PDF Redaction Studio Desktop

How it works

How PDF Redaction Studio Desktop runs on your computer: the built-in Studio app, opening PDFs from your file manager, where documents are stored and what goes online.

Studio Desktop is PDF Redaction Studio packaged as an app. The installer contains the whole Studio web app. When you start Desktop, it runs Studio on a small web server inside the app, reachable only from your own computer, and shows it in the app window. The document library, background queue, editor and export work exactly as described in How Studio works. This page covers what is different on the desktop.

How PDF Redaction Studio Desktop processes documents on your computer: open PDFs, store them in the app library, queue them, read and detect, review, save the redacted PDFIN THE APP ON YOUR COMPUTEROpen PDFsfile manager,Redact PDF menu,or dropLibraryfile + redactionsin the app dataQueuecredit check,one documentat a timeRead + detecttext layer or OCR,rules, faces,Local or Cloud AIReviewin the editor,saved as you goSave PDFto yourDownloads folderSync (optional):PDF + redactionsCloud AI (optional):page text sent

The app on your computer

  • Studio is built in. The app doesn't load studio.pdf-redaction.com. Its version is the version of the app you installed, and it changes when the app updates, see Install.
  • You sign in when the app starts. E-mail sign-in happens in the app window. Google and Microsoft sign-in open your web browser and hand back to the app when you are done. Your account, workspaces and plan are the same as on the website.
  • One window. Only one copy of the app runs at a time. Links to other websites, such as these docs, open in your default browser.

Opening a PDF from your file manager

When you choose Redact PDF in Windows Explorer, Open With in Finder or your Linux file manager, or drop a PDF on the Dock icon, the file takes a shorter path than one you drop on the dashboard:

  1. Your system hands the file to the app. If the app isn't running, it starts first. If you aren't signed in yet, the file waits until you are.
  2. The app reads the file from disk and adds a copy to the Default project of your active workspace. The file on your disk is never changed.
  3. If the PDF has a password, the app asks for it.
  4. The document opens straight in the editor, which scans it while you watch, instead of waiting in the background queue.

PDFs you drop on the dashboard or add with Open New Document go through the background queue, as in Studio. The menus for each system are listed in Quick start.

Where your documents are stored

The document library lives in the app's own data folder, not in a web browser:

SystemApp data folder
Windows%APPDATA%\Pdf Redaction Studio
macOS~/Library/Application Support/Pdf Redaction Studio
Linux~/.config/Pdf Redaction Studio

The app has its own library, separate from Studio in your browser. A document added in the app doesn't appear in Studio on the web, and the other way round, until you sync it to the cloud and open it on the other side. The AI models are downloaded into the same folder the first time you process a document, and stay there for later documents.

Redacted PDFs you save are written to your Downloads folder as redacted-<original name>.pdf.

What goes online

Desktop needs an internet connection: it checks your account and page allowance with pdf-redaction.com while it works.
