Combine as many photos as you like into a single PDF, in the order you choose. The photos never leave your machine, and sideways phone shots come out upright.
Drop in your photos, put them in the order you want with the arrows, pick a page size, and press Make PDF. You get one PDF with one photo per page, sized to fit the page. Phone photos taken sideways are rotated upright automatically, the same way your phone's gallery shows them.
Page order is list order. Photos are added in the order they appear above, whatever order you dropped them in. Use the up and down arrows to rearrange, and the × to drop one out.
Auto orientation matches each page to its photo, so a wide shot gets a landscape page and a tall shot gets a portrait one; choose Portrait or Landscape instead if you want every page the same shape.
Transparency becomes white. PNG and WebP files work fine, but anything see-through is filled with white, because the photos are stored inside the PDF as JPEGs.
Need pages out of a PDF instead? Use Merge & Split PDFs to combine PDFs or pull single pages back out.
This matters most when the photos are documents. You don't have to take our word for it: every browser has a built-in panel that shows everything a page sends or receives over the internet. On a computer (this doesn't work on a phone):
