PDF Signer (E-Sign)
Draw, type, or upload your signature, position it with exact coordinates, and export a signed PDF document.
Signatures (drawn, typed, or uploaded) are rendered and embedded as cryptographic bitmap stamp appearances in local memory with zero server uploads.
Signing contracts, NDAs, lease agreements, and permission slips often requires printing, signing by hand, and scanning. This in-browser electronic signing utility allows you to draw a signature with your mouse or touchscreen, type a cursive signature representation, or upload an image stamp, and place it directly onto your PDF pages without cloud uploads.

- ✓ Bypass file upload size caps and process your pdf signer (e-sign) tasks directly in browser RAM.
- ✓ Works instantly in your browser without requiring desktop software installation or admin rights.
- ✓ Zero data leakage guarantee—files are processed locally and never stored on remote servers.

Important Operational Notes & Realistic Limitations
- This tool creates an electronic signature representation; it does NOT produce certificate-based cryptographic digital signatures with PKI encryption.
- Certain high-compliance government filings, patent registrations, or notarized legal documents explicitly require cryptographic digital certificates and may not accept basic electronic image stamps.
- Existing interactive digital signature form fields (AcroForm signature widgets) are not digitally validated or converted into encrypted signature blocks.

Frequently Asked Questions
Is an electronic signature added with this tool legally binding?
In many jurisdictions (including under the US ESIGN Act and EU eIDAS regulations for standard electronic signatures), electronic signatures on commercial contracts are widely accepted by mutual consent. However, certain legal instruments (such as wills, deeds, and court filings) may require specialized cryptographic or notarized signatures. Verify requirements for your specific use case.
Does this tool support cryptographic digital certificates (X.509)?
No. This tool places an electronic image stamp onto the PDF. It does not provide PKI certificate signing, cryptographic hashing, or timestamp authority verification.
Can I place my signature on multiple pages of the same PDF?
Yes. You can navigate between pages, place a signature stamp on each required page, and drag each stamp to its specific line before exporting.
Can someone erase my signature after I download the PDF?
The signature is embedded into the PDF content stream as an image element. While basic PDF readers cannot undo it, someone with advanced PDF vector editing software could theoretically alter page elements. If permanent flattening is required, consider using PDF to JPG or our PDF Redaction tool to rasterize pages.
Can I draw my signature on a phone screen or upload a signature image?
Yes. You can draw with your finger or mouse, type your name using elegant script styles, or upload a transparent PNG signature.
Does signing a document upload my signature to your servers?
Never. Your signature and document are merged entirely inside your browser sandbox and never leave your device.
