How to edit a PDF in your browser (free)
Change existing text, add new content, and rearrange pages — entirely in your browser. Your file is never uploaded.
1. Open your PDF
Go to the editor and drag a PDF onto the window, or click to choose a file. It opens instantly because everything runs locally — nothing is sent to a server.
2. Edit existing text
Pick the Edit text tool and click a line. The original text is removed and replaced in a matching font, keeping its original colour. To re-wrap a whole paragraph, use the Edit paragraph tool.
3. Add new text, shapes, and images
Use the Text tool to type anywhere (choose a colour and size first), or add rectangles, lines, ellipses, arrows, polygons, freehand ink, callouts, and stamps from the toolbar. Insert a JPEG with the image tools. Drag to move, use the handles to resize, and arrow keys to nudge. Shift-click or drag a box to select several objects and align them.
4. Find & replace
Open search, type a word, and switch on the replace panel to swap text across the whole document — matching each line's original font and colour.
5. Rearrange pages
Drag pages in the sidebar to reorder them, and rotate, duplicate, insert, delete, crop, or extract pages as needed.
6. Save your file
Click Save to download the edited PDF. You can also optimise (compress) it or flatten it to images first.
