What you have to hand while you work

Why it works

Draw it once.

Your signature is kept in this browser and offered every time after. Drawing with a finger is the worst part of signing, so you only do it once.

It lands on the line.

Place it and it snaps to the signature line it finds. Arrow keys move it a pixel at a time when the last two pixels matter.

It works on a phone.

Including the drawing. Turn the phone sideways for a steadier hand — the tool says so at the moment it helps.

The usual version of this errand is worse than it needs to be. A form arrives as an email attachment, and the software wants an account, or an app install, or a subscription to place a signature on a line — for something that takes eleven seconds once the tooling stops arguing.

This does the eleven-second version. Open the document, use the signature you saved last time, tap the line, send it back. If you have never been here, drawing takes a moment and is then done forever, because your signature is kept in this browser and offered on every document afterwards.

Two details make the difference between usable and irritating. The first is snapping: signature lines are findable in a PDF, so placing a signature near one puts it on it, rather than leaving you dragging by hand at 100% zoom. The second is nudging — arrow keys move a placed signature a pixel at a time, because occasionally the automatic answer is very slightly wrong and there is nothing more frustrating than a tool that will not let you fix it.

On a phone the whole flow is designed rather than adapted. The form opens from the attachment, the fields are filled one at a time in a control big enough to actually tap, the saved signature is offered before the drawing pad, and when it is finished, downloading comes first with sharing offered right beside it — because the errand was never “get a file into the Downloads folder”.

There is no watermark, no page limit, and no count of how many documents you have signed this month. The document does not leave your device.

One case is worth naming, because it fails quietly. If your signature is a photo of ink on paper, or a scan, the picture carries the paper with it — placed on a form it arrives as an opaque white rectangle sitting on top of the line, and nothing here can see through it. What you want is the same image with a transparent background. removebackgrounds.ai, which is ours, does that step and hands back a PNG; upload that instead and it places clean, with the line still visible underneath.

We will not tell you whether your signature is legally binding, because that depends on where you are and what you are signing, and we are not the right people to answer it.

How it goes

  1. Open the document.

    Drop it here, or open it straight from an email attachment on a phone.

  2. Choose your signature.

    Use the one you saved last time, or draw a new one.

  3. Put it where it goes.

    Tap or click the line. It snaps into place; nudge it if you want it slightly different.

  4. Download or send it back.

    When you are done, downloading comes first and sharing the result straight back is offered right next to it — that was the errand.

What you can check for yourself

Watch the network while you work — nothing leaves this device on the default path. Then go offline and keep working — it all still runs. The two-minute checks live at how your files are handled.

Frequently asked questions

In many places a drawn signature is accepted the same way an ink one is, but it depends entirely on your country and the document. We cannot advise you on that, and we would rather say so than imply otherwise.

In this browser, on this device. Not on a server, and not in an account — there are no accounts. Deleting it takes one tap in Settings.

Yes. Typed, drawn, or an image of a signature you already have.

Yes — leave the document fillable rather than making it permanent when you download, and it says which is which.

Yes. Signing never needs the network.

Yes, from the same menu, and both remember their position between pages.
