Your file stays on your device
The document is opened by a viewer running in this tab. The work is done in this browser tab by a PDF engine compiled to WebAssembly: the file is read from your disk into the page's memory and the result is saved straight back. To check, open your browser's developer tools and watch the Network tab while the tool runs. No request carries your file.
Questions
Do I need to install anything?
No. It runs in the browser, on a computer or a phone.
Can I change the text already in the PDF?
No. You can add text, highlights, shapes, drawings and notes on top of a page; the text already on it is not rewritten.
Will other PDF readers show my highlights and notes?
Yes. Highlights and notes are saved as standard PDF annotations, and shapes and added text become part of the page.
