How to sign PDF online
To sign a PDF, open the document, create a signature by drawing with your mouse or finger, typing your name in a script font, or uploading an image, then click on the page to place it. Resize and move it as needed, add a date if you like, and click Save. The signed PDF is never stored.
Step by step
Three steps. Most files take a few seconds.
Step 1: Open your PDF
Drop the file onto the page.
Step 2: Create your signature
Draw it, type it, or upload a photo of your signature. White backgrounds are removed automatically.
Step 3: Place and save
Click where the signature belongs, adjust the size, add a date or initials, and click Save PDF.
Why use this tool
Three ways to sign
Draw on a touch screen, type with a handwriting font, or upload a scan.
Reusable
Your signature is kept on this device only, so you can sign the next document faster. Clear it any time.
Private
Contracts and agreements are never stored.
Your file is never stored
Your document is used only to produce the result you asked for. Once the download is ready and you leave the page, the file is gone. There is no copy to keep, no account that holds it, and nothing to delete later.
That makes it safe for invoices, contracts, bank statements, ID scans, medical records, and anything else you would rather keep to yourself.
Read how it worksFrequently asked questions
How do I sign a PDF for free without Adobe?
Open Sign PDF, add the document, draw or type your signature, place it, and click Save PDF. No subscription or account is needed.
Is this a legally binding electronic signature?
In many countries a simple electronic signature, such as a drawn signature placed on a document, is valid for most agreements. It is not a certificate-based digital signature. For regulated documents, check the requirements that apply to you.
Can I sign on my phone?
Yes. Drawing with a finger on a phone or tablet works well, and the file is never stored.
Where is my saved signature stored?
On this device only. It is never sent to us. Use Clear signature to delete it.
Is it safe to use this with confidential documents?
Yes. Your file is used only to produce the result you asked for and is never stored. We do not keep copies, read the contents, or share them with anyone. Once you download the result and close the page, the file is gone.
Is this really free?
Yes. Every tool on PDF Editor Box is free to use without signing up. We may show an ad outside the work area, but we never gate features, add watermarks to your output, or limit how many files you process.
