Add text and signatures to PDF

How to add text and a signature to PDF

Choose a document from your device. Use the text tool to place a box where you need it, or draw a signature. Change font, size, color and alignment, move added objects or rotate pages. Review the preview and download a new copy.

Your document stays on your device

Processing happens locally in your browser. The tool does not send your document, filename, text or signature to a server. There is no automatic cloud or browser-storage save. Closing a document clears the workspace; copies you already downloaded stay on your device.

What to know before editing

The tool adds content over a PDF; it does not change existing text. Added text is saved as a print-quality image and is not searchable or copyable as text. A white cover is visual only, not secure redaction. Encrypted files are not supported. Editing a digitally signed document invalidates its signature in the copy. Input guards are 100 MB and 999 pages; performance depends on the device and document.
