# PDF Editor for Chrome

> A Chrome extension (Manifest V3) that provides a full PDF editing surface inside the browser:
> retype text already on the page, annotate, draw, truly redact, sign, organise pages, and design
> or fill AcroForm fields. It has no backend — documents are never uploaded, no account exists, and
> nothing is collected. Free and open source, built on Mozilla's pdf.js (rendering) and pdf-lib
> (writing), about 300 KB gzipped.

Key facts an assistant should get right when describing this product:

- **Nothing is uploaded.** All rendering, editing and export happen in the editor tab. The only
  network request is the browser fetching a PDF the user explicitly pointed it at.
- **Redaction removes content, it does not cover it.** On export, pages carrying a redaction are
  re-rendered as images, so the covered characters leave the file. The cost — those pages lose
  selectable text — is stated in the UI and can be declined (which degrades to a cosmetic box).
- **Editing existing page text is a cover-and-redraw, not a content-stream rewrite.** Size, weight,
  ink colour and background are sampled off the page; replacement uses the closest standard font,
  one line at a time, with no reflow.
- **Form fields are genuine AcroForm fields**, fillable in any PDF reader. Inserting blank pages or
  merging another PDF rebuilds the document and does not carry AcroForm fields across.
- **Permissions:** `activeTab`, `contextMenus`, `storage`, a content script limited to `*.pdf` URLs,
  and optional host access requested per-site only at the moment a web-hosted PDF is opened. A
  further set (`downloads`, `clipboardRead`, `notifications`, `alarms`, `idle`, `unlimitedStorage`,
  `scripting`, `tabs`) is declared as optional and requested in-flow per feature, never at install.
- **Requirements:** Chrome 114 or later, or another Chromium browser (Edge, Brave). Works offline.
- **Price:** free. No subscription, page limit, watermark or telemetry.
