Where are my files processed?
Selected files are processed in your browser. Importing a URL uses the download service to retrieve the remote file.
What if processing fails?
Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
