Edit PDF Text

Edit text in a PDF: add new text boxes, choose font, size, bold and italic, mask old content with a white background and drag lines into exact position.

Edit PDF Text lets you add new text boxes to any page of a PDF, choosing font, size, bold and italic styling, then position each line exactly where you need it by dragging. It is built for making direct text edits to a PDF — correcting a typo, updating a date, or adding a missing line — without needing the original source document.

A white-background masking option covers old text underneath your new line, giving the effect of replacing content even though PDFs don't support true in-place text editing at the character level. Everything renders with the standard fonts Helvetica, Times and Courier, embedded directly into the exported file so it displays identically in any PDF reader.

How to use the Edit PDF Text

  1. Upload the PDF you want to edit.
  2. Click on the page where you want to add or replace text to create a text box.
  3. Type your text and choose the font, size, and bold or italic styling.
  4. Enable the white background option if you need to cover existing text underneath.
  5. Drag the text box into its exact position on the page.
  6. Export the edited PDF once every change on every page is complete.

Why use this tool

Covers and replaces old text

The white background option masks existing content so new text visually replaces the old line without leaving overlapping characters.

Font and style control

Helvetica, Times and Courier are available with bold and italic variants, letting new text match the surrounding document reasonably closely.

Precise positioning

Text boxes can be dragged pixel by pixel, so a correction lines up exactly where the original text sat.

Works page by page

Every page of a multi-page PDF can be edited independently before a single export produces the finished document.

Common use cases

How replacing text actually works

PDF text edit tools like this one add new text on top of the page rather than rewriting the underlying text stream, since PDFs store text as fixed positioned glyphs. Covering old text with a matching background colour and adding new text over it achieves a visually identical replacement.

Font matching limitations

Only Helvetica, Times and Courier plus their bold and italic forms are available. If the original document used a distinctive custom font, an exact visual match is not possible, though picking the closest of the three keeps changes unobtrusive.

Edit PDF Text vs Acrobat Pro

Acrobat's paid Edit tool can sometimes edit original text runs directly, but requires a subscription. This free browser tool covers the common case of adding or masking text without that cost.

Tips for a clean result

Zoom in before dragging text boxes into place for pixel-accurate alignment, and match the font size to nearby text by eye — a mismatched size is usually the first thing that gives an edit away.
