PDF only · Max 100MB📱 The PDF editor works best on a desktop or laptop. Open this page on a larger screen for the full experience.
Use the annotation toolbar to add text, draw with the pen tool, highlight sections, draw rectangles, insert images, and sign documents. All annotations are baked into the exported PDF at full quality.
Combine multiple PDFs. Drag thumbnails in the sidebar to reorder pages. Rotate sideways scans. Delete pages you do not need. All changes preview instantly before export.
The exported PDF preserves original content at full quality. Text stays sharp, images stay at original resolution. Annotations are permanently embedded. No watermarks. No recompression.
Your file never leaves your device. All editing happens entirely inside your browser using PDF.js and pdf-lib. Nothing is sent to any server. Groew has no visibility into your documents at any point. This makes it safe for sensitive documents: contracts, financial reports, medical records, and client files.
You can add text, draw freehand, highlight areas, add shapes, insert images, and add signatures using the annotation toolbar below the main toolbar. These are added as a visual layer on top of the PDF and exported at full quality. Editing the original text already embedded in the PDF is not possible — PDFs store text as drawn paths, not editable strings.
Each PDF can be up to 100MB. This covers the vast majority of documents including multi-page reports, scanned books, and large presentation decks. Very large scanned documents with high-resolution images may take a moment to load and render in the browser.
The editor is designed for desktop and laptop screens. The thumbnail sidebar, canvas area, and toolbar all need a wider viewport to be usable. On mobile you will see a notice directing you to open the page on a larger screen. The tool works best on a screen at least 1000 pixels wide.
No. The exported PDF preserves original page content at full quality. pdf-lib copies pages exactly as-is without re-encoding images or compressing content streams. Your text stays sharp and your images stay at their original resolution. The exported file size may differ slightly from the original because pdf-lib rebuilds the PDF structure, but image and text quality is identical.
