Edit PDF: how it works
To edit a PDF, open the Edit PDF tool and add your file; you can add text, images, shapes, and freehand annotations, then download the edited PDF. All edits are applied in your browser and the file is never uploaded.
How to use Edit PDF
- Open the Edit PDF tool and add your PDF.
- Add text, images, shapes, or freehand drawings on any page.
- Download the edited PDF.
In your browser vs. uploading to a server
Best for quick annotations and additions without desktop software like Acrobat. For reflowing existing paragraphs, convert to Word first with PDF to Word.
Frequently asked questions
How can I edit a PDF for free without Acrobat?
- Open the Edit PDF tool, add text, images, shapes, or drawings on top of the page, and download; it is free and runs in your browser.
Are my files uploaded to a server?
- No. PDFER runs entirely in your browser using WebAssembly and JavaScript. Your files are read into memory on your device, processed locally, and never sent to PDFER or any third party. Closing the tab or leaving the tool erases them from memory.
