Optimize your PDFs for the perfect reading experience on tablets and mobile devices.
It's perfect for two main tasks: removing large white margins to fit text onto smaller screens, and splitting scanned spreads (where two book pages are on one PDF sheet) into individual, vertical pages for a natural reading flow.
Yes, it is 100% secure. Like all Max-PDF tools, the entire process happens locally in your browser. Your files are never uploaded to our servers, ensuring that your books and private documents remain on your device and under your control.
Yes. Use 'Split Vertically' for standard book spreads (left and right pages). Use 'Split Horizontally' for documents that are stacked vertically. This flexibility allows you to handle various scanning formats with ease.
You can enter precise values for Top, Bottom, Left, and Right margins in millimeters (mm). For example, entering '15' in the Left box will trim 15mm off the left side of every page, allowing for granular control over the final layout.
No. Max-PDF uses a
lossless method.
Powered by the
pdf-lib
engine, we adjust the PDF's 'MediaBox' (viewable area) rather than re-encoding the content. Your images and text remain at their original high resolution with zero degradation.
Cropping margins makes text larger on your screen, minimizing the need to zoom in and out. Splitting spreads ensures that page-turn animations work correctly and text is legible, significantly improving your reading efficiency and battery life.
The quality of digital reading is defined by the layout. Scanned artifacts like uneven margins or combined pages are barriers to focus.
Max-PDF removes these barriers with advanced client-side PDF manipulation. By keeping your data local and the process simple, we turn your cumbersome PDFs into perfect e-books in seconds.
