What changes
New text is appended to page content. Existing text remains underneath and is not securely removed or replaced.
Edit PDF with added text
Place visible text on selected PDF pages using precise millimetre offsets. Existing content is preserved and never uploaded.

Add new text at an exact PDF position
This focused editor places one new text line at top-left millimetre coordinates on selected pages. It supports printable ASCII; other characters become question marks. It does not rewrite existing paragraphs.
For a reliable result
- Load the PDF and choose destination pages.
- Enter text, colour, size and measured x/y offsets.
- Render or open the result and confirm exact placement.
Check the download
Verify rotated pages and make sure the added line does not cover a form field or signature.
Know before processing
This is not a full layout editor. Complex scripts, embedded-font matching and editing existing glyphs are outside its scope.
Quick answers
- Can I change words that already exist in the PDF?
- No. This focused editor adds a new text line at measured coordinates. It does not identify, reflow or replace existing paragraphs and embedded fonts.
- Can added text securely hide confidential content?
- No. Existing content remains underneath and may still be selectable or recoverable. Use the secure redaction tool when information must be removed.
Add a new text line without rewriting the PDF underneath
This editor adds a short visible text line at a measured position. Use it for a review note, reference label or status such as Reviewed copy. You choose its wording, font size, colour and location; the same line can be applied to one or several selected pages.
It is a text-overlay tool, not a paragraph editor. It does not replace existing words, reflow a document or match the original embedded font. The original page content stays underneath the new text. Adding a correction beside a value can explain it, but placing new text over an old value does not remove the old information.
Decide whether a text overlay is the right change
| Your situation | Recommended approach |
|---|---|
| You need a short extra label in an empty part of the page. | Use this tool and start with one page. Check the downloaded placement before repeating the same line across pages with a different layout. |
| An existing paragraph, figure or form answer must change. | Edit the source document or use an editor that modifies existing content. For a real interactive form field, use Fill PDF Forms; an overlay does not update that field's stored value. |
| You need repeated page numbers, a watermark or a visual mark. | Use the dedicated numbering or watermark tool for those layouts, or Annotate PDF for highlights and boxes. This editor repeats one plain line without page-dependent variables. |
Add Reviewed copy to sample pages 1 and 3
The five-page sample has open space near the bottom of the selected pages. Placing a new label there makes it easy to compare the added text with the unchanged original content.
- Choose device-document-lab.pdf and select Load PDF pages. Enter 1,3 in Pages to update.
- Set Text to add to Reviewed copy and Font size to 18 pt. Set From left to 20 mm and From top to 260 mm, retaining the dark green colour #173c2e.
- Select Add text and then Download PDF. Check that the result reports 5 PDF pages and 2 updated pages.
- Open the output and inspect the lower area of pages 1 and 3. Search for Reviewed copy and check pages 2, 4 and 5 were not labelled. Compare the existing text and page-1 form with the source.
Expected result. The PDF should still have five pages, with a new Reviewed copy line on pages 1 and 3 only. The new line is PDF text rather than a page image. Original wording is not replaced, and the sample does not establish preservation of every possible interactive PDF feature.
Check the downloaded result
- Open the generated PDF to judge placement. Input thumbnails are not a live layout preview; the output is parsed for validity, not automatically checked for overlap or correct meaning.
- Check the entire added string, including punctuation. The new text is restricted to printable ASCII: accented letters, curly quotes, emoji and other unsupported characters are replaced by question marks.
- Inspect each selected page at a readable zoom. A line that fits one page can cover a footer or field on another, even when both have the same dimensions.
- Review the original wording as well as the note. A reader should not have to guess which of two conflicting values is correct. Keep signed and source versions separately from an annotated working copy.
Troubleshooting
- The tool says the text is too wide or does not fit.
The complete line must fit between the left offset and the page edge. The vertical position must also leave room for the font's height; text is not wrapped onto another line.
Try this: Shorten the wording, reduce the font size or move the position. Test the smallest selected page. Use a fuller document editor for a paragraph rather than shrinking it until it is unreadable.
- A name or punctuation mark becomes a question mark.
The worker replaces characters outside printable ASCII before drawing the new line. This includes many characters that the browser's input field allows you to type.
Try this: Use supported wording only when the substitution is acceptable, or choose an editor with the required script and font support. Do not silently alter someone's name or an important reference to make it fit.
- My earlier note is missing after I change the settings.
Start over creates another result from the currently selected input, not from the previous output. Each run adds one line configuration to its selected pages.
Try this: If multiple different notes are needed, download and inspect one result, then select it as the next input. Retain the original; this tool has no multi-note editing history.
Limits and compatibility
- Text and placement
- New text uses a built-in Helvetica font, one line of up to 500 characters and sizes from 6 to 96 pt. Positioning uses millimetres within the visible crop area, accounting for supported right-angle page rotation. Font metrics determine the baseline, so inspect the actual glyph placement.
- What an edit does not prove
- Local processing creates a separate PDF within device limits. It does not validate statements, authorise changes, remove sensitive source content or preserve a signature's validity. Protected PDFs must be unlocked with a known password before this editor can load them.
Your files and form values are processed on this device. Downloaded copies remain wherever you save them. See how to check local processing and our privacy policy for site data and optional services.
Common questions
- Can I click an existing word and change it?
- No. The interface adds text at numeric coordinates. Original text, images and layout are not directly selectable for editing here.
- Will the added line populate a PDF form field?
- No. It becomes visible page text rather than a field value. Use Fill PDF Forms if the document has supported fields and the recipient needs their stored answers.
