, the remote file must also stay within the 50 MB size limit and the 20-10,000 pixel dimension range.
