Please let me know how many images can I upload in free Chat Copilot daily? It allows me only to upload 3 images, and then I get a message that I reach the limit

Microsoft has not published an official daily image-upload limit for free Copilot Chat in the provided documentation. The documented limits that are available are:

• Up to 20 files in a single Copilot conversation
• Each uploaded file can be up to 50 MB
• Supported image formats include PNG, JPEG, PJP, and JFIF

For the daily-limit message specifically, the available guidance indicates that Copilot can enforce a daily usage threshold for uploads, but the exact daily cap and reset timing are not officially documented. If the limit message continues even after 24 hours, the supported troubleshooting steps are:

1. Confirm the images are in a supported format: PNG, JPEG, PJP, or JFIF.
2. Confirm each file is under 50 MB.
3. Avoid repeated retries after the limit message appears.
4. Reuse the same conversation when possible instead of starting many new upload sessions.
5. Sign out and sign back in.
6. Clear the browser cache or try a different browser.
7. Make sure the correct account is signed in, especially if a subscription was recently changed.
8. If the issue persists, contact Microsoft Support.

If only 3 images upload before the limit appears, that behavior is not matched by any published official daily image count in the available material.
