You can select as many images as you like. Your browser handles all the processing. However, if you combine hundreds of high-resolution images at once, your device might experience slowdowns due to high RAM usage.

Absolutely not. The image-to-PDF conversion is performed entirely on your web browser using the `pdf-lib` library. Your image data never leaves your device, guaranteeing 100% privacy.

Each image is centered on a standard A4 size PDF page (595 x 842 points). The image is automatically scaled proportionally to fit within the A4 page without cropping, keeping a 40-point margin around it so it looks great when printed.

Yes, absolutely! Once you've uploaded your images, you can hover over any image and use the arrow buttons to move it forwards or backwards. The on-screen order (left-to-right, top-to-bottom) will be the exact page order in your final PDF.
