How to Upload Files into Arena

Last updated: June 30, 2026

Arena supports file uploads to help you provide additional context when prompting models. Uploading a file allows models to reference or work directly with visual input during generation.

How To Use

You can upload a file to Arena in two ways:

  • Click the “+” icon in the chat input box and select a file from your device

  • Copy and paste a supported file directly into the chat input

Once uploaded, the file will appear in your prompt before you submit it.

Supported File Types

In Battle Mode, Arena supports the following file types:

  • PNG (.png)

  • JPEG (.jpg, .jpeg)

  • WebP (.webp)

  • PDF (.pdf)

In Agent Mode, Arena supports the following file types:

  • PNG (.png)

  • WebP (.webp)

  • JPEG (.jpg, .jpeg)

  • PDF (.pdf)

  • GIF (.gif)

  • Plain Text (.txt)

  • Markdown (.md)

  • CSV (.csv)

  • HTML (.html)

  • XML (.xml)

  • CSS (.css)

  • JavaScript (.js)

  • JSON (.json)

  • XML (.xml)

  • JavaScript (.js)

Arena Switching Behavior

If you upload an image while using Text Arena, Arena will automatically switch you to Image Arena. This is intentional and assumes you’re looking to use Image Edit capabilities rather than standard vision-based prompting.

If you want to return to vision-based prompting in Text Arena, simply exit Image Arena to switch back.

When to Use File Uploads

File uploads are especially useful when:

  • Editing or transforming images

  • Providing visual context for a prompt

  • Comparing how models interpret the same image

As file support expands, uploads will enable richer workflows across additional arenas.
