What Is an Online PDF Editor?
An online PDF editor lets you modify PDF documents directly in your web browser without installing any software. Unlike simple annotation tools that only allow freehand drawing, a full PDF editor supports adding formatted text, inserting images, and drawing on any page. Edits are embedded into the PDF structure so the resulting file can be viewed in any PDF reader. This tool processes everything client-side using JavaScript, so your documents remain private and are never uploaded to a remote server.
How to Use This Tool
Start by uploading a PDF file. The editor displays each page with four editing modes: Draw for freehand strokes, Text for placing editable text boxes, Image for inserting pictures, and Select for repositioning or resizing elements. Switch between modes using the toolbar at the top. In Draw mode, choose a pen color and width, then draw directly on the page. In Text mode, click anywhere on the page to place a text box and type your content. In Image mode, upload an image file to insert it onto the current page. Use Select mode to drag elements to a new position, resize images, or delete items. When finished, click Save to generate the edited PDF and download it.
Adding Text to PDFs
The text editor supports six standard PDF fonts: Helvetica, Helvetica Bold, Times Roman, Times Bold, Courier, and Courier Bold. You can set the font size from 6 to 120 points and choose any color using the color picker. Text boxes are placed exactly where you click on the page and can be repositioned later in Select mode. Multi-line text is supported — simply press Enter within a text box. The text is rendered using PDF standard fonts, ensuring consistent appearance across all PDF viewers without embedding external font files.
Inserting Images into PDFs
You can insert PNG, JPEG, or WebP images into any page of your PDF. Uploaded images are placed at a default size of 30 percent of the page width with the aspect ratio preserved. Switch to Select mode to drag the image to the desired position or resize it using the corner handle. Images are embedded directly into the PDF file structure, so the resulting document is fully self-contained. This is useful for adding logos, signatures, photos, diagrams, or watermarks to existing documents.
Privacy and Security
This PDF editor runs entirely in your browser using client-side JavaScript libraries. Your PDF files and images are never uploaded to any server. All rendering, editing, and PDF generation happen locally on your device. This makes the tool suitable for editing sensitive documents such as contracts, financial records, and personal files. Once you close or refresh the page, all data is discarded from browser memory. For maximum privacy, you can use this tool offline after the page has loaded.
