Frequently asked
Will the signature hide the text behind it?
No. Signatures are saved with a transparent background, so the document text underneath stays visible.
Can I add text as well as a signature?
Yes — add text boxes, highlights, drawings and shapes, and rotate, reorder or delete pages before downloading.
Can someone else sign the document?
Yes. Place signature, name, ID and date fields, then send the secure link by WhatsApp or email. The signer needs no account and can sign from a phone. You get an email when it's signed.
How can I prove the document wasn't changed?
Every document signed by link gets a certificate page with a unique document ID, the original file's SHA-256 fingerprint, exact timestamps and the audit trail. Anyone can upload the file at fileopard.com/verify to confirm it matches the signed record.
Is this a certified digital signature?
It's an electronic signature with an audit trail, which is accepted for many everyday documents. It isn't a certificate-based (PKI / qualified) digital signature.
