Does it support files with more than 200 pages?

Yes. The engine rewrites the /Pages tree without duplicating heavy content streams.

How can I organize and change the order of pages in my PDF?

Drag one or more PDF files into the interactive workspace. High-resolution thumbnails of each page render instantly. Drag and drop any card to your desired spot, rotate pages 90°, duplicate them, remove unwanted sheets, or apply automated patterns (like reverse order or duplex interleave). Finally, click «Organize and Download PDF».

Can I combine pages from multiple PDF files in a single session?

Yes. Unlike basic tools, our montage deck allows importing multiple PDF documents at once or adding more files via the «+ Add PDFs» button. All sheets appear in a unified canvas where you can interleave and sequence them freely.

Is there any page count or file size limit when organizing?

No artificial caps or paywalls. By processing documents entirely in your browser RAM using multi-threaded Web Workers and accelerated Canvas rendering, you can smoothly organize large documents with hundreds of pages without restrictions.

Will fonts or vector paths lose quality when organizing the PDF?

Not at all. PDFBlack performs binary restructuring of the `/Pages` object tree strictly following ISO 32000-1 specifications. Embedded fonts, hyperlinks, vector blueprints, and metadata remain 100% intact without rasterization.

How does the duplex scan interleave feature work?

If you scanned double-sided sheets using a simplex feeder (producing odd front sides 1, 3, 5... followed by reversed even backs 6, 4, 2...), the «Duplex» button automatically interleaves them into continuous numerical sequence (1, 2, 3, 4, 5, 6) in one click.

Can I rotate individual sheets, preview in HD, or delete pages?

Yes. Each page card features hover controls: 90° clockwise rotation, quick delete trash action, and an HD zoom eye icon to inspect pages in full detail inside a modal dialog.

Is it safe to organize confidential contracts or healthcare records?

100% confidential and secure. PDFBlack operates with a strict Zero-Knowledge architecture: zero files or data streams ever leave your machine. Everything runs locally in browser RAM, complying with GDPR, HIPAA, and corporate security guidelines.

Can I undo actions if I make a mistake while sorting pages?

You have full Undo and Redo support via the top bar buttons or the universal keyboard shortcuts Ctrl+Z (Undo) and Ctrl+Y / Ctrl+Shift+Z (Redo), with up to 25 history steps in local memory.

Can I insert blank pages or re-number the exported document?

Yes. The «+ Blank Page» button lets you insert empty divider sheets anywhere in the sequence. In the bottom control panel, you can also toggle automated footer page numbering, choosing your preferred template and placement.
