By using this method, the resulting PAdES will have a manageable size and performance should improve. This is achieved through a change in the configuration, so you must ask Signicat to make this change if you intend to use this method. In such cases, Signicat recommends the use of detached signature, which is performed by not including the source document in the XAdES (resulting XML document attached to the PAdES). In cases where a PAdES package might exceed the limits outlined above, the risk of an error occurring during the packaging process (due to timeouts, memory starvation or similar issues) is higher the bigger the package is. The diagram above tells us that this restricts the original document to a maximum size of ≈ 5 MB. In general, it will never be possible to use a document which results in a signed document size that exceeds 10 MB. The largest possible document size will vary, depending on the signing method. Therefore try to keep your documents as small as possible. It will also increase the sensitivity when it comes to network connectivity. It will reduce response times and make the application seem slower.

Transferring these data amounts comes at a cost. In addition, if you are using Signicat’s PackagingService to create PAdES or LTV-SDO output, the size of the final result document will be even larger than that in terms of document sizes only (disregarding data transfer), a 5 MB original will result in a 10 – 15 MB PAdES result. As you can see, the total payload will exceed 10 MB when the original document is larger than 2.5 MB, or 20 MB when the original is 5 MB. This diagram illustrates the amount of data required to be passed back and forth between the end-user and Signicat during a signing process. The x-axis shows the original document size in KB, so 740 KB ≈ 0,7 MB, 2143 KB ≈ 2 MB, etc. Given that the original document is 1 MB, the following transmission sequence will take place: 1 MB + 1 MB + 1.33 MB + 1.77 MB + 1.77 MB = 6.87 MB.
BASE64 ENCODING SIZE INCREASE DOWNLOAD
The end-user is required to download the base64-encoded document, which is what will be signed.
BASE64 ENCODING SIZE INCREASE PDF
The end-user is required to download the original document, usually in a binary format so that it can be displayed in a PDF reader without conversion.Base64-encoding a document will increase the document size by about one third. Signicat prepares the original document for the signing process, encoding it in a format suitable for web data transmission.The original document is sent in binary form from your server to Signicat.

During a signing process, the following data transmissions will occur, with slight variations depending on the signing method: It is highly advisable to keep document sizes to a minimum at all times. Learn about our different signature services in our introduction to our electronic signature APIs. The information on this page applies to both our SOAP services as well as our REST Sign API. We need to make sure to revoke the URL if we no longer need the file. addEventListener ( 'change', ( e ) => ) querySelector ( 'input' ) // Listen for the change event so we can capture the fileįileInput.

Get a reference to the file input const fileInput = document. We use FileReader to convert the file object to a dataUR this is done by using the readAsDataURL method. In both examples we’ll use a file obtained from a file input field.

In this tutorial we’ll explore how to use JavaScript to generate a Base64 string and a DataURL from a file object. For example when we can only send string based data to the server. Converting JavaScript file objects or blobs to Base64 strings can be useful.
