The tool requires a valid license key or active subscription to be used without export watermarks.

If you're using the tool without a license, it runs in Unlicensed mode - fully functional, but with watermarks on all exports. This mode is intended for evaluation and testing only. Public sharing of unlicensed outputs is only allowed with proper credit (e.g. tag @antl.ii or link to antlii.work).

To unlock full usage rights and remove watermarks, please purchase a license or subscribe:

All-tools subscription (commercial use included):

By using any tool on https://antlii.work, you agree to the License Agreement. The agreement explains usage rights for Personal and Commercial licenses, subscription terms, and examples of what’s allowed.

The tool accepts raster images in JPG/PNG/WebP formats as source material, and it also support transparency. You can upload images of any size, as the program will scale it down, the threshold value for the resize can be set in the program settings.

• Image Size: Image size directly affects performance and depending on the type of video card you have and the browser you are using, you may receive a warning that the image size is too large:
  Warning: The requested width/height exceeds hardware limits. Adjusting dimensions to [width], [height].
  For this reason, in the program settings you can find the image size limitation parameter, which will reduce the image to the defined threshold value upon uploading the image.
  
  

• Browser Performance: Rendering speed can vary widely depending on your hardware and browser. If you notice significant slowdowns, try switching to a different browser - Chrome and Firefox tend to offer the best performance.


• Video Export: During export to video, the process may stop due to insufficient memory, especially with high resolution or long videos. If this happens, try reducing the resolution or length of the video. For large or high-resolution videos, consider exporting as a PNG sequence and later converting it to a video using the FFmpeg library.


• MP4 Lag: When exporting to MP4 format, a library-related lag can lead to performance drops, causing the program to slow down noticeably after capturing and exporting the animation. Refreshing the page resolves this issue.
  


• Mobile Support: The tool isn’t optimized for mobile devices. You’ll need at least an 800×600 display to run it reliably.

Please let me know if you're running into any issues or discover a bug while using the program.
