How to capture a signature that cuts out cleanly

  1. Sign with a black or dark blue pen on plain white paper. Felt tip or gel pens give the strongest line.
  2. Photograph it in daylight or under an even lamp, straight on, with no shadow from your hand or phone.
  3. Crop to the signature before dropping it in. Less paper means the model concentrates on the ink.
  4. Drop it above, check the thin strokes with the slider, and download the PNG.

Why this page exists

A signature is one of the few images you genuinely should not upload to a random website. Every other signature tool sends your photo to a server. DropBG runs the model on your device, so the image is processed and discarded in your browser's memory. You can confirm this with the network tab in developer tools.

Using the result

  • PDFs. Insert the PNG as an image in Preview, Acrobat or any PDF editor. Transparency lets it sit on the signature line without a white box.
  • Email. Add it to your signature block at roughly 150 to 200 px wide.
  • Documents. In Word or Google Docs, insert the image and set text wrapping to "in front of text".

Tip. If the strokes look thin or broken, re-photograph with a thicker pen rather than trying to fix the cutout. The model keeps what it sees; it cannot thicken ink.

Why people are switching to DropBG

remove.bg's standalone website shuts down on December 1, 2026 and moves into Canva. If you just want a background gone, without a design suite and a login, this is the tool.

Private by design

The model runs inside your browser. Your photos never touch a server, which also means there is nothing for us to store, leak or train on.

Genuinely unlimited

No credits, no "1 free HD download per month", no watermark. Processing happens on your hardware, so there is no per-image cost to pass on.

Fast after the first run

The model is cached by your browser once. From then on, most photos finish in one to three seconds, and it keeps working without an internet connection.

Questions

Is it safe to use for a legal signature?

The image never leaves your device, so it is as private as a tool can be. Whether a pasted image counts as a legal signature depends on the document and jurisdiction; e-signature services exist for the cases where it matters.

Can it remove the lined paper or notebook lines?

Faint lines usually go. Dark ruled lines that touch the signature may be kept where they cross the ink. Plain white paper avoids the problem.

Can I make the signature blue or another colour?

Not here. The tool keeps the original ink colour. Any image editor can recolour the transparent PNG afterwards.

Is this really free?

Yes. No credits, no watermark, no daily cap, no account, and no ads. The remover runs on your own device, so giving it away costs us nothing. An optional one-time Pro unlock pays for the site.

Is my image uploaded anywhere?

No. The AI model downloads to your browser once and every image is processed on your own device. Open your browser's network tab while you use it: you will see the model download and nothing else.
