Is an electronic signature on a PDF legally valid?

In most cases, yes. The US E-SIGN Act and UETA give electronic signatures the same legal standing as handwritten signatures for most contracts and agreements. Some document types are excluded, including wills, certain real estate deeds, and court filings in some jurisdictions.

What is the difference between a drawn and a typed signature?

A drawn signature uses your mouse or touchscreen to create a freehand image of your signature. A typed signature renders your name in a cursive or handwriting-style font. Both are legally equivalent under E-SIGN and UETA for applicable documents.

When is an e-signature not enough?

Wills and testamentary documents, some real estate transactions, adoption papers, and certain court documents typically require wet signatures, notarization, or both. If you are unsure, check with the requesting party or a legal professional.

How to Sign a PDF Online for Free

Quick summary: Upload your PDF at totallyfreepdf.com, click Sign in the toolbar, create your signature using Draw, Type, or Upload, place it on the page, and download. Takes about two minutes. No account required.

Paying for DocuSign just to sign one lease agreement, or hunting for Adobe Acrobat's free tier, does not make sense when you need to get something signed quickly. This guide covers everything about signing PDFs in a browser for free: the three ways to create a signature, how placement and resizing work, and the parts of e-sign law you actually need to know.

Three ways to create your signature

After clicking the Sign button in the toolbar, a panel opens on the right side of the screen. You will see three tabs at the top: Draw, Type, and Upload. Each creates a valid signature image that gets embedded in your PDF.

Draw (most common)

The Draw tab gives you a canvas with the prompt "Sign here." Use your mouse, a trackpad, or your finger on a touchscreen to write your signature just as you would on paper. The signature pad captures pressure-sensitive lines in black or blue ink, tapering at the start and end of each stroke the way a real pen does. If it comes out wrong, click the Clear button and try again as many times as you need. Once it looks right, click "Place Signature" to drop it on the document.

On a phone or tablet, the drawing experience is much better than on a laptop trackpad. If you have a stylus, this is the time to use it.

Type

The Type tab renders your name in a handwriting-style font. Type your name in the text field, then click "Place Signature." This works well for people whose handwritten signature is just their name anyway, or for situations where legibility matters (some legal forms want a printed signature). It is quick and consistent.

Upload

If you have already scanned or photographed your signature as a PNG or JPG, the Upload tab accepts any image file. A transparent PNG works best because there is no white box around the signature when it lands on the document. A photo on a white background also works fine on most documents.

Tip: The best setup for a transparent PNG signature is to sign with a black marker on white paper, photograph it, then use a free background-removal tool like remove.bg before uploading. The result looks sharp on any document color.

Placing and adjusting the signature

After you click "Place Signature," a signature image appears on the current page. It floats as a movable element. Drag it to line up with the signature line on the form. You can tell when it is roughly in position because the signature block will visually overlap the line.

To resize, drag the small corner handle that appears at the bottom-right of the signature block. The image scales proportionally. Most signature fields on standard forms work well with a signature that is about an inch tall. Make it smaller for cramped spaces, a bit bigger if the signature area is generous.

If you need to sign multiple pages, navigate to the next page using the page panel on the left, then click "Place Signature" again on that page. Each page can have its own signature.

Downloading the signed document

Once the signature is positioned and you are satisfied with the form, click Download PDF at the top right. The signature is rendered permanently into the PDF as pixels. The recipient cannot remove or reposition it. The document looks the same in any PDF viewer.

The legal side of electronic signatures

For most everyday documents, electronic signatures are perfectly valid. Here is the short version of what the law actually says.

United States: E-SIGN Act and UETA

The federal Electronic Signatures in Global and National Commerce Act (E-SIGN), passed in 2000, gives electronic signatures the same legal effect as handwritten signatures for most contracts. All 50 states have also adopted the Uniform Electronic Transactions Act (UETA), which covers state-level transactions. Together, they mean that a signature you draw on a PDF and email to someone carries the same legal weight as a wet signature on paper, for the vast majority of agreements.

The law does not require any specific technology. You do not need DocuSign or a certified digital certificate for most documents. A drawn or typed signature is sufficient.

European Union: eIDAS

The EU's eIDAS regulation (Electronic Identification, Authentication and Trust Services) creates a similar framework for EU member states. A "simple electronic signature" under eIDAS covers drawn or typed signatures. For higher-stakes transactions, eIDAS also defines "advanced" and "qualified" electronic signatures that require additional verification, but those are specialized cases.

When e-sign is not enough

The following document types typically still require wet (handwritten) signatures, notarization, or both:

Wills, codicils, and testamentary trusts
Adoption, divorce, and certain family court documents
Real estate deeds (laws vary by state; many states now allow e-recording but check local rules)
Court filings in jurisdictions that require original signatures
Documents that a government agency explicitly requires in wet-ink form
Negotiable instruments (checks, promissory notes) in some contexts

When in doubt, check with the party requesting the signature. They will tell you if an e-signature is acceptable. For anything with real legal or financial consequences, ask a lawyer before assuming an e-signature will suffice.

Signing lease agreements, contracts, and HR forms

Rental agreements, employment contracts, NDA agreements, independent contractor agreements, and HR onboarding forms are all examples where e-signatures are routinely accepted. Landlords and property managers have been using electronic signatures for leases for over a decade. Most employers accept digitally signed offer letters and W-4 forms without any issue.

If you and the other party are signing remotely, the typical workflow is: one person fills and signs the PDF, downloads it, emails the signed PDF to the other party, who opens it in their own PDF editor (or in this tool), adds their signature, and returns the final copy. Both parties keep the fully signed document.

Does the signature prove who signed?

A drawn or typed signature in a browser-based PDF editor is visually similar to a handwritten one, but it does not carry a digital certificate identifying the signer. This is fine for most everyday agreements, where the practical circumstances (the email trail, the context of the transaction) establish identity well enough.

For situations where you need strong proof of identity, consider a service like DocuSign or Adobe Acrobat Sign that timestamps and certifies signatures with a digital certificate. Those services cost money, but they produce an audit trail that is harder to dispute. For a lease renewal or a freelance contract with someone you already know, a simple drawn signature is almost always sufficient.
