eSignAnyWhere (eSAW) manages documents in PDF format: the procedure also allows for files to be uploaded in other formats (e.g. files generated with the Microsoft Office suite), which are then automatically converted into PDF format when uploaded.
Each document (PDF) contained within an envelope can have a maximum weight of 10 MB.
The service does not allow documents upon which one or more CAdES signatures have already been affixed (e.g. files with a P7M extension), to be uploaded and managed.
