How to combine photos into one PDF
Add the images, drag them into the order you want, choose a page size, and export once. The result is one PDF with one image per page, which is what an email attachment or an upload form nearly always wants instead of six separate files.
JPG to PDF does this in the browser, with the ordering and the page size in your hands. JPG to PDF
Making one PDF out of several pictures
- Add every image you want in the document. JPG, PNG and WebP are all accepted.
- Drag the thumbnails into the order the pages should be in.
- Choose the page size: A4 or Letter if a person will print it, or match the image if nobody will.
- Choose fit rather than fill unless you actively want the edges cropped.
- Export once, and check the page count before you send it.
Why one PDF instead of several images
Attachments get separated. An office that receives six photographs has six things to keep together and one to lose, and most upload forms accept a single file anyway. One PDF also fixes the order, which a set of files named IMG_2043 does not, and it prints predictably: one picture per page, at a size somebody chose, rather than whatever a photo printer decides.
What the page size choice actually does
A4 or Letter places each image inside a page of that shape, keeping the picture's proportions and filling the rest with white. Match the image makes every page exactly the shape of its picture instead, with no border at all. The first is right for anything that will be printed; the second is better for screenshots or a set of photographs somebody will only scroll through.
Fit keeps everything, fill crops
Fit scales the image until the whole of it is inside the page. Fill scales it until it covers the page, and whatever hangs over the edge is cut off. Fill looks better on a background image and quietly removes the top of a document. If in doubt, fit: a white border never destroyed anything.
What the conversion costs
A JPEG is placed in the PDF exactly as it is, byte for byte, so nothing is lost and nothing gets bigger. PNG and WebP cannot be carried by a PDF in their own format and are converted to JPEG at quality 92, which is lossy. On a PNG screenshot of small text you may see slight softening around the letters.
This is also roughly how the file size adds up: the PDF weighs about what its JPEGs weigh, plus a little structure. Six photographs of three megabytes make an eighteen-megabyte PDF, and no page-size choice changes that. If the result is too heavy to send, the fix is compression, done knowingly, after you have seen the size.
The tool reports what happened rather than leaving you to guess: after an export it says how many images went in without re-encoding and how much image data the file holds, so a surprising size has an explanation attached.
The iPhone problem: HEIC
Recent iPhones save photographs as HEIC, a format this tool does not accept, because browsers themselves cannot reliably decode it. Two honest fixes. On the phone: share the photos rather than copying the files, because sharing converts to JPEG on the way out. Or permanently: in the camera settings, choose 'Most Compatible', and the phone shoots JPEG from then on. Nothing on this page will pretend to open a HEIC and quietly fail halfway.
When a PDF is the wrong container
A form that asks for a photo upload wants an image file, and a PDF will be refused: use the image itself. A photo lab printing pictures wants JPEGs at full resolution, and a PDF only adds a step at the counter. And pictures meant for someone's gallery, holiday photos, a shared album, should stay images: a PDF is for documents, order and printing, not for looking at photographs.
If the pages came from paper
Photographs of documents want straightening and contrast before they want binding together. Scan them first and the pages will look scanned rather than photographed, then you have a document instead of a folder of pictures.

Questions people ask next
How many images can I add?
Nothing here imposes a cap, and there is no account or daily quota. Your device's memory is the practical ceiling, because every image is held at full size while you work. A few dozen phone photographs is comfortable; a few hundred is not.
Will the images be re-compressed?
JPEGs are not: they go in exactly as they are. PNG and WebP are converted to JPEG at quality 92 because a PDF cannot carry those formats, and that conversion is lossy.
Can I reorder pages after adding them?
Yes, by dragging the thumbnails, and it is much faster than removing everything and adding it again in a different order.
Can I mix a PDF in with the images?
No. This tool binds images into a new PDF; it does not merge existing PDFs, and saying so plainly beats letting you find out at the export button. If some of your pages are already a PDF, use the PDF to JPG tool to export those pages as images first, then combine everything here.
Why will it not take my iPhone photos?
They are almost certainly HEIC, which browsers cannot reliably decode, so this tool does not claim to. Share them from the Photos app instead of attaching the raw files, which converts them to JPEG, or switch the camera to 'Most Compatible' so future photos are JPEG from the start.
