PDF signatures
Sign PDFs Online
Use bunbunpdf to place signatures, initials, and signing dates directly on a PDF. The signing workflow runs in your browser, so the document does not need to be uploaded to a server.
Workflow
- Open a PDF from your device.
- Choose the signature tool and create a typed or drawn signature profile.
- Place signatures, initials, or dates on the page.
- Export an editable PDF or flatten signatures into the final pages.
Controls
- Save multiple signature profiles locally for repeated signing work.
- Adjust signature size before placing it.
- Use date formatting controls for signing dates.
Local editing
PDF editing runs locally in the browser with JavaScript and WebAssembly. PDF files, text, filenames, form values, signatures, and user-entered content are not uploaded.
