How to sign a PDF with SignPrivate
- Open your file. Drop a PDF, JPG or PNG onto the page or choose it from your device. Images are wrapped into a PDF automatically.
- Create your signature. Draw it with a mouse, finger or stylus, type your name in a handwriting font, or upload a photo of your signature on paper and let the tool remove the background.
- Place and download. Click where the signature belongs, drag it into position, add the date or your name, then download the flattened, signed PDF.
Why your file really never leaves your device
Everything runs in the browser
The PDF is read, rendered, signed and rebuilt by JavaScript running in this tab. There is no server component that could receive your document, so there is nothing to delete afterwards either.
You can check it yourself
Load the page, switch off your Wi-Fi, and the tool still works. Open your browser's network inspector while signing and you will see no requests carrying your file.
No account, so no profile
There is nothing to sign up for, so there is no account tied to your documents, your email or your signature. An optional "remember my signature" setting stores it in your own browser only.
What you can do
Sign PDFs of any length
Contracts, leases, consent forms, invoices, NDAs, school forms. Multi-page documents are rendered page by page and you can sign several pages.
Sign scans and photos
A photo of a paper form from your phone or a scanned JPG works the same way as a PDF. How to sign a scanned document.
Add date, name and text
Insert today's date with one click, add your printed name, title, initials or place, and position each item independently.
Clean, flattened output
The signature becomes part of the page, exactly like a printed and scanned copy, so it opens correctly in any PDF viewer and cannot be dragged away.
Phone, tablet and desktop
Draw with your finger on a phone or tablet, or with a trackpad on a Mac or Windows laptop. Nothing to install.
Free, with no catch
No daily task limit, no "premium" watermark, no email required to download. The site is supported by a single ad and clearly marked affiliate links.
When you need more than a signature
SignPrivate is built for the common case: a document lands in your inbox, it needs your signature, and you want it back out in a minute without creating an account or handing the file to a company. It produces a simple electronic signature, which is accepted for most everyday agreements.
If you need to collect signatures from several people, send reminders, verify the signer's identity or keep a tamper-evident audit trail, you need a full e-signature service. Those are paid products such as SignWell, Dropbox Sign or DocuSign. Links marked as affiliate links may earn this site a commission at no extra cost to you.
Frequently asked questions
Is SignPrivate really free?
Yes. There is no paid tier, no task limit and no watermark. The site is funded by one advertisement and by affiliate links to paid e-signature services for people who need features this tool does not have.
Where is my file stored?
Only in the memory of your browser tab, and only while the page is open. It is never sent to a server. When you close the tab, it is gone. The signed PDF is saved wherever your browser saves downloads.
Is a drawn or typed signature legally valid?
In the United States, the European Union, the United Kingdom and most other countries, a signature does not lose legal effect just because it is electronic. For most contracts, forms and letters a drawn signature is enough. Some documents, such as wills, deeds or notarised acts, need stricter forms. Read our guide to the legal status of drawn signatures. It is general information, not legal advice.
Does it work offline?
Yes. After your first visit the tool is cached, so it opens and works without an internet connection. You can also install it like an app from your browser's menu.
Which file types can I sign?
PDF, JPG, PNG and WebP. Images are converted to a PDF page of the same proportions before signing. Word documents are not supported directly; export them to PDF first.
Is there a file size or page limit?
No fixed limit. Very large scans may be slow on an old phone because the work happens on your device, but typical contracts of a few hundred pages are fine.
Can other people sign the same document?
Not through this site. Sign your part, download the PDF and send it on; the next person can open it here and add their signature. If you need to track who signed when, use a full e-signature service.
Why is there an advertisement on a privacy-focused tool?
Hosting a static site is cheap, but not free, and development takes time. One ad slot keeps the tool free without accounts or paywalls. The ad never sees your document because the document never leaves your device.
