PDF signing guide
How to Sign a PDF Online for Free
You do not need to print, scan, email, or upload a document to add a visible signature to a PDF. Valo Sign runs in your browser and keeps the working file on your device.
Sign your PDF in three steps
- Choose the PDF
Open Valo Sign and select the PDF from your device. The app checks and reads it locally; it is not sent to Valo Systems.
- Fill in and sign
Complete supported form fields or place text, dates, checkmarks, initials, and a drawn, typed, or uploaded signature where they belong.
- Check and download
Check every page and download a new PDF. The completed file has no Valo Sign watermark or branding.
Before you sign
- Confirm that the recipient accepts a visible electronic signature and does not require a certified or advanced electronic signature.
- Keep the original PDF until the completed copy has been accepted.
- Review names, dates, amounts, tick boxes, and every signature block before downloading.
- If the PDF already contains a cryptographic digital signature, editing it will normally invalidate that existing signature.
What stays private
The document, entered form values, and placed additions stay in the active browser session. Valo Sign does not create an account, save a cloud draft, or retain a document copy after you reload or close the tab. A signature or initials you save for reuse remains only in this browser until you remove it.
This boundary cannot protect against a compromised device, browser extensions, operating-system crash records, or software installed by the user. Use a device you trust for sensitive documents.
