The paper came back as many gray shapes
That happens with a plain camera photo. Scan the page with your phone's document scanner instead, which whitens the paper.
Sign a sheet of paper, scan it with your phone and upload it. Get smooth vector paths, then turn on Remove background when downloading to leave the signature on transparency.

A single-color ornament with dozens of cut-outs, traced as one black path with smooth, closed outlines.
The short answer
Upload a scan of your signature and convert it to SVG. The result is editable vector artwork that stays smooth at any size. For a clean scan on plain paper, turn on Remove background under Download options before saving. Check the downloaded file and remove any enclosed white pieces you want to leave empty.
Step by step
Five minutes with a pen and your phone.
A felt-tip or gel pen gives a solid line. Sign a little larger than usual.
Use your phone's document scanner, such as Scan Documents in the iPhone Notes app or Scan in the Google Drive app. It whitens the paper, so only the ink is traced. A flatbed scanner works too.
Crop close to the signature, then drop the image onto the box at the top of this page.
Zoom into joins, loops and the thin ends of strokes, where a soft photo shows first.
Turn on Remove background under Download options, then save the SVG. Enclosed areas of the same color are kept; remove those pieces in your editor if you want open loops inside the lettering.
Where to use it
Keep the SVG as the master copy and export other formats from it when a tool needs them.
| Where | How | Tip |
|---|---|---|
| PDF documents | Place the SVG, or a PNG exported from it | Keep it at the size of a real signature |
| Email signature | Use a PNG exported from the SVG | Many email apps do not show SVG |
| Website | Use the SVG directly | Recolor it to match your text |
| Print and merchandise | Send the SVG or a PDF | Sharp at any size |
| Cutting machines | Upload the SVG | Very thin strokes may need thickening to cut |
A signature file is easy to copy. Only share it where you would share a scan of your signature.
A straight answer
The photo matters more than anything else. Good light and a dark pen do most of the work.
A plain photo still traces, but the paper's shading comes back as many light shapes. A document scan avoids that.
Troubleshooting
That happens with a plain camera photo. Scan the page with your phone's document scanner instead, which whitens the paper.
Use a finer pen and sign larger, so the gaps between strokes survive.
The ink was too faint. Sign again with a darker pen.
Turn on Remove background under Download options before downloading. If the paper appears as many shaded shapes, use a document scan for a more even background.
Sign on plain paper, or delete the line shapes afterwards.
Change the overall size rather than the stroke. The signature is a filled shape, so scaling keeps its proportions.
FAQ
Yes. Use its document scanner, such as Scan Documents in the iPhone Notes app or Scan in Google Drive, and crop close to the signature. A plain camera photo also works, but the paper's shading comes back as extra light shapes.
Turn on Remove background under Download options before saving the SVG. This removes the outer paper background from a clean scan. Enclosed white areas are kept, so remove those pieces in your editor if they should be transparent too.
SVG stays sharp at any size and can be recolored. PNG is more widely accepted by email and document tools. Keep the SVG as your master and export a PNG when a tool needs one.
Yes. The ink is a vector path, so you can give it any color in your editor.
