Can you have a PDF larger than 25 MB signed digitally?
Updated
Short answer
Yes. Many signing tools limit documents to a few dozen megabytes; at DocuSign it is 50 MB. BuiltSign handles PDFs up to 1 GB per document on Business Plus and Enterprise, up to 250 MB on Business and up to 80 MB on Pro. So you don't have to split a large contract with drawings or attachments.
Why documents get so large
Construction drawings, scanned attachments, photos in a handover report and contracts of hundreds of pages quickly add up to tens or hundreds of megabytes. Splitting them means separate parts signed separately, and a harder story if there's a dispute later about what exactly was signed.
How to sign a large document in BuiltSign
- Upload the PDF, even if it's hundreds of megabytes.
- Place the signature fields. The signer gets a preview that loads quickly, also on a phone.
- Send. When it's done, there's one signed document with one audit certificate, with a hash of the whole document.
Which limit applies to which plan?
- Pro: up to 80 MB per document.
