Short version: open the free tool, drop your file, download the result. Nothing is uploaded.

Steps

Open the free WBS JPG to PDF tool.
Select all the images at once (Ctrl or Cmd-click, or Shift-click a range), or drop them on the page.
Put them in order: use the ↑ ↓ arrows, or Sort A–Z to order them by file name (numbers sort naturally, so page2 comes before page10).
Choose a page size and press Make PDF. You get one PDF with one image per page.

Typical uses

Several phone photos of a paper document, turned into one PDF to email or upload to a portal.
Receipts for an expense claim.
Screenshots of a conversation or an order, kept as one file.
Pages of a handwritten assignment a teacher wants as a single PDF.

Getting the order right

The PDF follows the list from top to bottom. If your files are named by the camera (IMG_2041.jpg, IMG_2042.jpg…), Sort A–Z puts them in the order you took them. Otherwise drop them all and fix the order with the arrows, or remove a stray one with ✕.

How many images can I combine?

Up to 20 images per PDF in the free version, with no page-size or file-size limit other than your device's memory. For more, either make two PDFs and join them with PDF Merge, or get WBS Tools Pro ($7 once), which removes the 20-image limit in all the batch tools.

Keeping the file small

Upright JPGs go into the PDF without re-compression, so the PDF is roughly the total size of the photos. If it's too big to email, shrink the photos first with the image compressor (for example to 300 KB each), then make the PDF.

Private by design

Everything happens in your browser. The images aren't uploaded, there's no account and no watermark.
