How it works
Open the PDF
Drop your PDF into the upload box above.
Upload your signature
Click Signature → Upload, pick your image, and toggle background removal if needed.
Place and download
Drag the signature into position, resize it, and download the signed PDF.
Bring in a signature you already have
If you've signed a piece of paper and taken a photo of it, you can drop that image straight into your PDF. The uploader trims the near-white background, keeps the ink crisp, and lets you place the result anywhere on any page.
Tips for a clean signature image
For the sharpest result, sign in dark ink on plain white paper, take the photo in even light, and crop it tight before uploading. The tool will handle the rest — soft-edge transparency, drag-and-resize handles, and pixel-accurate placement.
- Use black or dark blue ink on white paper
- Photograph straight-on, avoiding shadows
- Crop the image so the signature fills most of the frame
- Save as PNG when possible for the sharpest edges
Where the signature actually goes
The signature is drawn on top of the PDF at the exact coordinates and size you see on screen — no rasterising, no resolution loss on the rest of the document. When you download, the original page content stays intact and your signature sits on top as its own image layer.
Frequently asked questions
What image formats can I use for the signature?+
PNG and JPG/JPEG up to 10 MB. PNG with transparency looks cleanest; JPGs on white backgrounds get an automatic background-removal pass.
How do I get my signature transparent?+
Enable 'Remove white background' when you upload. The editor turns near-white pixels transparent with a soft edge so the signature blends into the page.
Can I resize the signature after placing it?+
Yes. Every placed signature has drag handles for repositioning and corner handles for proportional resizing.
Can I add the same signature to multiple pages?+
Yes. Add the signature once, then place it on each page — the editor keeps your saved signature ready between placements.
Is the signature saved anywhere?+
No. It lives in memory in the current browser tab and disappears the moment you close the tab.
