PDF Image Signer is a fast, free online tool for putting an image of your signature onto a PDF — one document at a time or hundreds in a batch — plus a handful of everyday PDF utilities like splitting and merging. It runs in your browser, with no software to install and no account required to get started.
Most people don't need a heavyweight e-signature suite to drop their signature into a letter, an invoice, or a form. They need to do it quickly, get a clean result, and not worry about where the file went afterwards. The tools that promise this often hide a catch: they upload your document to a server you know nothing about. We wanted the simple, common case handled well — and handled privately.
This is the principle the whole tool is built around: your documents are processed in memory to perform the operation you asked for, and are not written to disk or retained on our servers afterwards. We don't view, share, or sell your files.
There is exactly one deliberate exception, and we call it out plainly: the optional, Pro-only "Chat with your PDF" feature sends the document you choose to a third-party AI provider to generate answers — but only when you turn it on and consent for that session. It is off by default and never used for any other tool here. The full details are in our Privacy Policy.
You can use the core tools as a guest. Creating a free account raises the limits, and a Pro subscription removes ads and lifts the quotas and file-size caps for heavy users. The current allowances are shown in the app and on your account page. Our FAQ answers the common questions about plans, formats, and limits.
