How does the Tab Order Fix work?

Set the page-level /Tabs entry on every page of your PDF. /Tabs controls the order in which keyboard / screen-reader users tab through interactive elements: Structure follows the document's tagged structure tree (recommended for tagged PDFs and required by PDF/UA), Row goes left-to-right top-to-bottom, Column goes top-to-bottom left-to-right. The default in many PDF authoring tools is no /Tabs entry — which is the worst choice for accessibility because the order is undefined.

🔒 Security & Privacy

All processing happens on your device. Your files never leave your browser, never touch our servers, and are not stored anywhere. Close the tab and the file is gone.

📱 Use it on any device

Works in any modern browser — Mac, Windows, Linux, iPhone, Android, and tablets. No installation, no app to download. Just open the page and start.

⚡ Quick & easy

Drag, drop, click. Most files process in seconds, not minutes. No watermarks added to your output, no per-day limits, and the tool always shows the result before asking you to download.

🎁 Always free, no signup

Free to use, every time. No account creation, no email required, no “trial” that converts to a paid plan. We make money from ads so you don’t have to pay.
