Is my document really not uploaded?

Correct. The PDF is rendered and rewritten entirely in your browser. You can confirm it: open your browser's network tab before you drop the file in, and you will see no request carrying it.

Do I need an account?

No. No signup, no subscription. Open a file, sign it, and pay only when you want the copy without the watermark.

Will the signed file still be searchable?

Yes. The marks are added to the original PDF rather than a picture of it, so the existing text stays selectable and searchable and the file size stays sensible.

Can I sign on my phone?

Yes, and drawing with a finger is usually better than with a mouse. The signature pad takes touch and stylus input directly.

Can several people sign the same document?

You can place as many signatures as you like, but each person has to open the file in turn on their own machine, since nothing is stored here. For a routed signing order with reminders, use a service built for that.

What about a password protected PDF?

A file that needs a password to open cannot be read here. Remove the protection in the application that created it, or open it with the password and save an unprotected copy first.

The signed file without the watermark. The editor, the signature pad and a watermarked copy are free every time.

Does it change the pages or the size?

No. Page dimensions, rotation and the existing content are untouched. Only your marks are added.

Firma un PDF sin subirlo a ningún sitio

PDF, hasta 20 MB

Los documentos que más necesitamos firmar son los que menos ganas tenemos de entregar: un contrato de trabajo, una oferta, un alquiler, un formulario con un número de identidad. Todas las herramientas populares te piden subir el archivo a un servidor antes de poder poner una marca, y luego cuentan cuántos llevas antes de que empiece la suscripción.

Esta abre el PDF en tu navegador. Las páginas se dibujan en tu equipo, tu firma se dibuja en tu equipo y, al descargar, el archivo se escribe en tu equipo. No se envía nada, y puedes comprobarlo en la pestaña de red.

Las marcas se escriben dentro del archivo original, no sobre una imagen de él, así que el documento que envías sigue siendo el que recibiste: el texto se puede seleccionar y las páginas conservan su tamaño.

How it works

Open the PDF
Drop the file in. It is rendered page by page in your browser using the same engine your browser uses to show a PDF, and it is never sent anywhere.
Make your signature once
Draw it with a mouse, a finger or a stylus, type it, or upload a photo of your ink signature. It is trimmed to its edges so it sits properly in place.
Place it where it belongs
Click the page to drop it, then drag to move and pull the corner to resize. You can also add initials, a text field, today's date or a tick for a checkbox.
Download the signed file
The marks are written into the original PDF, so the existing text stays selectable and the file stays the same document rather than a flattened image.

How this differs from the usual tools

The features are similar. What happens to your document is not.

Typical online signer

Where the file goes: Uploaded to a server
Free tier: One or two documents a day
Price after that: A monthly subscription
Account: Usually required to download
The output: Often a flattened image
Audit trail: Recorded by the service

Here

Where the file goes: Stays in your browser
Free tier: The whole editor, every time
Price after that: One payment for the file
Account: None
The output: The original file with marks added
Audit trail: Not recorded, see below

What you can put on a page

Everything is positioned in the page's own coordinates, so it lands where you put it whatever size your screen is.

Your signature
Drawn, typed or uploaded. Trimmed to its own edges so there is no invisible box around it.
Initials
The same signature at a smaller size, for the corner of every page that asks for them.
A text field
For a name, an address, a reference or anything the form left blank.
Today's date
Filled in already, in your own locale's format.
A tick
For a checkbox. Drawn as strokes rather than a font character, so it appears the same in every PDF reader.
Anywhere, on any page
Multi page contracts included. Drag to move, pull the corner to resize.

Is a signature like this legally binding?
In most countries an electronic signature on an ordinary business document carries the same weight as an ink one, and a signature you draw here is the same kind of mark you would make on paper. The common cases, a freelance contract, an offer, a supplier form, a school letter, are exactly what this is for. What this deliberately does not do is record an audit trail. Services like DocuSign log who opened the document, from which address, and when, and that log is the thing you are really buying from them. It matters when a signature might be disputed, when several parties sign in sequence, or when a rule requires a witness or a qualified certificate. So: ordinary documents here, high value or contested ones somewhere built for it. That is a straight answer rather than a sales pitch, and it is the same reason nothing is uploaded. None of this is legal advice.
