Online PDF Editor for Text, Images, and Markup
Most PDF tasks require more than just reading; you often need to add labels, insert logos, or highlight specific text to clarify your point. This online PDF Editor provides six versatile tools that handle every common editing scenario. Use the Add Text feature to type and position content anywhere via a draggable overlay, which is perfect for headers or manual form entries. The Add Image tool supports PNG and JPG uploads, giving you the freedom to scale and place logos or reference photos exactly where they belong.
Highlight Key Sections with Adjustable Opacity
Place semi-transparent color blocks over your pages with the highlight tool while keeping the underlying text perfectly legible. Six preset colors help organize your markup by category, and the opacity slider offers precise control from 10% to 80% transparency. Since each highlight acts as a draggable overlay, you can adjust its position precisely before it becomes a permanent part of the document.
Draw Freehand Markups on Any Page
Turn your mouse or trackpad into a digital pen with the drawing tool for complete creative control over your markups. Pick any color and set the stroke width from 1 to 10 pixels to get the exact style you need. Every stroke appears in real time on the sidebar canvas, and when you are ready, you can move the artwork onto the page preview. A quick click of the Apply button embeds your drawings permanently into the PDF.
Page Numbers and Cropping
In addition to basic editing, this tool simplifies structural tasks that frequently come up during document prep. Stamp sequential page numbers across your entire file in one click using your preferred format and placement. For documents with scanner artifacts or messy margins, the cropping tool provides the precision you need by letting you drag a resizable rectangle over the preview.
Stamp Page Numbers in Multiple Formats
You can pick from several numbering formats, including standard numeric (1, 2, 3), lowercase Roman numerals (i, ii, iii), or dash-wrapped styles (- 1 -, - 2 -). These can be placed in any of six standard positions across the top or bottom of your pages. Adjust your font size anywhere from 8pt to 24pt and check the instant sidebar preview to make sure everything looks right before you commit. All page numbers use Helvetica to guarantee correct display in every PDF viewer.
Crop Pages to Remove Unwanted Margins
Scanned documents and slide exports often feature extra whitespace that looks messy and wastes paper. The cropping tool fixes this by letting you select the exact area you want to keep with a draggable rectangle. When you apply the changes, the internal PDF metadata updates so your new boundaries remain consistent across every viewer and printer.
Free PDF Editor for Students, Professionals, and Teams
Whether you are reviewing a thesis, marking up a contract, or finalizing a report, every essential editing feature is here for free with no signup required. Since the application runs entirely in your browser, your documents never leave your local machine. This makes the editor a secure choice for handling sensitive records, financial statements, or internal memos. Your exported files carry no watermarks, and there are no limits on how many PDFs you can process.
No Signup, No Watermark, No File Limits
Get immediate, full access to every editing mode, color option, and export feature without dealing with account walls or usage limits. Your session data is wiped from memory the moment you close the browser tab. Privacy is baked into the architecture, ensuring your security doesn't just depend on a written policy.
Client-Side Processing for Complete Privacy
The editor uses pdf.js for rendering and pdf-lib for modifications, with both libraries running locally in your browser. Your information stays private because no network requests ever transmit your document data. This local processing model is ideal for managing sensitive materials like medical records, legal agreements, or proprietary company data.
