How to Sign a PDF for Free (2026 Guide)
A contract lands in your inbox, the deadline is today, and printing it just to scribble your name and scan it back feels absurd in 2026. It is. You can drop a signature onto any PDF straight from your browser in well under a minute — no printer, no app to install, and no account to create. This guide walks through the three ways to build a signature, how to place it cleanly, how to keep it from being nudged later, and what to do when something looks off.
Three Ways to Create Your Signature (and When to Use Each)
Before you place anything, you need a signature to place. There are three ways to make one, and the right choice depends on the device you're on and how polished you want it to look.
Draw it
Sign with your mouse, trackpad, or — far easier — a finger or stylus on a touchscreen. A drawn signature looks the most like your real one, which matters on contracts and anything a person will actually eyeball. It's fiddly with a mouse, though; if you're on a laptop with no touchscreen, the typed option usually looks cleaner.
Type it
Type your name and let it render in a handwriting-style font. This is the fastest route and the most legible, which is ideal for routine approvals, internal sign-offs, and forms where nobody is scrutinizing the curve of your signature. The trade-off: it won't match the signature on your ID or bank records.
Upload an image
If you already have a photo or scan of your handwritten signature, upload it and reuse it everywhere. This gives you a consistent, authentic mark across every document. For the cleanest result, sign in dark ink on plain white paper and crop tightly — and see the troubleshooting note below about removing the white box behind it.
Electronic Signature vs. Digital Signature: What You're Actually Adding
These two terms get used interchangeably, but they aren't the same thing:
- An electronic signature is the visible mark you draw, type, or upload. It represents your intent to agree. This is what the steps below add, and it's what the overwhelming majority of everyday documents need.
- A digital signature is a separate, cryptographic layer that uses a certificate to mathematically prove who signed and that the file hasn't been altered since. It's issued by a certificate authority and is what some regulated or enterprise workflows specifically require.
For contracts, NDAs, consent forms, applications, and approvals, an electronic signature is broadly recognized — for example under the U.S. ESIGN Act and UETA, the EU's eIDAS regulation, and Canada's PIPEDA. A few document types, like wills or certain government filings, may still demand an ink signature or a certificate-based digital signature. This is general information, not legal advice — if a specific document's requirements are unclear, check with the party requesting it.
How to Sign a PDF: Step-by-Step
Step 1: Open your document
Go to EditPDFs.app and drag your PDF onto the upload area, or click to browse. It opens in the editor with your pages shown as you'll see them in the final file.
Step 2: Open the signature tool
Select the signature tool from the toolbar. You'll be prompted to create your signature using one of the three methods above — do this once, and you can reuse it on every spot in the document.
Step 3: Place and size it
Click where the signature belongs and a movable box appears. Drag it onto the signature line and pull a corner to resize. Aim to have it sit on the line rather than floating above it, and keep it roughly the height of the surrounding text so it doesn't overwhelm the page.
Step 4: Add the date and initials
Many documents also need a date, initials on each page, or a printed name beneath the signature. Add those now — you can place additional signatures and initials anywhere, as many times as the document requires.
Step 5: Download the signed PDF
Export the file. The signature is baked into the PDF itself, so it travels with the document and displays correctly wherever it's opened.

By default, a placed signature stays a distinct object that a recipient could, in theory, select and reposition in some editors. If you're sending a signed contract and want the signature fixed in place, flatten the PDF before sending. Flattening merges the signature into the page so it behaves like printed ink — just keep an unflattened copy if you might still need to edit it.
Troubleshooting Common Problems
The signature is too big, too small, or blurry
Resize it by dragging a corner rather than stretching one side, which keeps the proportions intact. If an uploaded image looks fuzzy, the source was low-resolution — re-scan or re-photograph it larger and crop, rather than blowing up a small image.
The signature landed on the wrong page
Scroll to the correct page first, then place it — signatures are added to whichever page is in view. If one's already misplaced, drag it to the right spot or remove it and place a fresh one.
The signature box has a white rectangle around it
That happens when an uploaded signature image has a solid white background instead of a transparent one. Use a PNG with a transparent background, or sign on clean white paper and crop tightly so the box blends into the page.
It won't let me sign a secured or scanned PDF
If the file is password-protected, you'll need to remove the password first (you must know it). Scanned PDFs sign fine — you're placing a signature on top of the image, so no text editing is involved.
The signature shifted after I downloaded it
This is almost always a different PDF viewer rendering an unflattened object slightly differently. Flattening before export locks the position so it looks identical everywhere.
Signing on Specific Devices
- Windows / Mac: The browser steps work identically in any modern browser. Drawing with a trackpad is doable but slow — typing or uploading an image usually looks tidier on a laptop.
- iPhone / iPad: Open the site in Safari and draw with your finger, or use an Apple Pencil on iPad for a signature that's genuinely close to your pen-on-paper version.
- Android: Use Chrome the same way — drawing with a finger or stylus works well on a phone or tablet.
When People Reach for This
Signing a PDF online tends to come up for:
- Employment contracts, offer letters, and NDAs
- Rental and lease agreements
- Consent and permission forms (medical, school, travel)
- Invoices, quotes, and purchase approvals
- Any form that arrives as a PDF and has to go back signed
A Note on Privacy
The documents you sign are often the most sensitive ones you handle — salary figures, home addresses, medical details, financial terms. Many online signing services upload your file to their servers to process it. With EditPDFs.app, signing happens entirely in your browser, so the document and your signature never leave your device.
Frequently Asked Questions
Is it really free to sign PDFs?
Yes. There's no fee, no premium tier, and no cap on how many documents you sign — and no watermark on the result.
Is an electronic signature legally binding?
For most everyday agreements, yes — electronic signatures are recognized under laws like the ESIGN Act, UETA, and eIDAS. Some specific documents (such as wills or certain government forms) may still require ink or a certificate-based digital signature. This isn't legal advice; confirm if you're unsure.
Do I need to create an account?
No. Open the site, upload your PDF, sign, and download — there's no signup.
Can I add several signatures or initials to one document?
Yes. Once your signature is created you can place it as many times as needed, plus initials, dates, and a typed name on any page.
Can someone remove or move my signature afterward?
To fix it firmly in place, flatten the PDF before sending — that merges the signature into the page so it can't be selected and dragged. Keep an unflattened copy if you might need to make changes later.
Can I sign a scanned document?
Yes. You're placing a signature on top of the page image, so scanned PDFs work the same as text-based ones.
Are my files uploaded anywhere?
No. On EditPDFs.app everything runs locally in your browser, so your document and signature stay on your device.
