    Frequently asked questions

    Do my files leave my device?

    No. Each file never leaves the device. This tool reads and processes files entirely in your browser, with nothing uploaded or stored by API Tool Calls.

    Can I change the image order?

    Yes. Move up and Move down change the order. Remove leaves out an image. Each remaining image becomes one page in that order.

    How do page sizes and margins work?

    Fit image uses the image size at 72 pixels per inch plus the chosen margin. A4 and US Letter pages turn portrait or landscape to match each image. The image is scaled to fit inside the margin and centered.

    Which image formats can I use?

    JPG and PNG are embedded in the PDF. Other browser-readable image types are first converted to PNG on your device. Animated images become a single still frame.
