Most everyday "signing" is simply placing a visible signature onto a document — agreeing to a quote, returning a form, initialling a letter. You can do that in seconds without printing, scanning or installing anything.
Three ways to sign
- Draw with a mouse, trackpad or touchscreen.
- Type your name in a signature-style font.
- Upload an image of your real signature on a white background.
How to sign a PDF in PDFelly
- Open the Sign tool and add your PDF.
- Create your signature by drawing, typing or uploading.
- Drag it onto the correct spot and resize it.
- Apply and download the signed file.
The document never leaves your browser — a real benefit when you are signing a contract or an offer letter.
Electronic vs. digital signatures
A visible (electronic) signature like this shows assent and is sufficient for the vast majority of business documents. A digital signature uses a cryptographic certificate to prove who signed and that the file has not changed since — required for some legal and government processes. Check what the recipient actually needs.
Tips
- Sign a copy and keep the original.
- Flatten the file afterwards so the signature cannot be dragged off.
- For forms with fields, you may want to fill the form first, then sign.
Three ways to create a signature
Drawing with a trackpad or touchscreen gives the most personal result and is ideal on a phone. Typing your name in a script font is fastest and perfectly acceptable for routine business documents. Uploading a photo of your real ink signature on white paper produces the most authentic look — crop it tightly and use good lighting so the background disappears cleanly.
Placing and sizing the signature
Zoom in before positioning so the signature sits neatly on the signature line rather than floating above or below it. Resize it to match the space provided; an oversized signature looks careless on a formal document. If a form needs initials in several places as well as a full signature, create both once and reuse them.
Electronic versus digital — know what's required
A visible electronic signature shows agreement and is enough for the vast majority of contracts, forms and letters. A cryptographic digital signature, which uses a certificate to prove identity and detect tampering, is required only for specific legal or governmental processes. Confirm what the recipient actually needs before assuming you require the heavier option.
Frequently asked questions
Is a typed or drawn signature legally valid?
For most everyday business documents, a visible electronic signature is sufficient. Some legal processes require a certificate-based digital signature — check the requirement.
How do I stop my signature from being moved?
Flatten the PDF after signing so the signature becomes part of the page and cannot be dragged off.
Can I sign on my phone?
Yes. Drawing a signature with a touchscreen works well, and the whole process runs in the mobile browser.
Is my document uploaded when I sign it?
No. Signing happens locally, so the contract or form never leaves your device.
A smooth signing routine for everyday documents
Most signing tasks — returning a quote, accepting an offer, initialling a letter — follow the same simple arc, and doing them in order keeps things tidy. If the document has fields to complete, fill those first so your details are in place. Create your signature once, choosing whichever method looks right for the document, and reuse it for any initials needed elsewhere. Position each signature precisely by zooming in, and size it to match the space rather than letting it dominate the page. When everything is in place, flatten the document so the signature becomes permanent and cannot be dragged off by whoever receives it, then save under a clear name and keep the unsigned original. Throughout, the file stays in your browser, which matters because the documents you sign are often exactly the ones you would least want sitting on a stranger's server — employment offers, agreements, financial forms.
