Edit & Annotate PDF Files Online
Free & private · no signup · no watermarks · files deleted in 1 hour
Need to add notes, highlights, or text to a PDF without the original source file? Our Edit PDF tool lets you annotate and mark up your PDF documents online. Add text boxes anywhere on the page, highlight existing content, and insert comments — all without converting the file or needing the source application that created it. Changes are rendered directly into the PDF output.
This is ideal for reviewers marking up documents before returning them, teams annotating technical drawings, students highlighting and noting textbooks, and anyone who needs to add visible instructions or corrections to a PDF. The editing interface works in the browser on desktop and mobile — no software installation required.

Frequently Asked Questions About Edit PDF
Everything you need to know about our Edit PDF tool
Yes, completely free. Our Edit PDF tool has no hidden costs, no watermarks, and no registration requirement. You can process as many files as you need, each up to 100MB, at no charge. We believe professional PDF tools should be accessible to everyone — students, freelancers, and businesses alike.
Your files are fully protected. All uploads and downloads use 256-bit SSL/TLS encryption during transfer. Processing happens on our isolated Hetzner server infrastructure in Germany — your file is never shared, analysed for commercial purposes, or stored longer than necessary. Every uploaded and processed file is automatically and permanently deleted within one hour of processing.
Supported file types: This tool accepts PDF files up to 100MB each. For files larger than 100MB, use our Compress PDF tool first.
Portable Document Format
Yes — works on any device. The interface is fully responsive and tested on desktop, tablet, and mobile. Touch-friendly upload areas, drag-and-drop support on desktop, and mobile-optimised buttons mean you get the same experience whether you are on a MacBook, an iPad, or an Android phone. No app download is ever required — open your browser and go.
The tool adds new annotations and text boxes on top of existing content — it does not reflow or directly alter original text. You can place a new text box anywhere on the page to add notes, corrections, or additional content. Existing text in the PDF cannot be edited in the traditional word-processor sense because PDF text is stored as positioned character streams, not editable paragraphs. For full text editing, convert to Word first using our PDF to Word tool, edit, then convert back.
