Issue Cryptographically Signed Documents
Static PNG signatures can be copied by anyone. In the DocuVerified Workspace, every document pairs authorized signatures with an unalterable QR code and SHA-256 fingerprint.
Why Traditional Image Signatures Need Verification
Pasting a static PNG signature into a PDF offers basic visual assent, but provides zero cryptographic proof against tampering or unauthorized reuse.
Vulnerable to Copy-Paste Forgery
Anyone who receives your PDF can easily screenshot your signature PNG and paste it onto unauthorized invoices, letters, or agreements.
No Proof of Post-Signing Edits
If an employee alters their salary figure or bank details after an offer letter is signed, an image signature cannot reveal that modifications occurred.
DocuVerified Cryptographic Ledger
In DocuVerified, signatures are bound to an unalterable SHA-256 document fingerprint and instant phone-scannable QR code verification.

Frequently Asked Questions
Everything you need to know about digital signatures, file formats, and legal validity.
Is a digital signature created here legally valid?
Under international electronic transaction frameworks (such as the US ESIGN Act, EU eIDAS regulation for basic electronic signatures, and regional commercial standards), electronic signatures applied to contracts, employment letters, and invoices carry legal validity when demonstrating intention to sign. For high-stakes statutory agreements, DocuVerified pairs signatures with cryptographic SHA-256 fingerprints and audit trails.
How does the auto-trimming / transparent crop feature work?
When you download your signature, our in-browser engine scans the canvas to detect the exact boundaries of your ink strokes, trimming away all unnecessary empty transparent pixels. This ensures your signature inserts cleanly into Word documents, Google Docs, or PDF files without misaligning surrounding text.
What is the difference between drawing and typing a signature?
Draw mode lets you hand-draw your natural signature using a mouse, stylus, or touchscreen with smooth Bezier curve velocity simulation. Type mode allows you to input your name and select from 13 authentic calligraphy and cursive typography fonts with optional signatory designation and company sublines.
Are my signature strokes or personal details stored on any server?
No. The tool runs 100% locally in your web browser using HTML5 Canvas and local JavaScript execution. Your signature data is never transmitted, stored, or processed on our backend servers.
