Edit the text of a PDF online for free

Edit the text of a PDF for free: the short answer

Open the PDF in the tool above, choose Edit text, click the line you want to correct and retype it. Click Apply, check the result, then save. The line is rewritten in place, in its original font, size and colour. It is free, with no account, no watermark and no page limit, and the file never leaves your device: everything happens in your browser.

This guide explains what the tool can do and what no tool can do cleanly, how to keep an identical font, what to do when a line will not let you edit it, and what to check before touching an official or signed document. The same free PDF reader also exists as a desktop app, for working offline.

Editing, annotating or redacting: three different actions

People say « edit a PDF » for three operations that have nothing in common. Telling them apart saves you from picking the wrong tool.

• Editing the text changes the content of the document: the original line disappears and a new one takes its place. The recipient only sees the result.
• Annotating adds a layer of remarks on top of the document: highlights, comments, stamps. The original text stays intact and visible. To review a contract or point out a mistake to its author, this is the right action: see our guide to annotate a PDF for free.
• Redacting permanently removes a piece of information and replaces it with an opaque block. To anonymise a document before sending it, use the tool to redact a PDF: covering text with a black rectangle does not erase it, it can still be copied underneath.

A simple rule: if the recipient needs to know something was corrected, annotate; if the correction simply needs to be made, edit; if the information must disappear, redact.

How to edit the text of a PDF, step by step

1. Drop the PDF into the reader at the top of this page, or pick it from your files.
2. In the tools menu, choose Edit text.
3. Click the line to correct: it becomes an input field. Retype the text, then confirm.
4. To add text that was not there, click an empty area of the page and type.
5. Repeat for every line you need. Until you apply, each change stays pending and can be undone.
6. Click Apply, check the result carefully, then Save to download the edited PDF.

The document is rewritten in your browser, without going through a server. No watermark is added, and the resulting file opens normally in any PDF reader.

Keeping the original font: how it works

The Document fonts panel tells you in advance, for each font, which of these sources will be used. You know before applying whether the result will be perfect or just very close.

1. The font embedded in the PDF, if it contains every character you type. This is the ideal case: the line is identical to the rest of the page.
2. The same font installed on your computer. A PDF often embeds only the letters it already uses: if you add a « z » that the document never used, the embedded font is not enough.
3. The same font, if it is free to use and downloadable. It is then fetched for the occasion.
4. As a last resort, a font with the same metrics, such as Carlito for Calibri or Liberation Sans for Arial. The line keeps exactly the same length, even if the shape of the letters differs slightly.

When a line will not let you edit it

The PDF is a scan

A scanned or photographed document is only an image: it contains no line of text to retype. You can add text anywhere on it. Optical character recognition makes it searchable and copyable, but the text you see is still an image.

The new text is longer than the original

Text is not reflowed as in a word processor: each line is replaced in place. If your correction overflows, rephrase it more briefly, or add a line of text underneath.

A character does not show

The tool handles the Latin alphabet with all its accents, and Greek and Cyrillic in most fonts. The rare characters that no available font can write, such as emoji, are replaced, and the interface warns you before you apply.

What you really want is the text itself

To rework a long passage in a word processor, it is simpler to extract the text from the PDF, edit it there, then produce a new document.

The most common corrections, and how to get them right

Most text edits in a PDF look alike. Here are the cases that come up most often, with the right way to handle each one.

Changing a date

Updating the date on a letter, a quote or a document template is the simplest case: a new date almost always has the same length as the old one, and uses digits already present in the embedded font. Just check the document's format (« 25/09/2026 » or « 25 September 2026 ») so you do not mix two on the same page.

Correcting an amount on your own quote or invoice

A typing mistake in a document you issued is corrected line by line. Remember the amounts that depend on it: net total, VAT, gross total, and sometimes the amount written out in words. An invoice already sent to a customer is not touched up: it is cancelled with a credit note and replaced by a new invoice, with its own number.

Replacing a name, an address or a number

A change of address, a new contact person, an updated phone number: these are short lines, easy to retype. First find every occurrence with the reader's search, so you miss none, especially in the header and footer of each page.

Fixing a spelling mistake

A typo spotted just before sending is fixed in seconds, without going back to the source file. If the document will keep evolving, carry the correction over to the original Word file or template: the PDF is only a snapshot of that file at a given moment.

Completing a document that has no fields

A form designed for printing, with no fillable areas, is completed by adding text: click where you want and type. If the document is a real PDF form, with fields, fill in those fields instead: the result is cleaner and stays readable by the software that processes the form.

Free online, licensed in the desktop app

In the browser, on this page, editing text is free and unlimited. Adding text to the page is free everywhere.

Certyneo Reader also exists as a desktop app for Windows and Linux, which works offline and can become your default PDF reader. In that app, retyping existing text is part of Certyneo Reader Pro, along with OCR in 48 languages and conversion to Word, Excel and PDF/A: €29 excl. VAT for one year paid once, with no automatic renewal, €2.99 excl. VAT per month with no commitment, or €24 excl. VAT per seat per year for a team. Reading, annotations, OCR in French and English and the app's other tools stay free.

The app installs in a couple of minutes on Windows 11 and Windows 10, needs no account, and is a practical alternative to Adobe Reader for everyday reading, annotating and assembling of documents.

Editing an official or signed document: the limits

Fixing a typo in your own quote, updating a date on a template or completing a badly designed form are normal uses. Changing the amount on an invoice you received, the salary on a payslip or the date on a supporting document to deceive someone is something else: it is forgery, a criminal offence, whether the document is on paper or in PDF.

Such edits are also far easier to detect than people think. A substitute font, irregular spacing, a mismatch between the visible text and the structure of the file: our tool to detect a modified PDF lists these clues and circles them on the page.

An electronically signed PDF cannot be touched up without consequence either: the signature seals the content, and any later change is flagged by verification software. To correct a contract that has already been signed, produce a new version and have it signed electronically again. To show what changed between two versions, the tool to compare two PDFs highlights the lines added and removed.
