How to convert images to a PDF, step by step

1
Choose the photos you want in the PDF
Tap "Choose images" and select your JPGs or PNGs — up to 100 at a time. On a phone you can pick straight from your camera roll or from Files; on a desktop hold Ctrl or Cmd to select several at once. Tap the button again to add more later, and remove any image with the × beside its name. Picking the same photo twice adds it once — the tool says so rather than quietly giving you the same page again.
2
Put the pages in the right order
Each image becomes one page, in the order shown in the Page order list. Phone galleries hand files over in whatever order they feel like, so check it: every row has a thumbnail and up and down arrows, because filenames like IMG_4821 tell you nothing about which photo is which.
3
Tap Convert to PDF
The PDF is built inside this browser tab using your own device, so a handful of photos takes a second or two and a batch of large scans takes a little longer. Nothing is uploaded and no progress bar is waiting on a server.
4
Download it, or turn it into a shareable link
Your PDF appears as images.pdf with a Download button — tap that first, because the file only exists inside this tab until you save it. If it then needs to reach someone else — a landlord, a claims handler, an admissions office — "Share it as a link" takes you to the uploader, where you pick the PDF you just saved and get a clean URL plus a QR code. That step does upload the file and needs a free account, but whoever opens the link needs nothing at all.

Your photos never leave your device

Almost every other JPG-to-PDF site works by uploading your images to a server, building the PDF there and sending a file back. This one doesn't. The conversion runs inside this browser tab: your pictures are read straight from your camera roll or disk, embedded into a new PDF in the tab's own memory, and returned to you as a download. None of that image data is transmitted anywhere, so there is no upload queue, no temporary copy sitting on someone else's hardware, and no retention policy to take on trust.

That matters because of what people actually photograph and convert: a passport page, a driving licence, a signed form, a utility bill, a set of receipts for an expense claim. Put the page into aeroplane mode once it has loaded and the conversion still works — which is the simplest proof that nothing is being sent anywhere. If you later choose Share it as a link, that step does upload the PDF you saved, because a link needs somewhere to point — but that is a separate, deliberate step you take on the uploader, with a free account.

The honest limits

Running on your device is the whole advantage, and it is also where the limits come from. The images you pick have to add up to 40 MB or less, and there can be at most 100 of them, because building a PDF in a tab takes several times the input size in memory and a phone browser quietly kills a tab that asks for too much. Refusing up front with a message beats freezing halfway through.

Over 40 MB, or over 100 photos? Convert in two batches, then join the results with Merge PDF. The output of one pass is an ordinary PDF you can feed straight back in.
JPG and PNG only. HEIC, WEBP, TIFF and RAW files are skipped rather than mangled, and one renamed to .jpg is caught by its contents and named in the message. Export them as JPG first.
Pages match the image, not A4. Each page is sized to its own photo, so nothing is cropped or letterboxed — but there is no A4 or Letter option and no margin control yet.
Nothing is compressed. The PDF is about as big as the photos that went into it — ten 4 MB camera shots make a roughly 40 MB PDF, which is normal. PNGs are repacked losslessly on the way in, so a PDF made from PNG screenshots can come out larger than the files you started with.
No OCR. A photographed page becomes a picture of text, not searchable or selectable text. For a receipt or an ID that is fine; for something you need to search, scan it properly.

Questions about converting images to PDF

Are my photos uploaded anywhere when I convert them?

No. The PDF is assembled inside your browser tab, using your device's own processor and memory. The images are read from your disk or camera roll, embedded into a new PDF in the tab's memory, and handed back as a download. Your pictures are never transmitted — not to Link in Seconds, not to anyone else — so there is no copy on a server for anyone to keep or delete. You can switch your phone to aeroplane mode after the page loads and the conversion still works, which is the simplest way to prove it. To be exact about the one thing that is sent: the page records anonymous usage the way any website does, so we can see that a conversion happened and whether it failed — never the pictures, their names or their contents.

Which image formats can I use?

JPG (also called JPEG) and PNG. Anything else is skipped with a message rather than silently dropped, and the format is judged by what is actually inside the file rather than by its name — so a file renamed to .jpg is caught by name, before it can produce a mystery failure. The common surprise is HEIC, the format newer iPhones shoot in: when you pick a photo through the iOS photo picker, Safari usually hands the browser a JPG copy and it just works, but an .heic file picked out of the Files app is refused with a note rather than a mystery failure — and if it has been renamed to .jpg, the message names the photo. To fix that permanently, set Settings → Camera → Formats to "Most Compatible", or open the photo and export it as a JPG first.

Does converting reduce the quality of my photos?

No, nothing is ever thrown away. A JPG is copied into the PDF byte for byte — no resizing, and no second round of lossy compression on top of the one your camera already applied. A PNG is unpacked and repacked into the PDF's own lossless format, so every pixel survives exactly, but the page can end up noticeably larger than the .png file you started with. Either way the tool cannot make your photos smaller: for JPGs the PDF is roughly the sum of the images you picked, and for PNGs it can be bigger. If you need a small file, shrink the images before converting, or export them as JPGs first.

What page size does each image get — is it A4?

Neither A4 nor Letter: each page is made to match its image exactly, so the photo fills the page edge to edge with no white margin and nothing is cropped. Portrait and landscape shots can therefore sit in the same document at different page sizes. When you print or open the PDF, your reader or printer scales each page to fit the paper, so a mixed batch still prints sensibly.

How many images can I convert, and how big can they be?

Up to 100 images in one go, and they have to add up to 40 MB or less. Both ceilings exist because the work happens on your device: a browser tab that asks for too much memory is killed silently, and every extra photo is another page to build and another thumbnail to decode. Twenty or so phone photos usually fit comfortably under the size limit. If you are over either limit, convert in two batches and then combine the two PDFs with the Merge PDF tool — the output of one pass is an ordinary PDF you can feed straight back in.

Do I need an account, and will there be a watermark?

No account, no watermark, no daily cap and no email address. Because nothing is processed on a server there is nothing for us to meter, so you can convert as often as you like. You only need a free account if you go on to turn the finished PDF into a shareable link, which is a separate, deliberate step.

Sending the photos on afterwards

Converting is usually step one — step two is getting the file to whoever asked for it. If the PDF is a stack of camera shots it can easily be too heavy for an inbox, and the guide on how to send a large PDF covers the 25 MB email wall and what actually gets past it. And if a PDF wasn't really the goal — you just needed someone to see the pictures at full resolution — sending a batch of photos without losing quality is the better route, because messaging apps crush images that a link leaves untouched.
