Simply upload your PDF by dragging and dropping it into the upload area or clicking to browse. Once uploaded, all pages will appear as draggable thumbnail cards. Drag any card to a new position to reorder. Click "Download Reordered PDF" to save your newly arranged document. You can also reverse the entire order or reset to the original sequence with one click.

Absolutely. All PDF processing happens entirely within your browser using client-side JavaScript. Your file is never uploaded to any server. We use industry-standard libraries (PDF.js and pdf-lib) to render thumbnails and reconstruct the PDF locally on your device. Your data stays private and secure.

Yes! This tool is fully responsive and supports touch-based drag-and-drop on smartphones and tablets. The thumbnail grid automatically adjusts to fit smaller screens. Simply tap, hold, and drag any page card to reorder on your mobile device.

We recommend PDFs up to 100MB and around 200 pages for optimal performance. Larger files may take longer to render thumbnails. Since all processing is done locally, your device's memory and processing power are the main limiting factors. For very large documents, consider splitting them first.

Yes! Each page card has a rotate button (circular arrow icon). Click it to rotate the page by 90° clockwise. The rotation badge on the thumbnail indicates the applied rotation. Rotations are preserved in the final downloaded PDF, so you can fix page orientation while reordering.

Absolutely. Each page card includes a delete button (X icon). Removing a page is instant and the remaining pages automatically renumber. You must keep at least one page to download. This is perfect for trimming unnecessary pages from your PDF.

Yes. The pdf-lib library preserves the original quality of your PDF content. Pages are copied byte-for-byte from the source document. Text, images, vector graphics, and embedded fonts remain intact. No re-compression or quality loss occurs during the reorder process.

Yes, completely free! There are no hidden fees, no registration required, and no usage limits. You can reorder as many PDFs as you need, as often as you like, directly in your browser without any subscriptions or watermarks.
