Note: This tool adds a visual signature image only. It does not create a legally binding digital signature or certificate.
No. This tool adds a visual image of your signature to the PDF. It does not create a cryptographic digital signature with a certificate. For legally binding e-signatures under India's IT Act, use a DSC (Digital Signature Certificate) issuing authority.
For typed signatures, the background is transparent. For uploaded images, enable the "Remove white background" option — it threshold-removes near-white pixels so only the ink is visible.
No. Everything runs in your browser using PDF.js and pdf-lib. Your PDF never leaves your device.
Your document and your signature are never uploaded. The signature overlay is rendered using pdf-lib entirely inside your browser — the signed PDF is assembled in memory and downloaded directly to your device. Sensitive documents such as offer letters, freelance contracts, and service agreements stay completely private throughout the signing process.
No account is required. There are no credits to purchase, no monthly limits, and no watermark on the signed output. Sign a single document or use the Batch Sign panel to apply the same signature to multiple PDFs in a single session — all without creating an account or entering an email address.
The signing tool works equally well on mobile and desktop. Draw your signature with a finger on a touchscreen, type it on a keyboard, or upload a scan of your handwritten signature from your phone's gallery. The result is the same professionally embedded signature regardless of the device you use.
A drawn or typed signature placed on a PDF is equivalent to a wet ink signature and is sufficient for internal documents, freelance contracts, offer letters, NDAs, and most informal business agreements. For documents requiring a legally recognised Digital Signature Certificate (DSC) under the IT Act 2000 — such as MCA filings, tax audit reports, and e-tendering submissions — you need a certificate issued by a licensed Certifying Authority (CA) and a dedicated DSC tool.
Yes — use the Batch Sign panel to apply the same signature to multiple PDFs in a single session. Upload your files, position the signature once, and the tool applies it to every uploaded document. Each file is processed and downloaded separately so you can confirm the placement on each before the batch runs.
Yes — the signature is permanently embedded as an image or vector shape in the PDF page, not stored as an interactive annotation. It renders identically in Adobe Reader, Apple Preview, Chrome's built-in PDF viewer, and all other compliant viewers. The appearance does not change based on reader settings or platform.
Yes — select "Custom pages" and enter the page numbers or ranges you want, for example "1, 3, 5-8". Only those pages will receive the signature. Select "All pages" to sign every page — useful for initialling every page of a multi-page contract. The "Current page only" option signs just the page currently shown in the preview.
