Edit PDF

Edit PDF is a browser-based PDF tool on PDFToolsBase. Edit PDF: add text overlays at numeric X/Y coordinates. No live drag/click — placement uses numeric inputs. To use it, upload or drop your PDF and view the result directly in your browser — no signup and nothing to install.

Add new text overlays to PDF pages by numeric position, in your browser. Free, private, no signup — this adds new text and does not edit existing text.

Heads-up on the placement UI. Text is placed using numeric X / Y inputs (PDF points, bottom-left origin — the same units Acrobat uses) or one of nine anchor presets (top-left / top-center / top-right / middle-left / center / middle-right / bottom-left / bottom-center / bottom-right). It does not let you click on a live preview to drop the text where you tapped — that would require mounting a full interactive PDF editor in the browser, which we deliberately did not build. Workflow: type the text, pick a preset or enter X/Y, click Process, look at the result, adjust if needed.

About this Edit PDF

Add custom text anywhere on your PDF with our edit pdf tool. Type your text, pick the page and position (X, Y coordinates in PDF points), choose a font size, and place it.

The text is added as a real PDF text object, so it is usually selectable and searchable in PDF readers. The output is not a fully tagged accessibility-remediated PDF.

Your privacy is the default. Your selected files are processed in your browser and are not uploaded to our server; all processing happens client-side using browser PDF libraries such as pdf-lib and PDF.js where needed. Closing the tab clears the working session from this page; downloaded files remain on your device.

This tool is free to use with no signup required. Large files may be limited by your browser’s memory and device performance. Part of PDF Tools Base, a privacy-first collection of 161 PDF utilities. Bookmark the page for next time, and explore related tools in the footer below.

Frequently asked questions

Is Edit PDF safe to use?

Yes. Everything happens in your browser. Your selected files are processed in your browser and are not uploaded to our server. Closing the tab clears the working session from this page; downloaded outputs remain on your device until you delete them.

Do I need to register or sign in?

No. No account, no email, no sign-up. Open the page and start using the tool immediately. Free to use, no signup needed.

Is there a watermark on the output?

No. PDF Tools Base never adds a watermark or branding to your output. Your final file is clean — just what you produced from the original.

Is there a file size limit?

There is no fixed limit. Files are processed in your browser, so RAM, page count, and file complexity affect what is feasible. Phones may struggle with large PDFs; try splitting first or use a desktop browser.

Does this work on mobile devices?

Yes. The tool works on all modern mobile browsers: Chrome on Android, Safari on iOS, Firefox, Edge, Brave. The drag-and-drop also accepts files from your phone’s file manager.
