How to Sign a PDF Online for Free

Signing a PDF online is useful for forms, approvals, proposals, and routine agreements. The main requirement is not only adding a signature image, but also placing it accurately, reviewing the final document, and understanding whether the recipient requires a specific signature method.

Open PDF ME and choose Sign PDF. Select your document, draw, type, or add your signature, then position it in the correct area. Download the signed PDF and reopen it to confirm the signature placement and verify that every required field is complete.

Check the recipient's requirements before signing. Some legal, government, or regulated workflows may require a certified electronic signature platform rather than an inserted signature. Keep a copy of the final signed document.

PDF ME processes common PDF operations locally in your browser, so your document does not need to be uploaded to an external server. That is especially important for contracts, forms, invoices, and files containing personal information.

PDF ME is suitable for adding signatures to everyday PDFs quickly in your browser without installing software.
