How it usually goes

Elsewhere, step one is an upload.

Most PDF tools are websites. Your file goes to their server, gets processed there, and comes back. Whatever the privacy policy says, your contract has now been on someone else's computer.

With Hush

With Hush, there is no step one.

Hush PDF is a Chrome extension, not a website. Every tool runs inside a tab on your machine. Switch Wi-Fi off first if you like: it keeps working, and the Network panel in DevTools stays empty.

Free, no limits

Merge, split, reorder. Right here.

Drop files in, drag pages into order, combine them into one, or turn one into many and get a single ZIP. Bookmarks survive the trip. No watermark, no page cap, no daily quota.

Pro

Redact means gone, not covered.

Draw a black box. On save, that page is rebuilt as an image with the box burned in. The text underneath is removed from the file, not hidden behind a rectangle, and Hush checks the result before it writes a byte.

Pro

Scans become searchable.

A scanned page is a picture. Hush reads it with a bundled OCR engine (English and Turkish), lays an invisible text layer over the image, and Ctrl+F works in any reader. The page never leaves the device.

Don't take our word for it

Verify it in two minutes.

  1. Go offline. Open Hush PDF once, then turn Wi-Fi off. Merge, split, clean, OCR or redact a file. Everything still works.
  2. Watch the Network panel. Open DevTools on the extension page, clear the log, work with a PDF. Filter for http. Nothing appears.
  3. Read the permissions. In chrome://extensions, Hush asks for one thing: storage, a few bytes for your Pro status. No site access, no downloads, no tabs.

The one exception: buying Pro or restoring a purchase talks to ExtensionPay, only when you click it, and never with your files. The zero-request claim is asserted by the end-to-end test suite on every release; see TRUST.md.

Questions

Asked before you ask.

Does Hush PDF upload my files?

No. Every operation — merge, split, edit, OCR, redaction, compression, password protection — runs inside the Chrome extension on your device. The only network call is the optional ExtensionPay purchase/restore, which never carries your files.

Is Hush PDF free?

Yes. Merge, split, images to PDF, page reorder, hidden-data cleaning and opening protected PDFs are free with no limits. Pro tools (editor, signature, forms, OCR, redaction, compression, password protection, table export) are a one-time purchase — no subscription.

Is there a free trial?

Yes. Every Pro tool can be tried free for 7 days. ExtensionPay asks for an email to start the trial (one trial per email, no card), and trial status is cached on your device so it works offline.

Can Hush PDF redact a PDF permanently?

Yes. Redacted pages are rasterized and rebuilt, so the text under a black box is removed from the file, not just covered. Hush verifies this before saving.

Does OCR work offline?

Yes. The OCR engine (Tesseract, English and Turkish) is bundled inside the extension. Scanned pages become searchable without leaving your computer.

Can I remove metadata and hidden data from a PDF?

Yes. Hush shows the author, dates, XMP, attachments and scripts a PDF carries and removes them in one click, with a before/after report.

Can Hush PDF convert PDF to Word or Excel?

Partially. It extracts detected tables to CSV/XLSX and plain text to .txt/.docx. Page layout is not preserved; it is not a full PDF-to-Word converter.

What permissions does the extension need?

Only "storage", used for the local Pro status. No host permissions, no downloads permission, no telemetry.

Why doesn't Hush open PDF links or replace my PDF viewer?

Because that would need permission to read every page you visit. Hush asks only for storage, so you open a PDF by choosing or dropping the file into Hush yourself — the extension never watches your browsing.

Which browsers are supported?

Google Chrome (Manifest V3). Chromium-based browsers that install Chrome extensions generally work, but only Chrome is tested.
