A professional-looking PDF signature goes a long way. Whether it's a freehand drawing that captures your natural handwriting, a neatly typed name in an elegant script font, or a high-res scan of your actual ink signature, the result gets embedded as a crisp PNG directly into the PDF page. That means it renders identically in every viewer — Adobe Acrobat, Preview, Chrome's built-in reader, Firefox, or anything else your recipient happens to use. The entire process happens inside your browser, so your signature data only exists in two places: your browser's memory while you're working, and the final downloaded file. Nothing else.

## How it works

1. **Upload Your PDF** — Drag and drop or click to select the PDF document you need to sign
2. **Create Your Signature** — Draw freehand, type with handwriting fonts, or upload a signature image
3. **Place & Download** — Click on the PDF to position your signature, resize it, choose pages, and download

## Use cases

- **Formal Correspondence**: Add a polished signature to recommendation letters, reference letters, and official company communications
- **Legal Declarations**: Sign sworn statements, affidavits, and statutory declarations with a clear, identifiable mark
- **Creative Sign-Offs**: Approve design proofs, marketing collateral, and publication drafts with a quick signature
- **Medical Orders**: Add authorized signatures to prescriptions, lab requisitions, and referral forms

## Tips

- **Build a Signature Library**: Keep a folder with different signature images: a formal full name, a set of initials, and a casual first-name version. Grab whichever fits the document.
- **Test in Two Viewers**: Open the signed PDF in Chrome and in Preview (or Adobe Reader) to make sure the signature renders correctly in both.
- **Follow Placement Conventions**: Legal documents usually expect the signature bottom-right on the last page. Follow whatever convention the form specifies.
- **Pick One Color and Stick With It**: Consistency matters. Choose black or dark blue and use it across all your signed documents so your signature is always recognizable.

## FAQ

### What makes a signature look professional in a PDF?

Consistency and sizing. Use the same signature image each time, pick a dark ink color, and resize it to fit the space provided. A clean, properly-sized signature looks far more professional than a wobbly one-off drawing.

### Could someone copy my signature from the signed PDF?

The signature is a raster image embedded in the page, similar to a photograph. It carries the same copy risk as any printed signature. For tamper-proof signing, certificate-based digital signatures exist, but they're a different technology.

### Does compressing the PDF afterward affect the signature?

At normal compression levels, the signature stays crisp. Very aggressive compression might soften it slightly, but it'll still be perfectly legible.

### How do I get a transparent background?

Drawn and typed signatures automatically have transparent backgrounds. For uploaded images, use a PNG with transparency — most background-removal tools can convert a photo of your signature in seconds.

## Problems solved

- Signatures that look different in different PDF viewers
- Recreating your signature from scratch every time you sign a new document
- Figuring out which drawing app can export a transparent PNG for signing
- Worrying about where your signature image ends up after uploading it to a cloud tool

## Stats

- **Crisp PNG** embedded directly in the PDF page
