How to Turn Multiple Photos Into One PDF, In the Right Order

Turning a folder of photos into one ordered PDF is a short process, four real settings and a click. This walks through exactly what JPG to PDF does at each step, including the two things it does automatically that are worth knowing about.

Step 1 - drop your images

JPG, PNG, or WebP, up to 30 images at once, each up to 60MB. Anything unsupported, or over that size, is skipped with a plain message naming which file and why, and the rest of the batch keeps going rather than the whole thing failing over one bad file.

Step 2 - reorder them

Each image appears as a row with move-up and move-down buttons, keyboard-operable, not pointer-only. Whatever order the list is in when you click Create PDF is the page order in the finished file, page 1 at the top of the list. There's no drag handle, on purpose: click-to-move is faster to get exactly right than dragging, especially with more than a handful of images.

Step 3 - set the page size, orientation, and margin

Three real options for page size: A4, Letter, or "Fit image", which sizes each page to that image's own proportions instead of a fixed standard size, useful when your photos are an odd shape and you don't want blank space padding every edge. Orientation has three settings too: Auto decides portrait or landscape per image based on its own width and height, or you can force every page to Portrait or Landscape regardless of the source photo's shape. Margin is a slider from 0 to 40mm, 10mm by default, a small buffer around each image so nothing sits flush against the paper edge.

What orientation actually controls

Worth being precise about what this setting does: it decides the shape of the page itself, portrait or landscape, not the rotation of the photo's content. A phone photo that merely carries a note saying how to turn it (its EXIF orientation) needs nothing from you: the tool reads the note and stands the picture upright on the page, as your gallery shows it. A photo whose pixels were themselves saved sideways, with no such note, is a separate fix, and not something the page-size or orientation controls do for you. Image crop's rotate and flip toolbar handles exactly that: open the sideways photo there, rotate it upright, download the corrected version, then drop that into JPG to PDF instead of the original.

The margin slider, in practice

0mm places the image flush against every edge of the page, right for a "fit image" page where you want the photo to fill the entire sheet with nothing wasted. Something in the 10 to 20mm range reads as a normal, deliberate document margin, the default the tool starts with. Pushing toward 40mm gives a generously bordered, more formal look, useful if the PDF is going to be printed and handled physically rather than just viewed on screen.

What happens on a large batch

With close to the 30-image limit, the process runs in two visible phases: images are prepared on the main thread first (decoded, and downscaled or converted to JPEG where needed), then the actual PDF is assembled inside a background worker. Both phases show progress as they go, so a large batch doesn't leave you staring at a frozen page wondering whether anything is happening.

Step 4 - click Create PDF

Three things happen automatically here that are worth knowing about. First, WebP images have no native path into the PDF format this tool uses, so any WebP photo is decoded and re-encoded as a JPEG at 90% quality before it's placed on the page, visually identical, just a different file format under the hood. Second, any image above a sane resolution ceiling gets scaled down before it's embedded, since a full-resolution 12-megapixel phone photo would make for a needlessly large PDF that's slow to email and slower to open, with no visible improvement over a more reasonably sized version. Third, a phone photo that carries a rotation note (EXIF) is redrawn upright before it is placed, because a PDF reader ignores that note; a JPEG with no rotation goes in exactly as it came, byte for byte. The actual document build then runs inside a background worker, not the page's main thread, so a batch of 20 or 30 images doesn't freeze the tab while it works.

Step 5 - download

The result is a genuine multi-page PDF, one image per page, in the order you set. Open it in any PDF viewer and it behaves like any other document: scrolls, prints, and looks the same regardless of who opens it or on what device. This version places exactly one image per page rather than arranging several onto a single sheet, so a batch of ten photos always produces a ten-page document, predictable regardless of how differently shaped or sized the source images were.

If something doesn't look right

An image that came out rotated the wrong way in the PDF means its pixels were saved sideways with no rotation note (a note, when there is one, is applied automatically); fixing the orientation of the source photo first (most phone galleries can rotate and re-save a photo in a couple of taps) is the fix, since this tool places each image the way it reads once any note has been applied. If a page looks unexpectedly small or has a lot of blank space around a tall, narrow photo, "Fit image" mode usually looks better than a fixed A4 or Letter size for that particular shape. And if the order still looks wrong after reordering, double-check you clicked the arrow on the row you actually meant to move, each up/down button moves only its own row, one position at a time, so a fast series of clicks on the wrong row is a more common mistake than a real bug.

Try it on your own photos and you'll have a finished PDF before you'd have finished attaching the individual images to an email.
