What file formats does the Dokobit portal support for signed documents?
In the Dokobit portal, documents can either be signed and downloaded as PDFs or in the following container formats: ASiC, ADoc, BDoc, and EDoc.
What is a container format?
In the context of e-signatures, a container format can be considered a type of archive file (such as the ZIP format). These kinds of archives are used to group numerous files together and can contain various document formats.
In the ADoc container, you can upload files in the following formats: PDF, DOCX, XLSX, ODT, ODS, ODP, PPTX, PPSX, TIF, TIFF, JPG, JPEG, PNG, JFIF, ADOC. The ASiC container, on the other hand, has no limits and can contain many other formats as well.
What is the difference between ASiC, ADoc, BDoc, and EDoc?
ASiC → A standard, internationally recognized container format that must be accepted by all EU institutions which handle electronically signed documents (this rule also applies to the PDF format).
ADoc → A national container format widely used in Lithuania.
BDoc → A national container format widely used in Estonia.
EDoc → A national container format widely used in Latvia.
How do I decide if my document should be signed in a PDF or a container format?
There are various aspects to consider before choosing the format of a signed document. Since every situation is different, we have put together a handy list of pros and cons to help you make the right choice.
- Contents of a signed PDF document can be easily accessed and previewed.
- Signature annotations can be added to visually indicate that, at some point, a signature was added to the document.
- The PDF format is supported by every eID tool or signing method available in the Dokobit portal, making it an internationally-friendly option for collecting signatures.
- Documents that are signed in the PDF format are limited to 1 file per upload.
- The uploaded file itself must already be in a PDF format.
- PDF format documents can contain a maximum of 40 signatures.
Container documents (ASiC, ADoc, BDoc, EDoc)
- An unlimited number of documents can be uploaded in a single container file as long as they don't exceed the total file size limit (100 MB in the "Free" plan, 500 MB in every paid plan).
- Supported file formats include but are not limited to PDF, DOCX, XLSX, ODT, ODS, ODP, PPTX, PPSX, TIF, TIFF, JPG, JPEG, PNG, JFIF, and many others.
- Container documents don't have any particular limits for the number of added signatures; however, we don't recommend adding more than 100.
- Accessing the contents of a signed document requires a separate software or the use of our validation tool.
- Signature annotations are not supported for container formats.
- Container documents cannot be signed when using "ElectronicID" video-based identification or eID tools that create authentication-based signatures, that way limiting its use internationally.
Where can I pick the format for my signed document?
Once you have registered a Dokobit account and logged into the portal, you can pick the appropriate format in the first step of the document uploading process before it gets sent out for signing.
When a document has already been signed, is it possible to convert it into a different format?
When a document has already been signed, it cannot be converted into a different format. The required format must be picked during the document uploading process in the Dokobit portal.
