A document, not a pile of pictures
The work in turning images into a PDF is almost never the conversion. It is the order the receipts go in, the one photo that is on its side, the screenshot that has to be readable, and the page size the other end is expecting. So those are the things on this page: drag a page where you want it, turn one a quarter at a time, throw one out, and watch the first page redraw as you change the setup.
That preview is worth a sentence, because it is the difference between one attempt and three. It is not a picture of roughly what will happen: it calls the same two functions that lay out the file, so the page, the margin, the crop and the rotation are exactly the ones you are about to save.
Each picture stored the way that picture deserves
A folder of mixed images has mixed needs, and one global quality slider serves none of them. On Auto, each picture is written twice internally and the smaller one is kept: a photograph ends up as JPEG, where JPEG is excellent, and a screenshot or a logo ends up stored exactly, where JPEG would have smeared the edges. Best keeps everything exactly. Smallest re-encodes everything at a quality you set, for when the file has to fit an email.
One case is handled better than the settings suggest. A JPG that needs no changing is not re-encoded at all: PDF's image filter is JPEG, so the file's own bytes go into the document and the photo costs exactly what it cost on disk. And a picture with transparency keeps it, with the alpha stored beside the colour rather than being flattened onto white.
iPhone photos go straight in
HEIC files do not need converting to JPG first. They are decoded here by libheif, an open-source decoder compiled to WebAssembly and served from this site, which is fetched once the first time one arrives. Mix them with anything else in the same document. HEIC to PDF is the page for that on its own.
Nothing is uploaded, and the document says nothing about you
Every part of this runs in the tab: the decoding, the layout and the writing of the file. There is no address on this site that could receive an image. The document itself carries no EXIF, no GPS position and no creation date, which is the one almost every other writer puts in without asking and which is also why two runs over the same pictures here give you the same file.
The pages for one format at a time are JPG to PDF, PNG to PDF and HEIC to PDF. Going back the other way, PDF to PNG and PDF to JPG turn a document into pictures again.

Questions
Which image formats can I turn into a PDF?
JPG, PNG, WebP, AVIF, GIF, BMP and HEIC, mixed together in one document if you like. HEIC is decoded in the browser by libheif, which is fetched once the first time an iPhone photo arrives. Everything else uses the browser's own decoder.
How do I combine several images into one PDF?
Drop them all in. Each becomes a page, and the order is the order shown: drag a page to move it, or use the arrow buttons. One PDF is the default, so all you do after that is click Save PDF.
Can I change the order of the pages?
Yes, by dragging a page onto the position you want, or with the left and right buttons on each page for keyboard and touch. You can also turn any page a quarter at a time and remove one without starting again.
What page size and margins do I get?
A4 by default, or US Letter, Legal, A3, A5, or a page the shape of the picture itself. The margin is a slider in millimetres, and the preview beside the settings is drawn by the same code that lays out the file, so what you see is what is saved rather than an approximation.
How large will the PDF be?
It depends on the pictures and the quality setting. Auto stores photographs as JPEG and flat artwork losslessly, whichever comes out smaller per picture; Best keeps every pixel; Smallest re-encodes everything as JPEG at a quality you choose. A JPEG that does not need changing is copied into the document rather than re-encoded, so it costs exactly what it did on disk.
Is there a limit on the number of images?
No. Nothing is uploaded, so there is no server cost to cap: the limits are your own device's memory and the few seconds each large picture takes. A picture too large for the device is reduced rather than crashing the tab, and the page tells you when that happened.
Do my images leave my computer?
No. The document is written inside this browser tab. There is nowhere on this site that could receive an image, and the page still works with the browser switched to offline once it has loaded, which is the check worth doing on any site that claims this.
Can I make one PDF per image instead?
Yes, there is a box for it. Each picture becomes its own one-page PDF and they arrive together in a ZIP.
Your files never leave this device
Most online converters upload every file to a server, convert it there and keep it for a while. Here your browser decodes and encodes the picture itself, so there is nowhere for the file to go. You can check it: load this page, switch the browser to offline, and convert a file. How to check a site is not uploading your photos.
