# Why can't I just edit this PDF?

> You want to fix one typo, and the PDF won't let you. It isn't being difficult on purpose. A PDF is closer to a printout than to a document.

A Word document stores paragraphs. When you add a word, the paragraph reflows, the next line moves down and the page breaks adjust. A PDF stores the result of that process: this glyph, in this font, at these coordinates. There are no paragraphs to reflow, only positioned characters. Edit a word and nothing around it knows it should move.

*A PDF page is a stack of drawing instructions: text, vector shapes and images on a fixed page.*

## Four reasons a PDF resists editing

1. **Fixed layout.** As above, there is no flow. Replacing "two" with "three" means the rest of the line has to be pushed along by hand.
2. **Font subsets.** To keep files small, PDFs usually embed only the characters actually used. If the document never used a capital Q, the embedded font has no Q, and an editor has to substitute a different font.
3. **Scans.** In a scanned PDF there's no text at all, just pictures of it. Editing means painting.
4. **Permissions.** Some PDFs carry restrictions on editing, printing or copying, set by whoever created them.

## What you can actually do

- **Go back to the source.** If you or a colleague have the original Word, Pages or InDesign file, edit it and export again. It's the only way to get a clean result for anything more than a word or two.
- **Cover and retype.** For a small correction, place a white box over the old text and type the new text on top. In [PDF Studio](https://pdfjade.com/studio), use the *Whiteout* element, then add a text box and match the size. The original text is still underneath, so don't use this to hide confidential information.
- **Add rather than change.** Notes, dates, names on a form: [Add text](https://pdfjade.com/add-text-to-pdf) or the Studio handle these without touching the existing content.
- **Extract and rebuild.** For a long text-heavy document, [extract the text](https://pdfjade.com/pdf-to-text), paste it into a word processor and rebuild the layout. Tedious, but reliable.
- **Use a full PDF editor.** Desktop editors can modify existing text in place, with varying success depending on the fonts. For frequent, serious editing, they're worth it.

## The upside

The same rigidity that makes a PDF annoying to edit is why it's trusted for contracts, invoices and forms: what the sender saw is what you see. Every editing tool, ours included, works by adding to that fixed page rather than rewriting it.
