Guide
Why use E-Sign PDF
E-Sign PDF is built for one specific case: a PDF that already has a signature field in it — the kind you get from an HR system, a template built with an AcroForm, or a form someone else prepared for you to sign. Upload it, sign, and download. There's no dragging or positioning, because the field already marks where your signature goes.
If your PDF doesn't have a signature field yet — most everyday PDFs don't — use Sign PDF instead. It lets you draw, type, or upload a signature and place it anywhere on any page, no pre-built field required.
Once signed, the form is flattened, so the signature becomes a permanent part of the page rather than an editable field someone could later change.
One step when the field already exists
No positioning to get right — upload a PDF with a signature field, sign it, and it lands exactly where the form was built to hold it.
Draw or upload your signature
Sign with a mouse or finger on the signature pad, or upload an image of your signature if you already have one saved.
Form flattened on save
After signing, the field is locked in as part of the page content — it can no longer be edited or re-signed by opening the form again.
Free, no account needed
Upload, sign, and download without creating an account. Save to a workspace later only if you want to track or reuse the document.

What happens to your file
Your file is used once, then removed
The upload is used to fill the signature field and produce your download — it isn't kept afterward unless you save it to a workspace.
No account required
Upload, sign, and download without signing in. Create an account only if you want to store or reuse the document later.
Nothing is copied into a shared template
The signature field you fill exists only in your document — it isn't reused for other files or visible to anyone else.
FAQ
Frequently asked questions
?What kind of PDF does this actually work on?
One that already contains a signature form field — typically a PDF exported from a form builder, HR platform, or template tool. If you open your PDF and there's no defined signature field to fill, this tool won't find one to sign; use Sign PDF instead, which places a signature anywhere on any PDF without needing a pre-built field.
?E-Sign PDF vs Sign PDF — which one do I want?
Use E-Sign PDF when your PDF already has a signature field built in and you just need to fill it. Use Sign PDF for everything else — any PDF, any page, signature placed wherever you click.
?Is my signature stored anywhere?
No, not unless you choose to save the signed PDF to a workspace. The upload is used to produce your signed download and isn't retained afterward.
?Does this replace certified, audit-trailed e-signature platforms?
No. This produces a visual signature written into the page, suitable for everyday forms and low-risk agreements. Contracts that need a certified audit trail or multi-party identity verification belong on a dedicated e-signature or CLM platform.
?Is it free?
Yes — uploading, signing, and downloading is free and doesn't require an account.
?Can I sign on my phone?
Yes, the signature pad accepts touch input on phones and tablets, though reviewing a multi-page form is easier on a larger screen.
Before you send it
Signed PDFs deserve accountability — track opens or publish as a completion form.
