How to sign a PDF online without uploading it
Open your document and the Sign tool is already selected. Click the page where the signature should go and a small window asks how you want to sign: draw it with a mouse, finger or stylus, type your name in a handwriting style, or upload a picture of a signature you already have on paper. Confirm, and the signature lands on the page where you clicked. Drag it to move it, pull a corner to resize it, then press Download PDF. The signed file is built on your own device, so the document is never sent to a server.
Placing the signature well
Zoom in before you place it so it sits exactly on the signature line. Use the arrow keys to nudge it by a point, or hold Shift for ten. If the document has several signature lines, create the signature once and reuse it: signatures you have made in this session stay available for one-click placement on the other pages. You can also add your printed name or the date next to it with the Text tool in the full editor.
What kind of signature is this?
This tool puts an image of your signature onto the page, the same thing as signing a printout and scanning it. That is accepted for many everyday documents such as rental forms, permission slips, quotes and internal approvals. It is not a certificate-based digital signature, so it does not prove who signed or detect later changes. If a contract or authority specifically requires a qualified or certificate-based signature, use a service that provides one.
Tips for a clean result
- Draw slowly on a large screen for a smoother line; on a phone, turn it sideways for more room.
- If you upload a photo of a signature, use dark ink on plain white paper in good light.
- Keep a copy of the unsigned original and download the signed file under a new name; this page adds -signed to the file name for you.
- Check the signed PDF in your viewer before sending it on.
Privacy
Your PDF is opened, changed and saved entirely inside your browser. It is not uploaded, stored or shared, and nothing is kept once you close the page. You can confirm this in your browser network tab while you work.
Frequently asked questions
Is my document uploaded when I sign it?
No. The PDF is opened, signed and saved inside your browser. Nothing is sent to ConverterMaster or anyone else, and your signature is not stored after you close the page.
Is a signature added here legally valid?
It is an image of your signature placed on the page, equivalent to signing a printed copy. Whether that is accepted depends on the document and your country, and it is not a certificate-based digital signature. For contracts that need one, use a dedicated e-signature service. This is general information, not legal advice.
Can I sign on my phone?
Yes. Draw with your finger, or type or upload your signature. The editor works on phones and tablets, although a larger screen makes placing it easier.
Can I sign several pages or add initials?
Yes. After you create a signature it can be placed again on any page with one click, and you can create a second small signature for initials.
Can I sign a password-protected PDF?
Not here. Files with an open password or editing restrictions cannot be rewritten. Save an unprotected copy in your PDF viewer first if you have the password.
Will the signature look the same in other PDF viewers?
Yes. It is written into the page itself, so it appears the same in Acrobat, Chrome, Edge, Preview and mobile viewers. It cannot be moved after you save.
