Somebody emailed you a contract as a PDF, and the oldest workflow in the world says: print it, find a pen, sign, scan, email back. There's a better way that takes ninety seconds and no hardware — and for most documents, the free version is all you need. The trick is knowing which documents deserve the $150-a-year platform and which just need your signature on a page.
Our Sign PDF tool does exactly this, entirely in your browser — the file never uploads, which matters more than people assume (more on that below).
Legally, almost never. The federal ESIGN Act defines an electronic signature broadly: an electronic sound, symbol, or process attached to or logically associated with a record, executed with intent to sign. In plain terms — the mark counts if you meant it. Courts have accepted typed names, checkbox clicks, email replies saying "agreed," and drawn squiggles.
Practically, there are still reasons to prefer one form:
| Method | Looks like | Best when |
|---|---|---|
| Draw (mouse/finger) | Handwritten-ish stroke | The counterparty expects "a signature" |
| Type in script font | Clean cursive rendering | No steady hand; small screens |
| Upload a photo of your real signature | Your actual ink signature | Branding-conscious documents; you have one scan |
| Checkbox / click-to-agree | No visual mark | Software flows, terms acceptance |
What actually gets disputed in the rare cases that end up in court isn't the aesthetics of the mark — it's who made it and whether they intended to be bound. That's an evidence question, which is where the platform tier earns its money.
DocuSign, Dropbox Sign, Adobe Acrobat Sign, and their peers sell something different from signing: proof infrastructure. Email verification of each signer, sequential routing, timestamped audit trails, tamper-evident seals, and a certificate of completion that summarizes who signed what, when, and from what IP. If a deal could ever end up in front of a judge or an auditor — multi-party business contracts, real estate closings in some states, anything regulated — that paper trail is what you're paying for.
For the other 90% of signatures — the permission slip, the freelance SOW between people who already know each other, the internal approval — a locally-signed PDF with your signature on it is every bit as valid a contract. The law doesn't grade tools by price.
Upload a contract to a free signing site and you've handed a complete executed document — names, addresses, prices, terms, signatures — to a server you know nothing about. Some free services retain files, some monetize aggressively, and a data breach at a signing service is a breach of signed contracts. Browser-based signing removes the question structurally: if the PDF is read, rendered, and written by JavaScript in your tab, there is no copy on anyone's server, and you can confirm that in ten seconds with the browser's network panel. For NDAs, employment paperwork, medical forms, and anything financial, that's the right default.
None of these force you to buy anything. A drawn signature placed with a local tool is a simple electronic signature, valid for the vast majority of everyday agreements.
Draw, type, or upload your signature. Drag it onto any page, optional date stamp, download. No account, no upload, no watermark.
Open Sign PDF →Signing usually sits at the end of a document pipeline, and the neighbors are worth knowing. Documents still in Word convert first — our Word to PDF converter handles .docx locally, and HTML to PDF typesets pasted markup the same way. Selling a car? The bill of sale generator produces the document you'll most often need to sign, and the invoice generator covers the payment side. All of them run in-browser.
For everyday signatures, skip the printer and skip the upload box: create the mark once, place it locally, keep the contract on your own machine. Reach for a platform only when proof — identity, routing, timestamps — is the product you actually need. And either way, read what you're signing; no tool fixes that part.
No. DocuSign, Dropbox Sign, and similar platforms are needed when multiple parties must sign in sequence, when identity verification matters, or when you want a certificate of completion with timestamps. If you just need your signature on a document you already have — a lease addendum, a permission form, a client agreement — a browser-based signer that places your drawn signature on the page produces a normal PDF with your signature on it, free, in about a minute.
Under U.S. law, the form of the mark rarely matters — ESIGN defines an electronic signature as any electronic sound, symbol, or process attached to a record with intent to sign. A typed name, a drawn squiggle, a checkbox on a website, and clicking 'I agree' can all qualify. What gets litigated is whether the right person executed it with intent, which is about evidence, not ink aesthetics.
Think twice before you do. An upload-based signer gets a full copy of an executed contract — parties, prices, signatures, addresses — and free services vary enormously in retention and resale practices. A browser-based signer that runs on JavaScript never transmits the file, which is the safer default for anything with personal or financial detail. You can verify: open the network panel and watch for uploads.
An electronic signature is the mark — the image, the typed name, the click. A digital signature is cryptography wrapped around the document: a certificate that mathematically proves who signed and that not a byte changed since. Digital signatures are common in regulated workflows (some EU qualified signing, government filings). For everyday contracts, the electronic kind plus ordinary evidence of agreement is the norm.
