Frequently asked questions
Is this signature legally binding?
SimplyPDF provides electronic signatures. Depending on your jurisdiction and the type of document, this may or may not satisfy legal requirements for 'qualified' digital signatures.
Does it work on mobile?
Yes! You can use your finger or a stylus to draw your signature directly on your phone or tablet.
Can I sign multiple pages?
Currently, our tool allows you to place one signature on one selected page. For multiple signatures, you can run the finished file through the tool again.
About this tool
Sign PDFs three ways — draw with your mouse or finger, type in a signature font, or upload an image of your ink signature — and place it exactly where the document needs it. The print-sign-scan ritual dies here, and the document never leaves your device.
How to Sign a PDF
- 1
Open the document awaiting your signature — a contract, agreement, consent form, or offer letter.
- 2
Create your signature: draw it naturally, type your name in a script font, or upload a photo of your handwritten signature.
- 3
Position it on the signature line, apply, and download the signed document — ready to return in minutes, not days.
Why Sign with Wrklyst
- Contracts Never Uploaded
- Signing happens in your browser — documents at their most sensitive moment stay entirely on your device.
- Minutes Instead of a Print Shop
- No printer, scanner, or office required — sign from a laptop at home or a phone in transit.
- Free Without Per-Document Fees
- E-signature platforms charge monthly for what one document a quarter needs; this costs nothing per signature.
Signing Tips
- Photograph your ink signature once, in daylight on white paper, and reuse the image for consistent signing.
- Read the document before the signature page — speed of signing is no excuse for skipping terms.
- Add the date beside your signature when the form expects it; undated signatures cause processing bounces.
- Keep the signed copy you sent — your own record of exactly what you executed.
Frequently asked questions
Is a signature added this way legally valid?
In most jurisdictions, broadly yes — laws like the U.S. E-SIGN Act and eIDAS in Europe recognize electronic signatures for most agreements, and an image of your signature applied with intent to sign generally qualifies. Certain documents (wills, some real-estate deeds) have stricter requirements; for high-stakes agreements, confirm the counterparty accepts this signature form.
Which signature method should I choose?
Drawing works well with a trackpad, stylus, or touchscreen and looks most natural. Uploading a photo of your real ink signature gives the most authentic appearance — sign white paper, photograph it in good light. Typing in a script font is the fastest and is fine where the signature is a formality.
Can multiple people sign the same document?
Sequentially, yes — sign your fields, send the signed PDF onward, and the next party signs their line on the received copy using the same process. Each pass adds a signature over the accumulated document, exactly like a paper contract circulating for counterpart signatures.
How is this different from a certificate-based digital signature?
This applies a visual signature — the electronic equivalent of ink, appropriate for everyday contracts and forms. Cryptographic digital signatures additionally embed a certificate that detects any later modification, used in regulated filings and some government contexts. When a counterparty specifically requires certificate-based signing, they'll say so explicitly.
