Why sign PDFs with ILikePdf?
Most online PDF signers upload your documents to their servers before adding a signature. For contracts, NDAs, legal documents, or financial forms, this is a privacy risk. ILikePdf processes everything locally in your browser. Your PDF and your signature never travel over the network.
You can also draw your signature using a touchscreen or stylus for a natural signing experience, or type your name and apply it in an elegant cursive font. No account creation, no daily limits, and no watermark on any output file.
