eSign PDF Online — Legally Sign PDFs Without Printing

Why Print-Sign-Scan Is Worth Eliminating

The print-sign-scan workflow introduces a chain of quality losses: the PDF is rasterised when printed, then re-rasterised during scanning, and the resulting file is larger, blurrier, and no longer text-searchable. A contract that has passed through this cycle twice is difficult to read and impossible to search.

Electronic signatures solve this completely. The original PDF bytes are preserved, and the signature is embedded as a clean overlay directly on the existing content. The final file is the same quality as the original, often smaller than a scanned equivalent, and fully text-searchable.

Electronic Signature vs Digital Signature

These terms are commonly confused. They describe meaningfully different things:

For everyday use — employment contracts, NDAs, service agreements, rental applications, consent forms — a simple electronic signature (drawn or typed) is legally sufficient in most jurisdictions under the US ESIGN Act (2000) and EU eIDAS Regulation (2016).

Legal Validity by Jurisdiction

Electronic signature laws exist in over 60 countries. The major frameworks:

• United States (ESIGN Act) — electronic signatures are legally valid for most commercial and consumer transactions. Excluded: wills, trusts, court orders, and adoption papers (must be handwritten).
• European Union (eIDAS) — three signature levels (Simple, Advanced, Qualified). Simple eSignatures are valid for most contracts. Qualified Electronic Signatures (requiring a QTSP-issued certificate) have the same legal effect as handwritten signatures throughout the EU.
• United Kingdom (Electronic Communications Act 2000) — electronic signatures are admissible in evidence and legally valid. Post-Brexit, UK follows its own framework aligned with but separate from eIDAS.
• India (IT Act 2000) — electronic signatures are valid. Certain documents (powers of attorney, negotiable instruments, property transfers) require physical signatures or a Digital Signature Certificate (DSC).

How to Sign a PDF Online

1. Open the eSign PDF tool.
2. Drop your PDF onto the upload area or click to select. The document loads locally using PDF.js — no upload occurs.
3. Choose a signature method: Draw (sign with mouse or touch), Type (enter your name in a cursive font), or Image (upload a PNG of your existing signature).
4. Create your signature in the signature pad.
5. Click Place Signature on PDF, then click the spot on the page where you want it.
6. Drag to reposition; use the corner handle to resize. Repeat for additional signatures or initials fields.
7. Click Download Signed PDF to save the completed document.

Signature Mode Comparison

Creating a Reusable Signature Image

For consistent, professional-looking signatures across many documents, prepare a signature image once:

1. Sign on plain white paper with a dark ballpoint pen. Avoid felt tips (ink spreads).
2. Photograph or scan the signature. Scanning at 300+ DPI produces cleaner results than a phone photo.
3. Crop tightly around the signature in any image editor.
4. Export as PNG. If your editor supports it, use a transparent background — a transparent PNG looks clean on any PDF background color.
5. Save the file somewhere accessible. Use the Image upload mode every time you need to sign.

A high-quality signature image takes 10 minutes to prepare once and eliminates the need to draw in a signature pad on every document thereafter.

Signing Multiple Fields and Pages

Many legal documents have multiple signature fields — a signature at the end plus initials on each page, or co-signer lines. After placing the first signature, click Place Signature on PDF again and click the next field location. Each placement is independent. You can create a separate shorter signature for initials by typing your initials in the Type mode and placing that on each page, then drawing your full signature on the final page.

Combining with PDF Form Filling

If the document has form fields that need to be completed before signing (a job application, a contract with variables, or an insurance form), use the PDF Editor first to fill in all fields, then use the eSign PDF tool to place your signature. Both tools work entirely in the browser with no uploads, so you can complete the full workflow without leaving the site or sending your document to any server.

PDF Document Signing Workflows

Signing a contract sent by email

Download the PDF attachment. Open the eSign PDF tool. Drop the PDF, add your signature, and download the signed version. Attach the signed PDF to your reply. The entire workflow takes under two minutes and produces a cleaner document than print-sign-scan.

Requesting a signature from someone else

This tool is for self-signing. For multi-party signing workflows where you need to request a signature from another person and track completion, use a service like DocuSign, Adobe Sign, or HelloSign, which provide signature request, notification, and audit trail features.

Archiving signed documents

Once signed, save the document in a dedicated folder using a consistent naming convention: YYYY-MM-DD_document-name_signed.pdf. The date prefix ensures documents sort chronologically. For important contracts, keep both the original unsigned version and the signed version.

Privacy: No Server Uploads

The eSign PDF tool runs entirely in the browser using the File API and pdf-lib. No part of your PDF or signature is transmitted to any server. Once you close the tab, the data is gone. This makes it safe for confidential documents: legal agreements, medical forms, financial contracts, and employment documents.
