Why it's a strong pick

Simple VaultPDF edits PDFs inside Chrome and does not upload them. It is open source under the MIT licence, uses Manifest V3 and needs no account. Its permissions are storage, offscreen and unlimitedStorage, and nothing else, per the repo manifest and PRIVACY.md. The Chrome Web Store shows version 1.2.0, updated 18 September 2026. The trade-off: it is a small, new project with one developer.

What it does

It is a PDF editor that runs locally in Chrome. You can read a PDF with zoom and a page indicator, reorder, rotate, restore and delete pages, merge several PDFs, and pull selected pages into a new PDF. It can also save the current page as a PNG or JPG, and extract text. For scanned pages it runs OCR on your device.

Key features

  • Local processing. Files are not uploaded.
  • Page tools. Reorder, rotate, restore and delete pages.
  • Merge and extract. Combine several PDFs, or extract selected pages into a new PDF.
  • Page to image. Save the current page as PNG or JPG.
  • Text extraction and OCR. Copies the embedded text layer, or runs local Tesseract.js OCR on scanned pages, with an optional Force OCR.
  • OCR languages. English and Hungarian models are bundled. Other languages download once, after you click, and are stored in IndexedDB.

Who it's for

Simple VaultPDF is for people who want to merge, reorder or OCR a PDF without sending it to a website. It suits private documents. If you only want to read PDFs, see PDF Viewer (PDF.js). For full editors from large vendors, see Adobe Acrobat.

What is Simple VaultPDF?

Simple VaultPDF is a Chrome extension for working with PDFs on your own computer. You can read, reorder, merge and extract pages and run OCR without uploading the file. The developer is opzozi, and the code is public on GitHub under the MIT licence. It is a new, small project run by one developer.

Does Simple VaultPDF upload my files?

No, according to the developer. The listing and README say the files are not uploaded, and the Chrome Web Store says the developer will not collect or use your data. These are the developer's own statements, not an audit by us. One download exists: if you pick an OCR language other than English or Hungarian, the model downloads once after you click.

What permissions does Simple VaultPDF ask for?

Three, from the repo manifest and the PRIVACY.md file: storage, offscreen and unlimitedStorage. It asks for nothing else. Chrome shows the final list when you install, so check it there. We did not audit the code, and the permission list may change in a later version.

Is Simple VaultPDF open source, and what does it cost?

It is open source under the MIT licence, and the listing links the repository. On price, the listing and README show none. The developer asks for optional donations. We do not call it free beyond that. It needs no account, per the listing.

FAQ

Does it work with Manifest V3? Yes. The repo manifest sets manifest version 3 and uses a service worker.

Does OCR work offline? The OCR runs on your device. English and Hungarian models are bundled. Other languages need a one-time download.

Who makes it? A single developer, opzozi. The listing's website is opzozidev.com.

Good to know

Limits: this is a small, new, one-developer project, so check the repository's activity before you rely on it for important work. Per the README, encrypted or otherwise uncopyable pages are merged as images, so the text on them is not selectable afterwards. Practical tip: if you need searchable text from those pages, run OCR on the merged result.
