What is it?Sign PDF (Stamp) is a PDFLean security & privacy tool: Apply a typed or hand-drawn signature onto a PDF — basic self-signing, fully local.
TL;DR: Apply a typed or hand-drawn signature onto a PDF — basic self-signing, fully local. Processing runs entirely in your browser — your file is never uploaded; basic self-signing does not constitute legally binding e-signatures.
This tool stamps a signature or seal onto a PDF with adjustable position, size, and page coverage. Processing runs entirely in your browser — the document is not uploaded, and no account is required. The output is a signed-looking PDF for internal approvals, evidence of review, or visual certification. Key limitation: this is basic visual self-signing, not a compliant digital signature with a verified certificate; for legally binding signature requests with audit trails, use the dedicated e-signature workflow.
About this tool
Everything here happens in your browser, so the file you load is the only copy that exists. Apply a typed or hand-drawn signature onto a PDF — basic self-signing, fully local. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Practical limits apply (see the on-page limits); it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: see the on-page limits; Privacy: the file never leaves the device.

FAQ
Will my file be uploaded?
No. Processing runs entirely in your browser — your file is never uploaded, and closing the page clears it immediately.
Are there any limits?
Basic self-signing is not a legally compliant e-signature (see Electronic Signature for signing workflows); files up to 10MB.
Is the signature legally binding? How secure is it?
Processing runs entirely in your browser — signatures and documents are never uploaded. This tool provides basic visual self-signing (stamping typed or drawn signatures into a flattened PDF), suitable for internal routing; for legally binding workflows with multi-party signing and audit trails, use Electronic Signature.
Can I process multiple files in bulk?
A single tool page handles one task at a time; for bulk work use the Batch Processing workflow and add this tool as a step to run a whole set at once.
Is the processed file still editable?
The output is a new PDF with the signature stamped and flattened; your original file stays untouched. Once flattened into the document, the signature cannot be removed within this tool, so please keep a backup of your original.
