How Can I Grayscale AVI Files?
That's an easy task for this online file grayscale tool: first, you need to
click on the "Select File..." button to select the AVI file want to grayscale, then click on
the "Upload File" button to begin to upload the file. This service doesn't
show the upload progress, however the upload speed depends on
your Internet bandwidth. Do not close this window while the file is being
uploaded and processed by our web service.
When the file has been fully uploaded, our service will grayscale the AVI file (it can
take some time), and once finished you will see a "Download File" link.
Keep in mind that after a few hours, all the uploaded and grayscaled files are automatically deleted. You should not share the download link,
it will not work for other Internet users.
