"Editing a PDF" means different things to different people: some want to change existing text, some to add notes on top, some to sign. Pick the right tool and it takes seconds. Here's a roadmap by need.
1) Change or delete existing text
If you want to actually remove text in a PDF and type new text, use the "Edit PDF" tool. Draw a box over the text to change, type the new text (leave empty to delete) and download.
Edit PDF — Truly delete and replace existing text — draw a box, type the new text, download.
2) Add text, notes or marks on top
To add text, highlights, boxes or drawings on top without touching existing text, the "Annotate PDF" tool is ideal. You can also use it to fill in blanks on forms.
3) Sign
To sign a document, use the "Sign PDF" tool to draw, type or upload your signature and place it anywhere on the page. Signing happens entirely on your device.
4) Fill forms
For forms with no fillable fields (flat), you can fill them by adding text directly on top — see our form-filling guide for detailed steps.
For confidential documents, annotating and signing run entirely on your device; your file doesn't go to a server. Real text deletion/editing is done on a secure server and the file isn't stored after processing.
