Uploading a PDF for signing
3 min read
Updated Apr 14, 2026
The source PDF is the foundation for everything that follows. Clean uploads reduce signing friction, improve mobile readability, and make final artifact generation more reliable.
Before you begin
A finished PDF under 20 MB
A clear document title
Confidence that the PDF reflects the version you intend to send
Validate the source file
Signelio currently expects PDF as the canonical signable input.
If the file came from another format, confirm the conversion preserved page order and readability.
Upload from the wizard
Use the upload step to attach the source PDF and confirm file details.
Once the file is attached, you can move into recipients, routing, and review.
Treat the PDF as the record
The signed PDF later generated for completion is derived from this source asset.
That means early PDF quality affects the clarity of the final output.
Pro Tips
Avoid image-heavy PDFs unless the workflow truly needs them.
Keep filenames descriptive before upload so local records stay easy to trace.
Test a sample package if your source PDFs come from a new document generator.
