How to use this tool
Select an image from your device and enter a short caption. The tool draws a white label with a dark outline near the lower-right corner and offers a PNG download. Keep an untouched source copy and inspect the exported image at full size to ensure the text does not hide important detail.
Check the result
Long captions are limited to the first 100 characters. The canvas is capped at 4096 pixels per side and inputs at 25 MB. A visible watermark can be cropped or removed; it is not a rights-management or ownership verification system.

Frequently asked questions
Can I save my result?
Run the tool, then use its download control. Text results can be saved as a file; image and audio tools show their available export links after generation. A disabled download means a new result is needed.
Are my inputs uploaded?
The tool processes your input in this browser tab. Opening the page downloads the site assets; your tool inputs are not sent to a processing server. Save your result before closing the tab.
How do I start again?
Use Restore example to reset the editable fields, then run the tool again. Changing input invalidates the previous export so that you can generate a fresh result.
