Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To sign a PDF with this tool, open the document, create your signature, drag it onto the page where it belongs, then export the signed copy. The whole flow happens in the browser, so the file is processed on your device and never sent to a server.
You can build a signature three ways: type your name and pick a style, draw it with a mouse or touchscreen, or upload an image of an existing handwritten signature with a transparent or white background. The same signature can be reused and placed on several pages of the same document.
This tool places a visible signature image into a fresh PDF export, which is the right fit for everyday forms, approvals, and routine handoff documents. It does not issue a certificate-based digital signature, so it will not embed a cryptographic identity certificate or a tamper-evident audit trail.
For most personal and business documents, a clear visible signature on a clean signed PDF is exactly what the recipient expects. If you need a legally certified digital signature with identity verification, use a dedicated certificate-authority service instead.
Yes. Sign PDF runs client-side in your browser, so the source PDF and your signature are processed on your device and are never uploaded to a server. This makes it safe for contracts, agreements, and personal paperwork you would rather not send to a cloud service.
Because the work is local, nothing is stored after you close the tab. The exported signed PDF is created on your device and saved directly to your downloads.
Short answers for the questions people usually have before trying a utility like this.
Yes. Sign PDF is completely free with no account, watermark, or page limit, and it runs entirely in your browser.
No. The signing happens locally in your browser, so the PDF and your signature stay on your device and are never uploaded.
Yes. You can type, draw, or upload an image of an existing handwritten signature, then place it anywhere on the PDF.
No. It places a visible signature into the PDF export rather than issuing a certificate-based digital signature with identity verification.
Yes. You can place your signature on one page or repeat it across several pages of the same document before exporting.
