What happens to a WebP in the PDF
WebP is the format many websites serve pictures in, so a right-click and "Save image" often gives you a .webp file that older programs and some upload forms do not accept. PDF has no WebP support either, so every WebP is decoded by your browser (all current browsers open WebP) and stored in the PDF as a JPG at quality 92, up to 6000 pixels on the long side. A transparent WebP gets a white background, because JPG has no transparency; an animated WebP contributes its first frame. With "Smaller file" on, images are scaled to 2000 pixels on the long side and saved at quality 80.
If you want the pictures as single files instead, the WebP converter turns them into JPG or PNG. For a PDF you already have, Compress PDF makes it smaller and Merge PDF joins several files.
Order, rotation and page size
Drop all the images at once and drag the thumbnails into the order you want, or use the arrows. A4 and Letter put each image on a standard page with a margin; Fit to image makes every page the shape of its picture, which suits product shots and artwork. Fill page scales an image until it covers the whole page and cuts off the overhang, for full-bleed pages without white borders.

Frequently asked questions
Is the WebP quality kept?
The image is decoded and saved again as a JPG at quality 92, which keeps the detail of a web image. A lossless WebP loses a little in that step; for pixel-exact graphics, convert it to PNG first with the WebP converter and add the PNG, which is stored losslessly.
What about transparent WebP images?
They are stored as JPG, so the transparent areas become white. If the transparency matters, convert the WebP to PNG first and use that; PNG files keep their transparency in the PDF.
Does an animated WebP work?
Yes, but only its first frame goes into the PDF. A PDF page is a still image.
Are my images uploaded?
No. Decoding and writing the PDF happen in your browser, on your device.
