To edit a PDF, upload it to DIT ToolsKit's Edit PDF tool, click anywhere on the page to add a text box, then drag it into place and adjust the font size. Save when you're done to download the edited PDF.
What is Edit PDF?
Edit PDF lets you add new text directly onto any page of an existing PDF — useful for filling in a detail, adding a note, or labeling a diagram — without needing the original source file or PDF editing software installed.

- Upload the PDF you want to edit.
- Click anywhere on the page to add a text box, then type your text.
- Drag the text to reposition it, or adjust its font size.
- Click "Save edited PDF" and download the result.

Privacy & security
Edit PDF processes your file directly in your browser using client-side code. Your file is never uploaded to DIT ToolsKit's servers, so it stays on your device throughout the entire process.
Limitations
- This tool adds new text on top of a page rather than modifying existing PDF text, since most PDFs don't store text in an editable format.
- Only font size is adjustable per text box; color and font family use a standard readable default.
- Password-protected PDFs need to be unlocked first, since the tool can't read pages it can't open.
Frequently asked questions
Can I edit text that's already in the PDF?
This tool adds new text on top of the page rather than modifying existing PDF text — most PDFs don't store text in an editable format, so overlaying new text is the reliable way to make additions.
Can I change the text color or font?
Currently you can set the font size for each text box; color and font family use a standard readable default.
Can I edit a multi-page PDF?
Yes — use the page navigation arrows to move between pages and add text to any of them before saving.
How can I edit a PDF file for free without installing software?
Open the file in this Edit PDF tool — it runs entirely in your browser, so there's nothing to install and no cost, even for multiple documents.
