The promise

Your files never
leave your device.

Most “online” PDF tools quietly upload your files to a server, parse them remotely and trust you not to read the terms. We took the opposite path. Everything runs as JavaScript inside your browser tab, where the file already lives.

When you close the tab, the file disappears with it. There is no copy, no cache, no log entry. We could not retrieve your document if we wanted to.

01

Local rendering

The PDF you select is opened in memory by pdf-lib and pdf.js — two open-source libraries that run inside your browser, the same way your email client opens an attachment to show a preview.

02

No server processing

There is no upload step. The progress bar you see is the time your own CPU takes to copy bytes between pages. Our server only delivers the original HTML, CSS and JS — never your file.

03

Automatic cleanup

On reload or close, the JavaScript runtime discards the file along with everything else in tab memory. We use no IndexedDB, no service-worker cache, no localStorage for documents.

Method

Three steps,
then it’s done.

We strip away friction the same way a katana strips away weight: by leaving out everything that doesn’t cut.

  1. 01

    Choose a tool

    Pick from sixteen — merge, split, compress, convert, sign, protect. Each is a dedicated, focused page.

  2. 02

    Add your file

    Drag and drop, or click to browse. Your file is read by the browser and never leaves the page.

  3. 03

    Save the result

    When processing completes, the finished file is offered as a download from your own browser.
