Add Image to PDF

What Can You Do with Add Image to PDF?

The Add Image to PDF tool embeds a JPG or PNG image at a specified position on any page of a PDF document. Common uses include adding a digital signature to a contract, stamping a company logo on a letterhead, placing an official seal on a certificate, inserting a headshot photo on a CV, or adding an image watermark. The tool provides a live canvas preview so you can position and size the image precisely before downloading the modified PDF.

How to Add an Image to a PDF — Step by Step

1. Upload your PDF — drop it onto the Step 1 area or click to browse. The PDF renders in a preview canvas.
2. Upload your image — JPG or PNG. For signatures, use a transparent PNG for the best result.
3. Set the target page — if your PDF has multiple pages, select which page receives the image.
4. Position and size the image — adjust X, Y, Width and Height using the sliders. The canvas preview updates live.
5. Adjust opacity — reduce below 100% for a watermark effect or to make the image semi-transparent.
6. Click Download — the modified PDF downloads immediately.

Signature Best Practices

PNG vs JPG for Signatures — Which Format to Use

• Sign on white paper with a dark pen (blue or black ink photographs best)
• Use good lighting — avoid shadows across the signature
• Photograph with your phone camera in landscape mode for a wider image
• Use a background remover (free online tools are widely available) to create a transparent PNG
• Set opacity to 100% for a natural-looking signature on any page background
• Use the Lock aspect ratio option to resize without distorting the signature shape

Common Uses for Embedding Images in PDFs

• Digital signatures: Sign contracts and agreements — for a full annotation workflow, combine this with our PDF Annotator tool to also highlight and mark up the document and agreements without printing, signing and re-scanning
• Company logos: Brand documents, proposals and reports with your company logo
• Official seals: Add notary, government or institutional seals to certificates
• Rubber stamps: Add APPROVED, RECEIVED, PAID or similar status stamps
• Headshots: Add a profile photo to a CV, ID card or attendance register
• Image watermarks: Use a semi-transparent logo as a watermark — for text-based watermarks like CONFIDENTIAL or DRAFT, use our dedicated Watermark PDF tool instead as a watermark across a page

Privacy — Your Files Stay on Your Device

Both your PDF and image are processed entirely in your browser using PDF.js and pdf-lib. No file data is transmitted to any server. This is important for confidential contracts, legal documents and any files containing proprietary logos or personal signatures.
