    Frequently asked questions

    Are my images uploaded to a server when I convert them?

    No. The PDF is built locally in your browser using the pdf-lib JavaScript library. Your images are never uploaded anywhere.

    Can I mix JPG, PNG and WEBP images in the same PDF?

    Yes. You can combine any mix of JPG, PNG and WEBP images — they'll all be placed into the same PDF, one per page.

    Can I reorder the images before converting?

    Yes. Use the up and down arrows next to each file in the list to set the order you want before converting.

    What page size is used for the PDF?

    By default, each page is sized to exactly fit its image, so there's no cropping or stretching. If you'd prefer a standard size, choose "A4 (fit within margins)" from the page size option, which centers each image on an A4 page instead.
