Edit and Annotate PDF adds a short line of text onto a page of an existing PDF — a note such as Approved, Paid, Reviewed, a date, a reference number, or a name. Full PDF editors are powerful but heavy, and often paid. For the common job of stamping one clear note in the right area of a page, a small focused tool is faster: load the file, type the note, pick the page, position it with two sliders, and download an updated copy.

Positions are set as percentages of the page, because PDFs come in many sizes. The horizontal slider measures from the left edge and the vertical slider measures from the bottom edge, which is how PDF coordinates work. There is no live preview in this simple tool, so positions are approximate: the note text also has its own width, and dense pages can be hard to judge blind. The honest workflow is to add the note, open the result, and nudge the sliders and run it again on the original if the placement needs adjusting. Each run takes seconds.

The note is drawn in a bold dark red so it stands out from body text. Your file is processed entirely in your browser and is never uploaded, and the original remains unchanged.

How to use

Click the file box and choose the PDF you want to annotate.
Type the text of your note, keeping it short so it fits neatly on the page.
Set the page number where the note belongs.
Move the horizontal and vertical sliders to estimate the position, and set a font size.
Click Add Text and Download, open the result, and fine-tune the sliders on the original file if needed.

Frequently asked questions

Why is there no preview?

Keeping this tool light and fully browser-based means it writes the note directly without a rendering step. The download-and-check loop is quick, and your original file is never overwritten, so adjusting is safe.

Can I add several notes at once?

One note is added per run. To add more, run the annotated result through the tool again for each extra note, choosing its page and position each time.

Can I edit or delete existing text in the PDF?

No. This tool adds new text on top of a page; it cannot change, move, or remove content already in the file. For that you would need a full PDF editor.

Is my document private?

Yes. Annotation happens locally in your browser, so your PDF never leaves your device.
