How to Sign a PDF Online Free (No Sign-Up, No Upload)
Your landlord emails the lease and needs it signed — today. The old ritual is miserable: print it, sign it, scan it back, hope the scanner behaves. The modern alternative is worse: a paid e-signature service with an account, a trial, and a renewal you forget to cancel. For the everyday “please sign and return” email, you do not need either of those things.
The free Sign PDF tool lets you place your signature on any PDF right in your browser: draw it, type it, or upload an image of your real signature. Everything happens on your own device — no account, no subscription, no document sitting on someone’s server.
How to sign a PDF online, step by step
Step 1 — Open the signer. Go to the Sign PDF tool on AllConvert. It runs entirely in your browser.
Step 2 — Add your PDF. Drop the file into the upload box and you will see its name and details inside the box, so you know it loaded.
Step 3 — Create your signature. Three options: draw on the pad with your mouse, finger, or stylus (pick an ink colour); type your name and let it render in a script style; or upload a PNG or JPG of your real signature — a transparent PNG blends in best.
Step 4 — Place it. Click anywhere on the page to drop your signature, drag it into position, and use the width slider to size it. Add your printed name and the date as real text under it if you like.
Step 5 — Download the signed copy. Save produces a brand-new signed PDF. Your original file is never modified — it stays exactly as it was.
Why this is enough for most signatures
Most “sign and return” requests just need your visible signature on the page — a lease, a consent form, a school permission slip. This tool does exactly that, in seconds, without an account or a per-envelope fee. Your signature image lives on your device, the document lives on your device, and the whole transaction is between you and your own browser tab.
Honest limits — what this is not
It is a visible signature, not a cryptographic one. This places a signature image on the page — no certificate, no tamper-proof seal. If a document explicitly requires a certified digital signature, you need a dedicated signing service.
Password-protected PDFs are refused. Encrypted files are turned away with a clear message.
Draw boldly. A tiny timid drawing scaled up looks wobbly — draw big and confident on the pad for the cleanest result.
Print sharpness has limits. Your name and date print as crisp vector text, but the drawn part of the signature is an image — fine for screens and normal printing, not for a billboard.
The short version
Open the tool, add the PDF, make your signature, place it, download. No sign-up, no upload, no subscription — and the landlord gets his lease back today.
Combining documents first? The Merge PDF tool joins your files before signing, and Compress PDF shrinks the signed copy for email — same free, no-upload idea. For editable documents, there is PDF to Word.
