Common questions
Are my files uploaded?
No. This tool processes files in your browser. Files are not sent to ClarityKit or an external API. Reset the tool or close the tab to release the working files.
What should I do if processing fails?
Check the supported formats and limits above. Try a smaller, unencrypted file and keep the tab open until the result is ready.
