Fonctionnement
How does this tool work?
Add a handwritten signature saved as PNG or JPEG to a specific PDF page. The document and signature image stay in your browser and are not uploaded to a server. The PDF and image are loaded directly in your browser. The preview lets you choose the page and define the image position and size visually. When you generate the result, the engine applies those coordinates to the PDF page and creates a new file locally. The source document remains unchanged, and neither the PDF nor the image needs to be uploaded to a processing server.
Use cases
Administrative documents
Add a visual element to a form or document before saving and sending it while keeping the original source file unchanged.
Precise visual placement
Position an image, logo, stamp or signature with the preview instead of guessing coordinates or dimensions.
Confidential processing
Modify a PDF containing personal or professional information without transferring the document or image to a remote processing service.

Tips and best practices
