Free In-Browser PDF Form Filling & Electronic Signing

Whether you are finalizing an employment contract, approving a freelance work agreement, filling out a tenant lease application, or signing a school permission slip, adding a signature to a PDF should not require purchasing bloated desktop software, installing third-party mobile apps, or creating an account on a paid subscription platform.

FivoTools Fill & Sign PDF provides an intuitive, zero-install workspace directly inside your modern web browser. You can load any PDF file, navigate between pages, draw a custom signature, type a signature script, place text blocks and date stamps, fill out interactive AcroForm fields, and lock the document through permanent form flattening before exporting a fresh, signed copy.

100% Client-Side Processing: Your Documents Never Leave Your Device

Legal agreements, business NDAs, employment records, and real estate contracts contain sensitive financial numbers, addresses, and personal identification data. Most online PDF editors upload your confidential files to remote cloud servers to perform rendering and stamping operations, creating significant data privacy risks.

FivoTools operates under a strict zero-cloud-upload privacy contract:

Your PDF document is loaded directly into your browser's private memory sandbox via the HTML5 File API.
Your drawn signatures, typed text, and checkmarks are processed locally using standard Web Canvas and vector PDF libraries.
No PDF bytes, personal contact details, or signature images are ever transmitted over the network or stored in any remote database.
Once you close or refresh your browser tab, all in-memory document data is wiped clean immediately.

Electronic Signatures vs. Cryptographic Digital Signatures

Important Legal & Technical Disclosure

FivoTools provides Electronic Signatures (e-signatures)-visual signature overlays, typed acknowledgments, and form fillings recognized for everyday business under statutes like the US ESIGN Act and EU eIDAS regulation for basic electronic agreements.

This tool does not produce public-key cryptographic digital signatures (such as X.509 PKI certificate-backed signatures, Qualified Electronic Signatures (QES), or hardware token timestamps). If your transaction legally mandates an authenticated cryptographic certificate issued by a government-licensed Trust Service Provider (common in high-stakes court filings, government tenders, or specific European notary acts), you will need a dedicated PKI certificate signing solution.

Three Ways to Create Your Signature

1. Freehand Drawing

Use your finger on a mobile touchscreen, a digital stylus on an iPad or tablet, or your mouse/trackpad on a laptop to draw a natural, fluid signature. Choose between classic document ink tones including dark charcoal, deep navy blue, or royal blue.

2. Script Font Typing

Don't have a touchscreen or stylus handy? Type your full legal name to render a professional handwriting script stamp. It formats cleanly with transparent backgrounds for seamless placement over contract signature lines.

3. Transparent Image Upload

If you already have a scanned image or photograph of your physical signature, upload your PNG or JPEG file. The editor embeds your real signature directly onto the exact page coordinates you specify.

Interactive Form Filling & Document Flattening

PDF files fall into two primary categories: standard flat documents (like invoices or scans) and interactive AcroForm documents containing fillable text boxes and checkboxes.

FivoTools handles both scenarios effortlessly:

Standard PDFs: Click "Add Text", "Date", or "Checkmark" to place movable text stamps anywhere on the page. Drag them to align precisely over signature lines or dates.
Interactive AcroForm PDFs: If the document contains native PDF form fields, our inspection engine automatically detects them and surfaces an interactive fields panel where you can type responses directly.
Document Flattening: By enabling our default "Flatten document on export" setting, all interactive form fields and stamp overlays are permanently merged into the page's underlying vector and raster layers. This prevents downstream recipients or viewers from modifying or tampering with your filled entries.

Frequently Asked Questions

Are electronically signed PDFs legally binding?

In most jurisdictions-including the United States (under the ESIGN Act and UETA) and the European Union (under eIDAS for standard electronic signatures)-electronic signatures carry legal validity for general business agreements, purchase orders, freelance contracts, non-disclosure agreements, and standard consumer contracts. However, specific documents such as wills, family law orders, and court filings may require physical notarization or qualified cryptographic certificates. Always verify your specific local legal and statutory requirements.

Can I sign a multi-page PDF on different pages?

Yes. You can navigate between pages using the "Prev" and "Next" controls in the top toolbar. You can place your initials on page 1, checkmark terms on page 2, and add your full legal signature and date stamp on page 3. All stamps across all pages will be preserved and merged upon export.

Does FivoTools store my signature or documents?

No. Never. Your documents, signatures, and personal details are processed 100% locally within your browser's private memory sandbox. We do not transmit, log, or store your documents or signature graphics on any remote server.

Why should I flatten my signed PDF document?

Flattening converts dynamic, editable form fields and visual overlays into static, uneditable PDF content. This ensures that when you send the PDF to other parties, they cannot easily alter your entered text, modify dates, or move your signature stamp in standard PDF reader applications.

What is the difference between an electronic signature and a cryptographic digital signature?

An electronic signature (e-signature) is a visual mark, typed script, or symbol showing intent to agree to document terms, widely used for commercial and personal contracts. A cryptographic digital signature relies on Public Key Infrastructure (PKI) with X.509 certificates issued by a certified Certificate Authority to cryptographically seal the document. FivoTools provides client-side electronic signatures and form filling.
