Who is it for?
It is for anyone who needs to sign a document without a printer or scanner — freelancers approving contracts, tenants returning a lease, employees signing an HR or consent form, and small businesses sending invoices. Imagine a rental agreement arrives by email: instead of printing it, signing by hand, and scanning it back, you open it in PDF7, drop your signature on the signature line, and email the signed PDF straight back in under a minute.

What is PDF Signing?
PDF signing means adding your signature to a PDF document — your real signature, drawn or typed, in your handwriting or as a typed name. It is the digital equivalent of "John Hancock"-ing a contract. We do not require fancy certificates or ID verification (though for legal contracts you may want a certified e-signature service); we just place your signature on the PDF where you want it, save it, done.
You can draw your signature with mouse/finger, type your name in a handwriting-style font, or upload a photo of your signature on paper (we recommend signing on white paper, photographing in good light, then cropping). Position it on any page, resize it, and save. The signed PDF can be shared, emailed, or printed.
There are three quick ways to sign with PDF7: draw your signature freehand with a mouse or your finger on a touchscreen, type your name and let a handwriting-style font render it, or upload a transparent PNG or photo of your existing signature. Once added, drag the signature to the exact spot — a signature line, an initials box, or a date field — and pull a corner handle to resize it so it sits neatly without overlapping nearby text. You can place the same signature on several pages or sign each page separately. Keep in mind that this produces an electronic signature image embedded in the PDF, not a certificate-based digital signature backed by a cryptographic ID. For everyday agreements that visible signature image is exactly what most people need.

Frequently asked questions
Are PDF7 signatures legally binding?
Yes for most informal contracts (rentals, simple agreements). For high-stakes legal documents (real estate, court filings) consider a certified e-signature service like DocuSign that uses PKI certificates.
Can I sign multiple pages?
Yes. Add a signature to any page individually, or copy the same signature to multiple pages.
Can someone alter my PDF after I sign?
A signed PDF can technically be edited unless you also lock it. After signing, use our Protect PDF tool to add a password and prevent edits.
Is my signature stored anywhere?
No. We process and discard. Your signature image lives only in browser memory until you save the PDF.
What file formats can I upload as my signature?
You can upload a PNG (a transparent PNG looks cleanest because no white box appears around it) or a regular photo of your signature on paper. For the sharpest result, sign in dark ink on white paper, take the photo in bright, even light, and crop tightly before uploading. Keep the image under a few MB so it loads instantly.
Can I add a date or my initials next to the signature?
Yes. Use the type option to add your initials or the date as text, then position that block beside your signature just like any other element. You can resize and drag it freely, so a full signature, initials, and a date can all sit on the same page.
